TYPO3 ExtBase - 通过 UID 获取调度程序任务并执行它

Question

我的调度程序中有一个 ID 为 5 的任务：

现在我尝试获取任务然后执行它。

...

/**
 * @var \TYPO3\CMS\Scheduler\Scheduler
 * @inject
 */
protected $scheduler;

...

public function createAction($filepath, Strategy $strategy)
{
    ...
    $taskObject = $this->scheduler->fetchTaskRecord(5)["serialized_task_object"];

    $task = unserialize($taskObject);

    if ($this->scheduler->isValidTaskObject($task)) {

        // The task is valid, return it
        $this->scheduler->executeTask($task);
    }

    ...
}

但是我收到以下错误： Fatal error: Call to a member function saveTask() on null in /var/www/typo3/typo3_src-6.2.25/typo3/sysext/scheduler/Classes/Task/AbstractTask.php on line 469

这就是我执行var_dump($taskObject);

得到的结果

string(588) "O:32:"TYPO3\CMS\Extbase\Scheduler\Task":9:{s:20:"*commandIdentifier";s:39:"importr:import:initializeservicemanager";s:12:"*arguments";a:1:{s:12:"extensionKey";s:0:"";}s:11:"*defaults";a:2:{s:12:"extensionKey";N;s:4:"mail";N;}s:10:"*taskUid";i:5;s:11:"*disabled";b:1;s:12:"*execution";O:29:"TYPO3\CMS\Scheduler\Execution":6:{s:8:"*start";i:1475152860;s:6:"*end";i:1475152860;s:11:"*interval";i:0;s:11:"*multiple";i:0;s:10:"*cronCmd";s:0:"";s:23:"*isNewSingleExecution";b:0;}s:16:"*executionTime";i:1475152860;s:14:"*description";s:0:"";s:12:"*taskGroup";i:0;}"

如果我在 isValidTaskObject 检查后立即输出 $task 和 var_dump，那么我只会得到一个空页面。

更准确地说，我在文件 Importr/Classes/Controller/ImportrController.php 的 createAction 函数内部工作，它是扩展 Importr

的一部分

我猜你应该只使用 fetchTask() 而不是 fetchTaskRecord() 来获取任务对象而不是数组。我刚刚试过了，没有出错。

$scheduler = $this->objectManager->get(\TYPO3\CMS\Scheduler\Scheduler::class);
$schedulerTask = $scheduler->fetchTask(1);
$schedulerTask->execute();

不多但至少有一点信息/文档： https://docs.typo3.org/typo3cms/extensions/scheduler/latest/DevelopersGuide/SchedulerApi/Index.html
