ASP.NET MVC学习笔记（二）登陆验证

书上的验证时在配置文件中直接声明用户名和密码，想改成从数据验证账号和密码，搞了一下午都没高出来，不断的调试，发现

var table = userInfo.Tables.FirstOrDefault(x => x.Name == user.Name);

这句代码有问题，一直时Null,各种百度无法解决，就把它转成userInfo.Tables.AsQueryable();了。完美解决了

控制器代码

 public class AccountController : Controller
    {
        IAuthProvider authProvider;
        ITaableInfo userInfo;
        public AccountController(IAuthProvider autho,ITaableInfo info)
        {
            authProvider = autho;
            //获得用户数据
            userInfo = info;
            //EFDbcontext context = new EFDbcontext();
            //context.SaveChanges();
        }
        public ViewResult Login2()
        {
            return View();
        }
        //[HttpPost]
        //public ActionResult Login(LoginViewModel model, string returnUrl)
        //{
        //    if (ModelState.IsValid)
        //    {

        //        if (authProvider.Authenticate(model.Name, model.PassWord))
        //        {
        //            return Redirect(returnUrl ?? Url.Action("Index", "Admin"));
        //        }
        //        else
        //        {
        //            ModelState.AddModelError("", "Incorrect userName,passWord");
        //            return View();
        //        }

        //    }
        //    else
        //    {
        //        return View();
        //    }
        //}
        [HttpPost]
        public ActionResult Login2(Admin user, string returnUrl)
        {

            //foreach (var B in userInfo.Tables)
            //{
            //    string str = B.Name;
            //}
            string name = user.Name;
            string pwd = user.PassWord;
            //var table = userInfo.Tables.FirstOrDefault(x => x.Name == user.Name);
            var table = userInfo.Tables.AsQueryable();
           var info= table.FirstOrDefault(x => x.Name == user.Name);
            if (info != null)
            {
             //string  url=  Url.Action("Index", "Admin").ToString();
                FormsAuthentication.SetAuthCookie(info.Name, false);
                //重新定向到Admin/Index页面
                return Redirect(returnUrl??Url.Action("Index","Admin"));
            }
            else
            {
                return View();
            }
        }
    }

html代码

@model SpotrsStore.Domain.Entities.Admin

@{
    ViewBag.Title = "Login2";
    Layout = "~/Views/Shared/_AdminLayout.cshtml";
}

<div class="panel">
    <div class="panel-heading">
        <h3>log in</h3>
    </div>
    <div class="panel-body">
        <p class="lead">please log in access the administrator area</p>
        @using (Html.BeginForm())
        {
            Html.ValidationSummary();
            <div class="form-group">
                <label>username</label>
                @Html.TextBoxFor(x => x.Name, new { @class = "form-control" })
            </div>
            <div class="form-group">
                <label>password</label>
                @Html.PasswordFor(x => x.PassWord, new { @class = "form-control" })

            </div>
            <input type="submit" value="log in" class="btn btn-primary" />

        }
    </div>
</div>

配置文件代码

<authentication mode="Forms">
      <forms loginUrl="~/Account/Login2"></forms>
    </authentication>

重新的定向的的页面的控制器要加 [Authorize]//授权属性，加在类名上面或动作方法上面视情况所选择
