XUtils开源项目---HttpUtils网络处理

最近搜了XUtils进行学习，该开源库是目前git上比较活跃 功能比较完善的一个框架，是基于afinal开发的，比afinal稳定性提高了不少.

这篇博客记录的是网络请求操作，源码下载地址   XUtils开源项目---HttpUtils网络处理

• HttpUtils模块：

  • 支持同步，异步方式的请求；
  • 支持大文件上传，上传大文件不会oom；
  • 支持GET，POST，PUT，MOVE，COPY，DELETE，HEAD，OPTIONS，TRACE，CONNECT请求；
  • 下载支持301/302重定向，支持设置是否根据Content-Disposition重命名下载的文件；
  • 返回文本内容的请求(默认只启用了GET请求)支持缓存，可设置默认过期时间和针对当前请求的过期时间。

主页面布局--布局有3个按钮，分别是get请求，post请求，下载操作
