zeroMq路由模式

项目中遇到对接外部产品，之前用的通讯占用端口较多，并且每次对接都要新建一个通讯，维护麻烦，后面就做了个路由模式，一个端口，一套代码就能对接所有外部产品

直接上代码：

        public static readonly RouterDealerMq Instance = new RouterDealerMq();

        public event Action<string, string> RouterEvent;

        public List<string> IdList { get; private set; } = new List<string>();

        private RouterDealerMq() { }

        private Dictionary<string, Action<string, string>> _actionDic = new Dictionary<string, Action<string, string>>();
        public void InitCon()
        {
            Task.Run(() =>

                    _routerSocket = new RouterSocket();
                    _routerSocket.Bind("tcp://*:5879"); // 绑定端口 
                    _routerSocket.Options.RouterHandover = true;

注意：需要别人传过来的消息是有三帧的，第一帧是id，第二帧是空帧，第三帧是内容
