1. 이벤트 모니터링
Process:
1.1 이벤트 생성
php artisan make:event UserLogin
LoginController.php
/**
* The user has been authenticated.
*
* @param \Illuminate\Http\Request $request
* @param mixed $user
* @return mixed
*/
protected function authenticated(Request $request, $user)
{
event(new UserLogin($user));
} 1.2 생성 리스너
1.2 .1 방법 1: 수동으로 생성
php artisan make:listener EmailAdminUserLogin --event=UserLogin
1.2.2 방법 2: 다음 방법을 권장합니다: 자동으로 이벤트 및 리스너 생성
//应用程序的事件监听器映射
class EventServiceProvider extends ServiceProvider
{
/**
* The event listener mappings for the application.
*
* @var array
*/
protected $listen = [
'App\Events\UserLogin' => [
'App\Listeners\UserLogin\EmailAdminUserLogin',
'App\Listeners\UserLogin\TraceUser',
'App\Listeners\UserLogin\AddUserLoginCounter',
],
'App\Events\UserLogout' => [
'App\Listeners\UserLogout\EmailAdminUserLogout',
'App\Listeners\UserLogout\TraceUser',
],
];
/**
* Register any events for your application.
*
* @return void
*/
public function boot()
{
parent::boot();
Event::listen('event.*', function ($eventName, array $data) {
//
});
}
}
이벤트 및 리스너 생성: php artisan event:generate php artisan event:generate
二、Laravel 的任务调度（计划任务）功能 Task Scheduling
2.1 call方式
protected function schedule(Schedule $schedule)
{
$schedule->call(function (){
\Log::info('我是call方法实现的定时任务');
})->everyMinute();
}
执行：php artisan schedule:run
2.2 crontab方式
2.2 command方式
生成命令：php artisan make:command SayHello
<?php namespace App\Console\Commands;
use Illuminate\Console\Command;
class SayHello extends Command
{
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'message:hi';
/**
* The console command description.
*
* @var string
*/
protected $description = 'Command description';
/**
* Create a new command instance.
*
* @return void
*/
public function __construct()
{
parent::__construct();
}
/**
* Execute the console command.
*
* @return mixed
*/
public function handle()
{
//书写处理逻辑
\Log::info('早上好，用户');
}
}Kernel.php
protected function schedule(Schedule $schedule)
{
$schedule->command('message:hi')
->everyMinute();
}执行：php artisan schedule:run
三、队列任务
3.1 驱动的必要设置
QUEUE_DRIVER=database
如：数据库驱动
php artisan queue:table php artisan migrate
3.2 创建任务
生成任务类：
php artisan make:job SendReminderEmail
class SendReminderEmail implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
public $user;
/**
* Create a new job instance.
*
* @param User $user
*/
public function __construct(User $user)
{
$this->user = $user;
}
/**
* Execute the job.
*
* @return void
*/
public function handle()
{
\Log::info('send reminder email to user' . $this->user->email);
}
}3.3 分发任务
你写好任务类后，就能通过 dispatch 辅助函数来分发它了。唯一需要传递给 dispatch 的参数是这个任务类的实例：
利用模型工厂生成30个用户：
public function store(Request $request)
{
$users = User::where('id','>',24)->get();
foreach ($users as $user){
$this->dispatch(new SendReminderEmail($user));
}
return 'Done';
}Route::get('/job', 'UserController@store');数据库表jobs生成5个队列任务：
3.4 运行队列处理器
php artisan queue:work
Tips：要注意，一旦 queue:work 命令开始，它将一直运行，直到你手动停止或者你关闭控制台
处理单一任务：你可以使用 --once 选项来指定仅对队列中的单一任务进行处理
php artisan queue:work --once
拓展：使用 Beanstalkd 管理队列，Supervisor 则是用来监听队列的任务，并在队列存在任务的情况下自动帮我们去执行，免去手动敲 php artisan
