求个玩过这个的大佬。现在遇到一些问题，有偿求助一下
Selenium, Browsermob-Proxy获取network的har时候，默认返回是br数据(默认的accept-encoding有br，就算一开始默认的不写br数据，但是在后续的页面接口里面还是会用上)，这个browsermob-proxy好像无法解析br数据。导致我无法获取xhr content的text值，拿不到自己想要的数据
browsermob-proxy的报错日志：
[WARN 2020-10-08T10:38:58,704 net.lightbody.bmp.filters.ServerResponseCaptureFilter] (LittleProxy-3-ProxyToServerWorker-1) Cannot decode unsupported content encoding type br
[WARN 2020-10-08T10:38:58,704 net.lightbody.bmp.filters.HarCaptureFilter] (LittleProxy-3-ProxyToServerWorker-1) Unable to decompress content with encoding: br. Contents will be encoded as base64 binary data.
