Flask SocketIO send message from server to room
In my app , I need the client to join a room so that it may then receive messages from my server .
Server Code
@socketio.on('join', namespace='/test')
def join(message):
join_room(message['room'])
room = message['room']
emit('my response', {'data': 'Entered the room ' + message['room']}, room=room)
@app.route('/scan/user/<int:user_id>/venue/<int:venue_id>', methods = ['POST'])
@auth.login_required
def scan_tablet_user_func(user_id, venue_id):
room = 'venue_' + str(venue_id)
socketio.emit('my response', {'data': json.dumps(my_info, ensure_ascii=False)}, room=room)
Client Code
$('form#join').submit(function(event) {
socket.emit('join', {room: $('#join_room').val()});
return false;
});
As soon as the webpage loads, I enter "venue_1" into the webpage form entitled "join" .
The variable room on the server side is also set to "venue_1" .
The issue is that when I call the API /scan/user/... , nothing appears on my client . However,
emit('my response', {'data': 'Entered the room ' + message['room']}, room=room)
does appear correctly.
I think that you need to supply a namespace parameter to your emit in the API call, since you have defined a namespace.
socketio.emit('my response', {'data': json.dumps(my_info, ensure_ascii=False)}, room=room, namespace='/test')
If you don't supply the namespace you will use the default one.
