gSOAP calc服务端与客户端示例

1. Web服务定义描述头文件

typedef double xsd__double;
int ns__add(xsd__double a, xsd__double b, xsd__double &result);
int ns__sub(xsd__double a, xsd__double b, xsd__double &result);
int ns__sqrt(xsd__double a, xsd__double &result);

 

2. 生成服务端与客户端代码

soapcpp2 calc.h

 

3. 服务端工程 / 客户端工程对比

 

4. 服务端main.cpp
