如何在我从Perl CGI脚本发送的HTML电子邮件中包含CSS文件？

Question

I am using following code to create and send email through CGI perl. The images get attached properly, but the css files do not.

  my $msg = new MIME::Lite(
            From    => $from,
            To      => $to_list,
            Subject => "My subject",
            Type    => 'text/html',  # 'multipart/mixed'
            Data    => $body
           );
 $msg->attach(Type => 'multipart/mixed',      Path => $DOCS_URL . "/fonts-min.css");
 $msg->attach(Type => 'multipart/mixed',      Path => $DOCS_URL . "/eat.css");
 $msg->attach(Type => 'multipart/mixed',      Path => $DOCS_URL . "/site_styles2.css");
 $msg->attach(Type => 'multipart/mixed',      Path => $DOCS_URL . "/calendar_layout.css");
 $msg->attach(Type => 'multipart/mixed',      Path => $DOCS_URL . "/errnacc.css");
 $msg->attach(Type => 'image/png',    Path => $DOCS_URL . "/separator.gif");
 $msg->attach(Type => 'image/png',    Path => $DOCS_URL . "/trans_pixel.gif");
 $msg->attach(Type => 'image/png',    Path => $DOCS_URL . "/itg_side.gif");

 $msg->send();

The images get attached properly, but the css files are not attached at all. Any idea what 'Type' should be used to attach CSS files? Or is there any other problem?

Answer 1

我相信text / css应该没问题

From my tests, many email clients simply remove all the head elements before displaying an email message. Therefore, using external style sheets isn't feasible if you have to support a wide range of email clients.

My advice is to include styling directly into the HTML, as painful as that is.

I have to say, if what you're trying to do with your script is send HTML-formatted email, even if you get the CSS files sent as attachments, it's not going to work.

The only way to do this with any confidence at all is to send HTML with all external files linked using absolute URLs. And even then it won't work the way you expect it to.

尝试使用内联css ...它的工作原理（参见http://www.tizag.com/cssT/inline.php ）

我认为你已经得到了你的答案，但在我看来，好的方法是，不是直接输入HTML代码，而是使用一些基于html的邮件信封，在单独的html文件中包含消息和占位符，然后解析并替换占位符，以便您可以轻松地使用CSS我认为这也很容易维护。
