1、新建.netCore webapi项目

2、安装swagger ,通过 Package Manager 控制台:Install-Package Swashbuckle.AspNetCore

3、修改Startup.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.HttpsPolicy;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using Microsoft.Extensions.Options; namespace CoreTest
{
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1); //1、注册服务Swagger
services.AddSwaggerGen(options =>
{
options.SwaggerDoc("v1", new Swashbuckle.AspNetCore.Swagger.Info
{
Version = "v1",
Title = "My API",
Description = "by JiaJia"
});
});
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseHsts();
}
app.UseHttpsRedirection();
app.UseMvc(); //2、添加到管道
#if DEBUG
app.UseSwagger();
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
// c.DocExpansion(DocExpansion.None);
});
#endif
}
}
}

4、访问 Swagger UI 地址

http://localhost:60238/swagger/index.html

5、添加备注

1、在项目属性的 生成 => 输出 中勾选 XML文档文件。

2、在 Start.cs => ConfigureServices 方法中的 AddSwaggerGen 处增加 IncludeXmlComments 处理。

//1、注册服务Swagger
services.AddSwaggerGen(options =>
{
options.SwaggerDoc("v1", new Swashbuckle.AspNetCore.Swagger.Info
{
Version = "v1",
Title = "My API",
Description = "by JiaJia"
});
//在 Start.cs => ConfigureServices 方法中的 AddSwaggerGen 处增加 IncludeXmlComments 处理。
options.IncludeXmlComments(string.Format("{0}/CoreTest.xml",
AppDomain.CurrentDomain.BaseDirectory)); /*或者这种添加方式//为 Swagger JSON and UI设置xml文档注释路径
var basePath = Path.GetDirectoryName(typeof(Program).Assembly.Location);//获取应用程序所在目录(绝对,不受工作目录影响,建议采用此方法获取路径)
var xmlPath = Path.Combine(basePath, "CoreTest.xml");//和项目名对应
options.IncludeXmlComments(xmlPath);*/
});

3、控制器对Action添加注释信息

/// <summary>
/// 根据ID获取用户信息
/// </summary>
/// <param name="id">用户ID</param>
/// <returns>用户信息</returns>
[HttpGet("{id}")]
public ActionResult<string> Get(int id)
{
return "user info";
}

运行报错:

原因:生成的xml文件,路径不对,导致的/swagger/v1/swagger.json提示报错。

解决方案:(指定输出路径默认空白,需要填写:bin\Debug\),而且默认的(CoreTest.xml)xml文件,与Startup的文件必须对应。

最终效果:

4、不想每一个方法都这么加注释,可以这么配置(对当前项目进行配置,可以忽略警告,记得在后边加上分号 ;1591):

二、接口执行时间分析——MiniProfiler

搭建MiniProfiler

1、引入nuget包:

Install-Package MiniProfiler.AspNetCore.Mvc

2、然后,在startup.cs 中配置服务ConfigureServices:

//注册服务MiniProfiler
services.AddMiniProfiler(options =>
{
options.RouteBasePath = "/profiler";//注意这个路径要和下边 index.html 脚本配置中的一致,
(options.Storage as MemoryCacheStorage).CacheDuration = TimeSpan.FromMinutes();
});

3、最后,调用下中间件即可:

//调用MiniProfiler中间件
app.UseMiniProfiler();

当前这个时候还不能使用,我们还需要在 Swagger 中进行配置,以便它能在 swagger 中使用。

在 Swagger 中配置 MiniProfiler

上边我们在配置中已经启动了服务,接下来就需要设置如何在 swagger 中展示了,这个时候我们就需要自定义我们的swagger主页了,以前我们是用的默认的index.html,现在咱们需要自定义一个:

从官网 Github 上,下载最新的 index.html:https://github.com/swagger-api/swagger-ui/blob/master/dist/index.html

const ui = SwaggerUIBundle(configObject); // Apply OAuth config
ui.initOAuth(oauthConfigObject);
}
</script>
</body>
</html>

然后添加到项目中,我是放到了根路径了:

要把这个文件设置成嵌入资源的类型:

接下来,在 Index.html 文件中,增加配置脚本(我是在顶部写的,Head应该也可以):

<script async="async" id="mini-profiler" src="/profiler/includes.min.js?v=4.0.138+gcc91adf599"
data-version="4.0.138+gcc91adf599" data-path="/profiler/"
data-current-id="4ec7c742-49d4-4eaf-8281-3c1e0efa748a" data-ids="" data-position="Left"
data-authorized="true" data-max-traces="15" data-toggle-shortcut="Alt+P"
data-trivial-milliseconds="2.0" data-ignored-duplicate-execute-types="Open,OpenAsync,Close,CloseAsync">
</script>

具体的参数请自行研究吧,基本都能看懂,比如版本,

/profiler的路径,position的位置显示(我是左边),

authorized的是否权限,

max-traces最多显示多少条(15)等等。

完整index.html文件内容

const ui = SwaggerUIBundle(configObject); // Apply OAuth config
ui.initOAuth(oauthConfigObject);

</script>
</body>
</html>

然后我们修改下中间件去调用我们这个 index.html 页面:

app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
// 将swagger首页,设置成我们自定义的页面,记得这个字符串的写法:解决方案名.index.html
c.IndexStream = () => GetType().GetTypeInfo().Assembly.GetManifestResourceStream("CoreTest.index.html");
});

最后,记得一定要配置了使用静态资源文件的中间件:

 app.UseStaticFiles();

现在已经配置好了 MiniProfiler 和 Swagger了,运行页面左上角

是不是感觉挺好的!这样的时间都有了,然后还记得上边配置的 /profiler 么,我们点击 share 就能看到了,这里不细说了,大家自己玩一玩。现在有一个问题就是,我总不能每一个 api 接口都这么写吧,多麻烦呀!机智如你,这个时候 AOP 日志记录又派上用场了!

切面 MiniFilter分析

1、只需要在 AOP 日志记录中,配置 MiniProfiler 即可:
