如何更新ASP.NET身份中的UserManager？

Question

美好的一天，

我在asp.net Identity 2.0 MVC5中創建並分配了一個帶有密碼的用戶（並且幾乎不是新的）並且在登錄時;我指示用戶創建（更新）他/她的帳戶。

一切順利，但是當用戶提交更新時，它並不反映在數據庫中。它似乎錯過了我的代碼中的正確邏輯。這是我的ViewModel和控制器。

拜託，我需要你的幫助。

public class EditUserViewModel 
     { 
      [Key] 
      public string Id { get; set; } 

      [Required] 
      [Display(Name = "Surname")] 
      public string FirstName { get; set; } 

      [Required] 
      [Display(Name = "Last Name")] 
      public string LastName { get; set; } 

      [Required] 
      [Display(Name = "Username")] 
      public string Username { get; set; } 

      [Required] 
      [EmailAddress] 
      [Display(Name = "Email")] 
      public string Email { get; set; } 

      [Required] 
      [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 8)] 
      [DataType(DataType.Password)] 
      [Display(Name = "Password")] 
      public string Password { get; set; } 

      [DataType(DataType.Password)] 
      [Display(Name = "Confirm password")] 
      [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")] 
      public string ConfirmPassword { get; set; } 

      [Display(Name = "Gender")] 
      public string Gender { get; set; } 

      [Required] 
      [Display(Name = "Mobile Phone")] 
      public string PhoneNumber { get; set; } 

      //[Required] 
      [Display(Name = "Birthday - yyyy/mm/dd")] 
      public DateTime DateOfBirth { get; set; } 

      //public DateTime PostedDate { get; set; } 
     } 


    Controller: 
    [HttpGet, ActionName("profile")] 
      public ActionResult Edit() 
      { 

       return View(); 
      } 

      [HttpPost, ActionName("profile")] 
      [ValidateAntiForgeryToken] 
      public async Task<ActionResult> Edit(EditUserViewModel editUser) 
      { 
       if (ModelState.IsValid && TempData["Username"] != null) 
       { 
        var user = await UserManager.FindByNameAsync(editUser.Username); 

        if (user == null) 
        { 
         return HttpNotFound(); //change error later 
        } 
        user.FirstName = editUser.FirstName; 
        user.LastName = editUser.LastName; 
        user.UserName = editUser.Email; 
        user.Email = editUser.Email; 
        user.PasswordHash = editUser.Password; 


        var userUpdated = await UserManager.UpdateAsync(user); 

        if (!userUpdated.Succeeded) 
        { 
         ModelState.AddModelError("", userUpdated.Errors.First()); 
         return View(); 
        } 
        return RedirectToAction("index", "pages"); 
       } 
       ModelState.AddModelError("", "Something failed!!!"); 
       return View(); 
    }

您不能使用user.PasswordHash，因爲它由UserManager專門設置。您將需要生成一個密碼重置令牌來重置uesrs密碼，如下所示：

[HttpPost, ActionName("profile")] 
[ValidateAntiForgeryToken] 
public async Task<ActionResult> Edit(EditUserViewModel editUser) 
{ 
    if (ModelState.IsValid && TempData["Username"] != null) 
    { 
     var user = await UserManager.FindByNameAsync(TempData["Username"] as string); 
     if (user == null) 
     { 
      return HttpNotFound(); //change error later 
     } 

     user.FirstName = editUser.FirstName; 
     user.LastName = editUser.LastName; 
     user.UserName = editUser.Email; 
     user.Email = editUser.Email; 

     var userUpdated = await UserManager.UpdateAsync(user); 

     if (!string.IsNullOrWhiteSpace(editUser.Password)) 
     { 
      UserManager.UserTokenProvider = new EmailTokenProvider<IdentityUser>(); 
      var resetToken = await UserManager.GeneratePasswordResetTokenAsync(user.Id); 
      var result = await UserManager.ResetPasswordAsync(user.Id, resetToken, editUser.Password); 
     } 

     if (!userUpdated.Succeeded) 
     { 
      ModelState.AddModelError("", userUpdated.Errors.First()); 
      return View(); 
     } 
     return RedirectToAction("index", "pages"); 
    } 

    ModelState.AddModelError("", "Something failed!!!"); 
    return View(); 
}
