消費者：web

 static void Main(string[] args)
        {
            ConnectionFactory factory = new ConnectionFactory()
            {
                HostName = "192.168.254.40",
                UserName = "admin",
                Password = "admin",
            };

            //第一步：建立connection
            var connection = factory.CreateConnection();

            //第二步：建立一個channel
            var channel = connection.CreateModel();

            //第三步：申明交換機【由於rabbitmq已經有了自定義的ampq default exchange】
            channel.ExchangeDeclare("myheadersexchange", ExchangeType.Headers, true, false, null);

            //第四步：建立一個隊列(queue)
            channel.QueueDeclare("myheadersqueue", true, false, false, null);

            //將queue綁定到exchange之上。。。。
            channel.QueueBind("myheadersqueue", "myheadersexchange", string.Empty, new Dictionary<string, object>()
            {
                {"x-match", "all"},
                {"username", "jack"},
                {"password", "12345" }
            });

            EventingBasicConsumer consumer = new EventingBasicConsumer(channel);

            consumer.Received += (sender, e) =>
            {
                var msg = Encoding.UTF8.GetString(e.Body);

                Console.WriteLine(msg);
            };

            channel.BasicConsume("myheadersqueue", true, consumer);

            Console.WriteLine("consumer1 端啓動完畢！！！");

            Console.Read();
        }

static void Main(string[] args)
        {
            ConnectionFactory factory = new ConnectionFactory()
            {
                HostName = "192.168.254.40",
                UserName = "admin",
                Password = "admin",
            };

            //第一步：建立connection
            var connection = factory.CreateConnection();

            //第二步：建立一個channel
            var channel = connection.CreateModel();

            var properties = channel.CreateBasicProperties();

            properties.Headers = new Dictionary<string, object>();

            properties.Headers.Add("password", "12345");
            properties.Headers.Add("username", "jack");

            for (int i = 0; i < 100; i++)
            {
                var msg = Encoding.UTF8.GetBytes(string.Format("{0} :{1}", i, "你好"));

                //第五步：發佈消息
                channel.BasicPublish("myheadersexchange", routingKey: string.Empty, basicProperties: properties, body: msg);

                Console.WriteLine(i);
            }
        }
