WSDL文档结构

a. portType : 
i. 它可描述一个 web service、可被执行的操作，以及相关的消息。
ii. 可以把 <portType> 元素比作传统编程语言中的一个函数库（或一个模块、或一个类）。
iii. 实际就是 WebService 服务端(Server) 的接口.(当然了,WSDL端口似乎更高大上一点..)
 
b. message : 这里我的理解是 , message 是 对外开放的方法.(那个..Response 我还不知道是干嘛用的..)

c. type : 定义了一些 Server 端发布接口的数据类型

d. 在上面的例子中,仔细看,可以发现,在<wsdl:type>中,有两组<xs:complexType>节点,他们之间就定义了,对外开放接口的入参类型.

e. binding : 定义了通信协议.
