一旦用戶通過Asp.Net中的成員資格和角色創建新帳戶，我該如何進行身份驗證

Question

我在Asp.Net Membership中創建了一個自定義CreateUser。 現在我想要的是當創建用戶時，它應該被重定向為default.aspx頁面上的loggedIn用戶。 我如何驗證和重定向到默認頁面。 我不希望他再次登錄，但是當用戶成功創建時，它應該自動登錄並轉到默認頁面。

這是我的代碼。

public string AddUser(string UserName, string FirstName, string LastName, string Gender, string EmailID, string Password, string Mobile, string SecurityQuestion, string SecurityAnswer)
    {
        MembershipCreateStatus CreateStatus;

        MembershipUser newUser = Membership.CreateUser(UserName, Password, EmailID, SecurityQuestion, SecurityAnswer, true, out CreateStatus);

        if (CreateStatus == MembershipCreateStatus.Success)
        {

            Guid newUserId = (Guid)newUser.ProviderUserKey;

            if (RegisterCustomFields(newUserId, FirstName, LastName, Gender, Mobile) != 0)
            {
                Roles.AddUserToRole(newUser.UserName, "User");
                ReturnMsg = "Successfully Created ";
            }
            else
            {
                Membership.DeleteUser(newUser.UserName);
                ReturnMsg = "Error Creating User";
            }

        }
        else
        {

            switch (CreateStatus)
            {
                case MembershipCreateStatus.DuplicateUserName:
                    ReturnMsg = "There already exists a user with this username.";
                    break;

                case MembershipCreateStatus.DuplicateEmail:
                    ReturnMsg = "There already exists a user with this email address.";
                    break;
                case MembershipCreateStatus.InvalidEmail:
                    ReturnMsg = "There email address you provided in invalid.";
                    break;
                case MembershipCreateStatus.InvalidAnswer:
                    ReturnMsg = "There security answer was invalid.";
                    break;
                case MembershipCreateStatus.InvalidPassword:
                    ReturnMsg = "The password you provided is invalid. It must be seven characters long and have at least one non-alphanumeric character.";
                    break;
                default:
                    ReturnMsg = "There was an unknown error; the user account was NOT created.";
                    break;
            }


        }

        return ReturnMsg;

    }

注冊成功后，請編寫以下代碼。 Server.Transfer的（ “〜/ Default.aspx的”）;

對於身份驗證：不確定您是否想知道他們是“已注冊”用戶還是已登錄（如登錄狀態所示）

這是要知道他們是否已登錄（登錄狀態使用的內容）：

System.Web.HttpContext.Current.User.Identity.IsAuthenticated;

嘗試這個：

protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
        {
            if(Membership.ValidateUser(Login1.UserName, Login1.Password))
            {
                Response.Redirect("default.aspx");
                // Set the user as logged in?
            }

        }

Answer 2

如果您使用FormsAuthentication：

FormsAuthentication.SetAuthCookie(userName, isPrsistent);

如果您使用Asp.Net MVC，那么：

return RedirectToAction("Index", "Home");

對於WebForms，請參閱user1237131 answer

Answer 3

由於您已注冊用戶但未在成功注冊后驗證登錄，因此用戶未自動登錄

因此，在您發現用戶已成功注冊到應用程序后，在注冊后，他將被添加到特定角色。 然后，您可以使用以下代碼驗證用戶。

 if (Membership.ValidateUser(UserName, password.Text))
      {
      string[] role = Roles.GetRolesForUser(username.Text);
      string userrole = role[0].ToString();

      FormsAuthentication.SetAuthCookie(UserName, true);
      // Above line will create a Cookie on Browser and you can use this to check the authentication of the user. 
      if (userrole == "User")
          {
              Response.Redirect("~/Default.aspx", true);
          }
      else
          {
              Response.Redirect("~/UnAuthorizedPage.aspx", true);
          }
 }

希望它能幫到你:)
