thinkphp 6 消息队列

 

1.安装think-queue

composer require topthink/think-queue

 

2.配置消息队列,将config/queue.php将’default’ => ‘sync’改为’default’ => ‘redis’,使用Redis驱动

 

如选择database,需创建表

CREATE TABLE `prefix_jobs` ( `id` int(11) NOT NULL AUTO_INCREMENT, `queue` varchar(255) NOT NULL, `payload` longtext NOT NULL, `attempts` tinyint(3) unsigned NOT NULL, `reserve_time` int(10) unsigned DEFAULT NULL, `available_time` int(10) unsigned NOT NULL, `create_time` int(10) unsigned NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

 

3.创建生产者

 

class Index extends BaseController
{
    
    /**
     * 单任务
     */
    public function singleTask()
    {
        //当前任务将由哪个类来负责处理
        $jobHandlerClassName = 'app\job\Job1';
        //业务数据 对象需要手动转序列化
        $jobData = ['ts' => time()];
        //队列名称
        $jobQueueName = "createOrderJob";
        //入队列,later延时发送,单位秒。push立即发送
        $isPushed = Queue::later(2, $jobHandlerClassName, $jobData,$jobQueueName);
        //$isPushed = Queue::push( $jobHandlerClassName , $jobData , $jobQueueName );
        // database 驱动时,返回值为 1|false  ;   redis 驱动时,返回值为 随机字符串|false
        if( $isPushed !== false ){
            echo '执行成功';
        }else{
            echo '执行失败';
        }
        //php think queue:listen --queue createOrderJob  执行队列
        //nohup php think queue:listen --queue createOrderJob &  不以守护进程执行
    }
 
    /**
     * 多任务
     */
    public function multiTask(){
        $taskType = $_GET['taskType'];
        switch ($taskType) {
            case 'taskA':
                $jobHandlerClassName  = 'app\job\MultiTask@taskA';
                $jobDataArr = ['a'   => '1'];
                $jobQueueName = "multiTaskJobQueue";
                break;
            case 'taskB':
                $jobHandlerClassName  = 'app\job\MultiTask@taskB';
                $jobDataArr = ['b'   => '2'];
                $jobQueueName = "multiTaskJobQueue";
                break;
            default:
                break;
        }
 
        $isPushed = Queue::push($jobHandlerClassName, $jobDataArr, $jobQueueName);
        if ($isPushed !== false) {
            echo("the $taskType of MultiTask Job has been Pushed to ".$jobQueueName ."<br>");
        }else{
            echo "push a new $taskType of MultiTask Job Failed!";
        }
    }
 
}

4.创建消费者

单任务

class Job1
{
    public function fire(Job $job, $data)
    {
        //业务处理代码,具体不贴出来了
        $isJobDone = $this->jobDone($data);
        //执行成功删除
        if($isJobDone){
            $job->delete();
            print("任务已经被执行成功并且删除");
        }else{
            $job->release(3); //$delay为延迟时间 表示该任务延迟3秒后再执行
            print("任务3s后再次被执行");
        }
        //通过这个方法可以检查任务重试了几次
        if ($job->attempts() > 3) {
            print("Job has been retried more than 3 times!");
            $job->delete();
        }
    }
 
    public function failed($data)
    {
        // ...任务达到最大重试次数后,失败了
    }
 
    private function jobDone($data){
        Log::write('这是数据 ' . json_encode($data));
        return true;
    }

多任务

class MultiTask{
    public function taskA(Job $job,$data){
 
        $isJobDone = $this->_doTaskA($data);
 
        if ($isJobDone) {
            $job->delete();
            print("Info: TaskA of Job MultiTask has been done and deleted"."\n");
        }else{
            $job->release(3);
            print("任务3s后再次被执行");
        }
        if ($job->attempts() > 3) {
            print("Job has been retried more than 3 times!");
            $job->delete();
        }
    }
 
    public function taskB(Job $job,$data){
 
        $isJobDone = $this->_doTaskB($data);
 
        if ($isJobDone) {
            $job->delete();
            print("Info: TaskB of Job MultiTask has been done and deleted"."\n");
        }else{
            $job->release(3);
            print("任务3s后再次被执行");
        }
        if ($job->attempts() > 3) {
            print("Job has been retried more than 3 times!");
            $job->delete();
        }
    }
 
    private function _doTaskA($data) {
        print("Info: doing TaskA of Job MultiTask "."\n");
        return true;
    }
 
    private function _doTaskB($data) {
        print("Info: doing TaskB of Job MultiTask "."\n");
        return true;
    }
}

5.执行

php think queue:listen --queue createOrderJob   //(队列名)

 --daemon  //可后台运行,具体看手册

 

//$job->delete();   删除任务
//$job->attempts();  查看任务执行次数
// 注意:执行完任务后必须删除任务

 

 

 

 

在database 模式下,2.7.1 和 2.7.2 中的重发逻辑是先删除原来的任务,然后插入一个新的任务。2.7.3 中的重发时机是直接更新原任务。

而在redis 模式下,3种重发都是先删除再插入。

不管是哪种重发方式,重发之后,任务的已尝试次数会在原来的基础上 +1 。

此外,消费者类中需要注意,如果 fire() 方法中可能抛出异常,那么如果不需要自动重发的话, 请在抛出异常之前将任务删除 $job->delete() ,以免产生bug。 如果需要自动重发的话,请直接抛出异常,不要在 fire() 方法中又手动使用 $job->release() , 这样会导致该任务被重发两次,产生两个一样的新任务。

 

 可配合supervisor使用,保证进程常驻
