HttpContext SignInAsync 因 Cookie 和声明而失败

Question

我有一个 ASP.NET CORE 应用程序，我尝试添加一个使用 Cookie 进行身份验证的登录。

我有以下代码

启动文件

public void ConfigureServices(IServiceCollection services)
        {
            services.AddAuthentication("CookieAuth")
                .AddCookie("CookieAuth", config =>
                {
                    config.Cookie.Name = "GroupHome.Cookie";
                    config.LoginPath = "/Account/SignIn";
                });
        ...

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
       ...
            app.UseRouting();

            app.UseAuthentication();

            app.UseAuthorization();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapRazorPages();
            });
        }
      ...

登录.cs

public IActionResult Login(LoginModel lm)
       {
           using (var ctx = new GroupHomeContext())
           {
               try {
                   var user = ctx.Logins.SingleOrDefault(er => er.UserName == lm.UserName);
                   if (Decrypt(user.Password) == lm.Password)
                   {
                       var employee = ctx.Employees.SingleOrDefault(em => em.EmployeeId == user.EmployeeId);
                       var employeeRole = ctx.EmployeeToRoles.SingleOrDefault(er => er.EmployeeId == employee.EmployeeId);
                       var Role = ctx.Roles.SingleOrDefault(rl => rl.RoleId == employeeRole.RoleId);

                       var GroupHomeClaims = new List<Claim>() { new Claim(ClaimTypes.NameIdentifier, employee.EmployeeId.ToString()), new Claim(ClaimTypes.Email, employee.Email), new Claim(ClaimTypes.Role, employeeRole.RoleId.ToString()) };
                       var GroupHomeIdentity = new ClaimsIdentity(GroupHomeClaims, "Group Home Identity");
                       var userPrincipal = new ClaimsPrincipal(new[] { GroupHomeIdentity });

                       if (userPrincipal != null)
                       {
                           HttpContext.SignInAsync(userPrincipal);  <----- ERROR IS HERE
                           return RedirectToAction("/Dashboard/Employees");
                       }
                       return RedirectToAction("/Account/SignIn");
                   }
                   return RedirectToAction("/Account/SignIn");
               }
               catch (Exception ex)
               {
                   return RedirectToAction("/Account/SignIn");

               }
           }
       }

在我配置的项目中

并且当用户登录所有数据库验证过程都可以，但是当我尝试将 ClaimsPrincipal 设置为 HttpContext.SignInAsync() 时出现以下错误。

您正在调用异步方法SignInAsync ，我想您也应该等待它并使方法异步。
