当前上下文中不存在名称“DefaultAuthenticationTypes”
我正在尝试在我的Web应用程序中实现基于角色的授权,如下所示:
[HttpPost] [ActionName("Login")] public ActionResult Login(LoginViewModel model) { if (ModelState.IsValid) { string userName = model.Username; string[] userRoles = (string[])Session["UserRoles"]; ClaimsIdentity identity = new ClaimsIdentity(DefaultAuthenticationTypes.ApplicationCookie); identity.AddClaim(new Claim(ClaimTypes.NameIdentifier, userName)); userRoles.ToList().ForEach((role) => identity.AddClaim(new Claim(ClaimTypes.Role, role))); identity.AddClaim(new Claim(ClaimTypes.Name, userName)); AuthenticationManager.SignIn(identity); return RedirectToAction("Success"); } else { return View("Login",model); } }
我在两行上出错了:
1.ClaimsIdentity identity = new ClaimsIdentity(DefaultAuthenticationTypes.ApplicationCookie);
和:
2.AuthenticationManager.SignIn(identity);
错误1:
the name 'DefaultAuthenticationTypes' does not exist in the current context
错误2是:
Authentication manager does not contains definition for SignIn
我试图找到一个解决方案如何实现这个,但我找不到任何与错误相关的东西。
DefaultAuthenticationTypes
是Identity框架的一部分,可在Microsoft.AspNet.Identity
命名空间中找到。
要使用它,请在文件顶部添加一个using
using Microsoft.AspNet.Identity; //...other code identity = new ClaimsIdentity(DefaultAuthenticationTypes.ApplicationCookie);
或直接打电话
identity = new ClaimsIdentity(Microsoft.AspNet.Identity.DefaultAuthenticationTypes.ApplicationCookie);
第二个问题已经在你的另一个问题中处理了
