I'm trying to incorporate socketio with my flask project. Right now I am trying to get a simple "Connected" or "Disconnected" output from the server. However when I run the app script with "python app.py" I don't get these messages nor any errors pointing me in any direction.
I never thought I would miss errors!
app.py
from flask import Flask, render_template, request, url_for, copy_current_request_context
from flask_socketio import SocketIO, emit
import logging
logging.basicConfig()
app = Flask(__name__)
app.config['SECRET_KEY'] = 'secret!'
app.config['DEBUG'] = True
socketio = SocketIO(app)
@app.route('/scan/')
def waitForRFID():
return render_template('scan.html')
@socketio.on('connect', namespace='/test')
def test_connect():
print('Client connected')
@socketio.on('disconnect', namespace='/test')
def test_disconnect():
print('Client disconnected')
if __name__ == '__main__':
socketio.run(app)
scan.html
<!doctype html>
<meta name="viewport" content="width=device-width, initial-scale=1">
<head>
<script src="//cdnjs.cloudflare.com/ajax/libs/socket.io/1.3.6/socket.io.min.js"></script>
<script src="{{ url_for('static', filename = 'js/scan.js') }}"></script>
<link rel=stylesheet type=text/css href="{{ url_for('static', filename='css/scan.css') }}" />
</head>
scan.js
$(document).ready(function(){
//connect to the socket server.
var socket = io.connect('http://' + document.domain + ':' + location.port + '/test');
});
When I run the app.py file and visit "127.0.0.1:5000/scan/", I get the following output in terminal:
127.0.0.1 - - [2018-02-11 16:42:10] "GET /scan/ HTTP/1.1" 200 812 0.010323
The web-page loads properly, and I get the same output if I run this in or out of a virtual environment.
With a setup as simple as this, what could be wrong? Thank you in advance!
