Linux下 XmlRpc C++服务端客户端实现(cc)

下面是转载的一篇文章，在ubuntu下试验成功。转自：http://bbs.php100.com/apps.php?q=diary&uid=56398&a=detail&did=1265

服务端实现步骤：
    1. 创建socket套接字，并在某个端口打开；
    2. 定义并注册服务端方法；
    3. 运行服务端。
客户端实现步骤：
    1. 调用服务端注册的方法；
    2. 处理返回信息。
如下为一个XmlRpc的代码实现：

#define SERVER_H_

#include <xmlrpc-c/base.hpp>
#include <xmlrpc-c/registry.hpp>

class XmlrpcServer
{
private:
        class MyTestMethod: public xmlrpc_c::method
        {
        public:
                MyTestMethod()
                {
                  this->_signature = "A:ii";
                      this->_help = "This method adds two integers together";
                       }
  
                void execute(xmlrpc_c::paramList const& paramList,xmlrpc_c::value * const retval)
                {
                      const int addend(paramList.getInt(0));
                      const int adder(paramList.getInt(1));
  
                   *retval = (xmlrpc_c::value_int)(addend+adder);
                      }
        };
private:      
        xmlrpc_c::registry             addIntRegistry;
        xmlrpc_c::serverAbyss*      AbyssServer;
        int                                 port;
        int                                 socket_fd;
      
public:
        void    regester_xml_method();
        int    setupServer();
        int    setupSocket();
public:
        XmlrpcServer(int _port):port(_port),socket_fd(-1){};
};

用gcc编译器编译，编译命令为：
服务端：
gcc -Wall -g server.cpp serverMain.cpp -o server.deamon -lstdc++ -lxmlrpc++ -lxmlrpc_server_abyss++ -lxmlrpc_server

客户端：
gcc -g -Wall -o add_int clientMain.cpp -lstdc++ -lxmlrpc_client++

测试：
可执行文件生成成功后，运行 " ./server.deamon "
然后执行 " ./add_int 1 2 " 得输出结果：sum of 1 and 2 is 3
执行 ./add_int 1456 456465 3
please input Two interger numbers:
4 9
sum of 4 and 9 is 13
运行成功！
