使用：
PublishInfo("test", "222222222222");
点击test进入队列内部：
消费消息：
方法一：旧版可用
private static void ConsumeInfo(string queue)
{
try
{
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())
{
//bool durable = true;//将消息标记为持久性
//channel.QueueDeclare("sljcgx:finish-queue", durable, false, false, null);//声明队列，队列不存在则创建该队列
//设置prefetchCount : 1来告知RabbitMQ，在未收到消费端的消息确认时，不再分发消息，也就确保了当消费端处于忙碌状态时，不再分配任务。
channel.BasicQos(prefetchSize: 0, prefetchCount: 1, global: false);
var consumer = new QueueingBasicConsumer(channel);
//false为手动确认，获取消息后需要添加 channel.BasicAck(ea.DeliveryTag, false)确认
//true则为自动确认，不需要这行代码
channel.BasicConsume(queue, false, consumer);
while (true)
{
try
{
var ea = (BasicDeliverEventArgs)consumer.Queue.Dequeue();//阻塞函数，获取队列中的消息
var bodyReceive = ea.Body;
string message = Encoding.UTF8.GetString(bodyReceive);
Console.WriteLine(message);
channel.BasicAck(ea.DeliveryTag, false);// 消息确认信号，确认后该消息将从队列里移除
}
catch (System.Exception ex)
{
Console.WriteLine(ex.Message);
}
}
}
}
}
catch (System.Exception ex)
{
Console.WriteLine(ex.ToString());
}
Console.ReadLine();
}
方法二：（通用）
private static void ConsumeInfo2(string queue)
{
try
{
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
var connection = factory.CreateConnection();
var channel = connection.CreateModel();
channel.QueueDeclare(queue, true, false, false, null);//声明队列，队列不存在则创建该队列
channel.BasicQos(0, 1, false);//公平分发、同一时间只处理一个消息。
var consumer = new EventingBasicConsumer(channel); //消费者（指定消息通道）该事件在接收到消息时触发
consumer.Received += (sender, e) =>
{
byte[] body = e.Body.ToArray(); //消息字节数组
string message = Encoding.UTF8.GetString(body); //消息内容
Console.WriteLine(message);
channel.BasicAck(e.DeliveryTag, false); //手工确认
};
channel.BasicConsume(queue, false, consumer); //消费消息（在当前通道中监听 queue 队列，并进行消费）
Console.ReadLine();
connection.Close();
channel.Close();
}
catch (System.Exception ex)
{
Console.WriteLine(ex.ToString());
}
}
