Asp.NET Identity 2给出“无效令牌”错误

我正在使用 Asp.Net-Identity-2， 并且尝试使用以下方法来验证电子邮件验证代码。但是我收到 “无效令牌” 错误消息。

• 我的应用程序的用户管理器是这样的：

  public class AppUseRMANager : UseRMANager<AppUser>
  

  {
  public AppUseRMANager(IUserStore storE) : base(storE) { }

  public static AppUseRMANager Create(IdentityFactoryOptions<AppUseRMANager> options,IOwinContext context)
  {
      AppIdentityDbContext db = context.Get<AppIdentityDbContext>();
      AppUseRMANager manager = new AppUseRMANager(new UserStore<AppUser>(db));
  
      manager.passwordValidator = new passwordValidator { 
          requiredLength = 6,requireNonLetterOrDigit = false,requireDigit = false,requireLowercase = true,requireUppercase = true
      };
  
      manager.UserValidator = new UserValidator<AppUser>(manager)
      {
          AllowOnlyAlphanumericUserNames = true,requireUniqueEmail = true
      };
  
      var dataProtectionProvider = options.DataProtectionProvider;
  
      //token life span is 3 hours
      if (dataProtectionProvider != null)
      {
          manager.UserTokenProvider =
             new DataProtectorTokenProvider<AppUser>
                (dataProtectionProvider.Create("ConfirmationToken"))
             {
                 TokenLifespan = TimeSpan.FromHours(3)
             };
      }
  
      manager.Emailservice = new Emailservice();
  
      return manager;
  } //Create
  

  } //class
  } //namespace

• 我生成令牌的操作是（即使我在此处检查令牌，也会收到“无效令牌”消息）：

  [AllowAnonymous]
  

  [httpPost]
  [ValidateAntiForgeryToken]
  public ActionResult Forgotpassword(String email)
  {
  if (ModelState.IsValid)
  {
  AppUser user = UseRMANager.FindByEmail(email);
  if (user == null || !(UseRMANager.IsEmailConfirmed(user.Id)))
  {
  // Returning without warning anything wrong&Hellip;
  return View(“../Home/Index”);

      } //if
  
      String code = UseRMANager.GeneratepasswordResetToken(user.Id);
      String callBACkUrl = Url.Action("Resetpassword","Admin",new { Id = user.Id,code = httpUtility.UrlEncode(codE) },protocol: request.Url.scheR_479_11845@E);
  
      UseRMANager.SendEmail(user.Id,"Reset password Link","Use the following  link to reset your password: <a href=\"" + callBACkUrl + "\">link</a>");
  
      //This 2 lines I use tho debugger propose. The result is: "Invalid token" (???)
      IdentityResult result;
      result = UseRMANager.ConfirmEmail(user.Id,codE);
  }
  
  // If we got this far,something failed,redisplay form
  return View();
  

  } //Forgotpassword

• 我检查令牌的操作是（在这里，当我检查结果时，我总是得到“无效令牌”）：

  [AllowAnonymous]
  

  public async Task Resetpassword(String id,String codE)
  {

  if (id == null || code == null)
  {
      return View("Error",new String[] { "Invalid params to reset password." });
  }
  
  IdentityResult result;
  
  try
  {
      result = await UseRMANager.ConfirmEmailAsync(id,codE);
  }
  catch (InvalidoperationException ioE)
  {
      // ConfirmEmailAsync throws when the id is not found.
      return View("Error",new String[] { "Error to reset password:<br/><br/><li>" + ioe.message + "</li>" });
  }
  
  if (result.Succeeded)
  {
      AppUser objUser = await UseRMANager.FindByIdAsync(id);
      ResetpasswordModel model = new ResetpasswordModel();
  
      model.Id = objUser.Id;
      model.Name = objUser.UserName;
      model.Email = objUser.Email;
  
      return View(model);
  }
  
  // If we got this far,something failed.
  String strErrorMsg = "";
  foreach(String strError in result.Errors)
  {
      strErrorMsg += "<li>" + strError + "</li>";
  } //foreach
  
  return View("Error",new String[] { strErrorMsg });
  

  } //ForgotpasswordConfirmation

我不知道可能遗漏了什么或出了什么问题&Hellip;
