Question

我正在寻找一种使用ajax和c＃mvc从我的邮件列表中退订客户端的方法。

我试图在我的.js文件中使用$（document）.ready（function（）...函数）来获取隐藏在我的Index.cshtml文件的输入元素中的查询字符串值，该字符串将首先显示用户点击电子邮件中的“取消订阅”后，加载正确后，这会将用户记录更新为取消订阅。

Index.cshtml文件上的输入元素

<input type="hidden" value='@Request.QueryString["email"]' id="QryEmailAddress" />

.js文件中的Ajax代码

$(document).ready(function () {
    var emailAddress = $("#QryEmailAddress").val();

    if (emailAddress != null || emailAddress != "") {
        $.ajax({
            type: "POST",
            url: '/Home/UnsubscribeClientEmail',
            data: { emailAddress: emailAddress },
            beforeSend: function () {
                $('#LoadingBoxModal #showProgress').html();
                $('#LoadingBoxModal .modal-dialog').css('width', '');
                $('#LoadingBoxModal').appendTo('body');
                $('#LoadingBoxModal').modal({
                    backdrop: 'static',
                    keyboard: false,
                    show: true
                });
            },
            success: function (data) {
                $("#LoadingBoxModal").modal('hide');
            },
            error: function (error) {
                $("#LoadingBoxModal").modal('hide');
            },
            completed: function () {
                $("#LoadingBoxModal").modal('hide');
            }
        });
    }
    else {
        //If there's no value, then continue going opening a home page as usual...
    }
});

如果上面代码中的emailAddress变量中包含一个值，它将进入我的HomeController.cs文件中的代码中。

public string UnsubscribeClientEmail(string email)
{
   var _updateClientInfo = new HomeTransactions(new PetaConnection().db()).ClientSubscriptions(email);
   return _updateClientInfo;
}

.home控制器中的ClientSubscriptions（email）引用以下代码。

public string ClientSubscriptions(string emailAddress)
{
   var _getClientInfo = _connect.FirstOrDefault<ClientInfo>($"select  * from ClientInfo where EmailAddress = '{emailAddress}'");
   _getClientInfo.EmailSubscription = "No";
   _getClientInfo.DateUpdated = DateTime.Now;
   _connect.Update(_getClientInfo);
   return "OK";
}

这是发送给客户端的电子邮件功能。

public void SendNotification(string emailAddress, string firstName, string referenceNo)
{
   string adminName = "Company Name";
   string adminAddress = "admin@domain.com";
   string password = "Jibbirish";
   string serverAddress = "aserv.domain.com";
   try
   {
        SmtpMail smtpMail = new SmtpMail("TryIt");
        SmtpClient smtpClient = new SmtpClient();

        smtpMail.From = new MailAddress(adminName, adminAddress);
        smtpMail.To = emailAddress;
        smtpMail.Subject = "Subject";
        smtpMail.Priority = MailPriority.High;
        SmtpServer smtpServer = new SmtpServer(serverAddress);
        smtpServer.User = adminAddress;
        smtpServer.Password = password;

       Attachment attachment = smtpMail.AddAttachment("C:\\images\\Logo_Full.jpg");

       string contentId = "myLogo";
       attachment.ContentID = contentId;
       smtpMail.HtmlBody = "<html><body><a href='.../Home/Index?email=" + emailAddress + "'>Unsubscribe</a></body></html>";
       SmtpClientAsyncResult asyncResult = smtpClient.BeginSendMail(smtpServer, smtpMail, null, null);
       //Waiting to send email...
       while (!asyncResult.IsCompleted)
       {
          asyncResult.AsyncWaitHandle.WaitOne(10, false);
       }
       smtpClient.EndSendMail(asyncResult);
  }
  catch (Exception ex)
  {
      throw;
  }
}

当用户单击电子邮件中的“取消订阅”时，一旦他们登陆我们的网站，他们就会收到一条消息，告知他们结果...
