从Codeigniter执行Python文件 [英] Executing a Python file from Codeigniter

问题描述

从Codeigniter控制器的功能执行Python文件时遇到麻烦.

I have some trouble to execute a Python file from a Codeigniter controller's function.

〜/application/controllers/Lights.php:

~/application/controllers/Lights.php :

header("Access-Control-Allow-Origin: *");
class Lights extends CI_Controller {
    public function __construct() {
        parent::__construct ();
        $this->load->helper ( array ('url', 'form') );
    }
    public function turnOn() {
        system('sudo python test.py > /dev/null 2>/dev/null &');
    }
}

但是当我尝试执行系统调用时，例如:

but when I try to execute a system call, like :

system("sudo gpio mode 15 out");

这很好用.

推荐答案

为 python 二进制文件和 script 提供完整路径，即:

Provide the full path to python binary and script, i.e.:

system('/full/path/to/python /full/path/to/test.py > /dev/null 2>/dev/null &');

如果您的apache用户( apache / www-user )，则可以忽略完整路径.

If the python binary is already on the PATH of your apache user (apache/www-user), you may ignore the full path.
