RabbitMQ是一個(gè)在AMQP基礎(chǔ)上完整的，可復(fù)用的企業(yè)消息系統(tǒng)，下面這篇文章主要給大家介紹了關(guān)于.Net使用RabbitMQ即時(shí)發(fā)消息的相關(guān)資料，文中通過(guò)示例代碼介紹的非常詳細(xì)，需要的朋友可以參考下

前言

最近項(xiàng)目要使用RabbitMQ，網(wǎng)上已經(jīng)有很多優(yōu)秀的文章了，百度百科對(duì)RabbitMQ闡述也非常明確，建議去看下，還有amqp協(xié)議。必須一提的是rabbitmq是由LShift提供的一個(gè)消息隊(duì)列協(xié)議（AMQP)的開(kāi)源實(shí)現(xiàn)，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(yōu)點(diǎn)）。

最近參考大神們的博客，自己做了一個(gè)RabbitMQ即時(shí)發(fā)消息的Demo。下面話不多說(shuō)了，來(lái)一起看看詳細(xì)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(chǎn)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(duì)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(diǎn)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(qǐng)輸入需要發(fā)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(fā)送時(shí)間：{0}，發(fā)送完畢，輸入exit退出消息發(fā)送", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")));
   vadata = Console.ReadLine();
   }
  }
  }
 }
 }
}

3.消費(fèi)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(duì)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(shí)間：{0}，消息內(nèi)容：{1}", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"), msgBody));
   }
   //System.Threading.Thread.Sleep(TimeSpan.FromSeconds(1));
   }
  }
  }
 }
 }
}

4.程序結(jié)果：
