laravel failed_job 还原

laravel will execute the failed job into failed_job table, payload stores information of job, job in the objects we need to restore analyze the cause of failure.

---

1. Tracking the source code found on the job objects are serialized, and then add other parameters json transformation, then we will be doing exactly the opposite

vendor/illuminate/queue/Queue.php:85

json_encode([
                'job' => 'Illuminate\Queue\CallQueuedHandler@call',
                'data' => ['command' => serialize(clone $job)],
            ]);

---

2. Failed_job directly to the exterior of the payload assigned to a variable, and then parse the line. It should be noted that the problem escapes the string, which is the reason I use nowdoc way. nowdoc way does not resolve any of the escape character, protects the integrity of json string.

$jobStr = <<<'EOF'
{"job":"Illuminate\\Queue\\CallQueuedHandler@call","data":{"command":"O:19:\"App\\Jobs\\CaseReport\":6:{s:5:\"queue\";s:12:\"cases-report\";s:7:\"\u0000*\u0000case\";i:6369701;s:7:\"\u0000*\u0000pool\";i:20;s:9:\"\u0000*\u0000record\";N;s:6:\"\u0000*\u0000job\";N;s:5:\"delay\";N;}"},"id":"c43gA7efKgVl9TavrqloRBiRY9sD0KeD","attempts":2}
EOF;

$job = json_decode($jobStr,true);
$command = $job['data']['command'];
$obj = unserialize($command);
dd($obj);

Output:

App\Jobs\CaseReport {#116
  +queue: "cases-report"
  #case: 6369701
  #pool: 20
  #record: null
  #job: null
  +delay: null
}
