Laravel 的定时任务

定时任务官方文档

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
