怎么在.Net中使用RabbitMQ發(fā)送即時消息?相信很多沒有經(jīng)驗的人對此束手無策,為此本文總結(jié)了問題出現(xiàn)的原因和解決方法,通過這篇文章希望你能解決這個問題。
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(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(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:
