ROUTINGKEY绑定各自的QUEUE实例

1、简单设置场景

需要一个日志系统，使用RabbitMQ推送

日志等级要求如下：

Log levels
debug、info、warning、error、none

2、代码实现

1）生产者

//基础配置
            ConnectionFactory factory = new ConnectionFactory()
            {
                HostName = "10.123.44.12",
                UserName = "datamip",
                Password = "datamip"
            };

            //第一步：创建connection
            using (var connection = factory.CreateConnection())
            {
                //第二步：创建channel
                using (var channel = connection.CreateModel())
                {
                    //第三步：创建exchange
                    channel.ExchangeDeclare("myexchange", ExchangeType.Direct, true, false, null);

                    //第四步：发布消息，直接绑定对应的routingkey
                    for (int i = 0; i < 100; i++)
                    {

                        var msg = Encoding.UTF8.GetBytes(string.Format("{0}:{1}", i, "你好"));
                        var level = i % 13 == 0 ? "info" : "error";//方便演示
                        channel.BasicPublish("myexchange", level, basicProperties: null, body: msg);
                    }

                }
            }
            Console.WriteLine("生产成功!");
            Console.ReadKey();

　　

2）消费者

i:info消费者

            //创建连接工厂
            ConnectionFactory factory = new ConnectionFactory
			{
				UserName = "datamip",//用户名
				Password = "datamip",//密码
				HostName = "10.123.44.12"//rabbitmq ip
			};           
            //第一步：创建connection
            using (var connection = factory.CreateConnection())
            {
                //第二步：创建channel
                using (var channel = connection.CreateModel())
                {
                    //第三步：生明交换机
                    channel.ExchangeDeclare("myexchange", ExchangeType.Direct, true, false, null);

                    //第四步：声明队列,绑定交换机
                    channel.QueueDeclare("log_else",true,false,false,null);
                    //绑定当前需要消费的routingkey
                    channel.QueueBind("log_else", "myexchange", "info", null);

                    //处理消息
                    EventingBasicConsumer consumer = new EventingBasicConsumer(channel);
                    consumer.Received += (sender,e)=> {
                        var msg = Encoding.UTF8.GetString(e.Body.ToArray());
                        Console.WriteLine(msg);
                    };
                    //消费
                    channel.BasicConsume("log_else", true, consumer);
                    Console.ReadKey();
                }
            }   

ii:error消费者

            //创建连接工厂
            ConnectionFactory factory = new ConnectionFactory
            {
                UserName = "datamip",//用户名
                Password = "datamip",//密码
                HostName = "10.123.44.12"//rabbitmq ip
            };
            //第一步：创建connection
            using (var connection = factory.CreateConnection())
            {
                //第二步：创建channel
                using (var channel = connection.CreateModel())
                {
                    //第三步：生明交换机
                    channel.ExchangeDeclare("myexchange", ExchangeType.Direct, true, false, null);

                    //第四步：声明队列,绑定交换机
                    channel.QueueDeclare("log_error", true, false, false, null);
                    //绑定当前需要消费的routingkey
                    channel.QueueBind("log_error", "myexchange", "error", null);

                    //处理消息
                    EventingBasicConsumer consumer = new EventingBasicConsumer(channel);
                    consumer.Received += (sender, e) => {
                        var msg = Encoding.UTF8.GetString(e.Body.ToArray());
                        Console.WriteLine(msg);
                    };
                    //消费
                    channel.BasicConsume("log_error", true, consumer);
                    Console.ReadKey();
                }
            }
