极光推送 代理服务器

使用HttpProxy做代理 , 出现这个错误.

Caused by: java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 400 Bad Request"

备注 : 创建JPushClient客户端的方式这样子吗 ?

HttpProxy httpProxyUrl = new HttpProxy("代理服务器", 端口号);
jPushClient = new JPushClient(masterSecret, appKey, 3, httpProxyUrl);
