Get variables from post method on Python

I made a python script that run some tasks, but i wanted it to launch when a client (frontend form) send a POST request to the server. So then I can get the variables from the client and run my script using that variable.

I think I will need to define a server on my python script that accept a post request, but I don't know where to start here. Can you help me a little bit with this?

you need to make an Ajax call to your python server to request information from javascript.

I have created a simple Flask server which appends person information into the list which is received from the client side.

Here's theapp.py which contains the flask Python server:

import os

import uuid



from flask import Flask, jsonify, request

from flask_cors import CORS



# instantiate the app

app = Flask(__name__)

app.config.from_object(__name__)



# enable CORS

CORS(app)



#static list containing persons

persons = 



#test check route

@app.route('/status', methods=['GET'])

def status():

    return jsonify(dict({ 'message': 'Hello world'}))





@app.route('/person', methods=['POST'])

def add_person():

    post_data = request.get_json()

    response_object = dict({

            'id': uuid.uuid4().hex,

            'name': post_data.get('name'),

            'age': post_data.get('name')

        })

    persons.append(response_object)

    return jsonify(response_object), 201





@app.route('/person', methods=['GET'])

def get_persons():

    return jsonify(persons), 200



@app.route('/person/<person_id>', methods=['GET'])

def get_person(person_id):

    person = list(filter(lambda x: x['id'] == person_id, persons))

    return jsonify(person), 200



if __name__ == '__main__':

    app.run(debug=True)

Save the script and run it using:

python app.py

This is a sample form that will post the name and age fields to your flask API:

// Write the following in index.js

window.onload = () => {





  document.querySelector('#btnSubmit').addEventListener('click', function(event) {



    const pName = document.querySelector('#pName').value;

    const pAge = document.querySelector('#pAge').value;



    if (!pName || !pAge) {

      alert('Please enter all fields to continue!');

      return;

    }



    const objectToSend = {

      name: pName,

      age: pAge

    };



    fetch('http://localhost:5000/person', {

        method: 'POST',

        mode: 'cors',

        body: JSON.stringify(objectToSend)

        headers: new Headers({

          'Content-Type': 'application/json',

          'Access-Control-Allow-Origin': '*'

        })

      })

      .then(function(response) {

        return response.json()

      })

      .then(function(data) {

        console.log(data);

      })

      .catch(function(err) {

        console.err(err);

      });



  });



}
