.Net Core中使用RabbitMQ
（1）、引入依赖
RabbitMQ.Client
（2）、编写发布者代码
1 var connectionFactory = new ConnectionFactory() { HostName="192.168.205.128",UserName="guest",Password="guest"}; //创建连接工厂 2 var connection = connectionFactory.CreateConnection(); //创建connection 3 var channel = connection.CreateModel(); //创建channel 4 //声明交换机 5 //String exchange, 交换机名称 6 //String type, 交换机类型 7 //Boolean durable, 是否持久化 8 //Boolean autoDelete, 是否自动删除 9 //IDictionary< String, Object > arguments 交换机参数 10 channel.ExchangeDeclare("netExchange", ExchangeType.Direct, true, false, null); 11 //声明队列 12 //String queue, 队列名称 13 //Boolean durable, 是否持久化 14 //Boolean exclusive, 是否专有的（排外） 15 //Boolean autoDelete, 是否自动删除 16 //IDictionary<String, Object> arguments 队列参数 17 channel.QueueDeclare("netQueue", true, false, false, null); 18 //将队列绑定到交换机上 19 //String queue, 队列名称 20 //String exchange, 交换机名称 21 //String routingKey, routingKey 22 //IDictionary< String, Object > arguments 绑定参数 23 channel.QueueBind("netQueue", "netExchange", "netMessage", null); 24 //发布消息 25 //String exchange, 交换机名称 26 //String routingKey, routingKey 27 //IBasicProperties basicProperties, 发布属性 28 //Byte[] body 消息内容 29 channel.BasicPublish("netExchange", "netMessage", null, Encoding.UTF8.GetBytes("来自.net的问候")); 30 Console.ReadKey();
（3）、编写消费者代码
1 var connectionFactory = new ConnectionFactory() { HostName = "192.168.205.128", UserName = "guest", Password = "guest" }; //创建连接工厂 2 var connection = connectionFactory.CreateConnection(); //创建connection 3 var channel = connection.CreateModel(); //创建channel 4 //声明交换机 5 //String exchange, 交换机名称 6 //String type, 交换机类型 7 //Boolean durable, 是否持久化 8 //Boolean autoDelete, 是否自动删除 9 //IDictionary< String, Object > arguments 交换机参数 10 channel.ExchangeDeclare("netExchange", ExchangeType.Direct, true, false, null); 11 //声明队列 12 //String queue, 队列名称 13 //Boolean durable, 是否持久化 14 //Boolean exclusive, 是否专有的（排外） 15 //Boolean autoDelete, 是否自动删除 16 //IDictionary<String, Object> arguments 队列参数 17 channel.QueueDeclare("netQueue", true, false, false, null); 18 //将队列绑定到交换机上 19 //String queue, 队列名称 20 //String exchange, 交换机名称 21 //String routingKey, routingKey 22 //IDictionary< String, Object > arguments 绑定参数 23 channel.QueueBind("netQueue", "netExchange", "netMessage", null); 24 //1.直接获取消息 25 //var result = channel.BasicGet("netQueue", true); 26 //Console.WriteLine(Encoding.UTF8.GetString(result.Body)); 27 //2.使用事件机制获取消息 28 EventingBasicConsumer consumer = new EventingBasicConsumer(channel); 29 consumer.Received += (sender, e) => 30 { 31 Console.WriteLine(Encoding.UTF8.GetString(e.Body)); 32 }; 33 channel.BasicConsume("netQueue", true, consumer); 34 Console.ReadKey();
