Laravel crontab -e 无法识别



这是我第一次设置 Cron 作业,我无法让它自动调度命令。

所以我有一个命令:

public function handle()
{
    $client = new Client();
$crawler = $client->request('GET', 'http://www.oldham-chronicle.co.uk/news-features');
$crawler->filter('div[id=content]>.homefeature')->each(function ($node, $key) {
    $title = $node->filter('.plain')->text();
    $datepublished = $node->filter('.dateonline')->text();
    $description = $node->filter('.teaser-link')->text();
    $link = $node->filter('a')->link();
    $link_r = $link->getUri();
    $image = $node->filter('img')->image();
    $image_s = $image->getUri();
    $filename = basename($image_s);
    $image_path = ('news-gallery/' . $filename);
    Image::make($image_s)->save(public_path('news-gallery/' . $filename));
    $id = 1+ $key + 1;
    $news = News::where('id', $id)->first();
    // if news is null
    if (!$news) {
        $news = new News();
    }
    $news->title = $title;
    $news->datepublished = $datepublished;
    $news->description = $description;
    $news->link = $link_r;
    $news->image = $image_path;
    $news->save();
});
$crawler->filter('div[id=content]>.teaser-50')->each(function ($node, $key) {
    $title = $node->filter('.plain')->text();
    $datepublished = $node->filter('.dateonline')->text();
    $description = $node->filter('.teaser-link')->text();
    $link = $node->filter('a')->link();
    $link_r = $link->getUri();
    $image = $node->filter('img')->image();
    $image_s = $image->getUri();
    $filename = basename($image_s);
    $image_path = ('news-gallery/' . $filename);
    Image::make($image_s)->save(public_path('news-gallery/' . $filename));
    $id = 1+ $key + 1;
    $news = News::where('id', $id)->first();
    // if news is null
    if (!$news) {
        $news = new News();
    }
    $news->title = $title;
    $news->datepublished = $datepublished;
    $news->description = $description;
    $news->link = $link_r;
    $news->image = $image_path;
    $news->save();
    $this->info('Scraping done succesfully');
});
}

内核文件:

protected $commands = [
    'AppConsoleCommandsNewsScrape'
];
/**
 * Define the application's command schedule.
 *
 * @param  IlluminateConsoleSchedulingSchedule  $schedule
 * @return void
 */
protected function schedule(Schedule $schedule)
{
    $schedule->command('scrape:news')
             ->hourly();
}

我转到一个项目文件夹,键入 crontab -e,我得到:

"crontab"不被识别为内部或外部命令,可操作的程序或批处理文件。

如何解决这个问题?请记住,这是我第一次使用它

在生产中,您必须设置以下 crontab:

文档:https://laravel.com/docs/5.4/scheduling

* * * * * php /path-to-your-project/artisan schedule:run >> /dev/null 2>&1

请务必根据需要更新/path-to-your-project/

这将每分钟运行一次 php artisan schedule:run 命令,该命令将检查是否有任何调度程序需要运行。

我不知道如何为Windows设置它,但是我建议使用开发环境Homestead,它使用Vagrant和Virtual Box。它将为您提供一个 Ubuntu VM,因此您可以使用 crontab。

Windows 上

没有 crontab 命令,这适用于您的生产环境,但在 Windows 上则不行。

等效项在命令行中,键入 at /? 以获得一些帮助,我无法帮助您,因为我从未使用过它
