Question

我正在尝试使用此脚本和swift邮件程序库自动将我的电子邮件转发到另一个帐户。事情似乎在某种程度上起作用，但附件是作为编码文本发送的。我想按原样发送附件。我是php的新手，无法找出问题所在。请帮我。

<?php
require_once 'lib/swift_required.php';
$hostname = '{imap.asd.com:993/imap/ssl}INBOX';
$username = 'abc@as.com';
$password = 'ppwppw';

/* try to connect */
$connection = imap_open($hostname,$username,$password) or die('Cannot connect to Tiriyo: ' . imap_last_error());

ini_set('memory_limit', '256M');

function Message_Parse($id)

Answer 1

$data = $result['attachments'];之后的$ data是什么？认为它是某种附件容器对象。您可能需要多挖一点才能获得正确的属性（附件）然后重新附加它。请参阅：http://dev.kayako.com/browse/SWIFT-2341

Answer 2

这看起来并不正确：

$data = $result['attachments'];
...
$attachment = Swift_Attachment::newInstance($data, 'recorded.mp3', 'audio/mp3');

使用此方法创建附件时，我认为$data应该是包含附件内容的字符串。但$result['attachments']是原始邮件中所有附件的数组。看起来你应该循环遍历这些附件，为每个附件创建一个单独的Swift_Attachment。您还应该保存原始消息中的文件名和内容类型，而不是将它们硬编码为recorded.mp3和audio / mp3（除非应用程序确保这一切都将存在）。

至于他们被编码 - MP3不是纯文本，所以你期待什么？

附件作为编码文本发送
