Webservice wsdl 结构简介 数据结构WebServiceSOAP编程ASP

WSDL 文档在Web服务的定义中使用下列元素：

    Types - 数据类型定义的容器，它使用某种类型系统(一般地使用XML Schema中的类型系统)。
    Message - 通信消息的数据结构的抽象类型化定义。使用Types所定义的类型来定义整个消息的数据结构。
    Operation - 对服务中所支持的操作的抽象描述，一般单个Operation描述了一个访问入口的请求/响应消息对。
    PortType - 对于某个访问入口点类型所支持的操作的抽象集合，这些操作可以由一个或多个服务访问点来支持。
    Binding - 特定端口类型的具体协议和数据格式规范的绑定。
    Port - 定义为协议/数据格式绑定与具体Web访问地址组合的单个服务访问点。
    Service- 相关服务访问点的集合。
