我有一个向用户发送电子邮件的代码。在电子邮件中，有一个链接，他们应该访问相应的ID，以便将它们定向到某个页面。
这是我的代码：
public class DialogueFactory implements VoiceXmlDialogueFactory {
@Override
public VoiceXmlDialogue create(
DialogueInitializationInfo<VoiceXmlInputTurn, VoiceXmlOutputTurn, VoiceXmlDialogueContext> initializationInfo)
throws DialogueFactoryException {
if (!(initializationInfo instanceof WebDialogueInitializationInfo))
throw new DialogueFactoryException("Can only work in web mode.");
WebDialogueInitializationInfo<?, ?, ?> webInitializationInfo =
(WebDialogueInitializationInfo<?, ?, ?>) initializationInfo;
String dialogueType = webInitializationInfo.getHttpServletRequest().getParameter("type");
// Then use dialogueType to build the right kind of Dialogue.
}
}
在这一行：public void Notify(int appr_id = 0)
{
var check = db.rms_approval_routing.Where(s => s.appr_id == appr_id && s.appr_isactive == true).FirstOrDefault();
try
{
if (check != null)
{
check.status_id = 8;
db.Entry(check).State = EntityState.Modified;
db.SaveChanges();
var getinfo = db.rms_approval_route_vw.Where(s => s.appr_id == appr_id && s.appr_isactive == true).FirstOrDefault();
var getpayment = db.rms_payment.Where(s => s.appr_id == appr_id).FirstOrDefault();
if (getinfo != null && getpayment != null)
{
var ref_email = getinfo.ref_email;
var cc_email = getinfo.user_email;
var pay = getpayment.p_amount;
var body = "";
body = "Good day!<br><br>Please be informed that you have successfully referred <u>" + getinfo.Fullname + "</u> and you are entitled to receive <u>P " + pay + "</u> which will be credited on the next payout for your successful referral.<br>Kindly visit the link to acknowledge the payment: http://localhost:8119/ReferralLetter/Acknowledge/" + appr_id + " <br>Thanks!";
SendEmailController email = new SendEmailController();
email.SendReferrer(ref_email, cc_email, body);
}
}
}
catch (Exception)
{
throw;
}
}
public ActionResult Acknowledge(int appr_id = 0)
{
var check = db.rms_emails.Where(s => s.appr_id == appr_id && s.email_date_ack == null && s.email_isactive == true).FirstOrDefault();
if (check != null) {
ViewBag.email_id = check.email_id;
ViewBag.appr_id = appr_id;
return PartialView();
}
return RedirectToAction("Denied");
}
当我尝试断开http://localhost:8119/ReferralLetter/Acknowledge/" + appr_id函数时，appr_id值为0。当我收到电子邮件时，它显示了这一行：Acknowledge
意味着那里有一个ID，但为什么在http://localhost:8119/ReferralLetter/Acknowledge/23函数中ID为0？
