如何从PHP webhook调用shell_exec（）？

Question

I'm having a major issue and I can't find a solution. I currently have a PHP script that accepts a webhook (HTTP POST) as a trigger. Based on variables contained in the POST, an exec('python script') is supposed to run, and return some variables. It works fine when I run it from the command line it works fine, but when I try to trigger the script from any type of HTTP request, the exec() function does not run. Here is the section of code that is affected:

$command = shell_exec('python C:\\xampp\\cgi-bin\\SECpull.py');

$company_dump = print_r($command, TRUE);
$fp = fopen('retvals.txt', 'w');
fwrite($fp, $company_dump);
fclose($fp);

If it isn't possible to have an exec() function in a PHP script that is triggerd by an HTTP POST, then how should I go about this?

Problem

As Robbie Averill mentioned, most probably you have a permission issue and you can fix it by adding additional permissions to user that is used to run the web server. However, I think it is not a good style to mix php with python , and if you cannot re-write SECpull.py to php , then better do everything in python .

I suggest you to use Flask for that.

Sample

# server.py
from flask import Flask
app = Flask(__name__)

# Setup custom route here
@app.route("/") 
def index():
    # Add SECpull.py logic here.
    return "Welcome To Python Server!"

if __name__ == "__main__":
    app.run()

Setup

$ pip install Flask
$ python server.py
