C++如何动态调用Web Services

tomorrowzls 2014-01-22 03:50:47
求问C++如何动态调用Web Services? gSoap应该不行，因为它要根据wsdl手动生成头文件。现在的需求是可以支持扩展，对于之前没有的服务，知道其uri就可访问它的服务

ps：提供服务的接口名称已知
刚刚接触web services，可能描述不准确。

更改 EndPointURL 属性的值. 在URL里指定你的服务器名. OK 总结一下必要的关键步骤 1.导入类型库 2.需要创建一个SoapConnector 3.下一步创建SoapSerializer 4.下一步把消息附加到SoapConnector的输入流 5.下一步读取结果.要读取服务器的回复,客户端应用需要使用SoapReader, 6.SoapReader被连接到SoapConnector输出流 7.用IXMLDOMElement对象可以从SoapReader里读到服务器的回复
我用你这种方法，为什么用C#写的web service那边收到的参数都是null呢

gsoap也可以吧？你写好gsoap头文件，用soapcpp2.exe生成客户端代码，也不用实现服务器方法
