我在ASP.NET MVC中使用电子邮件验证但它不起作用？ [英] I am using email verification in ASP.NET MVC but it is not working?

问题描述

我在我的asp.net mvc中使用电子邮件方法进行验证，并设置gmail允许应用程序安全访问级别低：但仍然无效。它没有抛出任何异常。早期这段代码完美无缺，电子邮件验证工作正确，但是从最近几天起它无法正常工作。



我有什么试过：

私人ActionResult SendEmail（MailMessage邮件）
 {
 SmtpClient client = new SmtpClient（ ）; 
 client.Host =smtp.gmail.com; 
 client.Port = 587; 
 client.EnableSsl = true; 
 client.UseDefaultCredentials = false; 
 client.DeliveryMethod = SmtpDeliveryMethod.Network; 
 client.Credentials = new System.Net.NetworkCredential（emailid，password）; 
 try 
 {
 client.Send（mail）; 
 
} 
 catch（Exception ex）{return RedirectToAction（home）;} 
返回RedirectToAction（home2）; 
} 
 

 public ActionResult sendemail2（string subjectText，string bodyText，string sendTo，string from）
 {
 string to，bcc，cc，subject，body; 
 
 to = sendTo.Trim（）; 
 bcc =; 
 cc =; 
 subject = subjectText; 
 StringBuilder sb = new StringBuilder（）; 
 sb.Append（bodyText）; 
 body = sb.ToString（）; 
 MailMessage mail = new MailMessage（）; 
 mail.From = new MailAddress（ from）; 
 mail.To.Add（new MailAddress（to））; 
 if（！string.IsNullOrEmpty（bcc））
 {
 mail.Bcc.Add（new MailAddress（bcc））; 
} 
 if（！string.IsNullOrEmpty（bcc））
 {
 mail.Bcc.Add（new MailAddress（cc））; 
} 
 mail.Subject = subject; 
 mail.Body = body; 
 mail.IsBodyHtml = true; 
 
 SendEmail（mail）; 
返回RedirectToAction（home）; 
} 
 

 public ActionResult sendemail3（string textboxemailid）
 {
 string body = System .IO.File.ReadAllText（HostingEnvironment.MapPath（〜/ EmailTemplate /）+text+。cshtml）; 
 var regInfo = db.xyztables.Where（x => x.emailid == textboxemailid）.FirstOrDefault（）; 
 
 var pass = db.xyztables.Where（x => x.emailid == textboxemailid）.Select（x => x.password）.FirstOrDefault（）; 
 
 body = body.Replace（@ ViewBag.pass，pass）; 
 body = body.ToString（）; 
 string from =emailid; 
 sendemail2（你的详细信息，正文，regInfo.emailid，来自）; 
会话[check] =请检查您的电子邮件; 
返回查看（检查）; 
} 
 

 public void sendemail4（int regid）
 {
 string body = System .IO.File.ReadAllText（HostingEnvironment.MapPath（〜/ EmailTemplate /）+Text+。cshtml）; 
 var regInfo = db.xyztables.Where（x => x.id == regid）.FirstOrDefault（）; 
 string regem = db.xyztables.Where（x => x.id == regid）.Select（x => x.emailid）.FirstOrDefault（）; 
 var url =http://xyz.com/+xyztables / Confirm？regem =+ regem; 
 
 body = body.Replace（@ ViewBag.ConfirmationLink，url）; 
 body = body.ToString（）; 
 string from =emailid; 
 BuildEmailTemplate（激活你的账户，正文，regInfo.emailid，来自）; 
 
} 
 
 [HttpPost] 
 
 public ActionResult Signup（string textbox1emailid，string textboxname，string textboxpass，string Create）
 {
 var checkdb = db.xyztables.Where（x => x.emailid == textbox1emailid）.FirstOrDefault（）; 
 if（checkdb == null）
 {
 xyztable table = new xyztable（）; 
 xyztable.emailid = textbox1emailid.ToString（）; 
 xyztable.name = textbox1name.ToString（）; 
 xyztable.password = textbox1pass.ToString（）; 
 xyztable.emailconfirmed = 0; 
 db.xyztables.Add（xyztable）; 
 db.SaveChanges（）; 
 sendemail4（xyztable.id）; 
会话[check] =请检查您的emailid以确认您的帐户; 
返回RedirectToAction（home）; 
} 
 else {Session [message] =Emailid已存在; 
返回查看（登录）; 
} 
} 
 

解决方案

如果它正常工作，现在却不行，问题不太可能是你的代码。这将是一个network\config\gmail问题。 Google可能会面临通过Gmail发送电子邮件的许多问题，因为这是最常见的问题之一。



正确的答案是不使用gmail SMTP服务器，根据您的代码运行位置，使用网络管理员或您的网站主机提供的SMTP服务器。



你不应该花时间去做ASP.NET论坛 [ ^ ]

i am using email method for verification in my asp.net mvc and set gmail allow app security access level low :on but still its not working . Its is not throwing any exception .Earlier this code work perfectly and email verification is done corretly but from last few days it is not working .

What I have tried:

private ActionResult SendEmail(MailMessage mail)
       {
           SmtpClient client = new SmtpClient();
           client.Host = "smtp.gmail.com";
           client.Port = 587;
           client.EnableSsl = true;
           client.UseDefaultCredentials = false;
           client.DeliveryMethod = SmtpDeliveryMethod.Network;
           client.Credentials = new System.Net.NetworkCredential("emailid,"password");
           try
           {
               client.Send(mail);

           }
           catch (Exception ex) { return RedirectToAction("home"); }
           return RedirectToAction("home2");
       }

public ActionResult sendemail2(string subjectText, string bodyText, string sendTo, string from)
       {
           string to, bcc, cc, subject, body;

           to = sendTo.Trim();
           bcc = "";
           cc = "";
           subject = subjectText;
           StringBuilder sb = new StringBuilder();
           sb.Append(bodyText);
           body = sb.ToString();
           MailMessage mail = new MailMessage();
           mail.From = new MailAddress(from);
           mail.To.Add(new MailAddress(to));
           if (!string.IsNullOrEmpty(bcc))
           {
               mail.Bcc.Add(new MailAddress(bcc));
           }
           if (!string.IsNullOrEmpty(bcc))
           {
               mail.Bcc.Add(new MailAddress(cc));
           }
           mail.Subject = subject;
           mail.Body = body;
           mail.IsBodyHtml = true;

           SendEmail(mail);
           return RedirectToAction("home");
       }

public ActionResult sendemail3(string textboxemailid)
       {
           string body = System.IO.File.ReadAllText(HostingEnvironment.MapPath("~/EmailTemplate/") + "text" + ".cshtml");
           var regInfo = db.xyztables.Where(x => x.emailid == textboxemailid).FirstOrDefault();

           var pass = db.xyztables.Where(x => x.emailid == textboxemailid).Select(x => x.password).FirstOrDefault();

           body = body.Replace("@ViewBag.pass", pass);
           body = body.ToString();
           string from = "emailid";
           sendemail2("Your Details", body, regInfo.emailid, from);
           Session["check"] = "Please check your email";
           return View("check");
       }

public void sendemail4(int regid)
  {
      string body = System.IO.File.ReadAllText(HostingEnvironment.MapPath("~/EmailTemplate/") + "Text" + ".cshtml");
      var regInfo = db.xyztables.Where(x => x.id == regid).FirstOrDefault();
      string regem = db.xyztables.Where(x => x.id == regid).Select(x => x.emailid).FirstOrDefault();
      var url = "http://xyz.com/" + "xyztables/Confirm?regem="+ regem;

      body = body.Replace("@ViewBag.ConfirmationLink", url);
      body = body.ToString();
      string from = "emailid";
      BuildEmailTemplate("Activate your Account", body, regInfo.emailid,from);

  }

  [HttpPost]

  public ActionResult Signup(string textbox1emailid, string textboxname, string textboxpass ,  string Create)
  {
      var checkdb = db.xyztables.Where(x => x.emailid == textbox1emailid).FirstOrDefault();
      if (checkdb == null)
      {
          xyztable table = new xyztable();
          xyztable.emailid = textbox1emailid.ToString();
          xyztable.name = textbox1name.ToString();
          xyztable.password = textbox1pass.ToString();
          xyztable.emailconfirmed = 0;
          db.xyztables.Add(xyztable);
          db.SaveChanges();
          sendemail4(xyztable.id);
          Session["check"] = "Please check your emailid to confirm your Account";
          return RedirectToAction("home");
      }
      else { Session["message"] = "Emailid already exists";
          return View("Signin");
      }
         }

解决方案

If it was working, and now it isn't, the issue is unlikely to be your code. It'll be a network\config\gmail issue. Google for the many issues you might face sending email through gmail as this is one of the most frequently asked question.

The "proper" answer is to not use gmail SMTP server at all, use the SMTP server provided by your network admin or your web host depending on where your code is running.
