c# - UserManager SendEmailAsync 未发送电子邮件

Question

我正在使用以下代码尝试异步发送电子邮件，但没有发送任何电子邮件，我不确定哪里做错了。我还在 web.config 中为电子邮件协议(protocol)添加了第二段代码。

SendEmailAsync 代码

await UserManager.SendEmailAsync(username.Id, "MTSS-B: Forgot Password", "Here is your new password. Please go back to the MTSS-B web tool and sign in. You will be prompted to create your own password.<br/><br/>" + tmpPass + "<br/><br/>MTSS-B Administrator");

Web.config代码

<system.net>
<mailSettings>
  <smtp>
    <network host="smtp1.airws.org" userName="" password="" />
  </smtp>
</mailSettings>
</system.net>

****更新****

我测试了是否可以使用通常的方法发送电子邮件，并且可以使用以下代码发送电子邮件。

MailMessage m = new MailMessage(new MailAddress(ConfigurationManager.AppSettings["SupportEmailAddr"]), new MailAddress(model.Email));
m.Subject = "MTSS-B: Forgot Password"; 
m.Body = string.Format("Here is your new password. Please go back to the MTSS-B web tool and sign in. You will be prompted to create your own password.<br/><br/>Password: " + tmpPass + "<br/><br/>MTSS-B Administrator"); 
m.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient("smtp2.airws.org"); 
smtp.Send(m);

在您的应用程序中，App_Start 文件夹中可能有一个名为 IdentityConfig.cs 的文件。该文件的顶部可能有类似这样的内容:

public class EmailService : IIdentityMessageService
{
    public Task SendAsync(IdentityMessage message)
    {
        // Plug in your email service here to send an email.
        return Task.FromResult(0);
    }
}

将其更改为:

public class EmailService : IIdentityMessageService
{
    public Task SendAsync(IdentityMessage message)
    {
        SmtpClient client = new SmtpClient();
        return client.SendMailAsync(ConfigurationManager.AppSettings["SupportEmailAddr"], 
                                    message.Destination, 
                                    message.Subject, 
                                    message.Body);
    }
}

根据您的喜好自定义发送代码。
