MVC（ASP.NET身份）使用實體框架自定義登錄狀態

Question

我有一個使用實體框架的現有數據庫。註冊和登錄工作，但我想爲Signin狀態添加一個附加狀態：未經授權。

下面是在登錄的代碼：我添加的代碼段以上部分向你展示我想要什麼

public async Task<ActionResult> Login(LoginViewModel model, string returnUrl) 
     { 
      if (!ModelState.IsValid) 
      { 
       return View(model); 
      } 

      // This doesn't count login failures towards account lockout 
      // To enable password failures to trigger account lockout, change to shouldLockout: true 
      var result = await SignInManager.PasswordSignInAsync(model.UserName, model.Password, model.RememberMe, shouldLockout: false); 
      switch (result) 
      { 
       case SignInStatus.Success: 
        return RedirectToLocal(returnUrl); 
       'case SignInStatus.UnAuthorized: 
        return View("UnAuthorized");' //I want to add this 
       case SignInStatus.LockedOut: 
        return View("Lockout"); 
       case SignInStatus.RequiresVerification: 
        return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = model.RememberMe }); 
       case SignInStatus.Failure: 
       default: 
        ModelState.AddModelError("", "Invalid login attempt."); 
        return View(model); 
      } 
     } 

。我找到了上面使用的狀態。在下面的代碼片段中提供，但我無法修改此文件：

namespace Microsoft.AspNet.Identity.Owin 
{ 
    // 
    // Summary: 
    //  Possible results from a sign in attempt 
    public enum SignInStatus 
    { 
     // 
     // Summary: 
     //  Sign in was successful 
     Success = 0, 
     // 
     // Summary: 
     //  User is locked out 
     LockedOut = 1, 
     // 
     // Summary: 
     //  Sign in requires addition verification (i.e. two factor) 
     RequiresVerification = 2, 
     // 
     // Summary: 
     //  Sign in failed 
     Failure = 3 
    } 
} 

我可能會補充說我是MVC的新手。

任何人都可以指出我正確的方向能夠添加自定義登錄狀態？ PS：授權字段確實存在於我的數據庫中，如果用戶已授權或不登錄，這是我想要提取的地方。

感謝您的幫助。

所以我GOOGLE了很多，似乎SignInManager的狀態不能被修改？也許我錯了，因爲我對MVC和實體框架的知識非常有限。

所以我找到了一個解決辦法，並通過實際的登錄代碼運行之前添加以下沒有使用LINQ我自己的驗證：

using (EFNameEntities db = new EFNameEntities()) 
     { 
      var UserData = from ANU in db.AspNetUsers 
          where ANU.UserName == model.UserName 
          select new 
          { 
           ANU.isAuthorized, 
           ANU.isActive 
          }; 

      foreach (var c in UserData) 
      { 
       //If User is NOT Authorized to log in 
       if (!Convert.ToBoolean(c.isAuthorized)) 
       { 
        ModelState.AddModelError("", "This User is not Authorized to Login."); 
        return View(model); 
       } 
       else 
       { 
        //If User is NOT Active 
        if (!Convert.ToBoolean(c.isActive)) 
        { 
         ModelState.AddModelError("", "This User is not Active."); 
         return View(model); 
        } 
       } 
      } 


     } 

所以整個登錄的ActionResult看起來是這樣的：

[HttpPost] 
    [AllowAnonymous] 
    [ValidateAntiForgeryToken] 
    public async Task<ActionResult> Login(LoginViewModel model, string returnUrl) 
    { 
     if (!ModelState.IsValid) 
     { 
      return View(model); 
     } 

     using (EFNameEntities db = new EFNameEntities()) 
     { 
      var UserData = from ANU in db.AspNetUsers 
          where ANU.UserName == model.UserName 
          select new 
          { 
           ANU.isAuthorized, 
           ANU.isActive 
          }; 

      foreach (var c in UserData) 
      { 
       //If User is NOT Authorized to log in 
       if (!Convert.ToBoolean(c.isAuthorized)) 
       { 
        ModelState.AddModelError("", "This User is not Authorized to Login."); 
        return View(model); 
       } 
       else 
       { 
        //If User is NOT Active 
        if (!Convert.ToBoolean(c.isActive)) 
        { 
         ModelState.AddModelError("", "This User is not Active."); 
         return View(model); 
        } 
       } 
      } 


     } 

     // This doesn't count login failures towards account lockout 
     // To enable password failures to trigger account lockout, change to shouldLockout: true 
     var result = await SignInManager.PasswordSignInAsync(model.UserName, model.Password, model.RememberMe, shouldLockout: true); 
     switch (result) 
     { 
      case SignInStatus.Success: 
       return RedirectToLocal(returnUrl); 
      //case SignInStatus.UnAuthorized: 
      // return View("UnAuthorized"); 
      case SignInStatus.LockedOut: 
       return View("Lockout"); 
      case SignInStatus.RequiresVerification: 
       return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = model.RememberMe }); 
      case SignInStatus.Failure: 
      default: 
       //Incorrect password or user does not exist 
       ModelState.AddModelError("", "Invalid login attempt."); 
       return View(model); 
     } 
    }
