WSDL
WSDL（网络服务描述语言，Web Services Description Language）是一门基于 XML 的语言，用于描述 Web Services 以及如何对它们进行访问。
WSDL 文档结构
基本格式：
<definitions><types> definition of types........</types><message> definition of a message....</message><portType> definition of a port.......</portType><binding> definition of a binding....</binding></definitions>
示例：
WSDL 端口
<portType> 元素是最重要的 WSDL 元素。它可描述一个 web service、可被执行的操作，以及相关的消息。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）。
操作类型
WSDL 消息
<message> 元素定义一个操作的数据元素。每个消息均由一个或多个部件组成。可以把这些部件比作传统编程语言中一个函数调用的参数。
WSDL types
<types> 元素定义 web service 使用的数据类型。为了最大程度的平台中立性，WSDL 使用 XML Schema 语法来定义数据类型。
WSDL Bindings
<binding> 元素为每个端口定义消息格式和协议细节。
