一、事件監(jiān)聽

流程：

1.1 創(chuàng)建event

php artisan make:event UserLogin

LoginController.php

    /**      * The user has been authenticated.      *      * @param  IlluminateHttpRequest  $request      * @param  mixed  $user      * @return mixed      */     protected function authenticated(Request $request, $user)     {         event(new UserLogin($user));     }

1.2 創(chuàng)建listener

1.2.1 方式一：手動(dòng)創(chuàng)建

php artisan make:listener EmailAdminUserLogin --event=UserLogin

1.2.2 方式二：推薦如下方式：自動(dòng)生成事件和監(jiān)聽

//應(yīng)用程序的事件監(jiān)聽器映射  class EventServiceProvider extends ServiceProvider {     /**      * The event listener mappings for the application.      *      * @var array      */     protected $listen = [         'AppEventsUserLogin' => [             'AppListenersUserLoginEmailAdminUserLogin',             'AppListenersUserLoginTraceUser',             'AppListenersUserLoginAddUserLoginCounter',         ],         'AppEventsUserLogout' => [             'AppListenersUserLogoutEmailAdminUserLogout',             'AppListenersUserLogoutTraceUser',         ],     ];      /**      * Register any events for your application.      *      * @return void      */     public function boot()     {         parent::boot();          Event::listen('event.*', function ($eventName, array $data) {             //         });     } }

生成事件 & 監(jiān)聽器：php artisan event:generate

二、Laravel 的任務(wù)調(diào)度（計(jì)劃任務(wù)）功能 Task Scheduling

2.1 call方式

protected function schedule(Schedule $schedule)     {         $schedule->call(function (){             Log::info('我是call方法實(shí)現(xiàn)的定時(shí)任務(wù)');         })->everyMinute();     }

執(zhí)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 AppConsoleCommands;  use IlluminateConsoleCommand;  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()     {         //書寫處理邏輯         Log::info('早上好，用戶');     } }

Kernel.php

protected function schedule(Schedule $schedule) {     $schedule->command('message:hi')              ->everyMinute(); }

執(zhí)行：php artisan schedule:run

三、隊(duì)列任務(wù)

3.1 驅(qū)動(dòng)的必要設(shè)置

QUEUE_DRIVER=database

如：數(shù)據(jù)庫驅(qū)動(dòng)

php artisan queue:table  php artisan migrate

3.2 創(chuàng)建任務(wù)

生成任務(wù)類：

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 分發(fā)任務(wù)

你寫好任務(wù)類后，就能通過 dispatch 輔助函數(shù)來分發(fā)它了。唯一需要傳遞給 dispatch 的參數(shù)是這個(gè)任務(wù)類的實(shí)例：
利用模型工廠生成30個(gè)用戶：

    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');

數(shù)據(jù)庫表jobs生成5個(gè)隊(duì)列任務(wù)：

3.4 運(yùn)行隊(duì)列處理器

php artisan queue:work

Tips：要注意，一旦 queue:work 命令開始，它將一直運(yùn)行，直到你手動(dòng)停止或者你關(guān)閉控制臺(tái)

處理單一任務(wù)：你可以使用 --once 選項(xiàng)來指定僅對(duì)隊(duì)列中的單一任務(wù)進(jìn)行處理

php artisan queue:work --once

拓展：使用 Beanstalkd 管理隊(duì)列，Supervisor 則是用來監(jiān)聽隊(duì)列的任務(wù)，并在隊(duì)列存在任務(wù)的情況下自動(dòng)幫我們?nèi)?zhí)行，免去手動(dòng)敲 php artisan 的命令，保證自己的隊(duì)列可以正確執(zhí)行
