Flask-SocketIo | After logging in Chrome dosen't return session['name'] value but Firefox does.

[KarteekAti]

When I log in using User-id Chrome doesn't return the Users name using session['name'], which I provided using the flasks session. But firefox does.

Python

 @app.route('/get_name',methods=['GET'])
def get_name():
	data = {'name' : ''}
	if NAME_KEY in session:
		data = {'name':session['name']}
	return jsonify(data)	

JS

async function get_Name(){
    return fetch("/get_name")
    .then(function (response) {
        return  response.json();   
       })
       .then(function (text) {  
         return text["name"];
       });
}
socket.on('connect', async function() {
var usr_name =  await get_Name();
console.log(usr_name);
if(usr_name != ''){
    var data = {
        'name': usr_name,
        'msg': 'User has connected!'
    };
    socket.emit('message',data);	
}

Chrome returns an empty username, whereas Firefox returns logged username

I'm not sure if this is the problem or not, but your get_name() function looks very strange to me. Here is a correct version of it:

async function get_Name(){
    const response = await fetch("/get_name");
    const text = await response.json();
    return text["name"];
}

You may want to add a print statement in the server to verify if the server has the correct name in the session or not. If it does, then this is a problem with your front end, unrelated to Flask-SocketIO.

I'm sorry but you are providing no additional information, so there is nothing else I can tell you. If you think this is a bug in this package, then build a complete application with server and client and I'll test it here.

Sorry, but I have started making some changes to server. Trying using Ajax.

You don't understand. If (only if) you think this is a bug in this package, then please create a short example that reproduces the problem and send me the source code so that I can investigate and fix the bug.

Oh, ok my bad. I'm not sure is this related to front-end or Socketio. I'll try to investigate more.
