> 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
----

[](#任务选项)

参数名称是否必填描述method是任务执行方法 Logicparams否执行 Method 所需要的参数type否任务分类，自定义字符串creator否任务提交者，自定义字符串[![demo](demo1.png)](demo1.png)

```

配置 Provider：

```

测试示例
----

[](#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 |
+------------------+------------+--------+---------+--------+---------------------------------------------------------------------+
```
