        const string logOthersQueueName = "log-queue-others";

​
​
var connection = connectionFactory.CreateConnection();
var channel = connection.CreateModel();
​
//设置服务质量
channel.BasicQos(0, 1, false);
​
//定义一个类型为Direct的交换机
channel.ExchangeDeclare(exchangeName, ExchangeType.Direct, true, false, null);
​
​
//定义一个队列,将用于存放日志级别为 Warn,Info,Debug的日志
channel.QueueDeclare(queue: logOthersQueueName, durable: true, exclusive: false, autoDelete: false, arguments: null);
​
​
​
//将debug，info，warn 都绑定到log-queue-others"队列中
var routingKeys = new[] { "info", "warn", "debug" };
foreach (var routingKey in routingKeys)
{
channel.QueueBind(logOthersQueueName, exchangeName, routingKey, null);
}
​
//定义消费者
var consumer = new EventingBasicConsumer(channel);
consumer.Received += (model, ea) =>
{
var body = ea.Body;
var message = Encoding.UTF8.GetString(body);
Console.WriteLine(" [x] Received {0} " + DateTime.Now, message);
channel.BasicAck(ea.DeliveryTag, false);
};
channel.BasicConsume(queue: logOthersQueueName, false, consumer: consumer);
​
​
Console.WriteLine(" Press [enter] to exit.");
Console.ReadLine();
}
}
}
​

- 这里我们把log-queue-others队列绑定到了交换机上,并指定了routingKey为info,warn和debug.这样会产生三组路由.info,warn,debug三种级别的日志均被路由到log-queue-others队列上
- 按照预期设计,将消费发送序号!=10的倍数的日志.
