前言:最近因为工作忙，没抽出时间来继续文章的下半部分，现在手头忙的差不多，便抽时间写了这篇文章！
- 上篇文章只是简单的介绍了，rabbitmp的搭建和基础发送队列，封装了一个公用类。
connection = new AMQPStreamConnection($config['host'], $config['port'], $config['user'], $config['pass']);
$this->queue_key = $queue_name;
$this->exchange_suffix = $config['exchange'];
$this->priority=$priority;
$this->channel = $this->connection->channel();
$this->bind_exchange();
return $this->connection;
}
/**
* 绑定交换机
* @return mixed|null
*/
protected function bind_exchange() {
$queue_key=$this->queue_key;
$exchange_key = $this->exchange_suffix;
$this->exchange_key = $exchange_key;
$channel = $this->channel;
if(!empty($this->priority)){
$priorityArr = array('x-max-priority' => array('I', $this->priority));
$size = $channel->queue_declare($queue_key, false, true, false, false,false,$priorityArr);
}else{
$size = $channel->queue_declare($queue_key, false, true, false, false);
}
$channel->exchange_declare($exchange_key, 'topic', false, true, false);
$channel->queue_bind($queue_key, $exchange_key,$queue_key);
$this->channel=$channel;
return $size ;
}
/**
* 发送数据到队列
* @param $data = array('key'=>'val')
*/
public function put($data)
{
$channel = $this->channel;
$value = json_encode($data);
$toSend = new AMQPMessage($value, array('content_type' => 'application/json', 'delivery_mode' => 2));
$channel->basic_publish($toSend, $this->exchange_key,$this->queue_key);
}
/**
* 获取数据
* @return mixed
*/
public function get()
{
$channel = $this->channel;
$message = $channel->basic_get($this->queue_key);
if (!$message) {
return array(null,null);
}
$ack = function() use ($channel,$message) {
$channel->basic_ack($message->delivery_info['delivery_tag']);
};
$result = json_decode($message->body,true);
return array($ack,$result);
}
/**
* 关闭链接
*/
public function close() {
$this->channel->close();
$this->connection->close();
}
/**
* 获得队列长度
* @return int
*/
public function length(){
$info = $this->bind_exchange();
return $info[1];
}
}
- 发送队列简单demo
'web',//自己手动添加交换机,这里就不做描述
'host' => '172.17.0.6',//填写自己的容器ip
'port' => '5672',
'user' => 'guest',
'pass' => 'guest',
];
$queue = new RabbitMq($rabbitMqConfig, $queueName);
$data = ['uuid' => rand(100,99999999)];
$queue->put($data);
echo '发送完成,发送的内容:'.print_r($data,1);
exit();
}
}

'web',//自己手动添加交换机,这里就不做描述
'host' => '172.17.0.6',//填写自己的容器ip
'port' => '5672',
'user' => 'guest',
'pass' => 'guest',
];
$queue = new RabbitMq($rabbitMqConfig, $queueName);
$cnt = 0;
while (1) {
list($ack,$data) = $queue->get();
if(!$data){
$cnt++;
if($cnt > 20){
$queue->close();
exit();
}
echo "no data:$cnt \n";
sleep(1);
continue;
}
//逻辑处理
echo "start work \n";
print_r($data);
echo "end work \n";
//确认消耗
$ack();
}
}
}
- 配置supervisor的消耗队列进程(PS:我的demo.ini是放在我创建的docker项目容器里的,不熟悉的小伙伴可以看看我的关于创建容器的文章)
a. 创建文件
vim demo.ini
b. 编写配置(PS:注意这里用的是yii的console,请根据你们的使用来进行更改)
;测试demo
[program:demo]
command= /usr/share/nginx/html/advanced/yii test/test
directory=/usr/share/nginx/html/advanced/
stdout_logfile=/tmp/demo.log
redirect_stderr=true
autostart=false
autorestart=false
c. 增加进程
supervisorctl update
d. 成功添加,demo进程已启动,通过supervisorctl tail -f demo 看进程消耗
image.png
e. 再查看队列状态,显示队列已被消耗

结尾
好了,到此为止,简单的队列消耗已经完成,可能有些地方不是说的太清楚,毕竟自己也在摸索中,文章中的如果有不对的地方欢迎指正,共同学习~
