| ##立即执行
push($job, $data, $queue)
Queue::push(Test::class, ['id' => 1], 'test');
一顿骚操作后返回一个数组 并且序列化后 rPush到redis中 key为 queue:queueName
数组结构:
[
'job' => $job, // 要执行任务的类
'data' => $data, // 任务数据
'id'=>'xxxxx' //任务id
]
写入 redis并且返回队列id
至于中间的那顿骚操作太长了就没写
延迟发布
later($delay, $job, $data, $queue)
Queue::later(100, Test::class, ['id' => 1], 'test');
跟上面的差不多
一顿骚操作后返回一个数组 并且序列化后 zAdd 到redis中 key为 queue:queueName:delayed score为当前的时间戳+$delay
执行过程
执行过程有work模式和listen模式 两种 区别上面已经说了 代码逻辑由于太多等下回分解;
最后讲一下标签的使用
//守护进程开启
'worker_daemon_start' => [
\app\index\behavior\WorkerDaemonStart::class
],
//内存超出
'worker_memory_exceeded' => [
\app\index\behavior\WorkerMemoryExceeded::class
],
//重启守护进程
'worker_queue_restart' => [
\app\index\behavior\WorkerQueueRestart::class
],
//任务开始执行之前
'worker_before_process' => [
\app\index\behavior\WorkerBeforeProcess::class
],
//任务延迟执行
'worker_before_sleep' => [
\app\index\behavior\WorkerBeforeSleep::class
],
//任务执行失败
'queue_failed' => [
\app\index\behavior\QueueFailed::class
]
public function run(Output $output)
{
$output->write('<info>任务执行失败</info>', true);
}
控制台执行 php think queue:work --queue test --daemon
会在控制台一次输出
守护进程开启
任务延迟执行
失败的处理 如果有任务执行失败或者执行次数达到最大值
会触发 queue_failed
在app\index\behavior@run方法里面写失败的逻辑 比如邮件通知 写入日志等
最后我们来说一下如何在其他框架或者项目中给tp的项目推送消息队列,例如两个项目是分开的 另一个使用的却不是tp5的框架
在其他项目中推任务
