假设这个服务提供了一个名称为sayHello
的公共可用函数。 此函数需要单个字符串参数并返回单个字符串问候语。 例如,如果传递参数值为:world
,那么服务函数sayHello
将返回问候语:Hello,world!
。

示例分析说明
- 定义 -
HelloService
- 类型 - 使用内置数据类型,它们在XMLSchema中定义。
- 消息 -
sayHelloRequest
-firstName
参数sayHelloresponse
- 问候的返回值
- 端口类型 - 由请求和响应服务组成的
sayHello
操作。 - 绑定 - 使用SOAP HTTP传输协议的方向。
- 服务 - 可从 http://www.examples.com/SayHello/ 获取服务
- 端口 - 将绑定与URI => http://www.examples.com/SayHello/ 相关联,可以访问正在运行的服务。
