从Javascript返回具有Content-type的文件内容

Question

I'm trying to include a vCard in a Weebly website, but I need to return the Content-type header, so a simple attachment won't work. I have found the following code in PHP to do this, but I can't include PHP code on Weebly, only Javascript:

<?php
    header("Content-type: text/x-vcard");
    header("Content-Disposition: attachment; filename=\"contact.vcf\";");
    echo file_get_contents("contact.vcf");
?>

Is there a way to include a button that would return this in Javascript?

Answer 1

您应该能够将其添加到简单的锚标记中，然后浏览器将对其进行处理。

<a href="contact.vcf">My Contact</a>
