节点关闭api

ros::shutdown()

 修改之前的pub.cpp

    ros::Publisher pub = n.advertise<std_msgs::String>("chongfu",1000,true);
    std_msgs::String msg;
    ros::Rate rate(1);
    int count = 0;
    while (ros::ok())
    {
        count++;
        std::stringstream ss;
        ss << "hello -->" << count;
        msg.data = ss.str();
        if(count <= 10)
        {
            pub.publish(msg);
            ROS_INFO("发布数据：%s", msg.data.c_str());
            rate.sleep(); 
        }
        else
        {
            ros::shutdown();
        }
        // pub.publish(msg);
        // ROS_INFO("发布数据：%s", msg.data.c_str());
        // rate.sleep();
        ros::spinOnce();
