我正在使用Mailparse在MySQL数据库中解析和存储电子邮件。电子邮件直接通过管道传输到PHP脚本。超过99%的系统电子邮件都已正确解析。但是,我注意到有些电子邮件被截断了。问题似乎是消息的标题和正文之间的unicode字符......

This is a test ... the above "Det här är" chunk will be cut off at "Det h", and nothing else will arrive.
------=_NextPart_000_0018_01CFEC72.CE424470
以上内容将在标题之后被裁剪,所有到达的内容都是“Det h”。不知何故,非ascii字符(ü)导致mailparse在标题或多部分包装器之外时会发生阻塞。这可能是客户端正在使用的5年历史的Microsoft Windows Live Mail版本,搞乱标题等,但这不是理由,我需要能够接收它。
我正在运行PHP 5.4.30,它在php.ini中有default_charset = "utf-8"
。但我注意到phpinfo()
默认有mailparse.def_charset = "us-ascii"
,即使php.ini中没有配置它。添加该行并将其设置为“utf8”后,phpinfo()
正确显示了utf-8。但是错误仍然存在。我没有想法。
有关如何处理此错误的任何建议?
答案 0 :(得分:3)
我在评论中提到的一个想法......这部分与消息部分有关。如果由于某种原因,解码失败,则“按原样”返回内容。您可以尝试根据$headers['transfer-encoding'];
解码它或保持不变。 $email
是包含标题的完整邮件来源。 $section
是通过mailparse_msg_get_part
(手动,示例,Google)获取的数据
$headers = mailparse_msg_get_part_data($section);
$content = '';
set_error_handler(function() use(&$content, $headers, $email){
$start = $headers['starting-pos-body'];
$end = $headers['ending-pos-body'];
$content = substr($email, $start, $end - $start);
});
ob_start();
mailparse_msg_extract_part($section, $email);
$body = ob_get_clean();
restore_error_handler();
if (!empty($content)) $body = $content;
结果(经过一些操作,因为我只留下了我真正需要的标题)
["charset"]=> string(5) "utf-8" ["content-charset"]=> string(5) "utf-8" ["content-type"]=> string(10) "text/plain" ["content"]=> string(108) "This is a test ... the above "Det här är" chunk will be cut off at "Det h", and nothing else will arrive. "
