.Net使用RabbitMQ即时发消息Demo

时间:2021-05-28

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:///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
