如何在第一次单击后禁用电子邮件链接 [英] How to disable an email link after first click

问题描述

我在电子邮件中发送一个带有查询字符串的链接来重置密码。当用户点击链接时，这个重定向到我的网站resetPwd.aspx上的用户，他/她可以在数据库中成功重置密码。

再次如果用户试图打开电子邮件中的链接，则强制要求它不允许用户打开该链接。如何在第二次点击时阻止

电子邮件链接？





我的C＃代码

Hi,
I am sending a link in the email with query string to reset password. When user click on link this redirect to user on my website resetPwd.aspx and he/she can reset password successfully in database.
Again if the user is trying to open the link in email, its compulsory that it cant allow the user to open that link. How to block
the email link in the second click?


My C# code

private void sendEmail(string emailTo, string userId)
{
    string UserName = LoginUser.UserName;
    using (StreamReader reader = File.OpenText(Server.MapPath("~/App_Data/ResetPwdEmailBody.txt")))
    {
        string urlBase = Request.Url.GetLeftPart(UriPartial.Authority) + Request.ApplicationPath;
        string verifyUrl = "/Account/UnlockAccount.aspx?uName=" + UserName + "&id=" + userId;
        string fullUrl = urlBase + verifyUrl;
        MailMessage msg = new MailMessage();
        msg.Subject = "Unlock your account";
        msg.IsBodyHtml = true;
        msg.To.Add(new MailAddress(emailTo, UserName));
        msg.Body = reader.ReadToEnd();
        msg.Body = msg.Body.Replace("<%resetPassword%>", fullUrl);
        msg.Body = msg.Body.Replace("<% UserName %>", UserName);
        msg.Priority = MailPriority.High;
        SmtpClient myClient = new SmtpClient();
        myClient.EnableSsl = false;
        try
        {
            myClient.Send(msg);
        }
        catch (Exception ex)
        {
            LoginUser.FailureText = "Email cannot be send. Error: " + ex.Message;
        }
    }

}
