开启IIS的动态gzip功能

首先安装IIS的动态压缩模块

然后打开system32/intesrv下的applicationhost文件，找到其中的webServer节点，将其中的压缩配置部分替换如下：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
    
    <httpCompression directory="%SystemDrive%inetpub	empIIS Temporary Compressed Files">
      <scheme name="gzip" dll="%Windir%system32inetsrvgzip.dll" staticCompressionLevel="9" />
      <dynamicTypes>
        <add mimeType="text/*" enabled="true" />
        <add mimeType="message/*" enabled="true" />
        <add mimeType="application/x-javascript" enabled="true" />
        <add mimeType="application/json" enabled="true" />
        <add mimeType="*/*" enabled="false" />
      </dynamicTypes>
      <staticTypes>
        <add mimeType="text/*" enabled="true" />
        <add mimeType="message/*" enabled="true" />
        <add mimeType="application/x-javascript" enabled="true" />
        <add mimeType="application/atom+xml" enabled="true" />
        <add mimeType="application/xaml+xml" enabled="true" />
        <add mimeType="*/*" enabled="false" />
      </staticTypes>
    </httpCompression>
    
    <urlCompression doStaticCompression="true" doDynamicCompression="true" />
    
  </system.webServer>
</configuration>

最后重启IIS即可。
