Question

这是我在IdentityConfig.cs文件中的简单EmailService类。

public class EmailService : IIdentityMessageService
{
    public Task SendAsync(IdentityMessage message)
    {
        // Plug in your email service here to send an email.
        // return Task.FromResult(0);
        const string userName = "ashish_qluto";
        const string from = "akanksha16296@gmail.com";
        const string password = "xxxxxx";
        //const int port = 587;

        var smtpClient = new SmtpClient("smtp.sendgrid.net", Convert.ToInt32(587));

        smtpClient.Port = 587;
        // smtpClient.ServicePoint.MaxIdleTime = 1;
        smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
        smtpClient.UseDefaultCredentials = false;

        // smtpClient.Credentials = new NetworkCredential(userName, password);
        NetworkCredential credentials = new NetworkCredential(userName, password);
        smtpClient.EnableSsl = true;
        smtpClient.Credentials = credentials;

        var mailMessage = new MailMessage(from, message.Destination);
        mailMessage.Subject = message.Subject;
        mailMessage.Body = message.Body;

        return smtpClient.SendMailAsync(mailMessage);
    }
}

这是我的Register方法的POST版本，我试图在注册成功后发送电子邮件链接。

[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)
        {
            var 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 this link:");
            //ViewBag.Link = callbackUrl;
            return View("CheckYourEmail");
        }
        AddErrors(result);
    }

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

我见过许多与邮件发送有关的文章。我在web.config文件中没有配置任何内容。我在这两个类中简单地对所有内容进行了硬编码。

我只使用UserName而不是gmail帐户名。
我已注册SendGrid免费帐户。我已经在任何需要的地方正确放置了用户名和密码以及电子邮件帐户名称。
我在本地主机上测试了这个。我读到某处不在本地主机上部署。试试外部服务器。我也已部署。
我在Windows Azure上配置了免费的SendGrid帐户。我已经浪费了一整天来搞清楚它并尝试了多种选择。我得到的错误是 -

我已根据SSL的SendGrid文档中的建议将端口号从527更改为465。现在，我得到以下错误--- 异常详细信息：System.Net.Mail.SmtpException：语法错误，命令无法识别。服务器响应是：导致错误的行是---

  var callbackUrl = Url.Action("ConfirmEmail","Account",new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
       /// this function SendEmailAsync is causing Syntax error
        await UserManager.SendEmailAsync(user.Id,"Confirm your account","Please confirm your account by clicking <a href=\"" + callbackUrl + "\">here</a>");

        return View("CheckYourEmail");

Answer 1

const string userName = "ashish_qluto";

需要。。

const string userName = "apikey";

输入密码...

const string password = "xxxxxx";  // xxxxxx = sendgrid api key
