android----AsyncHttpClient的get,post和图片上传

async-http-client库是一个基于回调函数的Http异步通信客户端Android组件，是在Apache的HttpClient库的基础上开发构建而成的。

Eclipse使用：导入android-async-http-1.4.4.jar 包, 点击下载

AndroidStudio: gradle中引入 compile 'com.loopj.android:android-async-http:1.4.8'

功能特色

  • 利用版4.3.6上游HttpClient代替Android提供defaulthttpclient
  • 兼容AndroidAPI 23高
  • 做异步HTTP请求处理的响应匿名回调
  • HTTP请求发生UI线程之外
  • 请求使用线程池限制并发资源使用情况
  • get /后参数生成器（ RequestParams ）
  • 多文件上传没有额外的第三方库
  • JSON上传流没有额外的图书馆
  • 处理循环和相对重定向
  • 小的开销给你的应用程序只90kb一切
  • 自动智能请求重试次数质量不一的移动连接优化
  • 自动gzip响应解码速度超快的请求支持
  • 二进制协议通信binaryhttpresponsehandler
  • 内置的响应分析JSON与jsonhttpresponsehandler
  • 节能反应直接进入文件fileasynchttpresponsehandler
  • 大的持久性Cookie，保存cookie到你的应用程序的SharedPreferences
  • 杰克逊JSON集成，gson或其他JSON序列化库（德）basejsonhttpresponsehandler
  • 与SAX解析器支持saxasynchttpresponsehandler
  • 语言和内容编码的支持，不仅仅是UTF-8
