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
/**
* soap较rest具有比较好的可靠性与安全性
*
* soap是一种固定的规范
*
* 能够满足应用上下文信息与对话状态管理
