强制浏览器下载文件而不是打开文件 [英] Force browsers to download a file rather than open

问题描述

我使用典型的 PHP 代码下载文档:

I'm using typical PHP code to download documents:

  header('Content-Type: ' . $mimeTypes[$fileext]); 
  header('Content-Disposition: attachment; filename="' . $filename . '"');
  header('Content-Transfer-Encoding: binary');
  header('Accept-Ranges: bytes');
  header('Cache-Control: private');
  header('Pragma: private');

  readfile($filepath);

一切正常 - 下载/另存为对话框打开，除了尝试在 docs.google.com 中打开但由于缺乏权限而失败的 .doc 文件 - 那是因为我从外部提供文件网站根.

Everything works fine - a download/save-as dialog opens, except for .doc files which attempt to open in docs.google.com but they fail due to lack of permission - that's because I'm serving files from outside a website root.

那么我如何绕过 docs.google 并强制每个浏览器提供另存为对话框，而不管文件 mime 类型如何?('doc' => 'application/msword')

So how do I bypass docs.google and force every browser to offer save-as dialog regardless of the file mime type? ('doc' => 'application/msword')

我尝试了以下方法无济于事:

I tried the following to no avail:

1. 在 .htaccess 文件中:

1. in .htaccess file:

<FilesMatch ".(?i:doc)$">
    ForceType application/octet-stream
    Header set Content-Disposition attachment
</FilesMatch>

在 .htaccess 文件中:

in .htaccess file:

AddType application/octet-stream .doc

在 PHP 脚本中:

in PHP script:

header('Content-Type: application/force-download');

推荐答案

将此添加到您的标题:

header("Content-type: application/force-download");
