如何在 zf2 中发送包含 text/plain、text/html 和附件的电子邮件？
我使用此代码通过 smtp 发送电子邮件：
$files = $this->params()->fromFiles();
$smtp = new \Zend\Mail\Transport\Smtp();
$smtp->setAutoDisconnect(true);
$optn = new \Zend\Mail\Transport\SmtpOptions(array(
'host' => 'mail.myserver.com',
'connection_class' => 'login',
'connection_config' => array(
'username' => '[email protected] /cdn-cgi/l/email-protection',
'password' => 'mypassword',
),
));
$smtp->setOptions($optn);
$htmlPart = new \Zend\Mime\Part('<p>some html</p>');
$htmlPart->type = Mime::TYPE_HTML;
$textPart = new \Zend\Mime\Part('some text');
$textPart->type = Mime::TYPE_TEXT;
$i=0;
$attaches = array();
foreach($files as $file){
if ($file['error'])
continue;
$attaches[$i] = new \Zend\Mime\Part(file_get_contents($file['tmp_name']));
$attaches[$i]->type = $file['type'].'; name="'.$file['name'].'"';
$attaches[$i]->encoding = 'base64';
$attaches[$i]->disposition = 'attachment';
$attaches[$i]->filename = $file['name'];
$i++;
}
$parts = array();
if (count($attaches)>0) {
$parts = array_merge(array($textPart,$htmlPart),$attaches);
$type = Mime::MULTIPART_MIXED;
}
else{
$parts = array($textPart, $htmlPart);
$type = Mime::MULTIPART_ALTERNATIVE ;
}
$body = new \Zend\Mime\Message();
$body->setParts($parts);
$message = new \Zend\Mail\Message();
$message->setFrom('[email protected] /cdn-cgi/l/email-protection');
$message->addTo('[email protected] /cdn-cgi/l/email-protection');
$message->setSubject('subject');
$message->setEncoding("UTF-8");
$message->setBody($body);
$message->getHeaders()->get('content-type')->setType($type);
$smtp->send($message);
如果我附加文件，它会发送文件和内容，但会在接收者收件箱中同时显示纯文本和 html 文本：
<p>some html</p>
some text
当我不附加任何文件时，它单独显示 html 文本：
some html
有什么帮助吗？
目前，ZF2 (2.2) 中没有简单的方法将多部分/替代正文（对于不能/不想使用 html 的客户来说，带有文本替代的 html）与附件相结合。
如果您将“multipart/alternative”内容类型标头添加到整封邮件中，则在某些电子邮件客户端中将不会显示附件（链接）。
解决方案是将消息分成两部分：正文（文本和 html）和附件：

一个例子：
$content = new MimeMessage();
$htmlPart = new MimePart("<html><body><p>Sorry,</p><p>I'm going to be late today!</p></body></html>");
$htmlPart->type = 'text/html';
$textPart = new MimePart("Sorry, I'm going to be late today!");
$textPart->type = 'text/plain';
$content->setParts(array($textPart, $htmlPart));
$contentPart = new MimePart($content->generateMessage());
$contentPart->type = 'multipart/alternative;' . PHP_EOL . ' boundary="' . $content->getMime()->boundary() . '"';
$attachment = new MimePart(fopen('/path/to/test.pdf', 'r'));
$attachment->type = 'application/pdf';
$attachment->encoding = Mime::ENCODING_BASE64;
$attachment->disposition = Mime::DISPOSITION_ATTACHMENT;
$body = new MimeMessage();
$body->setParts(array($contentPart, $attachment));
$message = new Message();
$message->setEncoding('utf-8')
->addTo('[email protected] /cdn-cgi/l/email-protection')
->addFrom('[email protected] /cdn-cgi/l/email-protection')
->setSubject('will be late')
->setBody($body);
$transport = new SmtpTransport();
$options = new SmtpOptions($transportConfig),
));
$transport->setOptions($options);
$transport->send($message);
对于上述内容，您需要以下使用语句：
use Zend\Mail\Message;
use Zend\Mail\Transport\Smtp as SmtpTransport;
use Zend\Mail\Transport\SmtpOptions;
use Zend\Mime\Mime;
use Zend\Mime\Part as MimePart;
use Zend\Mime\Message as MimeMessage;
ZF1 有一个_buildBody()中的方法Zend_Mail_Transport_Abstract它自动执行了此操作。
