从内unity3d发送电子邮件 [英] Sending email from inside unity3d

问题描述

我想从内统一使用的SmtpClient类智能手机发送电子邮件。我已经实现了这个非常简单的任务，在iOS上，但完全相同的code不能在Android的工作。这里的code：

I am trying to send an email from inside unity on smartphones using the SmtpClient class. I have achieved this quite simple task on iOS but the exact same code does not work on android. Here's the code:

private IEnumerator sendAutoMail (string textBody,string title)
{
    MailMessage mail = new MailMessage();
    mail.From = new MailAddress(sender);
    mail.To.Add(receiver);
    mail.Subject = "R4UL " + title;
    mail.Body = textBody;

    Debug.Log("Connecting to SMTP server");
    SmtpClient smtpServer = new SmtpClient("smtp.gmail.com");
    smtpServer.Port = 587;
    smtpServer.Credentials = new System.Net.NetworkCredential(sender, password) as ICredentialsByHost;
    smtpServer.EnableSsl = true;
    ServicePointManager.ServerCertificateValidationCallback = delegate(object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
    {
        return true;
    };
    Debug.Log("Sending message");
    smtpServer.Send(mail);
    yield return null;
}

如果发件人，密码和接收器是我的Gmail帐户，我的Gmail密码和人，我想分别以发送电子邮件。

Where sender, password and receiver are my Gmail account, my Gmail password and the person I wish to email respectively.

所以这完美的作品在iOS，但Android上引发以下错误：

So this works perfectly on iOS but on android throws the following error:

I /统一（6256）：SocketException：没有这样的主机被称为I /统一（6256）：在System.Net.Dns.GetHostByName（System.String主机名）[0 X00000]：0 I /统一（6256 ）：在System.Net.Dns.GetHostEntry（System.String hostNameOrAdd RESS）[0x00000]中：0 I /统一（6256）：在System.Net.Dns.GetHostAddresses（System.String hostNameO rAddress）[0x00000]在： 0 I /统一（6256）：在System.Net.Sockets.TcpClient.Connect（System.String主机名，端口的Int32）[0x00000]中：0 I /统一（6256）：在System.Net.Sockets.TcpClient。 .ctor（System.String hostna我的Int32端口）[0x00000]中：0 I /统一（6256）：在System.Net.Mail.SmtpClient.SendInternal（System.Net.Mail .MailMessage消息）[0x00000]在： 0 I /统一（6256）：在System.Net.Mail.SmtpClient.Send（System.Net.Mail.MailMes圣人消息）[0x00000]中：0 I /统一（6256）：重新抛出的SmtpException：邮件无法发送。 I /统一（6256）：在System.Net.Mail.SmtpClient.Send（System.Net.Mail.MailMes圣人消息）[0x00000]中：0 I /统一（6256）：在FeedbackSender + c__Iterator1.MoveNext（）

我已成功地pintpoint在该行的错误位置： smtpServer.Send（邮件）;

I have managed to pintpoint the error location at the line: smtpServer.Send(mail);

任何想法，什么可能会造成这个问题？我同时拥有Android和iOS专业版。

Any ideas as to what might be causing this issue? I have both android and iOS pro versions.

干杯

推荐答案

原来我送SMTPClient对象到不同的方法，然后尝试使用对象发送邮件。这是因为它停止尽快抛出一个错误，因为该方法创建了自己的SMTPClient对象是什么原因导致的错误。

Turns out I was sending the SMTPClient object to a different method which was then trying to send a mail using that object. This is what was causing the error as it stopped throwing an error as soon as that method created its own SMTPClient object.
