使用polipo解决webrtc gclient sync失败的问题

问题

在同步webrtc代码，使用gclient sync，如下只给git配置socks5代理总会失败。 [http] proxy = socks5://127.0.0.1:22222 [https] proxy = socks5://127.0.0.1:22222 会报如下错误 ____ running 'cipd ensure -log-level error -root /home/xxx/webrtc/webrtc-checkout -ensure-file /tmp/tmpSfax2e.ensure' in '.'

分析

发现是gclient会访问一些被墙掉的网址，需要配置http的全局代理。

解决

使用polipo，将socks5代理转换成全局的http代理。 1.安装polipo sudo apt-get install polipo 2.配置polipo， vi /etc/polipo/config 添加 socksParentProxy=127.0.0.1:22223 3.重启服务 sudo service polipo restart 4.配置全局http代理 export http_proxy=127.0.0.1:8123 export https_proxy=127.0.0.1:8123 5.这时gclient sync就能成功了
