关于 Laravel Redis 多个进程同时取队列问题详解

public function pushRaw($payload, $queue = null, array $options = [])
{
 $this->getConnection()->rpush($this->getQueue($queue), $payload);
 
 return Arr::get(json_decode($payload, true), 'id');
}

public function pop($queue = null)
{
 $original = $queue ?: $this->default; 
 $queue = $this->getQueue($queue); 
 $this->migrateExpiredJobs($queue.':delayed', $queue); 
 if (! is_null($this->expire)) {
  $this->migrateExpiredJobs($queue.':reserved', $queue);
 } 
 list($job, $reserved) = $this->getConnection()->eval(
  LuaScripts::pop(), 2, $queue, $queue.':reserved', $this->getTime() + $this->expire
 ); 
 if ($reserved) {
  return new RedisJob($this->container, $this, $job, $reserved, $original);
 }
}
