对HttpClient的理解

HttpClient 架包下载地址



get post请求 可以看到用httpClient 进行post get 请求是相对代码量少些，但是最新的的android studio不怎么支持它，解决方法可以用



但是这里又会出现一个问题  HttpClients所属的架包没有得到解决，（httpclients应该是最新apache所用的方法，如果用以前的老方法进行get post请求不用httpClients就可以必避免这个问题，把下载的包都放入libs目录中又会报一些错误，总之google对Apache支持不是很好，用android studio工具开发的话慎用apache httpclient，eclipse开发的话就要顺利很多。）
