.Net使用RabbitMQ即时发消息Demo

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
