Asp.Net Core 2.0 登陸功能 Cookie（學習）

AdminController中添加引用：

1 using Microsoft.AspNetCore.Authorization;

Index添加[Authorize]許可權要求：

1 [Authorize]
2 public IActionResult Index()
3 {
4     return View();
5 }

 StartUp.cs中添加引用：

1 using Microsoft.AspNetCore.Authentication;
2 using Microsoft.AspNetCore.Authentication.Cookies;

StartUp.cs ConfigureServices中添加常量：

1 public void ConfigureServices(IServiceCollection services)
2 {
3     services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
          .AddCookie();
4     services.AddMvc();
5 }

添加中間件：

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    app.UseAuthentication();
}

 此時，訪問Admin頁面，自動跳轉至Account/Login?ReturnUrl=%2FAdmin
