问题描述
我似乎无法在Laravel 4 docs/Email API中找到可以在电子邮件中添加自定义标头的方法.
I can't seem to locate the method within the Laravel 4 docs/Email API where I can add custom headers to an email.
例如:
Mail::send('emails.welcome', $data, function($message)
{
$message->to('[email protected]', 'John Smith')->subject('Welcome!');
$message->headers('X-Tags', 'tag1 tag2 tag3');
});
有人知道该怎么做吗?
推荐答案
据我所知，如果不进入Swift Mailer，就无法添加自定义标头.
As far as I know there's no way to add custom headers without reaching in to Swift Mailer.
尝试这样的事情.
$message->getSwiftMessage()->getHeaders()->addTextHeader('X-Tags', 'tag1 tag2 tag3');
它看起来并不漂亮，但是通过寻找应该解决问题的源代码来解决.
It doesn't look pretty but from looking through the source that should do the trick.
正如下面的注释所指出的，由于我忽略了Illuminate\Mail\Message类上的__call魔术方法，因此不需要getSwiftMessage方法.
As pointed out in the comments below the getSwiftMessage method isn't required as there is an __call magic method on the Illuminate\Mail\Message class that I overlooked.
$message->getHeaders()->addTextHeader('X-Tags', 'tag1 tag2 tag3');
