.apk等常用文件下载出现如果应下载文件，请添加 iis MIME 映射。

在下载.apk文件时出现错误。

HTTP 错误 404.3 - Not Found

由于扩展配置问题而无法提供您请求的页面。如果该页面是脚本，请添加处理程序。如果应下载文件，请添加 MIME 映射。

原因是iis中没有配置特定的文件类型。

1、win+R,inetmgr打开iis

2、选中iis中的服务器名称（即配置整个iis的mime，会对所有网站起作用，而不要选单个网站，否则配置重复时会报mime文件错误，网站中的css,js,img等文件都会加载错误），双击Mime类型，添加，上面输入.apk，下面输入

 application/vnd.android.package-archive 

 

（1）如果对单个网站配置mime,增加了apk文件类型，则会在该网站的config文件中增加一句apk mime相关的代码（具体代码记不清了），以后若iis再整体配置mime apk时，则此网站会报mime重复配置错误，网站中的css,js,img等文件都会加载错误，网站会访问不到静态文件，即使从浏览器地址直接访问文件出来的也是乱码。

常用文件的MIME类型

安卓

.apk  application/vnd.andriod

苹果

.ipa  application/vnd.iphone

----------------------------------------------------------------------------------------------------------------------

MIME类型就是设定某种扩展名的文件用一种应用程序来打开的方式类型，
当该扩展名文件被访问的时候，浏览器会自动使用指定应用程序来打开。
多用于指定一些客户端自定义的文件名，以及一些媒体文件打开方式。

下面列出常用的文件对应的MIME类型：

    其实，这些格式管理员都可以自己添加的，系统会自动生成MIME头，当然可能会有一些稀少的文件格式，还需要检测后才能获得它们的MIME格式，一般通用的系统都可以自动生成。
    支持java下载：在iis中需要添加
