如何通過ASP.NET Web API發送電子郵件

Question

我正在制作Windows Phone應用程序，希望在其中提供忘記密碼功能。 當用戶按下“忘記密碼”按鈕時，該應用程序將向用戶存儲的電子郵件ID發送一封電子郵件。 由於Windows Phone中沒有可用的smtp類，因此我想制作一個asp.net Web API，它將從應用程序接收電子郵件ID（和密碼），並將電子郵件發送給該ID。 我是Web服務的新手，對此有0的知識，請指導我如何完成此任務，如果任何人都可以提供代碼，則必須有一些可用的Web服務。

Answer 1

這是發送可以使用的電子郵件的功能的示例。 另外，下面有幾個鏈接可以指導您在ASP.NET中創建Web服務

實際上，您無需為此創建Web服務（盡管建議這樣做）。 您可以創建一個快速且骯臟的Web表單，在其中傳遞諸如example.com/sendemail.aspx?account=jack.smith&id=223232343這樣的參數

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);
    }

對於使用.NET Core的用戶，請注意，當前不支持發送電子郵件。

通過GitHub看到有關.NET Core的以下問題： https : //github.com/dotnet/corefx/issues/1006

已經實現了一個替代解決方案-MailKit： https ： //github.com/jstedfast/MailKit
