php 使用rabbitmq 踩坑记录

环境

1.安装rabbit

php使用

安装包，直接安装composer 安装php-amqplib/php-amqplib 这个包

生产着

1. 连接mq server

require_once __DIR__.'/vendor/autoload.php';
use PhpAmqpLib\Connection\AMQPStreamConnection;
use PhpAmqpLib\Exchange\AMQPExchangeType;
use PhpAmqpLib\Message\AMQPMessage;

$connection = new AMQPStreamConnection("127.0.0.1", 5672, "guest", "guest", "yedong_test");  //连接server
$channel = $connection->channel(); //创建通道

1. 创建交换机

$exchange="example_direct_exchange";
/*
name: $exchange
type: fanout  交换机类型
passive: false // don't check if an exchange with the same name exists 
durable: false // the exchange won't survive server restarts  //是否是持久化
auto_delete: true //the exchange will be deleted once the channel is closed. 
*/
$channel->exchange_declare($exchange, AMQPExchangeType::DIRECT, false, true, true);

3.创建队列

//参数
        $queue = '',   //队列名称
        $passive = false, //检查是否村子啊
        $durable = false, //是否持久化
        $exclusive = false, //排外，①当前定义的队列是connection的channel是共享的，其他的connection是访问不到的。②当connection关闭的时候，队列将被删除。
        $auto_delete = true, //空是自动删除
        $nowait = false,     //
        $arguments = array(),
        $ticket = null

$channel->queue_declare("test_queue_3",true,true,false,false,false,[],null);

4.绑定队列和交换机，生成routing_key

$channel->queue_bind("example_direct_queue_2",$exchange,"routeTest1");

5.发送消息到队列

![clipboard.png](/img/bVbrPRr)

$msg = new AMQPMessage($i, ['content_type' => 'text/plain','delivery_mode'=>2]); //2:持久化，重启不会丢失，默认为1，重启会丢失
$channel->basic_publish($msg, $exchange,"routeTest1");
