  //获取到用户信息
              var user = await _userService.UserLogin(vm);

  在Startup.cs

  文件中

   public void ConfigureServices(IServiceCollection services){
  services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)

                     .AddCookie(CookieAuthenticationDefaults.AuthenticationScheme, o =>

                     {

                         o.LoginPath = new PathString("/manage/home/Login");

                         o.AccessDeniedPath = new PathString("/Error/Forbidden");

                     });

  }
  
  
   public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
          {
   //注意app.UseAuthentication方法一定要放在下面的app.UseMvc方法前面，否者后面就算调用HttpContext.SignInAsync进行用户登录后，使用
              //HttpContext.User还是会显示用户没有登录，并且HttpContext.User.Claims读取不到登录用户的任何信息。
              //这说明Asp.Net OWIN框架中MiddleWare的调用顺序会对系统功能产生很大的影响，各个MiddleWare的调用顺序一定不能反
              app.UseAuthentication();
              app.UseAuthorization();
  }
