RabbitMQ 笔记

1：发送

Uri uri = new Uri("amqp://10.0.4.85:5672/");

ConnectionFactory factory = new ConnectionFactory();
factory.UserName = "abc";
factory.Password = "abcdef";
factory.VirtualHost = "dnt_mq";
factory.RequestedHeartbeat = 0;
factory.Endpoint = new AmqpTcpEndpoint(uri);

string exchange = "ex1";
string exchangeType = "direct";
string routingKey = "Q1";

using (IConnection conn = factory.CreateConnection())
{
using (IModel ch = conn.CreateModel())
{
if (exchangeType != null)
{
ch.ExchangeDeclare(exchange, exchangeType);//,true,true,false,false, true,null);
ch.QueueDeclare("MyFirstQueue", true, true, true, null);
ch.QueueBind("MyFirstQueue", exchange, routingKey);
}
string jsonStr = "abc";//JsonConvert.SerializeObject(requestMsg);
byte[] bytes = Encoding.UTF8.GetBytes(jsonStr);

IBasicProperties properties = ch.CreateBasicProperties();
properties.DeliveryMode = 2;

ch.BasicPublish(exchange, routingKey, properties, bytes);

/*
* channel.queueBind("queueName", "exchangeName", "routingKey.*");
* channel.basicPublish("exchangeName", "routingKey.one", properties, bytes);
*
* channel.exchangeDeclare("exchangeName", "fanout"); //direct fanout topic
* channel.basicPublish("exchangeName", "", properties, bytes);
* */
}
