使用Gmail新API发送包含附件的邮件,但不会显示在收件箱的收件箱中
问题描述:
我们正在整合GMail,使用它们提供的最新API作为我们应用程序中开发电子邮件客户端的一部分。我们正在使用Google提供的PHP客户端库。使用Gmail新API发送包含附件的邮件,但不会显示在收件箱的收件箱中
见链接https://developers.google.com/api-client-library/php/
在此我试图发送邮件带有附件。这里我们已经生成了message/rfc822兼容文本,并通过'raw'参数传递它。这里我发现的问题是,在执行代码之后,当我检查通过GMail API发送的邮件的发送邮件时,附件显示正确。但是没有收到/显示发件人的邮箱。
看到代码的详细信息:

}
return $recipient;

请帮我... 在此先感谢。
答
替换您:
$strRawMessage .= 'Content-type: Multipart/Alternative; boundary="' . $boundary . '"' . "\r\n";
有:
$strRawMessage .= 'Content-type: Multipart/Mixed; boundary="' . $boundary . '"' . "\r\n";
您检查垃圾邮件文件夹?由于标题数据错误,我遇到了一些电子邮件问题 – Bowdzone 2014-10-29 10:23:27
它正在收件人的收件箱中,但没有附件。你有使用PHP中的GMail API发送邮件的正常工作代码示例吗? – 2014-10-29 12:04:48
你的代码对我来说工作得很好。我可以在发送的邮件文件夹和收件箱中看到附件。我像你一样使用了csv附件。某种程度上你的文件损坏了吗?你可以使用不同的CSV再试一次吗? – 2014-11-06 19:49:39
