前言

最近項目要使用RabbitMQ，網上已經有很多優秀的文章了，百度百科對RabbitMQ闡述也非常明確，建議去看下，還有amqp協議。必須一提的是rabbitmq是由LShift提供的一個消息隊列協議（AMQP)的開源實現，由以高性能、健壯以及可伸縮性出名的Erlang寫成（因此也是繼承了這些優點）。

最近參考大神們的博客，自己做了一個RabbitMQ即時發消息的Demo。下面話不多說了，來一起看看詳細的介紹吧。

步驟如下：

1.使用VS的NuGet安裝包管理工具安裝RabbitMQ.Client:

2.生產者端代碼：

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>
 /// 連接配置
 /// </summary>
 private static readonly ConnectionFactory rabbitMqFactory = new ConnectionFactory()
 {
 HostName="localhost",
 UserName = "guest",
 Password = "guest",
 Port = 5672,
 //VirtualHost = "JentVirtualHost"
 };
 /// <summary>
 /// 路由名稱
 /// </summary>
 const string ExchangeName = "Jent.Exchange";
 /// <summary>
 /// 隊列名稱
 /// </summary>
 const string QueueName = "Jent.Queue";
 static void Main(string[] args)
 {
 DirectExchangeSendMsg();
 Console.WriteLine("按任意鍵退出程序！");
 Console.ReadKey();
 }
 /// <summary>
 /// 單點精確路由模式
 /// </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("請輸入需要發送的消息:");
 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("發送時間：{0}，發送完畢，輸入exit退出消息發送", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")));
 vadata = Console.ReadLine();
 }
 }
 }
 }
 }
}

3.消費者端代碼：

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>
 /// 連接配置
 /// </summary>
 private static readonly ConnectionFactory rabbitMqFactory = new ConnectionFactory()
 {
 HostName = "127.0.0.1",
 UserName = "guest",
 Password = "guest",
 Port = 5672,
 //VirtualHost = "JentVirtualHost"
 };
 /// <summary>
 /// 路由名稱
 /// </summary>
 const string ExchangeName = "Jent.Exchange";
 /// <summary>
 /// 隊列名稱
 /// </summary>
 const string QueueName = "Jent.Queue";

 static void Main(string[] args)
 {
 DirectAcceptExchange();

 Console.WriteLine("輸入任意值退出程序！");
 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("接收時間：{0}，消息內容：{1}", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"), msgBody));
 }
 //System.Threading.Thread.Sleep(TimeSpan.FromSeconds(1));
 }
 }
 }
 }
 }
}
