Question

我对Gearman很陌生。我正在尝试编写PHP脚本以从URL下载脚本并将其上传到用户的Google驱动器。某种备份脚本。

我想做的是在该过程中调用启动Gearman Worker进程，以首先将图像从源下载到temp目录，然后将其上传到Google驱动器。这是脚本：

    <?php
require_once "../classes/drive.class.php";
    $worker = new GearmanWorker();
    $worker-> addServer('localhost');
    $worker->addFunction('init', 'downloader');
    $worker->addFunction('upload', 'uploader');
    function downloader($job){
        // downloads the images from facebook
        $data = unserialize($job->workload()); // receives serialized data
        $url = $data->url;
        $file = rand().'.jpg';
        $saveto  = __DIR__.'/tmp/'.$file;
        $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
        $raw=curl_exec($ch);
        curl_close ($ch);
        if(file_exists($saveto)){
            unlink($saveto);
        }
        $fp = fopen($saveto,'x');
        fwrite($fp, $raw);
        fclose($fp);
        // create a gearman client to upload image to google drive
        $client = new GearmanClient();
        $client->addServer();
        $data['file'] = $saveto;
        return $client->doNormal('upload', serialize($data)); // ensure synchronous dispatch
        // can implement a post request return call, to denote a loading point on a loading bar.
    }
    function uploader($job){
        $data = unserialize($job->workload());
        $file = $data->file;
        $google = $data->google; 
        $drive = new Drive($google);
        return $drive->init($file); // returns boolean
    }
?>

问题是，当我使用php worker.php &启动worker时，该过程开始，但是一旦我开始在控制台上执行其他操作并在控制台上打印消息“ DONE”，就会杀死自己。

如何执行我的流程？并保持该脚本运行？

这是一个模糊的解释，但请尝试研究并提供帮助。我真的是齿轮工新手。

谢谢

您缺少工作循环。

// Create the worker and configure it's capabilities
$worker = new GearmanWorker();
$worker->addServer('localhost');
$worker->addFunction('init', 'downloader');
$worker->addFunction('upload', 'uploader');

// Start the worker
while($worker->work());

// Your function definition
function downloader($job) {
    // do stuff with $job
}

function uploader($job) {
    // do stuff with $job
}
