How to get the position data from the joystick to the flask server?

Solution

from flask import Flask
from flask import (
    jsonify,
    render_template,
    request
)

app = Flask(__name__)

@app.route('/')
def index():
    return render_template('index.html')

@app.route('/process', methods=['POST'])
def process():
    data = request.get_json()
    print(data)
    return jsonify(message='Success', stickdata=data)

from flask import Flask
from flask import render_template
from flask_socketio import SocketIO

app = Flask(__name__)
app.secret_key = 'your secret here'
socketio = SocketIO(app)

@app.route('/')
def index():
    return render_template('index.html')

@socketio.on('stick')
def handle_stick(data):
    print(data)

if __name__ == '__main__':
    socketio.run(app)
