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：

＃＃＃＃＃＃＃
server.h
＃＃＃＃＃＃＃
#ifndef SERVER_H_
#define SERVER_H_

#include
#include
#include


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){};
};

#endif

＃＃＃＃＃＃＃

＃＃＃＃＃＃＃

}

int XmlrpcServer::setupServer()
{
AbyssServer = new xmlrpc_c::serverAbyss(xmlrpc_c::serverAbyss::constrOpt()
.registryP(&addIntRegistry).socketFd(socket_fd));
cout<< "Xmlrpc server is running......"<< endl;
AbyssServer->run();
cout<< "Xmlrpc server stopped"<< endl;
return 0;
}

int XmlrpcServer::setupSocket()
{
int rc;
int yes = 1;
struct sockaddr_in rm_addr;

socket_fd = socket(AF_INET, SOCK_STREAM, 0);

if (-1 == socket_fd)
{
cout<< "Can not open server socket: " << endl;
return -1;
}

rc = setsockopt(socket_fd, SOL_SOCKET, SO_REUSEADDR, &yes, sizeof(int));

if (-1 == rc)
{

return -1;
}

if (-1 == rc)
{
cout << "Can not bind to port " << port < close(socket_fd);
return -1;
}
return 0;
}

＃＃＃＃＃＃＃＃＃＃
serverMain.cpp
＃＃＃＃＃＃＃＃＃＃
#include "server.h"
#include

using namespace std;

int main(void)
{
XmlrpcServer myServer(2655);
if(myServer.setupSocket() != 0)
return -1;
myServer.regester_xml_method();
if(myServer.setupServer() != 0)
{
cout<< "cannot setup RPC Server"<< endl;
return -1;
}
return 0;
}


＃＃＃＃＃＃＃＃

#include

using namespace std;

int main(int argc,char **argv)
{
int a,b,int_result;
xmlrpc_c::value result;
if(argc != 3)
{
cout<< "please input Two interger numbers: "<< endl;
cin >>a >>b;
}
else
{
a = atoi((argv[1]));
b = atoi((argv[2]));
}

xmlrpc_c::clientSimple myClient;
myClient.call("http://localhost:2655/RPC2","add.int","ii",&result,a,b);
int_result = (xmlrpc_c::value_int)(result);
cout<< "sum of " < return 0;
}

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！
