Laravel 的定时任务
app/Console/Kernel.php
实现异常邮件发送
编写文件 app/Traits/ExceptionHandler.php
<?php /* @noinspection PhpUndefinedClassInspection */ /* @noinspection PhpUndefinedMethodInspection */ /* @noinspection PhpUnusedParameterInspection */ /* @noinspection PhpInconsistentReturnPointsInspection */ namespace App\Traits; use App; use App\Jobs\SendEmail; use Carbon\Carbon; use Exception; use Log; use Symfony\Component\Console\Input\InputInterface; use Symfony\Component\Console\Output\OutputInterface; use Throwable; const EMAIL_VIEW = 'email.exception'; const MARK = '定时任务运行异常'; trait ExceptionHandler { protected function execute(InputInterface $input, OutputInterface $output) { try { return $this->laravel->call([$this, 'handle']); } catch (Exception $exception) { $this->sendEmail((string)$exception, 'EXCEPTION'); } catch (Throwable $throwable) { $this->sendEmail((string)$throwable, 'THROWABLE'); } } private function getEnvName() { $envNames = [ 'local' => '本地环境', 'integration' => '集成环境', 'testing' => '测试环境', 'preview' => '预演环境', 'production' => '生产环境', ]; if ($envNames[App::environment()]) { return $envNames[App::environment()]; } return App::environment(); } private function sendEmail($messages, $errorType) { $emailAddresses = config('email-send.emails'); $subject = '服务监控-邻汇-'.$this->getEnvName(); $data = [ 'title' => '邻汇-'.$this->getEnvName(), 'time' => Carbon::now(), 'type' => $errorType, 'mark' => MARK, 'signature' => $this->signature, 'description' => $this->description, 'exception' => $messages, ]; try { dispatch(new SendEmail(EMAIL_VIEW, $data, $emailAddresses, $subject)); } catch (Exception $exception) { Log::info('邮件发送异常', [$exception->getMessage()]); } } }
关于 Trait 官网说明
Trait 是为类似 PHP 的单继承语言而准备的一种代码复用机制。Trait 为了减少单继承语言的限制，使开发人员能够自由地在不同层次结构内独立的类中复用 method。Trait 和 Class 组合的语义定义了一种减少复杂性的方式，避免传统多继承和 Mixin 类相关典型问题。
Trait 和 Class 相似，但仅仅旨在用细粒度和一致的方式来组合功能。 无法通过 trait 自身来实例化。它为传统继承增加了水平特性的组合；也就是说，应用的几个 Class 之间不需要继承。
在此处遇到的问题:dispatch 报错,但是 dispatch_now 可以使用
以下是当时获取的错误信息:
Exception: Serialization of 'Closure' is not allowed in E:\www\LinhuibaServer\vendor\laravel\framework\src\Illuminate\Queue\Queue.php:128 Stack trace: #0
解决方法:将 Exception $exception 转换成 String 类型
//$this->sendEmail($throwable, 'THROWABLE'); $this->sendEmail((string)$throwable, 'THROWABLE');
发件邮箱在配置文件里设置
<?php // 设置用于发送队列任务异常通知的用户邮件 return [ 'emails' => [ 'wts@tabll.cn', 'tabll@outlook.com', ] ];
添加至用于测试的任务
<?php namespace App\Console\Commands; use App\Traits\ExceptionHandler; use Illuminate\Console\Command; class Test extends Command { use ExceptionHandler; /** * The name and signature of the console command. * @var string */ protected $signature = 'test'; /** * The console command description. * @var string */ protected $description = '测试任务运行异常'; /** * Create a new command instance. * @return void */ public function __construct() { parent::__construct(); } /** * Execute the console command. * @return mixed */ public function handle() { $this->info('开始ing'); $g = (int)'你好'; $g = $g->toDate(); } }
需要在每一个任务中加上它
use ExceptionHandler;
效果
这样就完成了具有通知是哪一个运行环境，时间，名称，描述，异常内容的功能
