zero ice 如何获取本地以及对端IP 地址及端口号

 // 在客户端显示端点连接IP及端口号信息
 static void show_endpoint(const Ice::ObjectPrx &proxy)
 {
     Ice::ConnectionPtr conn = proxy->ice_getConnection();
     if(conn)
     {
         cout << conn->type() << endl;
         cout << conn->toString() << endl;
         Ice::ConnectionInfoPtr conn_info = conn->getInfo();
         ::Ice::EndpointPtr ep_ptr = conn->getEndpoint();
         cout << ep_ptr->toString() << endl;

         Ice::IPConnectionInfoPtr ipInfo = Ice::IPConnectionInfoPtr::dynamicCast(conn_info);
         cout << ipInfo->localAddress << ":" << ipInfo->localPort << endl;
         cout << ipInfo->remoteAddress << ":" << ipInfo->remotePort << endl;
     }
     else
     {
         cout << "collocated" << endl;
     }
 }
