我正在处理一个队列作业，该作业从其他API导入一些数据并存储它们。
从我的控制器中，当我说$this->dispatchNow(new ImportPatentsJob($numbers, $count, $invention_id, $redisId));时，它一切正常，过程一定会顺利进行。
但是当我将其更改为dispatch并将作业排队，然后通过队列工作程序运行它时，它会失败。我的工作看起来像：
protected $numbers;
protected $count;
protected $invention_id;
protected $redisId;
/**
* Create a new job instance.
*
* @return void
*/
public function __construct($numbers, $count, $invention_id, $redisId)
{
$this->numbers = $numbers;
$this->count = $count;
$this->invention_id = $invention_id;
$this->redisId = $redisId;
$this->onQueue('import');
$this->setUpClients();
}
protected function setUpClients()
{
$this->imageClient = new Client([
'base_uri' => 'some-uri',
'headers' => ['API-TOKEN' => env('API_TOKEN')],
]);
$this->dataClient = new Client([
'base_uri' => 'some-uri',
'headers' => ['API-TOKEN' => env('API_TOKEN')],
]);
$this->familyClient = new Client([
'base_uri' => 'some-uri',
'headers' => ['API-TOKEN' => env('API_TOKEN')],
]);
}
/**
* Execute the job.
*
* @return void
*/
public function handle()
{
$folder_id = $this->createFolder();
$currentCount = 0;
foreach ($this->numbers as $number) {
$currentCount++;
Redis::executeRaw(['SET', 'importlog:' . $this->redisId, 'Import ' . $number['number']]);
try {
$response = $this->dataClient->get($number['number']); // this is line 85 where the exception occurs
} catch (\Exception $e) {
Redis::executeRaw(['SET', 'importlog:' . $this->redisId . ':fail:' . $number['number'], 'Could not import']);
Log::info($e);
continue;
}
$data = $this->decodeData($response);
$patent_id = $this->createPatentDocument($data, $folder_id);
$this->createPatentAddresses($data, $patent_id);
$this->createPatentApplications($data, $patent_id);
$this->createPatentPriorities($data, $patent_id);
$this->createPatentCitations($data, $patent_id);
$this->createPatentTaxonomies($data, $patent_id);
$this->createPatentTitles($data, $patent_id);
$this->createPatentAbstracts($data, $patent_id);
$this->createPatentClaims($data, $patent_id);
$this->createPatentDescriptions($data, $patent_id);
$this->createInventionResults($this->invention_id, $patent_id, $number['position']);
try {
$response = $this->imageClient->get($data['bibliographic']['root']['family']);
$blob = $this->fetchImageBlob($response, $number['number']);
if ($blob) {
$this->createFile($blob, $patent_id);
}
} catch (\Exception $e) {
Redis::executeRaw([
'SET',
'importlog:' . $this->redisId . ':fail:image:' . $number['number'],
'Patent number: ' . $number['number'] . '; Family number: ' . $data['bibliographic']['root']['family'],
]);
}
Redis::executeRaw([
'SET',
'importlog:' . $this->redisId . ':progress',
"Import progress: " . $currentCount . '/' . $this->count . '(' . ($currentCount / $this->count * 100) . '%)'
]);
}
}
我在try catch语句中说Log::info($e)时失败了。例外情况如下：

它说dataClient属性未定义但我无法弄清楚原因。它几乎已定义，并且在作业未排队时效果很好。我做错了什么？
更新
所以我意识到我忘了为客户声明受保护的属性。但是一旦我这样做，我就遇到了这个错误。作业不再排队，但Exception说：Serialization of 'Closure' is not allowed
我假设我无法以序列化和存储Guzzle客户端
答案 0 :(得分：3)
所以Guzzle闭包没有被序列化，因为它无法序列化闭包。是什么让我失望。
Exception: Serialization of 'Closure' is not allowed
如果遇到同样的问题，这可以是一个很好的起点。
我以更简单的方式解决了这个问题。我刚刚在句柄方法中移动了客户端的声明，并使它们成为局部变量，在这种情况下，它们不必被序列化，只需坐在那里直到某些工作使用它们。
