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
