I need help in debugging -the Same Origin Policy disallows reading the remote resource at https://some-domain.com. (Reason: CORS request did not succeed) in python flask-socketio error.
I am working on a chat application using python flask-socketio. In previously I have created that application in local and it works fine as expected, while I move the below code to the server it shows the above error. The client code runs in the https servers and server code also runs on the https server I don't know why that error shows.
I have attached my code below and please give a better solution to me.
server.py
import json
import os
from flask import Flask, render_template, request,session
from flask_socketio import SocketIO, send, emit
from datetime import timedelta,datetime
from flask_cors import CORS
app = Flask(__name__)
app.config['SECRET_KEY'] = 'secretkey'
app.config['DEBUG'] = True
app.config['CORS_HEADERS'] = 'Content-Type'
cors = CORS(app, resources={r"/*": {"origins": "*"}})
socketio = SocketIO(app)
users = {}
@app.before_request
def make_session_permanent():
session.permanent = True
app.permanent_session_lifetime = timedelta(minutes=1)
@app.route('/')
#@cross_origin(origin='*',headers=['Content- Type','Authorization'])
def index():
return render_template('index.html')
@socketio.on('connect')
def connect():
print("connected");
@app.route('/orginate')
def orginate():
socketio.emit('server orginated', 'Something happened on the server!')
return '<h1>Sent!</h1>'
@socketio.on('username')
def receive_username(username):
users[username] = request.sid
#users.append({username : request.sid})
#print(users)
emit('userList', users, broadcast=True)
print('Username added!')
print(users)
if _name_ == '__main__':
socketio.run(app,host='xxx.xxx.xx.x',port=5001)
client.js
var socket = io.connect("https://xxx.xxx.xx.x:5001/",{secure:false});
Screenshot 1: This screenshot explains the access-control-allow-orgin works fine for images under static folder in flask framework
Screenshot 2:
This screenshot explains there is no access-control-orgin for socket call
