如何处理获取请求在php中抛出mp3文件

Consider this url: http://example.com/file.mp3?hash=ajhfsjdhfjksf546sdf

So, my question is that how can i handle this get request?

To determine whether this hash is allowed to download or not?

    In my comment on your questions I suggested:

    You could use Apache's mod_rewrite to create a rule that sees something like file.mp3?hash=ajhfsjdhfjksf546sdf and redirects it to file.php?file=file.mp3&hash=ajhfsjdhfjksf546sdf. Then file.php will be able to handle the logic of checking access.

    Here is the code for .htaccess to accomplish this:

    RewriteCond %{QUERY_STRING} hash=(.*)$
    RewriteRule ^(.*)\.mp3$ file.php?file=$1.mp3&hash=%1 [L]
    

    This looks for a hash= value in the query string, and matches any called to (something).mp3. It snags the (something) and passes it as a value to the PHP script.

    Now if I call file.mp3?hash=ajhfsjdhfjksf546sdf, then file.php will have the following set:

    $_GET['file'] == 'file.mp3'
    $_GET['hash'] == 'ajhfsjdhfjksf546sdf'
    

    With these values, you can now run whatever check you'd like, and if it pases, deliver file.mp3 to the client.
