话题背景

关于认证我的个人理解是,验证信息的合法性。在我们生活当中,比如门禁,你想进入一个有相对安全措施的小区或者大楼,你需要向保安或者门禁系统提供你的身份信息证明,只有确定你是小区业主,才可以进来,我这只是打个比方啊,不要纠结。对于我们计算机的安全领域,认证其实也非常类似,windows系统登陆就是一个很好的例子。今天我们主要学习的是ASPNET以及ASPNETCORE平台上面一些主流的认证方式。

正式话题-认证

我最开始接触NET平台的WEB框架是从APSNETWEBFORM开始->ASPNETMVC->ASPNETMVCCORE,下面我们就从WEBFORM开始吧(包括MVC1.x-4.x)。在MVC5之前,我们常用的认证方式有,Forms、Windows、Passport、None这三种认证方式,严格意义上说是三种,None为不认证,而在这三种认证方式当中,我们最常用的就是Forms表单认证,下面我们一起来看看Forms表单认证的实现原理。

Forms表单认证

我会以我自己的使用方式介绍再到实现原理。整个Forms认证的实现逻辑大概是,说到Forms认证我们就不得不说ASPNET处理管道,为什么这么说呢?因为ASPNET的很多基础功能都是通过相应的HttpModule实现的,比如认证、授权、缓存、Session等等。ASPNET平台的Forms认证就是基于FormsAuthenticationModule模块实现,相应的Windows认证也是一样,由WindowsAuthenticationModule实现。对于Forms认证方式登录而言。

1.匹配用户名&密码是否正确。
2.构建FormsAuthenticationTicket对象。

3.通过FormsAuthentication.Encrypt方法加密Ticker信息。
4.基于加密Ticker信息,构建HttpCookie对象。
5.写入Response,输出到客户端。
以上就是我们基于Forms表单认证方式的登录实现逻辑,下面我们来梳理一下认证的大概实现逻辑,针对每次请求而言。
1.在ASPNET管道生命周期里,认证模块FormsAuthenticationModule会接管并读取Cookie。
2.解密Cookie获取FormsAuthenticationTicket对象并且验证是否过期。
3.根据FormsAuthenticationTicket对象构造FormsIdentity对象并设置HttpContext.User。
4.完成认证。
下面我们一起看看Forms认证的具体实现,我会以我自己开发过程中使用的方式加以介绍。首先我们会在web.config文件里面定义authentication配置节点,如下。

 <authentication mode="Forms">
<forms name="AUTH" loginUrl="~/login" protection="All" timeout="" path="/" requireSSL="false" slidingExpiration="true" />
</authentication>

mode属性对应了4属性值,除Forms以外还有上面我提到的三种方式。其他三种由于篇幅问题,在这里不做介绍。这些属性我相信大家应该都比较熟悉。下面我们看看关于Forms认证具体的后台代码。看代码。

 public virtual void SignIn(User user, // 这个user是你校验合法性之后的这么一个用户标识对象
bool createPersistentCookie)
{
var now = DateTime.UtcNow.ToLocalTime();
// 构建Ticker对象
var ticket = new FormsAuthenticationTicket(
,
user.Username,
now,
now.Add(_expirationTimeSpan),
createPersistentCookie,
user.Username,
FormsAuthentication.FormsCookiePath);
// 加密ticker对象
var encryptedTicket = FormsAuthentication.Encrypt(ticket);
// 通过加密ticker对象构建HttpCookie对象
var cookie = new HttpCookie(FormsAuthentication.FormsCookieName, encryptedTicket);
cookie.HttpOnly = true;
if (ticket.IsPersistent)
{
cookie.Expires = ticket.Expiration;
}
cookie.Secure = FormsAuthentication.RequireSSL;
cookie.Path = FormsAuthentication.FormsCookiePath;
if (FormsAuthentication.CookieDomain != null)
{
cookie.Domain = FormsAuthentication.CookieDomain;
}
// 写入输出流Response
_httpContext.Response.Cookies.Add(cookie);
}

以上代码就完成了我们的Forms认证所需的Cookie信息,可能有些朋友在以往开发WebForms到4.x最常用的使用方式是FormsAuthentication.SetAuthCookie(user.UserName, true),其实SetAuthCookie里面的实现逻辑跟上面实现大同小异,只是我比较喜欢手动创建可以更多的控制一些辅助信息而已。在以上代码片段中,我着重想介绍一下FormsAuthentication.Encrypt(ticket)加密方法,因为它涉及到了Forms认证的安全机制,也好让各位朋友大概了解Forms认证到底安全不安全。FormsAuthentication该对象位于System.Web.Security名称空间下面,主要作用是安全相关辅助工具类,比如加解密等。
1.在默认情况下,ASPNETFORMS认证模块针对Ticker的加密Key是由ASPNET随机生成,并存储在本地安全机构LSA中。我们可以通过一下代码片段验证这一逻辑。

 private CryptographicKey GenerateCryptographicKey(string configAttributeName, string configAttributeValue, int autogenKeyOffset, int autogenKeyCount, string errorResourceString)
{
// 其他代码
bool flag1 = false;
bool flag2 = false;
bool flag3 = false;
if (configAttributeValue != null)
{
string str1 = configAttributeValue;
char[] chArray = new char[]{ ',' };
foreach (string str2 in str1.Split(chArray))
{
if (!(str2 == "AutoGenerate"))
{
if (!(str2 == "IsolateApps"))
{
if (!(str2 == "IsolateByAppId"))
flag3 = true;
}
else
flag2 = true;
}
else
flag1 = true;
}
}
if (flag2)
MachineKeyMasterKeyProvider.AddSpecificPurposeString((IList<string>) stringList, "IsolateApps", this.ApplicationName);
if (flag3)
MachineKeyMasterKeyProvider.AddSpecificPurposeString((IList<string>) stringList, "IsolateByAppId", this.ApplicationId);
}

以上代码片段逻辑也比较简单,自己体会吧。
2.手动指定machineKey配置节点,该配置节在web.config文件里面,其中包括可支持的加密算法,加密算法支持DES,3DES,AES等。具体代码我就不贴了,我们跟踪其实现原理意在了解Forms认证其安全性。
3.通过以上两点介绍,我个人认为Forms认证相对来说很安全。
Forms认证
下面我们看看Forms的实现原理。
ASPNET的Forms认证发生在ASPNET管道的FormsAuthenticationModule对象里面,在该对象里面的Init方法里面绑定了认证事件OnEnter,具体的认证实现是OnEnter里面调用的OnAuthenticate方法。我们来看下代码。

 private void OnAuthenticate(FormsAuthenticationEventArgs e)
{
// 其他代码
bool cookielessTicket = false;
// 从请求cookie里面抽取ticker票据信息
FormsAuthenticationTicket ticketFromCookie = FormsAuthenticationModule.ExtractTicketFromCookie(e.Context, FormsAuthentication.FormsCookieName, out cookielessTicket);
// 过期或者为null直接返回
if (ticketFromCookie == null || ticketFromCookie.Expired)
return;
FormsAuthenticationTicket ticket = ticketFromCookie;
// 如果启用滑动过期,更新过期时间
if (FormsAuthentication.SlidingExpiration)
ticket = FormsAuthentication.RenewTicketIfOld(ticketFromCookie);
e.Context.SetPrincipalNoDemand((IPrincipal) new GenericPrincipal((IIdentity) new FormsIdentity(ticket), new string[]));
if (!cookielessTicket && !ticket.CookiePath.Equals("/"))
{
cookie = e.Context.Request.Cookies[FormsAuthentication.FormsCookieName];
if (cookie != null)
cookie.Path = ticket.CookiePath;
}
if (ticket == ticketFromCookie)
return;
if (cookielessTicket && ticket.CookiePath != "/" && ticket.CookiePath.Length > )
ticket = FormsAuthenticationTicket.FromUtc(ticket.Version, ticket.Name, ticket.IssueDateUtc, ticket.ExpirationUtc, ticket.IsPersistent, ticket.UserData, "/");
string cookieValue = FormsAuthentication.Encrypt(ticket, !cookielessTicket); if (cookielessTicket)
{
e.Context.CookielessHelper.SetCookieValue('F', cookieValue);
e.Context.Response.Redirect(e.Context.Request.RawUrl);
}
else
{
if (cookie != null)
cookie = e.Context.Request.Cookies[FormsAuthentication.FormsCookieName];
if (cookie == null)
{
cookie = new HttpCookie(FormsAuthentication.FormsCookieName, cookieValue);
cookie.Path = ticket.CookiePath;
}
if (ticket.IsPersistent)
cookie.Expires = ticket.Expiration;
cookie.Value = cookieValue;
cookie.Secure = FormsAuthentication.RequireSSL;
cookie.HttpOnly = true;
if (FormsAuthentication.CookieDomain != null)
cookie.Domain = FormsAuthentication.CookieDomain;
cookie.SameSite = FormsAuthentication.CookieSameSite;
e.Context.Response.Cookies.Remove(cookie.Name);
e.Context.Response.Cookies.Add(cookie);
}
}

以上代码片段反映了Forms认证具体逻辑,逻辑比较简单,我也大概做了一些注释,以上就是ASPNET在MVC5.x之前ASPNETForms认证的实现。接下来我们对ASPNET5.X之前的版本基于Forms认证做个简单的总结。
1.用户在未登录的情况下,访问我们受保护的资源。
2.FormsAuthenticationModule模块验证用户的合法性,主要是生成Identity对象和设置IsAuthenticated属性。
3.如果未登录则endrequest阶段跳转到web.config配置的登录页或者硬编码指定的登录页。
4.用户登录。
5.匹配用户名&密码,如果合法,生成ticker票据和cookie并写入response。
6.访问受保护的资源(授权部分)。
7.FormsAuthenticationModule模块验证用户的合法性。
8.如果为以认证用户IsAuthenticated=true,授权访问相应的资源。
后续的每次请求也是6,7,8循环。
针对Forms认证就此告一段落,下面我们接着介绍MVC5的常规认证方式。
MVC5Cookies认证方式
为什么我要把MVC5的认证方式单独做一个小结讲解呢?它有什么特别之处吗?没错,ASPNETMVC5引入了新的设计理念OWin,我个人的理解是,解耦webserver容器IIS和模块化。同时NET4.5也引入了ASPNET.Identity,Identity主要是提供帮助我们管理用户、角色以及存储,当然Identity相较Membership强大多了。对于OWin和Identity我在这里不做详细介绍,自己可以去搜一些帖子看或者查看官方文档。OWin在WebServers与ASPNETWebApplication之间定义了一套标准接口,其官方的开源实现是Katana这个开源项目,我们今天要介绍的MVC5的认证就是基于Katana这个开源项目的CookieAuthenticationMiddleware中间件实现的,在介绍CookieAuthenticationMiddleware中间件之前,我想简单罗列一下MVC5的cookies认证(你也可以认为是Katana实现的新的Forms认证)和我们早期使用的Forms认证做个简单的对比。
相同点:1.基于cookie认证 2.支持滑动过期策略 3.实现令牌保护 4.重定向。
不同点:Identity结合Owin实现了声明认证Claims-based。
以上是个人的一点理解,下面我们具体看看认证中间件的实现,CookieAuthenticationMiddleware的定义。

 public class CookieAuthenticationMiddleware : AuthenticationMiddleware<CookieAuthenticationOptions>
{
// 其他成员
public CookieAuthenticationMiddleware(OwinMiddleware next, IAppBuilder app, CookieAuthenticationOptions options)
: base(next, options)
{
}
// 创建具体的AuthenticationHandler
protected override AuthenticationHandler<CookieAuthenticationOptions> CreateHandler()
{
return new CookieAuthenticationHandler(_logger);
}
}

CookieAuthenticationMiddleware里面就一个方法成员,通过CreateHandler方法创建了具体的CookieAuthenticationHandler对象,我们的认证核心实现就发生在这个Handler里面。接下来我们看看CookieAuthenticationHandler对象的定义。

 internal class CookieAuthenticationHandler : AuthenticationHandler<CookieAuthenticationOptions>
{
// 其他成员
private const string HeaderNameCacheControl = "Cache-Control";
private const string HeaderNamePragma = "Pragma";
private const string HeaderNameExpires = "Expires";
private const string HeaderValueNoCache = "no-cache";
private const string HeaderValueMinusOne = "-1";
private const string SessionIdClaim = "Microsoft.Owin.Security.Cookies-SessionId"; private bool _shouldRenew;
private DateTimeOffset _renewIssuedUtc;
private DateTimeOffset _renewExpiresUtc;
private string _sessionKey; protected override async Task<AuthenticationTicket> AuthenticateCoreAsync() protected override async Task ApplyResponseGrantAsync() protected override Task ApplyResponseChallengeAsync()
}

从CookieAuthenticationHandler对象的定义来看,其实也能看出一二,主要是针对cookie的相关操作,在该对象成员里面我们需要了解一下其中的三个方法。
1.AuthenticateCoreAsync,代码我就不贴了,有兴趣的朋友可以自己查看Katana开源项目的源代码。该方法内部大概实现思路是:从IOWinContext对象获取cookie,如果对owin不怎么熟悉的话,这个context你可以把它理解为我们之前熟悉的HttpContext,然后通过解密出来的cookie字符串构造ClaimsIdentity对象并添加到OwinContext对象Request.User,最后返回AuthenticationTicket对象,该对象包装的就是当前用户信息以及相关辅助信息。
2.ApplyResponseGrantAsync,设置、更新或者删除cookie并写入response。
3.ApplyResponseChallengeAsync,授权失败,发生重定向。

 public class AuthenticationTicket
{
public AuthenticationTicket(ClaimsIdentity identity, AuthenticationProperties properties)
{
Identity = identity;
Properties = properties ?? new AuthenticationProperties();
}
// 用户信息
public ClaimsIdentity Identity { get; private set; }
// 辅助信息,比如会话、过期等
public AuthenticationProperties Properties { get; private set; }
}

下面我们一起看看在我们开发过程中的应用以及内部实现
Startup是Katana开源项目引入的一种新的模块初始化方式,其实也没什么特别的,就是相关中间件的注册以及一些默认上下文对象的初始化操作。下面我们具体看代码,我们的MVC5新的认证方式在Startup里面如何注册的。

 public partial class Startup
{
public void ConfigureAuth(IAppBuilder app)
{
// 其他代码
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
LoginPath = new PathString("/Account/Login"),
Provider = new CookieAuthenticationProvider
{ }
});
}
}

注册逻辑很简单,通过IAppBuilder的扩展方法UseCookieAuthentication实现,接下来我们看看UseCookieAuthentication扩展方法的内部实现。

 public static IAppBuilder UseCookieAuthentication(this IAppBuilder app, CookieAuthenticationOptions options, PipelineStage stage)
{
if (app == null)
{ }
// 注册
app.Use(typeof(CookieAuthenticationMiddleware), app, options);
// 加入owin管道
app.UseStageMarker(stage);
return app;
}

整个注册逻辑就这么几行代码,相关方法都有注释。最后在程序初始化过程中通过Build方法完成Owin管道所有中间件的初始化工作。接下来我们看看具体的登录实现。

 public async Task<ActionResult> Login(LoginModel model,string returnUrl)
{
// 其他代码
if (ModelState.IsValid)
{
AppUser user = await UserManager.FindAsync(model.Name, model.Password);
if (user==null)
{
ModelState.AddModelError("","无效的用户名或密码");
}
else
{
var claimsIdentity =
await UserManager.CreateIdentityAsync(user, DefaultAuthenticationTypes.ApplicationCookie);
AuthManager.SignIn(new AuthenticationProperties {IsPersistent = false}, claimsIdentity);
return Redirect(returnUrl);
}
} return View(model);
}

通过以上代码片段就完成了我们系统的登录操作,在以上Login方法里面,我们需要注意这么几个方法。
1.FindAsync主要是通过Identity实现用户名和密码的匹配。
2.CreateIdentityAsync主要是创建ClaimsIdentity对象,该对象后续会写入cookie。
3.SignIn包装CreateIdentity方法创建的ClaimsIdentity以及ClaimsPrincipal对象,为cookie写入Response提供相关认证信息,只有在设置cookie阶段才会写入response。
接下来我们针对Katana里面的cookie认证做个简单的总结。
1.用户在未登录的情况下,访问我们受保护的资源。
2.CookieAuthenticationMiddleware中间件验证用户的合法性。
3.用户登录。
4.匹配用户名&密码,如果合法,包装相关认证信息。
5.创建\更新cookie写入response。
6.访问受保护的资源。
7.CookieAuthenticationMiddleware中间件解密cookie验证用户认证信息。
8.如果为以认证用户,授权访问相应的资源。
后续的每次请求也是6,7,8循环。
以上MVC5新的Cookies认证方式就此告一段落,下面我们接着介绍ASPNET.Identity三方认证。
三方认证
在我们介绍三方认证之前,我们不妨先来了解一下什么是Claim,大家把它翻译成声明,我也就这么跟着叫把。Claim所描述的是一个用户单一的某个信息,比如用户名,只有多个Claim组合才能描述一个完整的用户ClaimsIdentity对象。个人理解这是一种通用的信息存储结构,一种规范,可以很方便的基于用户数据信息驱动认证和授权并且提供独立服务,各自都不需要关心自己的实现。在我们传统的认证windows或者forms认证方式中,每个系统都有自己认证方式、授权和用户数据信息,如果是几年以前,可能没有什么问题,但是在如今飞速发展的互联网时代,就显的有很大的局限性、扩展性以及安全性。接下来我们要介绍的就是MVC5基于ASPNET.Identity结合Katana实现的三方认证,也就是我们上面说的基于Claims-based实现第三方认证,这里我们以google认证为例,由于网络问题这里我们以木宛城主大拿的实例代码做示例,我会结合实例代码分析内部实现。
首先我们需要添加google服务认证中间件。

 app.UseGoogleAuthentication(new GoogleOAuth2AuthenticationOptions()
{
// 以下为客户端凭据,可以通过google认证服务注册
ClientId = "",
ClientSecret = "",
});

其二我们需要设计实现登录逻辑,通常情况下我们在登录论坛的时候,旁边可能会有基于QQ登录或者别的三方认证提供商。

 public ActionResult GoogleLogin(string returnUrl)
{ // 创建AuthenticationProperties对象,我们可以理解为认证复制信息字典
var properties = new AuthenticationProperties
{
RedirectUri = Url.Action("GoogleLoginCallback",
new { returnUrl = returnUrl })
};
// 初始化google认证相关辅助信息
HttpContext.GetOwinContext().Authentication.Challenge(properties, "Google");
// 返回401
return new HttpUnauthorizedResult();
}

以上代码比较简单,我也做了相应的注释,其逻辑是初始化google认证的一些辅助信息,然后返回401状态码,继而重定向到google登录页。下面我们看看登录成功之后的代码逻辑。

 public async Task<ActionResult> GoogleLoginCallback(string returnUrl)
{
// 从google认证服务获取claims
ExternalLoginInfo loginInfo = await AuthManager.GetExternalLoginInfoAsync();
// 检查该用户是否首次登录系统
AppUser user = await UserManager.FindAsync(loginInfo.Login);
if (user == null)
{
user = new AppUser
{
Email = loginInfo.Email,
UserName = loginInfo.DefaultUserName,
City = Cities.Shanghai,
Country = Countries.China
};
// 持久化用户数据
IdentityResult result = await UserManager.CreateAsync(user);
// 缓存
result = await UserManager.AddLoginAsync(user.Id, loginInfo.Login);
}
ClaimsIdentity ident = await UserManager.CreateIdentityAsync(user,
DefaultAuthenticationTypes.ApplicationCookie);
ident.AddClaims(loginInfo.ExternalIdentity.Claims);
// 创建用户ClaimsIdentity对象
AuthManager.SignIn(new AuthenticationProperties
{
IsPersistent = false
}, ident);
return Redirect(returnUrl ?? "/");
}

以上就是三方认证的实现方式,下面我们通过Katana源码看看三方认证的实现原理。通过上面Katana的cookies认证,我们了解到认证中间件的认证逻辑是实现在相应的AuthenticationHandler里面,我们同样以google为例,去看看内部的实现。下面我们一起来上面注册的认证中间件GoogleOAuth2AuthenticationMiddleware的定义。

 public class GoogleOAuth2AuthenticationMiddleware : AuthenticationMiddleware<GoogleOAuth2AuthenticationOptions>
{
// 其他成员
public GoogleOAuth2AuthenticationMiddleware(
OwinMiddleware next,
IAppBuilder app,
GoogleOAuth2AuthenticationOptions options)
: base(next, options);
// 构建认证handler
protected override AuthenticationHandler<GoogleOAuth2AuthenticationOptions> CreateHandler()
{
return new GoogleOAuth2AuthenticationHandler(_httpClient, _logger);
}
// 构建httpclienthandler
private static HttpMessageHandler ResolveHttpMessageHandler(GoogleOAuth2AuthenticationOptions options);
}

根据以上代码片段我们了解到,GoogleOAuth2AuthenticationMiddleware中间件似乎比我们常规的cookies认证多了一个方法ResolveHttpMessageHandler,其实这个方法没有别的套路,就是辅助创建httpclient对象,完成http请求而已,在handler的认证逻辑里面需要获取googletoken,就是通过它来获取的。
第二个方法CreateHandler返回的GoogleOAuth2AuthenticationHandler对象就是我们接下来要重点讨论的对象。

 internal class GoogleOAuth2AuthenticationHandler : AuthenticationHandler<GoogleOAuth2AuthenticationOptions>
{
private const string TokenEndpoint = "https://accounts.google.com/o/oauth2/token";
private const string UserInfoEndpoint = "https://www.googleapis.com/plus/v1/people/me";
private const string AuthorizeEndpoint = "https://accounts.google.com/o/oauth2/auth"; private readonly ILogger _logger;
private readonly HttpClient _httpClient; public GoogleOAuth2AuthenticationHandler(HttpClient httpClient, ILogger logger)
{
_httpClient = httpClient;
_logger = logger;
}
// 通过httpclient访问google认证服务器获取token,根据token数据包装Claim
protected override async Task<AuthenticationTicket> AuthenticateCoreAsync();
// 如果未认证,401授权失败发生重定向
protected override Task ApplyResponseChallengeAsync(); public override async Task<bool> InvokeAsync()
{
return await InvokeReplyPathAsync();
}
// 调用signin,保存用户信息
private async Task<bool> InvokeReplyPathAsync();
}

代码比较长,我把具体实现删掉了,实现逻辑我注释到了方法上面,有兴趣的朋友可以自己多看看源码。以上就是NET平台上面一些主流的认证方式和实现原理。接下来我们继续介绍ASPNETCORE的认证。

ASPNETCORE认证
熟悉微软web平台认证授权体系的朋友应该知道,不管是早期的Forms还是Katana的cookies甚至是我接下来要介绍的ASPNETCORE基于cookies认证,其实整体的设计逻辑大致都差不多,只是具体实现上的区别,尤其是OWin的设计理念,当然现在我们几乎已经模糊了OWin的慨念,但是在ASPNETCORE平台上到处都有它的缩影。下面我们一起来看看ASPNETCOREMVC的认证机制。
在这里,整个认证逻辑我就直接用一张图展示:

画图工具是网上在线编辑的,画的不好,别见怪。下面我简单解释一下认证授权流程图,以cookies认证为例。
1.认证中间件调用CookieAuthenticationHandler实现认证,如果认证成功设置HttpContext.Use对象。
2.在执行controller中的action之前,执行授权filter,如果有设置授权filter特性。
3.如果controller或者action上没有授权filter,直接执行action,呈现view。
4.如果有定义授权filter特性,授权过滤器再次检查用户是否认证,并且合并Claim,因为可以指定多个认证scheme,认证阶段使用的是默认的sheme。
5.认证失败,授权filter设置context.Result为Challenge,在后续cookie认证中间件会发生重定向到login页面。
6.认证成功,授权失败,授权filter设置context.Result为Forbid,在后续cookie认证中间件会发生重定向到权限不足页面。
7.认证、授权都通过,最后显示view。
以上就是ASPNETCOREMVC认证授权的主要执行逻辑。接下来我们一起看看,基于COREMVC的cookies认证的应用以及内部实现。
熟悉ASPNETCORE平台开发的朋友应该知道,基础功能模块的配置初始化,一般分为两部曲,注册服务、配置中间件。当然这少不了NETCORE内置DI容器的功劳,我们将要介绍的认证系统也不例外。下面我们具体看看认证系统的配置,通过Startup类型配置,关于startup的提供机制可以看看我上一篇博客,有详细介绍。
第一部曲服务配置

 public static void AddAuthentication(this IServiceCollection services)
{ // 其他代码
var authenticationBuilder = services.AddAuthentication(options =>
{
options.DefaultChallengeScheme = AuthenticationDefaults.AuthenticationScheme;
options.DefaultScheme = AuthenticationDefaults.AuthenticationScheme;
options.DefaultSignInScheme = AuthenticationDefaults.ExternalAuthenticationScheme;
})
.AddCookie(AuthenticationDefaults.AuthenticationScheme, options =>
{
options.Cookie.Name = $"{CookieDefaults.Prefix}{NopCookieDefaults.AuthenticationCookie}";
options.Cookie.HttpOnly = true;
options.LoginPath = AuthenticationDefaults.LoginPath;
options.AccessDeniedPath = AuthenticationDefaults.AccessDeniedPath;
})
.AddCookie(AuthenticationDefaults.ExternalAuthenticationScheme, options =>
{
options.Cookie.Name = $"{CookieDefaults.Prefix}{CookieDefaults.ExternalAuthenticationCookie}";
options.Cookie.HttpOnly = true;
options.LoginPath = AuthenticationDefaults.LoginPath;
options.AccessDeniedPath = AuthenticationDefaults.AccessDeniedPath;
});
}

以上代码片段就完成了cookies认证的所需服务注册。其实际就是注册cookies认证所需的基础对象和辅助配置信息到DI容器,以便中间件可以通过DI容器方便获取。AddAuthentication扩展方法,主要是注册认证系统所需基础对象。AddCookie扩展方法主要是注册具体cookie认证Handler对象以及通过options模式配置辅助信息。
第二部曲中间件注册

 public static void UseAuthentication(this IApplicationBuilder application)
{
// 其他代码
application.UseMiddleware<AuthenticationMiddleware>();
}

认证中间件的注册就这么一句代码,实际就是ASPNETCORE请求管道添加认证中间件,最后通过Build初始化到这个请求管道,后续所有的请求都会通过这个认证中间件的invoke方法处理,然后传递下一个中间件,关于中间件的原理也可以看我上一篇帖子。认证系统的配置我们已经准备完成,下面我们看看系统登录。
登录

   [HttpPost]
public virtual IActionResult Login(LoginModel model, string returnUrl, bool captchaValid)
{ // 其他代码
if (ModelState.IsValid)
{
var loginResult = _userService.ValidateUser(model.Username, model.Password);
switch (loginResult)
{
case LoginResults.Successful:
{
var user = _userService.GetUserByUserName(model.Username); _authenticationService.SignIn(user, model.RememberMe); return Redirect(returnUrl);
}
}
} return View(model);
}

以上登录代码片段比较简单,主要完成两个动作,1.收集用户输入的用户名&密码等信息,然后通过我们系统的存储介质,校验用户名&密码的合法性。2.登录到我们的认证系统,实现我们核心登录逻辑是SignIn方法里面。下面我们继续看看SignIn方法的具体实现。

 public virtual async void SignIn(User user, bool isPersistent)
{
// 其他代码
// 创建身份信息集合
var claims = new List<Claim>(); if (!string.IsNullOrEmpty(user.Username))
claims.Add(new Claim(ClaimTypes.Name, user.Username, ClaimValueTypes.String, AuthenticationDefaults.ClaimsIssuer)); if (!string.IsNullOrEmpty(user.Email))
claims.Add(new Claim(ClaimTypes.Email, user.Email, ClaimValueTypes.Email, AuthenticationDefaults.ClaimsIssuer)); var userIdentity = new ClaimsIdentity(claims, AuthenticationDefaults.AuthenticationScheme);
var userPrincipal = new ClaimsPrincipal(userIdentity);
// 辅助信息
var authenticationProperties = new AuthenticationProperties
{
IsPersistent = isPersistent,
IssuedUtc = DateTime.UtcNow
};
// 创建cookie ticket,以备写入response输出到客户端
await _httpContextAccessor.HttpContext.SignInAsync(AuthenticationDefaults.AuthenticationScheme, userPrincipal, authenticationProperties);
}

以上代码片段就完成了我们认证系统的登录。大致逻辑是构建身份声明信息,调用HttpContext的SignInAsync方法创建ticket,在endrequest阶段创建cookie写入response。以上就是我们基于ASPNETCORE平台开发web应用对于认证的真实应用。接下来我们重点看看平台的内部实现。
Cookies认证内部实现
我们还是从服务注册开始吧,毕竟它是完成认证系统的基石。我们把视线转移到上面的AddAuthentication方法,注册服务,我们看看它到底为我们的认证系统注册了哪些基础服务,看NETCORE源代码。

 public static AuthenticationBuilder AddAuthentication(this IServiceCollection services)
{
// 其他代码
services.AddAuthenticationCore();
services.AddDataProtection();
services.AddWebEncoders();
services.TryAddSingleton<ISystemClock, SystemClock>();
return new AuthenticationBuilder(services);
}

从以上代码片段了解到,我们的认证服务注册是在平台AddAuthenticationCore方法里面完成的。我们一起看看AddAuthenticationCore方法的实现。

 public static IServiceCollection AddAuthenticationCore(this IServiceCollection services)
{
services.TryAddScoped<IAuthenticationService, AuthenticationService>();
services.TryAddSingleton<IClaimsTransformation, NoopClaimsTransformation>(); // Can be replaced with scoped ones that use DbContext
services.TryAddScoped<IAuthenticationHandlerProvider, AuthenticationHandlerProvider>();
services.TryAddSingleton<IAuthenticationSchemeProvider, AuthenticationSchemeProvider>();
return services;
}

AddAuthenticationCore方法里面主要注册了我们NETCORE认证系统的三个基础对象,你可以把它们理解为黑帮的一个老大两个堂主,由它们吩咐下面的小弟完成任务,言归正传这三个对象也是完成我们NETCORE平台认证的三剑客,通过Provider模式实现,下面我们一个个来介绍,我们先看看IAuthenticationService接口的定义。

 public interface IAuthenticationService
{
Task<AuthenticateResult> AuthenticateAsync(HttpContext context, string scheme); Task ChallengeAsync(HttpContext context, string scheme, AuthenticationProperties properties); Task ForbidAsync(HttpContext context, string scheme, AuthenticationProperties properties); Task SignInAsync(HttpContext context, string scheme, ClaimsPrincipal principal, AuthenticationProperties properties); Task SignOutAsync(HttpContext context, string scheme, AuthenticationProperties properties);
}

IAuthenticationService接口定义了5个方法成员,它本身不实现任何认证逻辑,只是为IAuthenticationSchemeProvider 和 IAuthenticationHandlerProvider这两个Provider实现了封装,提供认证服务的统一接口。下面我大概解释一下这个5个方法在认证服务中的作用。
1.SignInAsync 登录操作,如果登录成功,生成加密ticket,用来标识用户的身份。
2.SignOutAsync 退出登录,清除Coookie等。
3.AuthenticateAsync 解密cookie,获取ticket并验证,最后返回一个 AuthenticateResult 对象,表示用户的身份。
4.ChallengeAsync 未认证,返回 401 状态码。
5.ForbidAsync 权限不足,返回 403 状态码。
下面我们一起看看它的唯一默认实现类AuthenticationService。

 public class AuthenticationService : IAuthenticationService
{ // 其他成员
public AuthenticationService(IAuthenticationSchemeProvider schemes, IAuthenticationHandlerProvider handlers, IClaimsTransformation transform); public IAuthenticationSchemeProvider Schemes { get; } public IAuthenticationHandlerProvider Handlers { get; } public IClaimsTransformation Transform { get; } public virtual async Task<AuthenticateResult> AuthenticateAsync(HttpContext context, string scheme); public virtual async Task ChallengeAsync(HttpContext context, string scheme, AuthenticationProperties properties)
{
if (scheme == null)
{
var defaultChallengeScheme = await Schemes.GetDefaultChallengeSchemeAsync();
scheme = defaultChallengeScheme?.Name;
if (scheme == null)
{
throw new InvalidOperationException($"No authenticationScheme was specified, and there was no DefaultChallengeScheme found.");
}
} var handler = await Handlers.GetHandlerAsync(context, scheme);
if (handler == null)
{
throw await CreateMissingHandlerException(scheme);
} await handler.ChallengeAsync(properties);
} public virtual async Task ForbidAsync(HttpContext context, string scheme, AuthenticationProperties properties); public virtual async Task SignInAsync(HttpContext context, string scheme, ClaimsPrincipal principal, AuthenticationProperties properties); public virtual async Task SignOutAsync(HttpContext context, string scheme, AuthenticationProperties properties);
}

代码比较多,我删掉了大部分,其实现逻辑都差不多。我们以ChallengeAsync方法为例,先获取相应的scheme,然后获取对应的Handler,最后执行Handler的同名方法。也就说明,真正的认证逻辑是在Handler里面完成的。从AuthenticationService的定义了解到,AuthenticationService的创建是基于Handlers和schemes创建的,下面我们看看认证的第二个基础对象IAuthenticationSchemeProvider。

 public interface IAuthenticationSchemeProvider
{
Task<IEnumerable<AuthenticationScheme>> GetAllSchemesAsync(); Task<AuthenticationScheme> GetSchemeAsync(string name); Task<AuthenticationScheme> GetDefaultAuthenticateSchemeAsync(); Task<AuthenticationScheme> GetDefaultChallengeSchemeAsync(); Task<AuthenticationScheme> GetDefaultForbidSchemeAsync(); Task<AuthenticationScheme> GetDefaultSignInSchemeAsync(); Task<AuthenticationScheme> GetDefaultSignOutSchemeAsync(); void AddScheme(AuthenticationScheme scheme); void RemoveScheme(string name); Task<IEnumerable<AuthenticationScheme>> GetRequestHandlerSchemesAsync();
}

scheme其实际就是提供认证方案标识,我们知道,NETCORE的认证系统所支持的认证方案非常丰富,比如openid、bearer、cookie等等。下面我们一起看看它的默认实现AuthenticationSchemeProvider对象。

 public class AuthenticationSchemeProvider : IAuthenticationSchemeProvider
{
public AuthenticationSchemeProvider(IOptions<AuthenticationOptions> options)
: this(options, new Dictionary<string, AuthenticationScheme>(StringComparer.Ordinal))
{
} protected AuthenticationSchemeProvider(IOptions<AuthenticationOptions> options, IDictionary<string, AuthenticationScheme> schemes)
{
_options = options.Value; _schemes = schemes ?? throw new ArgumentNullException(nameof(schemes));
_requestHandlers = new List<AuthenticationScheme>(); foreach (var builder in _options.Schemes)
{
var scheme = builder.Build();
AddScheme(scheme);
}
} private readonly AuthenticationOptions _options;
private readonly object _lock = new object();
private readonly IDictionary<string, AuthenticationScheme> _schemes;
private readonly List<AuthenticationScheme> _requestHandlers;
private IEnumerable<AuthenticationScheme> _schemesCopy = Array.Empty<AuthenticationScheme>();
private IEnumerable<AuthenticationScheme> _requestHandlersCopy = Array.Empty<AuthenticationScheme>(); private Task<AuthenticationScheme> GetDefaultSchemeAsync()
=> _options.DefaultScheme != null
? GetSchemeAsync(_options.DefaultScheme)
: Task.FromResult<AuthenticationScheme>(null); public virtual Task<AuthenticationScheme> GetDefaultAuthenticateSchemeAsync()
=> _options.DefaultAuthenticateScheme != null
? GetSchemeAsync(_options.DefaultAuthenticateScheme)
: GetDefaultSchemeAsync(); public virtual Task<AuthenticationScheme> GetDefaultChallengeSchemeAsync()
=> _options.DefaultChallengeScheme != null
? GetSchemeAsync(_options.DefaultChallengeScheme)
: GetDefaultSchemeAsync(); public virtual Task<AuthenticationScheme> GetDefaultForbidSchemeAsync()
=> _options.DefaultForbidScheme != null
? GetSchemeAsync(_options.DefaultForbidScheme)
: GetDefaultChallengeSchemeAsync(); public virtual Task<AuthenticationScheme> GetDefaultSignInSchemeAsync()

if (_schemes.ContainsKey(scheme.Name))
{
throw new InvalidOperationException("Scheme already exists: " + scheme.Name);
}
lock (_lock)
{
if (_schemes.ContainsKey(scheme.Name))
{
throw new InvalidOperationException("Scheme already exists: " + scheme.Name);
}
if (typeof(IAuthenticationRequestHandler).IsAssignableFrom(scheme.HandlerType))
{
_requestHandlers.Add(scheme);
_requestHandlersCopy = _requestHandlers.ToArray();
}
_schemes[scheme.Name] = scheme;
_schemesCopy = _schemes.Values.ToArray();
}
} public virtual void RemoveScheme(string name); public virtual Task<IEnumerable<AuthenticationScheme>> GetAllSchemesAsync()
=> Task.FromResult(_schemesCopy);
}

从AuthenticationSchemeProvider的默认实现来看,它主要是提供scheme管理。从AuthenticationSchemeProvider构造器的定义来看,它的初始化是由我们注册服务时所提供的options配置对象提供,其最终初始化体现在AddScheme方法上,也就是对所有注册的scheme添加集合,所有scheme最终体现为一个AuthenticationScheme对象,下面我们看看它的定义。

 public class AuthenticationScheme
{
public AuthenticationScheme(string name, string displayName, Type handlerType)
{
// 其他代码
if (!typeof(IAuthenticationHandler).IsAssignableFrom(handlerType))
{
throw new ArgumentException("handlerType must implement
IAuthenticationHandler.");
} Name = name;
HandlerType = handlerType;
DisplayName = displayName;
} public string Name { get; } public string DisplayName { get; } public Type HandlerType { get; }
}

每一个scheme里面都包含了对应的Handler,同时派生自IAuthenticationHandler。这个handler就是后续真正处理我们的认证实现。下面我们一起看看认证基石的第三个对象IAuthenticationHandlerProvider的定义。

 public interface IAuthenticationHandlerProvider
{
Task<IAuthenticationHandler> GetHandlerAsync(HttpContext context, string authenticationScheme);
}

这个接口的定义很简单,就一个成员,GetHandlerAsync方法,顾名思义就是获取authenticationScheme对应的Handler,我们看看IAuthenticationHandlerProvider的默认实现。

 public class AuthenticationHandlerProvider : IAuthenticationHandlerProvider
{
public AuthenticationHandlerProvider(IAuthenticationSchemeProvider schemes)
{
Schemes = schemes;
} public IAuthenticationSchemeProvider Schemes { get; } private Dictionary<string, IAuthenticationHandler> _handlerMap = new Dictionary<string, IAuthenticationHandler>(StringComparer.Ordinal); public async Task<IAuthenticationHandler> GetHandlerAsync(HttpContext context, string authenticationScheme)
{
if (_handlerMap.ContainsKey(authenticationScheme))
{
return _handlerMap[authenticationScheme];
} var scheme = await Schemes.GetSchemeAsync(authenticationScheme);
if (scheme == null)
{
return null;
}
var handler = (context.RequestServices.GetService(scheme.HandlerType) ??
ActivatorUtilities.CreateInstance(context.RequestServices, scheme.HandlerType))
as IAuthenticationHandler;
if (handler != null)
{
await handler.InitializeAsync(scheme, context);
_handlerMap[authenticationScheme] = handler;
}
return handler;
}
}

GetHandlerAsync方法的实现逻辑也比较简单,首先通过_handlerMap字典根据scheme名称获取,一般首次获取,都是null。然后通过schemeprovide获取对应的scheme,通过上面分析我们知道,scheme体现为一个AuthenticationScheme对象,里面包含了handlertype。最后创建这个handler,创建handler有两种情况,第一种从DI容器获取,第二种情况反射创建,最终返回的是有如下定义的IAuthenticationHandler接口。

 public interface IAuthenticationHandler
{
Task InitializeAsync(AuthenticationScheme scheme, HttpContext context); Task<AuthenticateResult> AuthenticateAsync(); Task ChallengeAsync(AuthenticationProperties properties); Task ForbidAsync(AuthenticationProperties properties);
}

该接口就是实打实干实事的,我们的认证逻辑就是通过该handler实现的。AuthenticateAsync方法就是我们的认证入口,其返回类型是一个AuthenticateResult类型,也就是我们的认证结果,接下来我们看看它的定义。

 public class AuthenticateResult
{
protected AuthenticateResult() { } public bool Succeeded => Ticket != null; public AuthenticationTicket Ticket { get; protected set; } public ClaimsPrincipal Principal => Ticket?.Principal; public AuthenticationProperties Properties { get; protected set; } public Exception Failure { get; protected set; } public bool None { get; protected set; } public static AuthenticateResult Success(AuthenticationTicket ticket)
{
if (ticket == null)
{
throw new ArgumentNullException(nameof(ticket));
}
return new AuthenticateResult() { Ticket = ticket, Properties = ticket.Properties };
} public static AuthenticateResult NoResult()
{
return new AuthenticateResult() { None = true };
} public static AuthenticateResult Fail(Exception failure)
{
return new AuthenticateResult() { Failure = failure };
} public static AuthenticateResult Fail(Exception failure, AuthenticationProperties properties)
{
return new AuthenticateResult() { Failure = failure, Properties = properties };
} public static AuthenticateResult Fail(string failureMessage)
=> Fail(new Exception(failureMessage)); public static AuthenticateResult Fail(string failureMessage, AuthenticationProperties properties)
=> Fail(new Exception(failureMessage), properties);
}

如上代码,AuthenticateResult对象的定义逻辑很简单,就是包装认证结果信息,比如AuthenticationTicket,它主要定义了我们的基本认证信息,我们可以把它理解为一张认证后的票据信息。AuthenticationProperties类型它主要定义了我们认证相关的辅助信息,其中包括过期、重定向、持久等等信息。关于这两个类型的定义我就不贴代码了,其实现比较简单。兜兜转转终于到了我们的cooke认证实现类CookieAuthenticationHandler对象,下面我们一起看看它的定义。

 public class CookieAuthenticationHandler : SignInAuthenticationHandler<CookieAuthenticationOptions>
{
// 其他代码
public CookieAuthenticationHandler(IOptionsMonitor<CookieAuthenticationOptions> options, ILoggerFactory logger, UrlEncoder encoder, ISystemClock clock)
: base(options, logger, encoder, clock)
{ } protected override async Task<AuthenticateResult> HandleAuthenticateAsync(); protected virtual async Task FinishResponseAsync(); protected async override Task HandleSignInAsync(ClaimsPrincipal user, AuthenticationProperties properties); protected async override Task HandleSignOutAsync(AuthenticationProperties properties); protected override async Task HandleForbiddenAsync(AuthenticationProperties properties); protected override async Task HandleChallengeAsync(AuthenticationProperties properties);
}

我们暂且先不讨论CookieAuthenticationHandler认证实现逻辑,因为整个认证结构,有涉及多个Handler对象,我们还是一步一步按照这个层次结构来介绍吧,至少大家不会觉得突兀。从CookieAuthenticationHandler的定义来看,它并未直接实现IAuthenticationHandler,还是实现了有着如下定义的SignInAuthenticationHandler接口对象。

 public abstract class SignInAuthenticationHandler<TOptions> : SignOutAuthenticationHandler<TOptions>, IAuthenticationSignInHandler
where TOptions : AuthenticationSchemeOptions, new()
{
public SignInAuthenticationHandler(IOptionsMonitor<TOptions> options, ILoggerFactory logger, UrlEncoder encoder, ISystemClock clock) : base(options, logger, encoder, clock)
{ } public virtual Task SignInAsync(ClaimsPrincipal user, AuthenticationProperties properties)
{
var target = ResolveTarget(Options.ForwardSignIn);
return (target != null)
? Context.SignInAsync(target, user, properties)
: HandleSignInAsync(user, properties ?? new AuthenticationProperties());
} protected abstract Task HandleSignInAsync(ClaimsPrincipal user, AuthenticationProperties properties);
}

从该对象的定义来看,它就是负责处理登录相关处理的。其中还有SignOutAuthenticationHandler,处理逻辑类似,负责登出操作,可能有些朋友会觉得有点奇怪,为什么登入登出会单独定义成相关接口,个人理解,其一站在业务的角度,登入、登出和认证还是有一定的独立性,并非所有业务场景必须要先登录才能实现认证,而且认证更多关注的是过程,其二以适应更多认证方式,把登入登出抽象出来,使其扩展更方便。它们派生自抽象类AuthenticationHandler<TOptions>,下面我们看看它的定义。

 public abstract class AuthenticationHandler<TOptions> : IAuthenticationHandler where TOptions : AuthenticationSchemeOptions, new()
{
// 其他代码
protected AuthenticationHandler(IOptionsMonitor<TOptions> options, ILoggerFactory logger, UrlEncoder encoder, ISystemClock clock)
{
Logger = logger.CreateLogger(this.GetType().FullName);
UrlEncoder = encoder;
Clock = clock;
OptionsMonitor = options;
} public async Task InitializeAsync(AuthenticationScheme scheme, HttpContext context)
{
if (scheme == null)
{
throw new ArgumentNullException(nameof(scheme));
}
if (context == null)
{
throw new ArgumentNullException(nameof(context));
} Scheme = scheme;
Context = context; Options = OptionsMonitor.Get(Scheme.Name); await InitializeEventsAsync();
await InitializeHandlerAsync();
} protected virtual async Task InitializeEventsAsync()
{
Events = Options.Events;
if (Options.EventsType != null)
{
Events = Context.RequestServices.GetRequiredService(Options.EventsType);
}
Events = Events ?? await CreateEventsAsync();
} protected virtual Task<object> CreateEventsAsync() => Task.FromResult(new object()); protected virtual Task InitializeHandlerAsync() => Task.CompletedTask; protected string BuildRedirectUri(string targetPath)
=> Request.Scheme + "://" + Request.Host + OriginalPathBase + targetPath; protected virtual string ResolveTarget(string scheme)
{
var target = scheme ?? Options.ForwardDefaultSelector?.Invoke(Context) ?? Options.ForwardDefault; // Prevent self targetting
return string.Equals(target, Scheme.Name, StringComparison.Ordinal)
? null
: target;
} public async Task<AuthenticateResult> AuthenticateAsync()
{
var target = ResolveTarget(Options.ForwardAuthenticate);
if (target != null)
{
return await Context.AuthenticateAsync(target);
} var result = await HandleAuthenticateOnceAsync();
if (result?.Failure == null)
{
var ticket = result?.Ticket;
if (ticket?.Principal != null)
{
Logger.AuthenticationSchemeAuthenticated(Scheme.Name);
}
else
{
Logger.AuthenticationSchemeNotAuthenticated(Scheme.Name);
}
}
else
{
Logger.AuthenticationSchemeNotAuthenticatedWithFailure(Scheme.Name, result.Failure.Message);
}
return result;
} protected Task<AuthenticateResult> HandleAuthenticateOnceAsync()
{
if (_authenticateTask == null)
{
_authenticateTask = HandleAuthenticateAsync();
} return _authenticateTask;
} protected async Task<AuthenticateResult> HandleAuthenticateOnceSafeAsync()
{
try
{
return await HandleAuthenticateOnceAsync();
}
catch (Exception ex)
{
return AuthenticateResult.Fail(ex);
}
} protected abstract Task<AuthenticateResult> HandleAuthenticateAsync(); protected virtual Task HandleForbiddenAsync(AuthenticationProperties properties)
{
Response.StatusCode = ;
return Task.CompletedTask;
} protected virtual Task HandleChallengeAsync(AuthenticationProperties properties)
{
Response.StatusCode = ;
return Task.CompletedTask;
} public async Task ChallengeAsync(AuthenticationProperties properties)
{
var target = ResolveTarget(Options.ForwardChallenge);
if (target != null)
{
await Context.ChallengeAsync(target, properties);
return;
} properties = properties ?? new AuthenticationProperties();
await HandleChallengeAsync(properties);
Logger.AuthenticationSchemeChallenged(Scheme.Name);
} public async Task ForbidAsync(AuthenticationProperties properties)
{
var target = ResolveTarget(Options.ForwardForbid);
if (target != null)
{
await Context.ForbidAsync(target, properties);
return;
} properties = properties ?? new AuthenticationProperties();
await HandleForbiddenAsync(properties);
Logger.AuthenticationSchemeForbidden(Scheme.Name);
}
}

该抽象类直接实现了我们上面提到的认证接口IAuthenticationHandler,是NETCORE所有认证类的基类,并且提供相关默认实现。抽象方法HandleAuthenticateAsync就是我们认证处理的入口,也是认证的核心实现,由具体的认证实现类实现。该基类的其他方法,逻辑都比较简单,或者只提供默认实现就不再赘述,接下来我们围绕上面提到的cookie认证的核心实现类CookieAuthenticationHandler介绍其具体认证实现,在介绍其具体实现之前,我们来看看它是如何被创建的或者说被注入到我们的DI容器的,其实是通过Startup的ConfigureServices方法注册进来的,看代码。

 public static AuthenticationBuilder AddCookie(this AuthenticationBuilder builder, string authenticationScheme, string displayName, Action<CookieAuthenticationOptions> configureOptions)
{
builder.Services.TryAddEnumerable(ServiceDescriptor.Singleton<IPostConfigureOptions<CookieAuthenticationOptions>, PostConfigureCookieAuthenticationOptions>());
builder.Services.AddOptions<CookieAuthenticationOptions>(authenticationScheme).Validate(o => o.Cookie.Expiration == null, "Cookie.Expiration is ignored, use ExpireTimeSpan instead.");
return builder.AddScheme<CookieAuthenticationOptions, CookieAuthenticationHandler>(authenticationScheme, displayName, configureOptions);
}

通过CookieExtensions的扩展方法AddCookie方法注入进来的,有疑惑的朋友可以看看我在开始介绍NETCORE认证的开始部分就贴出了这段代码。接下来我们继续看认证核心部分。

 public class CookieAuthenticationHandler : SignInAuthenticationHandler<CookieAuthenticationOptions>
{
// 其他成员
public CookieAuthenticationHandler(IOptionsMonitor<CookieAuthenticationOptions> options, ILoggerFactory logger, UrlEncoder encoder, ISystemClock clock)
: base(options, logger, encoder, clock)
{ } protected new CookieAuthenticationEvents Events
{
get { return (CookieAuthenticationEvents)base.Events; }
set { base.Events = value; }
}
// 初始化handler,设置响应cookie回调
protected override Task InitializeHandlerAsync()
{
// Cookies needs to finish the response
Context.Response.OnStarting(FinishResponseAsync);
return Task.CompletedTask;
}
// cookie认证各个处理阶段,默认注册的事件
protected override Task<object> CreateEventsAsync() => Task.FromResult<object>(new CookieAuthenticationEvents());
// 获取ticket票据
private Task<AuthenticateResult> EnsureCookieTicket();
// 刷新票据
private void CheckForRefresh(AuthenticationTicket ticket); private void RequestRefresh(AuthenticationTicket ticket, ClaimsPrincipal replacedPrincipal = null);
// clone票据
private AuthenticationTicket CloneTicket(AuthenticationTicket ticket, ClaimsPrincipal replacedPrincipal); private async Task<AuthenticateResult> ReadCookieTicket();
// cookie认证
protected override async Task<AuthenticateResult> HandleAuthenticateAsync()
{
// 获取票据
var result = await EnsureCookieTicket();
if (!result.Succeeded)
{
return result;
}
// 用户信息验证,默认没有任何逻辑实现
var context = new CookieValidatePrincipalContext(Context, Scheme, Options, result.Ticket);
await Events.ValidatePrincipal(context); if (context.Principal == null)
{
return AuthenticateResult.Fail("No principal.");
}
// 更新ticket票据,一般在之前会更新用户信息
if (context.ShouldRenew)
{
RequestRefresh(result.Ticket, context.Principal);
}
// 认证成功,包装result返回
return AuthenticateResult.Success(new AuthenticationTicket(context.Principal, context.Properties, Scheme.Name));
}
// 写入response
protected virtual async Task FinishResponseAsync();
// 登录,
protected async override Task HandleSignInAsync(ClaimsPrincipal user, AuthenticationProperties properties)
{
if (user == null)
{
throw new ArgumentNullException(nameof(user));
}
// 获取配置信息
properties = properties ?? new AuthenticationProperties(); _signInCalled = true; // 初始化,比如sessionkey
await EnsureCookieTicket();
var cookieOptions = BuildCookieOptions();
// 创建cookiecontext,以备写入response
var signInContext = new CookieSigningInContext(
Context,
Scheme,
Options,
user,
properties,
cookieOptions);
// 设置认证辅助信息,比如过期时间等等。
DateTimeOffset issuedUtc;
if (signInContext.Properties.IssuedUtc.HasValue)
{
issuedUtc = signInContext.Properties.IssuedUtc.Value;
}
else
{
issuedUtc = Clock.UtcNow;
signInContext.Properties.IssuedUtc = issuedUtc;
} if (!signInContext.Properties.ExpiresUtc.HasValue)
{
signInContext.Properties.ExpiresUtc = issuedUtc.Add(Options.ExpireTimeSpan);
}
// 执行signin阶段处理事件,如果有重写,执行重写逻辑
await Events.SigningIn(signInContext);
// 是否持久化
if (signInContext.Properties.IsPersistent)
{
var expiresUtc = signInContext.Properties.ExpiresUtc ?? issuedUtc.Add(Options.ExpireTimeSpan);
signInContext.CookieOptions.Expires = expiresUtc.ToUniversalTime();
}
// 创建认证票据ticket
var ticket = new AuthenticationTicket(signInContext.Principal, signInContext.Properties, signInContext.Scheme.Name);
// 基于session逻辑,实现复杂的cookie信息缓存到服务端
if (Options.SessionStore != null)
{
if (_sessionKey != null)
{
await Options.SessionStore.RemoveAsync(_sessionKey);
}
_sessionKey = await Options.SessionStore.StoreAsync(ticket);
var principal = new ClaimsPrincipal(
new ClaimsIdentity(
new[] { new Claim(SessionIdClaim, _sessionKey, ClaimValueTypes.String, Options.ClaimsIssuer) },
Options.ClaimsIssuer));
ticket = new AuthenticationTicket(principal, null, Scheme.Name);
}
// 加密票据
var cookieValue = Options.TicketDataFormat.Protect(ticket, GetTlsTokenBinding());
// 设置response响应头
Options.CookieManager.AppendResponseCookie(
Context,
Options.Cookie.Name,
cookieValue,
signInContext.CookieOptions); var signedInContext = new CookieSignedInContext(
Context,
Scheme,
signInContext.Principal,
signInContext.Properties,
Options);
// 登录后的事件处理
await Events.SignedIn(signedInContext); var shouldRedirect = Options.LoginPath.HasValue && OriginalPath == Options.LoginPath;
await ApplyHeaders(shouldRedirect, signedInContext.Properties); Logger.AuthenticationSchemeSignedIn(Scheme.Name);
}
// 登出
protected async override Task HandleSignOutAsync(AuthenticationProperties properties); private async Task ApplyHeaders(bool shouldRedirectToReturnUrl, AuthenticationProperties properties);
// 权限不足
protected override async Task HandleForbiddenAsync(AuthenticationProperties properties)
{
var returnUrl = properties.RedirectUri;
if (string.IsNullOrEmpty(returnUrl))
{
returnUrl = OriginalPathBase + OriginalPath + Request.QueryString;
}
var accessDeniedUri = Options.AccessDeniedPath + QueryString.Create(Options.ReturnUrlParameter, returnUrl);
var redirectContext = new RedirectContext<CookieAuthenticationOptions>(Context, Scheme, Options, properties, BuildRedirectUri(accessDeniedUri));
await Events.RedirectToAccessDenied(redirectContext);
}
// 未认证用户,访问保护的资源
protected override async Task HandleChallengeAsync(AuthenticationProperties properties)
{
// 通过配置信息获取重定向url
var redirectUri = properties.RedirectUri;
if (string.IsNullOrEmpty(redirectUri))
{
redirectUri = OriginalPathBase + OriginalPath + Request.QueryString;
} var loginUri = Options.LoginPath + QueryString.Create(Options.ReturnUrlParameter, redirectUri);
var redirectContext = new RedirectContext<CookieAuthenticationOptions>(Context, Scheme, Options, properties, BuildRedirectUri(loginUri));
// 重定向到登录页面
await Events.RedirectToLogin(redirectContext);
}
}

以上就是cookie认证的核心实现,代码注释比较详细,接下来我大致描述一下cookie认证的处理逻辑,其实跟传统的Forms或者Katana的cookie认证思路差不多。
1.首先获取请求cookie,解密并创建ticket票据。
2.如果配置了sessionstore方案,通过sessionkey获取用户完整的声明信息。
3.校验过期,如果未过期。
4.更新cookie,条件为过期时间范围已过半。
5.校验用户信息,主要是针对cookie未失效,用户声明信息发生变更。
6.返回AuthenticateResult认证结果对象。
以上6点就是我个人针对NETCOREcookie认证的理解。接下来我们一起看看,认证中间件是如何关联它们,实现我们的系统认证。
认证中间件
下面我们看看认证中间件的定义。

 public class AuthenticationMiddleware
{
#region Fields private readonly RequestDelegate _next; #endregion #region Ctor public AuthenticationMiddleware(IAuthenticationSchemeProvider schemes, RequestDelegate next)
{
Schemes = schemes ?? throw new ArgumentNullException(nameof(schemes));
_next = next ?? throw new ArgumentNullException(nameof(next));
} #endregion #region Properties public IAuthenticationSchemeProvider Schemes { get; set; } #endregion #region Methods public async Task Invoke(HttpContext context)
{
context.Features.Set<IAuthenticationFeature>(new AuthenticationFeature
{
OriginalPath = context.Request.Path,
OriginalPathBase = context.Request.PathBase
}); var handlers = context.RequestServices.GetRequiredService<IAuthenticationHandlerProvider>();
foreach (var scheme in await Schemes.GetRequestHandlerSchemesAsync())
{
try
{
if (await handlers.GetHandlerAsync(context, scheme.Name) is IAuthenticationRequestHandler handler && await handler.HandleRequestAsync())
return;
}
catch
{
}
} var defaultAuthenticate = await Schemes.GetDefaultAuthenticateSchemeAsync();
if (defaultAuthenticate != null)
{
var result = await context.AuthenticateAsync(defaultAuthenticate.Name);
if (result?.Principal != null)
{
context.User = result.Principal;
}
} await _next(context);
} #endregion
}

如上认证中间件就是这么简单,关于中间件的原理可以参看我上一篇帖子。
1.首先从DI里面获取IAuthenticationHandlerProvider的默认实现类AuthenticationHandlerProvider。
2.从schemes里面获取所有实现IAuthenticationRequestHandler接口的handler,没有什么特别的,就是多了一个请求方法,后续我会介绍,暂时我们把它理解为三方认证的实现handler。
3.如果有注册该handler实例,将调用认证逻辑。
4.如果没有注册requesthandler实例,获取默认scheme。
5.从指定的scheme里面获取具体认证handler实现认证。
6.如果认证成功,返回result,并赋值httpcontext.user属性,完成认证。

最后总结

本来打算把NETCORE的授权也一并讲完,实在想睡觉了,今天就到这吧。下面我来做个简单的总结吧,关于NET平台甚至NETCORE基于cookie认证的实现思路大致是一样的,只是细节上面的区别,当然我理解的可能有些错误。我们学习微软web平台的认证授权,其一是更好的掌握这个平台,其二是学习他的设计思路,当我们自己在实际开发中碰到安全相关的问题,如何去合理设计,更好的保证系统的安全性等等。
