解决mediawiki 文件扩展名 与检测到的文件MIME类型(application/zip)不匹配

在mediawiki中，如果上传doc或者docx文件时，经常会出现：文件扩展名".***" 与检测到的文件MIME类型(application/zip)不匹配   的警告。要想去掉这个警告，需要更改includes目录下的DefaultSettings.php文件，其中的 $wgVerifyMimeType = false，  即可。

本内容取自mediawiki官方文档。原文内容如下：

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?
