如何通过点击链接从控制器调用方法

如果用这个链接丢失了以前的电子邮件,我需要重新发送给用户的激活链接。

所以,我在Login方法中检查了用户状态:

        [HttpPost]
        [AllowAnonymous]
        [ValidateAntiForgeryToken]
        public ActionResult Login(LoginModel model, string returnUrl)
        {
            bool isConfirmed = (model == null) ? false : WebSecurity.IsConfirmed(model.UserName);
            string errorMsg = "Login or password is incorrect.";

        if (isConfirmed)
        {
            if (ModelState.IsValid && WebSecurity.Login(model.UserName, model.Password, persistCookie: model.RememberMe))
            {
                return RedirectToLocal(returnUrl);
            }
        }
        else
        {
            if (WebSecurity.UserExists(model.UserName))
            {
                errorMsg = "Your account is not activated. Click <a href=\"" + Url.Content("~/Account/ResendConfirmationLink") + "?id=" + model.UserName +"\" class=\"alert-link\">here</a> for resend email with activation link.";
            }
        }

        // If we got this far, something failed, redisplay form
        ModelState.AddModelError("", errorMsg);
        return View(model);
    }

上面的代码生成http://localhost:64612/Account/ResendConfirmationLink?id=nickname之类的链接,所以通过点击它我们应该调用以下方法(来自Account控制器):

        [HttpGet]
        public ActionResult ResendConfirmationLink(string id)
        {
            using (ChatContext chatContxt = new ChatContext())
            {
                var tsqlQuery = string.Format("SELECT [ConfirmationToken] FROM [webpages_Membership] WHERE [UserId] IN (SELECT [UserId] FROM [User] WHERE [UserName] LIKE '{0}')", id);
                string confirmationToken = chatContxt.Database.SqlQuery<string>(tsqlQuery).First();
                tsqlQuery = string.Format("SELECT [Email] FROM [User] WHERE [UserName] LIKE '{0}'", id);
                string email = chatContxt.Database.SqlQuery<string>(tsqlQuery).First();
                SendEmail(email, confirmationToken);
            }
            return View("Login");
        }

但是永远不会调用方法ResendConfirmationLink()!重新加载登录视图,并将网址转换为http://localhost:64612/Account/Login?ReturnUrl=%2fAccount%2fResendConfirmationLink%3fid%3dusername1&id=username1

我做错了什么?为什么方法不通过点击链接来调用?

您需要在[AllowAnonymous]操作中添加ResendConfirmationLink注释。

它希望用户在调用您不想要的方法之前进行身份验证。

你犯了两个错误,如下所示

  1. 首先,您必须将[AllowAnonymous]属性添加到R​​esendConfirmationLink方法。

  2. 您需要更改您的resedconfirmation网址

    http://localhost:64612/Account/ResendConfirmationLink?username=nickname
    
  3.       http://localhost:64612/Account/ResendConfirmationLink?id=nickname
