序言
emmmmmmm~~~，通过前六章相信你对php操作RabbitMQ有了一定的掌握，在这一章将使用ThinkPHP6实战。
操作环境
- php7.3与apache
- 框架为tp6
tp6设置
开启多应用（按需开启）
composer require topthink/think-multi-app
完善多应用（按需添加文件夹）
自定义命令
- 使用命令生成自定义命令文件
命令文件代码
<?php
declare (strict_types = 1);
namespace app\command;
use think\console\Command;
use think\console\Input;
use think\console\input\Argument;
use think\console\input\Option;
use think\console\Output;
use app\common\controller\MqConsumer;
class Order extends Command
{
protected function configure()
{
// 指令配置
$this->setName('order')
->setDescription('the order command');
}
protected function execute(Input $input, Output $output)
{
// 指令输出
$consumer = new MqConsumer();
$consumer->consumer('order');
}
}
<?php
declare (strict_types = 1);
namespace app\command;
use think\console\Command;
use think\console\Input;
use think\console\input\Argument;
use think\console\input\Option;
use think\console\Output;
use app\common\controller\MqConsumer;
class Goods extends Command
{
protected function configure()
{
// 指令配置
$this->setName('goods')
->setDescription('the goods command');
}
protected function execute(Input $input, Output $output)
{
$consumer = new MqConsumer();
$consumer->consumer('goods');
}
}
- 在根目录config文件夹下的console.php文件中注册命令。
<?php
// +----------------------------------------------------------------------
// | 控制台配置
// +----------------------------------------------------------------------
return [
// 指令定义
'commands' => [
'order' => 'app\command\order',
'goods' => 'app\command\goods'
],
];
rabbitMQ配置
在根目录config文件夹下新建rabbitmq.php文件。
<?php
// +----------------------------------------------------------------------
// | rabbitMQ 示例配置
// +----------------------------------------------------------------------
return [
// 连接信息
'AMQP' => [
'host' => '127.0.0.1',
'port' => '5672',
'username' => 'guest',
'password' => 'guest',
'vhost' => '/'
],
//topic队列
'topic_queue' => [
'exchange_name' => 'topic_exchange',
'exchange_type' => 'topic',
'queue_name' => 'topic_queue',
'route_key' => '',
'consumer_tag' => 'topic'
],
//商品队列
'goods_queue' => [
'exchange_name' => 'topic_exchange',
'exchange_type' => 'topic',
'queue_name' => 'goods_queue',
'route_key' => '*.goods',
'consumer_tag' => 'goods'
],
//订单队列
'order_queue' => [
'exchange_name' => 'topic_exchange',
'exchange_type' => 'topic',
'queue_name' => 'order_queue',
'route_key' => '*.order',
'consumer_tag' => 'order'
],
//...等等队列
];
最终目录结构
生产者代码
<?php
namespace app\common\controller;
use think\facade\Config;
use think\facade\Log;
use PhpAmqpLib\Connection\AMQPStreamConnection;
use PhpAmqpLib\Message\AMQPMessage;
class MqProducer
{
public function publish($data, $key)
{
//获取配置
$amqp = Config::get('rabbitmq.AMQP');
$amqpDefail = Config::get('rabbitmq.topic_queue');
//连接
$connection = new AMQPStreamConnection(
$amqp['host'],
$amqp['port'],
$amqp['username'],
$amqp['password']
);
//建立通道
$channel = $connection->channel();
//初始化交换机
$channel->exchange_declare($amqpDefail['exchange_name'], $amqpDefail['exchange_type'], false, true, false);
//生成消息
$msg = new AMQPMessage(json_encode($data), [
'content-type' => 'application/json',
'delivery_mode' => AMQPMessage::DELIVERY_MODE_PERSISTENT
]);
//推送消息到某个交换机
$channel->basic_publish($msg, $amqpDefail['exchange_name'], $key);
$channel->close();
$connection->close();
echo 'send';
}
}
消费者代码
<?php
namespace app\common\controller;
use think\facade\Config;
use think\facade\Log;
use PhpAmqpLib\Connection\AMQPStreamConnection;
use PhpAmqpLib\Exchange\AMQPExchangeType;
class MqConsumer
{
/**
* 消费者
*/
public function consumer($name)
{
//获取配置
$amqp = Config::get('rabbitmq.AMQP');
$amqpDefail = Config::get('rabbitmq.'.$name.'_queue');
//连接
$connection = new AMQPStreamConnection(
$amqp['host'],
$amqp['port'],
$amqp['username'],
$amqp['password']
);
//建立通道
$channel = $connection->channel();
//流量控制
$channel->basic_qos(null, 1, null);
//初始化交换机
$channel->exchange_declare($amqpDefail['exchange_name'], $amqpDefail['exchange_type'], false, true, false);
//初始化队列
$channel->queue_declare($amqpDefail['queue_name'], false, true, false, false);
//绑定队列与交换机
$channel->queue_bind($amqpDefail['queue_name'], $amqpDefail['exchange_name'], $amqpDefail['route_key']);
//消费消息
$channel->basic_consume($amqpDefail['queue_name'], $amqpDefail['consumer_tag'], false, false, false, false, [$this, 'msgProc']);
//退出
register_shutdown_function([$this, 'shutdown'], $channel, $connection);
//监听
while(count($channel->callbacks)) {
$channel->wait();
}
}
/**
* 消息处理
* @param $msg
*/
public function msgProc($msg)
{
echo $msg->body."\n";
$msg->ack();
}
/**
* 退出
* @param $channel [信道]
* @param $connection [连接]
*/
public function shutdown($channel, $connection)
{
$channel->close();
$connection->close();
}
}
调用者代码
<?php
namespace app\index\controller;
use app\BaseController;
use app\common\controller\MqProducer;
class Index extends BaseController
{
public function index()
{
$data = ['id'=>rand(1,100), 'msg'=>'lalala'];
$producer = new MqProducer();
$producer->publish($data, 'all.order');
}
public function index2()
{
$data = ['id'=>rand(1,100), 'msg'=>'lalala'];
$producer = new MqProducer();
$producer->publish($data, 'all.goods');
}
}
