200
Response content length: 3509
content-type:text/html
----------------------------------------
用网面打开www.baidu.com 编码会自动设置成GB312
为什么httpClient里没取得编码看下了其源代码头 ,httpClient 没用java 里URLconnection 去实现，而是用最底层的socket 去实现的要怎么要才取得content-type里的charset ???

这个就是本网页的头文件，你代码解析其中的红色部分不就行了么。
然后自己找
“charset=”后面的字符串就是编码/
