.Net使用RabbitMQ即时发消息Demo_ASP.NET教程

前言

最近项目要使用RabbitMQ，网上已经有很多优秀的文章了，百度百科对RabbitMQ阐述也非常明确，建议去看下，还有amqp协议。必须一提的是rabbitmq是由LShift提供的一个消息队列协议（AMQP)的开源实现，由以高性能、健壮以及可伸缩性出名的Erlang写成（因此也是继承了这些优点）。

最近参考大神们的博客，自己做了一个RabbitMQ即时发消息的Demo。下面话不多说了，来一起看看详细的介绍吧。

步骤如下：

1.使用VS的NuGet安装包管理工具安装RabbitMQ.Client:

2.生产者端代码：

				?

									using System;

									using System.Collections.Generic;

									using System.Linq;

									using System.Text;

									using System.Threading.Tasks;

									using RabbitMQ.Client;

									namespace RabbitMQ.Producter

									{

									 class Program

									 {

									 /// <summary>

									 /// 连接配置

									 /// </summary>

									 private static readonly ConnectionFactory rabbitMqFactory = new ConnectionFactory()

									 {

									  HostName="localhost",

									  UserName = "guest",

									  Password = "guest",

									  Port = 5672,

									  //VirtualHost = "JentVirtualHost"

									 };

									 /// <summary>

									 /// 路由名称

									 /// </summary>

									 const string ExchangeName = "Jent.Exchange";

									 /// <summary>

									 /// 队列名称

									 /// </summary>

									 const string QueueName = "Jent.Queue";

									 static void Main(string[] args)

									 {

									  DirectExchangeSendMsg();

									  Console.WriteLine("按任意键退出程序！");

									  Console.ReadKey();

									 }

									 /// <summary>

									 /// 单点精确路由模式

									 /// </summary>

									 private static void DirectExchangeSendMsg()

									 {

									  using (IConnection conn = rabbitMqFactory.CreateConnection())

									  {

									  using (IModel channel = conn.CreateModel())

									  {

									   channel.ExchangeDeclare(ExchangeName, "direct", durable: true, autoDelete: false, arguments: null);

									   channel.QueueDeclare(QueueName, durable: true, exclusive: false, autoDelete: false, arguments: null);

									   channel.QueueBind(QueueName, ExchangeName, routingKey: QueueName);

									   var props = channel.CreateBasicProperties();

									   props.Persistent = true;

									   Console.WriteLine("请输入需要发送的消息:");

									   string vadata = Console.ReadLine();

									   while (vadata != "exit")

									   {

									   var msgBody = Encoding.UTF8.GetBytes(vadata);

									   channel.BasicPublish(exchange: ExchangeName, routingKey: QueueName, basicProperties: props, body: msgBody);

									   Console.WriteLine(string.Format("发送时间：{0}，发送完毕，输入exit退出消息发送", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")));

									   vadata = Console.ReadLine();

									   }

									  }

									  }

									 }

									 }

									}

3.消费者端代码：

				?

									using System;

									using System.Collections.Generic;

									using System.Linq;

									using System.Text;

									using System.Threading.Tasks;

									using RabbitMQ.Client;

									namespace RabbitMQ.Consumer

									{

									 class Program

									 {

									 /// <summary>

									 /// 连接配置

									 /// </summary>

									 private static readonly ConnectionFactory rabbitMqFactory = new ConnectionFactory()

									 {

									  HostName = "127.0.0.1",

									  UserName = "guest",

									  Password = "guest",

									  Port = 5672,

									  //VirtualHost = "JentVirtualHost"

									 };

									 /// <summary>

									 /// 路由名称

									 /// </summary>

									 const string ExchangeName = "Jent.Exchange";

									 /// <summary>

									 /// 队列名称

									 /// </summary>

									 const string QueueName = "Jent.Queue";

									 static void Main(string[] args)

									 {

									  DirectAcceptExchange();

									  Console.WriteLine("输入任意值退出程序！");

									  Console.ReadKey();

									 }

									 private static void DirectAcceptExchange()

									 {

									  using (IConnection conn = rabbitMqFactory.CreateConnection())

									  {

									  using (IModel channel = conn.CreateModel())

									  {

									   channel.ExchangeDeclare(ExchangeName, "direct", durable: true, autoDelete: false, arguments: null);

									   channel.QueueDeclare(QueueName, durable: true, exclusive: false, autoDelete: false, arguments: null);

									   channel.QueueBind(QueueName, ExchangeName, routingKey: QueueName);

									   while (true)

									   {

									   BasicGetResult msgResponse = channel.BasicGet(QueueName, autoAck: false);

									   if (msgResponse != null)

									   {

									    var msgBody = Encoding.UTF8.GetString(msgResponse.Body);

									    Console.WriteLine(string.Format("接收时间：{0}，消息内容：{1}", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"), msgBody));

									   }

									   //System.Threading.Thread.Sleep(TimeSpan.FromSeconds(1));

									   }

									  }

									  }

									 }

									 }

									}
