使用 <filesMatch> 强制下载在 htaccess 中 [英] Forcing a download using &lt;filesMatch&gt; in htaccess

问题描述

我正在尝试强制下载一个文件夹中的所有文件.

I'm trying to force the download of all files of one folder.

页面上的链接是这样的

<a href="http://example.com/uploads/documents/file.pdf">Click to download</a>

我的 .htaccess 中有这个片段

And I have this snippet in my .htaccess

<filesMatch ".*uploads/documents.*">
    ForceType application/octet-stream
    Header set Content-Disposition attachment
</filesMatch>

我已经知道标签内的 2 行是有效的，因为当我将 .htaccess 直接放在我想使用以下代码强制下载的文件夹中时它有效:

I already know that the 2 lines inside the tag works, because it works when I put a .htaccess directly inside the folder where I want to force the download with the following code:

<Files *.*>
    ForceType application/octet-stream
    Header set Content-Disposition attachment
</Files>

我似乎不了解 filesMatch 标签.

There seems to be something which I don't understand about the filesMatch tag.

推荐答案

请查看 FilesMatch 和 文件， 分别.它明确指出

Please look at the documentation for FilesMatch and Files, respectively. It clearly states

本节中给出的指令将应用于任何对象具有与指定的匹配的基本名称(文件名的最后一个组成部分)文件名.

The directives given within this section will be applied to any object with a basename (last component of filename) matching the specified filename.

这意味着在您的示例中，它与 file.pdf 匹配.您的第二个示例 *.* 匹配 file.pdf，但是您的第一个示例 .*uploads/documents.* 不匹配.它实际上永远无法匹配，因为它包含一个斜杠，用作目录分隔符.

That means that in your example it matches against file.pdf. Your second example *.* matches file.pdf, however your first example .*uploads/documents.* does not. It actually can never match, since it contains a slash, which is used as a directory separator.

您应该将 或 (取决于您要强制下载的内容)包含在 Location 指令:

You should enclose either <Files *.*> or <Files *.pdf> (depending on what you want to enforce downloading) in a Location directive:

<Location "/uploads/documents/">
    <Files *.*>
        ForceType application/octet-stream
        Header set Content-Disposition attachment
    </Files>
</Location>

如果您无法编辑 apache 配置

不幸的是，在 .htaccess 文件中不允许使用 Location 指令.只需在 /uploads/documents/ 目录中创建一个 .htaccess.

If you cannot edit the apache config

Unfortunately, the Location directive is not allowed inside .htaccess files. Just create a .htaccess inside your /uploads/documents/ directory.
