1. 安裝

composer require --prefer-dist yiisoft/yii2-queue

2. 配置，在 common/config/main.php 中配置

• redis作為驅(qū)動

return [
    'bootstrap' => [
        'queue', // 把這個(gè)組件注冊到控制臺
    ],
    'components' => [
        'redis' => [
            'class' => \yii\redis\Connection::class,
            // ...
        ],
        'queue' => [
            'class' => \yii\queue\redis\Queue::class,
            'as log' => \yii\queue\LogBehavior::class,//錯(cuò)誤日志 默認(rèn)為 console/runtime/logs/app.log
            'redis' => 'redis', // 連接組件或它的配置
            'channel' => 'queue', // Queue channel key
        ],
    ],
];

• File 作為驅(qū)動

return [
    'bootstrap' => [
        'queue', // 把這個(gè)組件注冊到控制臺
    ],
    'components' => [
        'queue' => [
            'class' => \yii\queue\file\Queue::class,
            'as log' => \yii\queue\LogBehavior::class,//錯(cuò)誤日志 默認(rèn)為 console/runtime/logs/app.log
            'path' => '@runtime/queue',
        ],
    ],
];

3. 新建 frontend/components/DownloadJob

class DownloadJob extends BaseObject implements \yii\queue\JobInterface
{
    public $url;
    public $file;
    
    public function execute($queue)
    {
        file_put_contents($this->file, file_get_contents($this->url));
    }
}

4. 控制臺

控制臺用于監(jiān)聽和處理隊(duì)列任務(wù)。
cmd 下 監(jiān)聽隊(duì)列

yii queue/listen

5. 添加到隊(duì)列

• 將任務(wù)添加到隊(duì)列:

Yii::$app->queue->push(new frontend\components\DownloadJob([
    'url' => 'http://example.com/image.jpg',
    'file' => '/tmp/image.jpg',
]));

• 將任務(wù)推送到隊(duì)列中延時(shí)5分鐘運(yùn)行:

Yii::$app->queue->delay(5 * 60)->push(new frontend\components\DownloadJob([
    'url' => 'http://example.com/image.jpg',
    'file' => '/tmp/image.jpg',
]));

6. 測試

執(zhí)行 5 中的程序，控制臺監(jiān)聽到，便會后臺自動 下載http://example.com/image.jpg到本地為/tmp/image.jpg
