在mediawiki中，如果上傳doc或者docx文件時，經常會出現：文件擴展名".***" 與檢測到的文件MIME類型(application/zip)不匹配 的警告。要想去掉這個警告，需要更改includes目錄下的DefaultSettings.php文件，其中的 $wgVerifyMimeType = false， 即可。
本內容取自mediawiki官方文檔。原文內容如下：
You can also disable the MIME type check completely by setting $wgVerifyMimeType = false; — note however that this is very insecure: arbitrary
files can then be uploaded with a "harmless" file extension, but may possibly still executed/interpreted in a harmful way on the client computer, or the web server.
Pending: how does this relate to
$wgCheckFileExtensions?
