有什么方法可以从网页运行内部 python 脚本？

Question

I finally made a project that I wanted to make since a long time:

I'm using an Arduino Uno to replace my PC power button (with a simple relay) and that Arduino Board is connected to a Raspi 3 for network connection purposes

My wish is to do a webpage (or a API-Like request) that at a touch of a button (preferably in a password-protected page) It'll power the PC on

I know how to code in Python, and my script to control the Arduino is already done but I can't find a way to run, only server-side, a Python Script from a button in a webpage

I found that CherryPy framework but I don't think it'll suit my needs

Can someone give me any ideas about that please?

Answer 1

As already mentioned by @ForceBru, you need a python webserver.

If this can be useful to you, this is a possible unsecure implementation using flask:

from flask import Flask
from flask import request

app = Flask(__name__)

@app.route('/turnOn')
def hello_world():
    k = request.args.get('key')
    if k == "superSecretKey":
        # Do something ..
        return 'Ok'
    else:
        return 'Nope'

If you put this in an app.py name file and, after having installed flask ( pip install flask ), you run flask run you should be able to see Ok if visiting the url http://localhost:5000/turnOn?key=superSecretKey .

You could write a brief html gui with a button and a key field in a form but I leaves that to you (you need to have fun too.). To avoid potential security issues you could use a POST method and https. Look at the flask documentation for more infos.
