从Laravel运行Python脚本

Question

I am trying to build a system in Laravel from which I am able to call some python scripts. Starting with https://github.com/maurosoria/dirsearch , I have placed the python script with the same machine and tried to run on api call.

If I run shall_exec('ls -la'); it runs perfectly and returns me result. But when I run the following command, the execution ends and no output.

shall_exec("python3 dirsearch-master/dirsearch.py -u https://www.yahoo.com/ -e *");

Then I used https://symfony.com/doc/current/components/process.html and try the same steps

use Symfony\Component\Process\Exception\ProcessFailedException;
use Symfony\Component\Process\Process;

$process = new Process("python3 dirsearch-master/dirsearch.py -u https://www.yahoo.com/ -e *");
$process->run();

// executes after the command finishes
if (!$process->isSuccessful()) {
    throw new ProcessFailedException($process);
}

echo $process->getOutput();

In this case also the $process->run(); returns me no result.

You can use the Custom Artisan command if you want. Create a new Artisan Command by running php artisan make:command COMMAND_NAME . it will create a new Artisan command in app\\Console\\Commands directory of your project.

class Analytics extends Command{

    protected $signature = 'Run:Shell {path} {u} {e}';

    protected $description = 'Run Python Via Server Shell';

    public function __construct(){
        parent::__construct();
    }

    public function handle(){
        $output = shall_exec("python3 ".$this->argument('path')." -u ".$this->argument('u')." -e ".$this->argument('e'));
        $this->info($output);
    }
}

Now, you can run the artisan command as php artisan Run:Shell path='dirsearch-master/dirsearch.py' u='https://www.yahoo.com/' e='*' and the output will be printed to CMD. You can also run this Artisan command from any controller you want as,

// Taking Inputs from Request in Controller
Artisan::call("Run:Shell", ['path' => $request->input('path'), 'u' => $request->input('u') , 'e' => $request->input('e')]); 

In fact, you can make the entire wrapper to run the python on your server-side using Laravel. But you should have the python3 installed and configured on your server before running it.
