ASP净MVC sendgrid帐户电子邮件验证 [英] asp net mvc sendgrid account email verification

问题描述

我试图发送自动发送邮件，用户完成注册，我测试我的应用程序的本地主机上

I'm trying to send automatic email to user to complete registration, I'm testing my app on local host

这是我的注册控制器：

// POST: /Account/Register
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
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)
        {
            //  Comment the following line to prevent log in until the user is confirmed.
            //  await SignInManager.SignInAsync(user, isPersistent:false, rememberBrowser:false);

            // For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=320771
            // Send an email with this link
            string code = await UserManager.GenerateEmailConfirmationTokenAsync(user.Id);
             var callbackUrl = Url.Action("ConfirmEmail", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
             await UserManager.SendEmailAsync(user.Id, "Confirm your account", "Please confirm your account by clicking <a href=\"" + callbackUrl + "\">here</a>");

            // Uncomment to debug locally 
            // TempData["ViewBagLink"] = callbackUrl;

            ViewBag.Message = "Check your email and confirm your account, you must be confirmed "
                            + "before you can log in.";

            return View("Info");
            //return RedirectToAction("Index", "Home");


        }
        AddErrors(result);
    }

    // If we got this far, something failed, redisplay form
    return View(model);
}

这是我的电子邮件服务类

this is my Email service class

 public class EmailService : IIdentityMessageService
{
    public async Task SendAsync(IdentityMessage message)
    {
        // Create the email object first, then add the properties.
        var myMessage = new SendGridMessage();

        // this defines email and name of the sender
        myMessage.From = new MailAddress("[e-mail]", "My Example Admin");

        // set where we are sending the email
        myMessage.AddTo(message.Destination);

        myMessage.Subject = message.Subject;

        // make sure all your messages are formatted as HTML
        myMessage.Html = message.Body;

        // Create credentials, specifying your SendGrid username and password.
        var credentials = new NetworkCredential(
             ConfigurationManager.AppSettings["SendGridLogin"],
             ConfigurationManager.AppSettings["SendGridPassword"]
                                                );

        // Create an Web transport for sending email.
        var transportWeb = new Web(credentials);

        // Send the email.
        await transportWeb.DeliverAsync(myMessage);
    }
}

我使用SendGridSmtpApi 1.3.1＆安培; SendGrid C＃cilent库6.3.4。
问题出在哪里，为什么不工作？

I'm using SendGridSmtpApi 1.3.1 & SendGrid C# cilent library 6.3.4 . Where is the problem , why this don't work ?

推荐答案

由于您正在异步调用，有可能你的程序是调用一个机会完成之前退出。因此，以下是必要的，如果你想阻止，直到通话结束，你的程序进行前：

Because you are making an asynchronous call, it is possible your program is exiting before the call a chance to complete. Therefore, the following is necessary if you would like to block until the call is complete, before your program proceeds:

transportWeb.DeliverAsync(message).Wait();

另外，你可以从调用函数取决于您期望的结果等待（）或结果。

Alternatively, you can "Wait() or Result" from the calling function depending on your desired result.
