一旦将应用程序启动到Azure，则不会发送确认电子邮件.有人知道为什么吗

Question

你好，我在asp.net中创建了一个需要用户身份验证的应用程序。我已激活"电子邮件确认"选项。这在本地数据库中运行良好，但在azure上运行一次就不起作用了。电子邮件确认的代码如下：

public Task SendAsync(IdentityMessage message)
{

return Task.Factory.StartNew(() =>
{
sendMail(message);
});
}

void sendMail(IdentityMessage message)
{
#region formatter

string html =  message.Body;


#endregion
MailMessage msg = new MailMessage();
msg.From = new MailAddress(ConfigurationManager.AppSettings["Email"].ToString());
msg.To.Add(new MailAddress(message.Destination));
msg.Subject = message.Subject;

msg.AlternateViews.Add(AlternateView.CreateAlternateViewFromString(html, null, MediaTypeNames.Text.Html));
SmtpClient smtpClient = new SmtpClient("smtp-mail.outlook.com", Convert.ToInt32(587));
System.Net.NetworkCredential credentials = new System.Net.NetworkCredential(ConfigurationManager.AppSettings["Email"].ToString(), ConfigurationManager.AppSettings["Password"].ToString());
smtpClient.Credentials = credentials;
smtpClient.EnableSsl = true;
smtpClient.Send(msg);
}
}

我尝试了sendgrid，但似乎不起作用，所以我使用了outlook。

这是寄存器部分的代码：

public async Task<ActionResult> Register(RegisterViewModel model)
{
if (ModelState.IsValid)
{
var user = new ApplicationUser { UserName = model.Email, Email = model.Email };
var result = await UserManager.CreateAsync(user, model.Password);
if (result.Succeeded)
{                   
string callbackUrl = await SendEmailConfirmationTokenAsync(user.Id, "Confirm your account");                 
ViewBag.Message = "Check your email and confirm your account. You must confirm your email " + "before you can log in.";
return View("Info");
}
else 
{ return View("Error"); }
AddErrors(result);
}

最后是最后一部分的代码

private async Task<string> SendEmailConfirmationTokenAsync(string userID, string subject)
{
string code = await UserManager.GenerateEmailConfirmationTokenAsync(userID);
var callbackUrl = Url.Action("ConfirmEmail", "Account",
new { userId = userID, code = code }, protocol: Request.Url.Scheme);
await UserManager.SendEmailAsync(userID, subject,
"Please confirm your account by clicking <a href="" + callbackUrl + "">here</a>");
return callbackUrl;
}

当你的代码在Azure中运行时，它可能无法访问Outlook，这可以解释为什么没有发送电子邮件。

SendGrid是从Azure功能、web作业或任何应用程序发送电子邮件的推荐方法。关于如何使用SendGrid，这里有一个很好的解释：https://blog.mailtrap.io/azure-send-email/#What_do_I_need_to_send_emails_from_Azure

终于开始工作了。事实上，当我尝试它时，它以前是有效的，但确认进入了我的垃圾邮件文件夹。。。Doh。

public async Task SendAsync(IdentityMessage message)
{
// Plug in your email service here to send an email.
var apiKey = ConfigurationManager.AppSettings["SendGridAPI"];
var client = new SendGridClient(apiKey);
var from = new EmailAddress("your email address", "your name");
var subject = message.Subject;
var to = new EmailAddress(message.Destination);
var plainTextContent = message.Body;
var htmlContent = message.Body;
var msg = MailHelper.CreateSingleEmail(from, to, subject, plainTextContent, htmlContent);
var response = await client.SendEmailAsync(msg);

}
