Laravel 7.2.2
我正在现有工作中使用 Laravel 创建工作。触发第一个作业可以正常工作，一旦触发第二个作业，它就会崩溃并出现以下错误：
Too few arguments to function App\Jobs\CreateAlarm::__construct(), 0 passed in C:\xxx\Dispatchable.php on line 17 and exactly 3 expected in C:\xx\Jobs\CreateAlarm.php:29
意思是我没有通过任何参数，而预期有 3 个参数。我正在使用以下代码来解雇这项工作：
class ProcessMeasurement implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
protected $sid;
protected $val1;
protected $val2;
/**
* Create a new job instance.
*
* @return void
*/
public function __construct($sid, $val1, $val2)
{
$this->sid = $sid;
$this->val1 = $val1;
$this->val2 = $val2;
}
/**
* Execute the job.
*
* @return void
*/
public function handle()
{
$measurement = new Measurement;
$measurement->sensor_id = $this->sid;
$measurement->value_1 = $this->val1;
$measurement->value_2 = $this->val2;
$measurement->save();
// Check for triggers
$triggers = SensorTrigger::where('sensor_id', $this->sid)->get();
foreach ($triggers as $trigger) {
// check if alarm must be triggered
if ($trigger->operator == '>') {
// use > operator
if ($trigger->affected_value == 1) {
// check value 1
if ($measurement->value_1 > $trigger->operand) {
// trigger alarm
$job = (new CreateAlarm($this->sid, $trigger->id, Measurement::max('id')));
$job->dispatch();
}
}
if ($trigger->affected_value == 2) {
// check value 2
if ($measurement->value_2 > $trigger->operand) {
// trigger alarm
$job = (new CreateAlarm($this->sid, $trigger->id, Measurement::max('id')));
$job->dispatch();
}
}
}
...
}
}
}
}
我在作业 CreateAlarm: 中传递了 3 个变量$this->sid，$trigger->id并且Measuerment::max('id')
这是 CreateAlarm 的样子：
class CreateAlarm implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
protected $sid;
protected $trigger_id;
protected $measurement_id;
/**
* Create a new job instance.
*
* @return void
*/
public function __construct($sid, $trigger_id, $measurement_id)
{
$this->sid = $sid;
$this->trigger_id = $trigger_id;
$this->measurement_id = $measurement_id;
}
/**
* Execute the job.
*
* @return void
*/
public function handle()
{
// Store alarm in database
$alarm = new Alarm;
$alarm->trigger_id = $this->trigger_id;
$alarm->trigger_type = 'automatic';
$alarm->measurement_id = $this->measurement_id;
$alarm->organisation_id = Sensor::where('id', $this->sid)->organisation_id;
$alarm->sensor_id = $this->sid;
// check who to call
$sensorContacts = SensorContact::where('sensor_id', $this->sid)->where('phone_priority', 0)->get();
$alarm_id = Alarm::max('id');
foreach ($sensorContacts as $sensorContact) {
if ($sensorContact->phone_active == 1) {
// Create call job
$callJob = (new ProcessAlarmCall($sensorContact->contact_id, $alarm_id));
$callJob->dispatch();
}
if ($sensorContact->email_active == 1) {
// Create mail job
$mailJob = (new ProcessAlarMEmail($sensorContact->contact_id, $alarm_id));
$mailJob->dispatch();
}
if ($sensorContact->whatsapp_active == 1) {
// Create whatsapp job
$whatsappJob = (new ProcessAlarmWhatsapp($sensorContact->contact_id, $alarm_id));
$whatsappJob->dispatch();
}
}
}
}
我添加了每个变量protected $var，然后在 __construct 中构造它。
我找不到我做错了什么以及为什么工作失败
