让你的 PHP 代码异步执行起来

Laravel 扩展包,基于 MySQL 后台任务管理工具,使用 Laravel Event Console 执行任务,负责管理和监控任务代码执行状态,让后台任务执行更简单。

任务选项

demo

Composer 安装

仓库源:https://packagist.org/packages/chester/background-mission

composer require chester/background-mission

MySQL Migration

创建数据表:不创建数据表是无法正常提交任务的

background-tasks/src/2018_11_14_104840_test.php

配置 Provider:

 Chester\BackgroundMission\Providers\MissionProvider::class

测试示例

假设后台需要导出1000万条数据,并下载这个文件,下面模拟导出 csv

// hello world. 测试10万条记录后台导出 csv 文件
public function helloWorld()
{
    $filename = storage_path('app') . '/' . date('YmdHis') . ".csv";
    $handle = fopen($filename, 'w');
    fwrite($handle, chr(0xEF) . chr(0xBB) . chr(0xBF));

    $cur_page = 0;
    fputcsv($handle, ['num', 'datetime']);
    do {
        $cur_page++;
        fputcsv($handle, [$cur_page, date('Y-m-d H:i:s')]);
        // 模拟10万条记录
        if ($cur_page >= 10000000) {
            break;
        }
    } while (true);
    return $this->response(1, "output target file dir: {$filename}");
}

运行测试示例:

$ php artisan mission:add

查看执行状态:

看到任务已经进入后台执行,并显示 Executing 状态。

➜  laravel git:(5.5) ✗ php artisan mission:records
+------------------+------------+--------+-----------+--------+--------------------+
| unique_id        | method     | type   | state     | params | content            |
+------------------+------------+--------+-----------+--------+--------------------+
| nauaxnrfnuflwcqn | helloWorld | system | executing | []     |                    |
+------------------+------------+--------+-----------+--------+--------------------+

经过一段时间后台,可以看到任务已经完成,并且输出 Content 包含文件 Csv 所在的路径,同时任务为 Success 状态。

➜  laravel git:(5.5) ✗ php artisan mission:records
+------------------+------------+--------+---------+--------+---------------------------------------------------------------------+
| unique_id        | method     | type   | state   | params | content                                                             | 
+------------------+------------+--------+---------+--------+---------------------------------------------------------------------+
| nauaxnrfnuflwcqn | helloWorld | system | success | []     | output target file dir: /www/laravel/storage/app/20181117151438.csv |
+------------------+------------+--------+---------+--------+---------------------------------------------------------------------+

自定义 Logic Functions

新建类:

<?php
namespace App;

use Chester\BackgroundMission\Logic;

class TestLogic extends Logic
{
    public function myTest()
    {
        sleep(20);
        return $this->response(1, 'my test');
    }
}

关联配置 config/const.php:

'background_logic' => '\App\TestLogic'

请求时,提交任务:

Route::get('bg-test', function () {
    app('chester.bg.queue')->push(['method' => 'myTest']);
});
