Raiitmq分布式消息队列分发机制(c#)

切身体会到消息队列的好用，rabiitmq采用排队消费，数据会及时传到rabiitmq server上

下面我们来定义生产者一号

public static void Main(string[] args)
{
var factory = new ConnectionFactory();
factory.HostName = "localhost";//RabbitMQ服务在本地运行
factory.UserName = "guest";//用户名
factory.Password = "guest";//密码
using (var connection = factory.CreateConnection())
{
using (var channel = connection.CreateModel())
{
channel.QueueDeclare("hello rabiitmq", true, false, false, null);//创建一个名称为hello的消息队列
//int prefetchCount = 1;

//每个消费者发送确认信号之前，消息队列不发送下一个消息过来，一次只处理一个消息 
//限制发给同一个消费者不得超过1条消息 
channel.BasicQos(0, 1, false);

// 发送的消息 
for (int i = 0; i < 50; i++)
{
String message = "生产者一号生产消息" + i;
// 往队列中发出一条消息 
channel.BasicPublish("", "hello rabiitmq", null, Encoding.UTF8.GetBytes(message));
Console.WriteLine("队列生产 '" + message + "次'");
Thread.Sleep(i * 10);
}
// 关闭频道和连接 
channel.Close();
connection.Close();


}
}
Console.ReadKey();

下面我们来定义生产者二号

public static void Main(string[] args)
{
var factory = new ConnectionFactory();
factory.HostName = "localhost";//RabbitMQ服务在本地运行
factory.UserName = "guest";//用户名
factory.Password = "guest";//密码
using (var connection = factory.CreateConnection())
{
using (var channel = connection.CreateModel())
{
channel.QueueDeclare("hello rabiitmq", true, false, false, null);//创建一个名称为hello的消息队列
//int prefetchCount = 1;

//每个消费者发送确认信号之前，消息队列不发送下一个消息过来，一次只处理一个消息 
//限制发给同一个消费者不得超过1条消息 
channel.BasicQos(0, 1, false);

// 发送的消息 
for (int i = 0; i < 50; i++)
{
String message = "生产者二号生产消息" + i;
// 往队列中发出一条消息 
channel.BasicPublish("", "hello rabiitmq", null, Encoding.UTF8.GetBytes(message));
Console.WriteLine("队列生产 '" + message + "次'");
Thread.Sleep(i * 20);
}
// 关闭频道和连接 
channel.Close();
connection.Close();


}
}
Console.ReadKey();

下面我们来定义消费者

public static void Main(string[] args)
{
var factory = new ConnectionFactory();
factory.HostName = "localhost";
factory.UserName = "guest";
factory.Password = "guest";
using (var connection = factory.CreateConnection())
{
using (var channel = connection.CreateModel())
{
channel.QueueDeclare("hello rabiitmq", true, false, false, null);
channel.BasicQos(0, 1, false);

var consumer = new QueueingBasicConsumer(channel);
channel.BasicConsume("hello rabiitmq", false, consumer);

while (true)
{
var ea = (BasicDeliverEventArgs)consumer.Queue.Dequeue();

var body = ea.Body;
var message = Encoding.UTF8.GetString(body);

int dots = message.Split('.').Length - 1;
Thread.Sleep(dots * 1000);

Console.WriteLine("消费者成功接收消息 {0}", message);
Console.WriteLine("End");

channel.BasicAck(ea.DeliveryTag, false);
}

Boolean autoAck = false; //手动确认消息
channel.BasicConsume("hello rabiitmq", autoAck, consumer);


}
}
}

分别执行后

自己记录一下，慢慢发现编程乐趣。
