WSDL简介@H_404_7@
WSDL，Web Services Description Language，Web Service的描述语言，是一种接口定义语言，用于描述Web Service的接口信息等。（描述Web服务和说明如何与Web服务通信的XML语言。为用户提供详细的接口说明书。）@H_404_7@
WSDL元素@H_404_7@
WSDL有五大元素，分别是types，message，portType，binding和service。@H_404_7@
types:用来定义访问的类型
message:SOAP Message
portType:指明服务器的接口，并且通过operation绑定相应的in和out消息(in:参数,out:返回值)
binding:指定传递消息所使用的格式
service:指定服务所发布的名称@H_404_7@
