IIS启用JSON压缩

文件地址：Windows\System32\inetsrv\config\applicationHost.config

在其中的<dynamicTypes>（即动态压缩类型）节中增加以下两个配置即可：

<add mimeType="application/json" enabled="true" />

<add mimeType="application/json; charset=utf-8" enabled="true" />

配置完毕后

<system.webServer>
    <urlCompression doDynamicCompression="true" />
    <httpCompression>
      <dynamicTypes>
        <add mimeType="application/json" enabled="true" />
        <add mimeType="application/json; charset=utf-8" enabled="true" />       
      </dynamicTypes>
    </httpCompression>
</system.webServer>
