HttpURLConnection 发送Soap get/post请求

Soap： Simple Object Access Protocol ——简单对象访问协议
   1.soap作为一个基于xml语言的协议用于网上传输数据
       2.SOAP = HTTP + XML
       3.SOAP是基于HTTP的（这里顺便补充一下，Http是基于Socket的）
       4.SOAP的组成如下
       1.Envelope: 必须的，以XML根元素出现
           2.Header：可选的
           3.Body：必须的，在body部分包含一些，执行服务器的方法，和发送到服务器的数据
