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

问题描述

我正在使用典型的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/保存对话框打开，但.doc文件尝试在docs.google.com中打开，但由于缺少许可而失败 - 这是因为我正在从网站根外部提供文件。

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.

那么如何绕过docs.google并强制每个浏览器提供保存为对话框，无论文件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')

我尝试以下操作无效： 。/ p>

I tried the following to no avail:

1. in .htaccess file：

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');
