我在ASP.NET MVC中使用电子邮件验证但它不起作用？

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）; 
} 
}

           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");
       }

      body = body.ToString();
      string from = "emailid";
      BuildEmailTemplate("Activate your Account", body, regInfo.emailid,from);
