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;
    }
}
