c# – 当前上下文中不存在名称“DefaultAuthenticationTypes”
作者:互联网
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内容.
最佳答案:
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使用
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);
第二个问题已在另一个问题here中处理过
