.Net使用RabbitMQ即时发消息Demo

RabbitMQ是一个在AMQP基础上完整的,可复用的企业消息系统,下面这篇文章主要给大家介绍了关于.Net使用RabbitMQ即时发消息的相关资料,文中通过示例代码介绍的非常详细,需要的朋友可以参考下

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));
   }
  }
  }
 }
 }
}

4.程序结果:

注:在第一步之前,你需要安装RabbitMQ客户端,可从http://www.rabbitmq.com/download.html下载,

        但是RabbitMQ又是依赖于Erlang OTP平台,所以,安装RabbitMQ之前,需要先从http://www.erlang.org/download.html下载安装erlang
