Laravel Tips: 5 个调度方法
1. skip() & when()
If you want your scheduled task to execute only when some condition is true, use when() to set such conditions inline:
$schedule->command('your:command')->when(function () {
return some_condition();
});skip() is the exact opposite of the when() method. If the skip method returns true, the scheduled task will not be executed:
$schedule->command('emails:send')->daily()->skip(function(){
return Calendar::isHolidauy();
});2. withoutOverlapping()
You may be running a critical job that should only have one instance running at a time. That's where withoutOverlapping() ensures that a scheduled task won't overlap, preventing potential conflicts.
$schedule->command('your:command')->withoutOverlapping();3. thenPing()
After executing a task, you might want to ping a URL to notify another service or trigger another action. thenPing() lets you do just that seamlessly.
$schedule->command('your:command')->thenPing('http://example.com/webhook');4. runInBackground()
If you want your scheduled task to run in the background without holding up other processes. runInBackground() will help you do this:
$schedule->command('your:command')->runInBackground();5. evenInMaintenanceMode()
You can guess what it does by its name. You can execute scheduled tasks even when your application is in maintenance mode.
$schedule->command('your:command')->evenInMaintenanceMode();
