如何通过asp.net web api发送电子邮件

Question

我正在制作一个 Windows Phone 应用程序，我想在其中提供忘记密码的功能。 当用户按下忘记密码按钮时，该应用程序将向用户存储的电子邮件 ID 发送一封电子邮件。 由于 windows phone 中没有可用的 smtp 类，所以我想制作一个 asp.net web api，它将从应用程序接收电子邮件 ID（和密码）并向该 ID 发送电子邮件。 我是 Web 服务的新手，对此知之甚少 请指导我如何完成这项任务，如果有人可以提供代码，那么一定有一些这样的网络服务可用。

Answer 1

这是一个发送电子邮件的功能示例，您可以使用它。此外，下面有几个链接可以指导您在 ASP.NET 中创建 Web 服务

实际上，您不需要为此创建 Web 服务（尽管建议这样做）。您可以创建一个快速而肮脏的 Web 表单，您可以在其中传递像这样的参数 example.com/sendemail.aspx?account=jack.smith&id=223232343

private static void SendEmail(string from, string from_name, string to, string cc, string bcc, string subject, string body, bool isHtml)
{
    SmtpClient mailClient = new SmtpClient(Config.SmptSettings.Server);
    mailClient.Credentials = new NetworkCredential(Config.SmptSettings.UserName, Config.SmptSettings.Password);
    mailClient.Port = Config.SmptSettings.Port;

    MailMessage message = new MailMessage();
    if (!string.IsNullOrEmpty(from_name))
    {
        message.From = new MailAddress(from, from_name);
    }
    else
    {
        message.From = new MailAddress(Formatter.UnFormatSqlInput(from));
    }

    message.To.Add(new MailAddress(to));

    if (!string.IsNullOrEmpty(bcc, cc))
    {
        message.CC.Add(cc);
        message.Bcc.Add(bcc);
    }

    message.Subject = subject;
    message.Body = body;
    message.IsBodyHtml = isHtml;

    mailClient.EnableSsl = Config.SmptSettings.SSL;
    mailClient.Send(message); 
}

 ## Call this function in your WebApi controller ##

    private void sendEmailViaWebApi()
    {
                string subject = "Email Subject";
                string body = "Email body";
                string FromMail = "shahid@reckonbits.com.pk";
            string emailTo = "reciever@reckonbits.com.pk";
                MailMessage mail = new MailMessage();
                SmtpClient SmtpServer = new SmtpClient("mail.reckonbits.com.pk");

                mail.From = new MailAddress(FromMail);
                mail.To.Add(emailTo);
                mail.Subject = subject;
                mail.Body = body;

                SmtpServer.Port = 25; 
                SmtpServer.Credentials = new System.Net.NetworkCredential("shahid@reckonbits.com.pk", "your password");
                SmtpServer.EnableSsl = false;
                SmtpServer.Send(mail);
    }

对于使用 .NET Core 的用户，请注意目前不支持发送电子邮件。

通过 GitHub 查看 .NET Core 的以下问题： https://github.com/dotnet/corefx/issues/1006

已经实施了另一种解决方案 - MailKit： https://github.com/jstedfast/MailKit
