在Apache htaccess中有条件地设置标头 [英] Conditionally set headers in Apache htaccess

问题描述

我有一个PHP Laravel应用程序，带有标准的 .htaccess 文件，如下所示。

I have a PHP Laravel application with a standard .htaccess file as follows.

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    RewriteEngine On

    # Redirect Trailing Slashes If Not A Folder...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)/$ /$1 [L,R=301]

    # Handle Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]
</IfModule>

如果请求的URL映射到静态文件，则将其提供，否则 index.php 被调用。我需要为静态文件添加一组标题，这将是上述最后两个条件的其他。我需要类似下面的伪代码。

If the requested URL maps to a static file, it is served, and otherwise index.php is invoked. I need to add a set of headers for static files, which would kind of be the "else" of the last two conditions above. I need something like the below pseudo.

if static file
    Header set MyHeaderOne "something"
    Header set MyHeaderTwo "something"
end if

设置MyHeaderTwo something
结尾我可以添加标题了，但是得到了坚持有条件地这样做。我看了一下 SetEnvIf ，这可能使之成为可能。

I can add the headers just fine, but got stuck at doing so conditionally. I looked a bit at SetEnvIf, which may make it possible.

所以，我如何只添加一些标题对于静态文件，即是否存在请求的文件（例如 /images/example.jpg ）？

So, how can I add some headers only for static files, i.e. if the requested file exists (e.g. /images/example.jpg)? Thanks a lot in advance!

推荐答案

您可以执行条件声明，就像您所说的一样。

You can do a condition statement just like what you stated.

<If "%{REQUEST_URI} =~ /\.(gif|jpe?g|png|css|js)$/">
  #put your header set stuff here
</If>
