Question

有很多关于如何在asp.net中启用帐户确认和密码恢复的教程，但是它们似乎都不适用于我。我尝试过使用SMTP但是没有用。我最后关注了asp.net建议的this教程。我也没有发现Stackoverflow上的任何答案都有用。

我在IdentifyConfig.cs中有以下课程，其中＆＃34; xxxxx＆＃34;用我的凭据代替。

    public class EmailService : IIdentityMessageService
    {
        public Task SendAsync(IdentityMessage message)
        {
            return configSendGridasync(message);
        }

        private Task configSendGridasync(IdentityMessage message)
        {
            var myMessage = new SendGridMessage();
            myMessage.AddTo(message.Destination);
            myMessage.From = new System.Net.Mail.MailAddress(
                                "xxxxxx", "xxxxxx");
            myMessage.Subject = message.Subject;
            myMessage.Text = message.Body;
            myMessage.Html = message.Body;

            var credentials = new NetworkCredential(
                       ConfigurationManager.AppSettings["xxxxxx"],
                       ConfigurationManager.AppSettings["xxxxxx"]
                       );

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

            // Send the email.
            if (transportWeb != null)
            {
                return transportWeb.DeliverAsync(myMessage);
            }
            else
            {
                return Task.FromResult(0);
            }
        }
    }

我已取消注释AccountController.cs中的代码，以启用电子邮件确认和密码恢复。
Register操作：

        public async Task<ActionResult> Register(RegisterViewModel model)
        {
            if (ModelState.IsValid)
            {
                var user = new ApplicationUser { UserName = model.Email, Email = model.Email, UserFirstName = model.UserFirstName, UserSurname = model.UserSurname };
                var result = await UserManager.CreateAsync(user, model.Password);
                if (result.Succeeded)
                {
                    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>");

                    return RedirectToAction("Index", "Home");
                }
                AddErrors(result);
            }

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

ForgotPassword行动

        public async Task<ActionResult> ForgotPassword(ForgotPasswordViewModel model)
        {
            if (ModelState.IsValid)
            {
                var user = await UserManager.FindByNameAsync(model.Email);
                if (user == null || !(await UserManager.IsEmailConfirmedAsync(user.Id)))
                {
                    // Don't reveal that the user does not exist or is not confirmed
                    return View("ForgotPasswordConfirmation");
                }

                // 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.GeneratePasswordResetTokenAsync(user.Id);
                var callbackUrl = Url.Action("ResetPassword", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);      
                await UserManager.SendEmailAsync(user.Id, "Reset Password", "Please reset your password by clicking <a href=\"" + callbackUrl + "\">here</a>");
                return RedirectToAction("ForgotPasswordConfirmation", "Account");
            }

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

我还为我的项目启用了SSL。

当我注册一个新用户时，它会加载一段时间，然后我收到以下错误：
Exceptions.InvalidApiRequestException: Bad Request Check 'Errors' for a list of errors returned by the API.

我的

await UserManager.SendEmailAsync(user.Id, "Confirm your account", "Please confirm your account by clicking <a href=\"" + callbackUrl + "\">here</a>");

Register发生了错误在AccountController.cs中找到的动作。

坦率地说，我不了解这个堆栈跟踪，因为我是asp.net的新手。结果，我不知道从哪里开始调试来追踪问题。

似乎是什么问题？

Answer 1

此时，我得出结论，SendGrid的C＃API非常有限，无法提供更详细的错误消息，或者允许优雅地处理错误。通过使用fiddler并查看服务器返回的消息，您可以更好地了解正在发生的事情。一旦你进入生产环境，所有的赌注都会被取消。祝你好运！

帐户确认和密码恢复不想使用SendGrid工作
