1.先部署好RabbitMQ
2.进入登录页面
3.创建虚拟机
4.添加新用户
5.新用户绑定虚拟机
6.代码创建与rabbitmq链接
需下载引用包
public class RabbitMQHelper
{
///
/// 获取RabbitMQ连接对象方法(创建与RabbitMQ的连接)
///
///
public static IConnection GetConnection() {
//创建连接工厂【设置相关属性】
var connectionFactory = new ConnectionFactory()
{
//设置IP
HostName = "127.0.0.1",//RabbitMQ地址
Port = 5672,//端口
VirtualHost = "/test",//RabbitMQ中要请求的VirtualHost名称
UserName ="test",//RabbitMQ用户
Password= "test"//RabbitMQ用户密码
};
//通过工厂创建连接对象
return connectionFactory.CreateConnection();
}
}
7.简单模式
生产者
///
/// 简单队列模式-生产者
///
public class SampleProducer
{
///
/// 简单队列模式
/// 生产者
/// 通过管道向RabbitMQ发送消息
///
public void SendMessage() {
//获取连接对象
using var connection=RabbitMQHelper.GetConnection();
//创建管道
using var channel= connection.CreateModel();
//创建队列
channel.QueueDeclare("sample_queue",false,false,false,null);
for (int i = 0; i < 5; i++)
{
string msg = $"Hello Word Message{i + 1}";
var body = Encoding.UTF8.GetBytes(msg);
//向RabbitMQ发送消息
//routingKey指定发往哪个队列(如routingkey和队列名相同则为默认队列)
//exchange为空则默认链接的交换机, false,null, body为消息主体
channel.BasicPublish("", "sample_queue", false, null, body);
//输出发送的消息
Console.WriteLine(msg);
}
}
}
消费者
///
/// 简单队列模式-消费者
///
public class SampleConsumer
{
///
/// 简单队列模式
/// 消费者
/// 通过管道向RabbitMQ获取消息且消费消息
///
public static void ConsumerMessage() {
//获取连接对象
var connection=RabbitMQHelper.GetConnection();
//创建管道
var chennel=connection.CreateModel();
//创建队列(如队列已存在的情况可不用再次创建/此创建为:确保先开启消费者,生产者未创建队列而引发报错)
chennel.QueueDeclare("sample_queue", false, false, false, null);
//事件对象
var consumer= new EventingBasicConsumer(chennel);
consumer.Received += (model, ea) => {
//获取消息
var body=ea.Body;//获取队列中消息主体
var msg=Encoding.UTF8.GetString(body.ToArray());//转为string
var routingkey=ea.RoutingKey;//队列名
Console.WriteLine($"message is:{msg} ,routingkey => {routingkey}");
};
//消费消息
chennel.BasicConsume("sample_queue", true, consumer);
}
}
8.发布订阅模式

///
public void SendMessage() {
//获取连接对象
using var connection = RabbitMQHelper.GetConnection();
//创建管道
using var channel = connection.CreateModel();
//创建交换机
channel.ExchangeDeclare("fanout_Exchange","fanout",false,false,null);
//创建队列
channel.QueueDeclare("fanout_queue1",false,false,false,null);
channel.QueueDeclare("fanout_queue2", false, false, false, null);
channel.QueueDeclare("fanout_queue3", false, false, false, null);
//把队列绑定到交换机(就是队列订阅交换机)
channel.QueueBind("fanout_queue1", "fanout_Exchange", "",null);
channel.QueueBind("fanout_queue2", "fanout_Exchange", "", null);
channel.QueueBind("fanout_queue3", "fanout_Exchange", "", null);
for (int i = 0; i < 10; i++)
{
string msg = $"RabbiteMQ fanout Message{i+1}";
var body=Encoding.UTF8.GetBytes(msg);
//发送消息
//创建了交换机则不需要routingkey了,因为只需要队列订阅交换机即可
//消息发送到交换机,创建了的队列订阅了交换机则会自动去交换机拿值
channel.BasicPublish("fanout_Exchange","",false,null,body);
Console.WriteLine(msg);
}
}
