Laravel 5.2如何在linux上的cron / php命令行上运行路由？

Question

Despite going through documentation about commands (is that how you can run php on command line on laravel?) I just don't get it at all.

For example I can run php script on command line on linux:

php /path/to/my/phpfile.php

How on earth I can manage to do this on laravel? Let's say I have a route to

Route::get('/runthis', array('as' => 'runthis', 'uses' => 'Controller@runthis'));

How to run this on cron?

Answer 1

I would actually take a different approach to this personally. I would leverage the schedule method off of the Kernel and simply add * * * * * php /path/to/artisan schedule:run It may look something like this:

In:

App
    |- Console
        |- Kernel.php

The structure of this file would look something like this:

class Kernel extends ConsoleKernel {
    protected $commands = [

    ];

    /* ... */
    protected function schedule(Schedule $schedule){
        $schedule->call(function(){
            //call your logic here
        })->cron('* * * * *');
    }
}

Now just add the appropriate entry to your crontab and you're good to go.

Updated with Cron Information

cron tasks (AFAIK) don't support the seconds granularity. Instead, you would need to execute the cron task 30 times 2 seconds after the previous in order to achieve the "every 2 seconds" cron job. There's no other way that I know of to achieve this.

Here is a little diagram that I've found extremely useful in explaining what the asterisk mean:

 * * * * *  command to execute
 ┬ ┬ ┬ ┬ ┬
 │ │ │ │ │
 │ │ │ │ │
 │ │ │ │ └───── day of week (0 - 7) (0 to 6 are Sunday to Saturday, or use     names; 7 is Sunday, the same as 0)
 │ │ │ └────────── month (1 - 12)
 │ │ └─────────────── day of month (1 - 31)
 │ └──────────────────── hour (0 - 23)
 └───────────────────────── min (0 - 59)

And here's a list of your options you can use instead of cron as shortcuts:

->cron('* * * * * *');  Run the task on a custom Cron schedule
->everyMinute();    Run the task every minute
->everyFiveMinutes();   Run the task every five minutes
->everyTenMinutes();    Run the task every ten minutes
->everyThirtyMinutes(); Run the task every thirty minutes
->hourly(); Run the task every hour
->daily();  Run the task every day at midnight
->dailyAt('13:00'); Run the task every day at 13:00
->twiceDaily(1, 13);    Run the task daily at 1:00 & 13:00
->weekly(); Run the task every week
->monthly();    Run the task every month
->monthlyOn(4, '15:00');    Run the task every month on the 4th at 15:00
->quarterly();  Run the task every quarter
->yearly(); Run the task every year
->timezone('America/New_York'); Set the timezone

Answer 2

You wouldn't typically run a controller function in a cron. You'd put the runthis logic in an Artisan command , then schedule it to run with Laravel's scheduler.

Answer 3

如果你使用cron安排，你可以使用curl "url"来调用路由
