定义与描述

Web Service也称为web服务，它是一种跨编程语言和操作系统平台的远程调用技术。Web Service采用标准的SOAP协议传输（SOAP：Simple Object Access Protocol简单对象访问协议，soap属于w3c标准。并且soap协议是基于http的应用层协议传输xml数据）。Web Service采用WSDL作为描述语言，也就是Web Service 的使用说明书。并且W3C为Web Service制定了一套传输数据类型，使用xml进行描述，即XSD（XML Schema Datatypes），任何语言写的web Service 接口在发送数据的时候都要转换成WebService标准的XSD发送。
