redis发布订阅

• redis订阅发布：轻量级，低延迟，高并发，低可靠性
• 传统MQ，如rabbitmq：重量级，高可靠，异步，不保证实时

C# ServiceStack.Redis实现简单发布订阅
订阅客户端

        static void Main(string[] args)
        {
            using (RedisClient consumer = new RedisClient("118.25.189.165", 6379, "XXXX"))
            {
                //创建订阅
                IRedisSubscription subscription = consumer.CreateSubscription();
                //接受到消息时
                subscription.OnMessage = (channel, msg) =>
                {
                    Console.WriteLine(DateTime.Now.ToString("[yyyy-MM-dd HH:mm:ss]") + " 频道：" + channel + " 消息：" + msg);
                };
                //订阅频道时
                subscription.OnSubscribe = (channel) =>
                {
                    Console.WriteLine("订阅客户端：开始订阅" + channel);
                };
                //取消订阅频道时
                subscription.OnUnSubscribe = (a) => { Console.WriteLine("订阅客户端：取消订阅"); };

                //订阅频道
                subscription.SubscribeToChannels("channel1");
            }
        }

发布客户端

        static void Main(string[] args)
        {
            Console.WriteLine("请输入发布的消息");
            using (RedisClient client = new RedisClient("118.25.189.165", 6379, "XXXX"))
            {
                while (true)
                {
                    string str = Console.ReadLine();

                    client.PublishMessage("channel1", str);
                }
            }
        }
