问题 When I try to send a socket message outside from the SocketIO event context, the message does not arrive at the client. Method outside of the context: @main.route('/import/event', methods=['POST']) def update_client(): from .. import socketio userid = request.json['userid'] data = request.json current_app.logger.info("New data: {}".format(data)) current_app.logger.info("Userid: {}".format(userid)) socketio.emit('import', data, namespace='/events', room=userid) return 'ok' I also tried: with

Exception gevent.hub.LoopExit: LoopExit('This operation would block forever',)

flask socketio emit to specific user

问题 I see there is a question about this topic, but the specific code is not outlined. Say I want to emit only to the first client. For example (in events.py): clients = [] @socketio.on('joined', namespace='/chat') def joined(message): """Sent by clients when they enter a room. A status message is broadcast to all people in the room.""" #Add client to client list clients.append([session.get('name'), request.namespace]) room = session.get('room') join_room(room) emit('status', {'msg': session.get(

Flask-Socketio takes extremely long to connect on Heroku

问题 All code works perfectly fine on my local machine, just not on Heroku. Have read through many issues on github / other errors on Flask-socketio and nothing seems to work. I left my browser running for about 20mins when using the eventlet setup and I saw the .on('connect') run correctly but none of the other parts of the code. Here's my current procfile: web: gunicorn -k geventwebsocket.gunicorn.workers.GeventWebSocketWorker -w 1 --chdir nickdima wsgi:app heroku features:enable http-session

How to send message from server to client using Flask-Socket IO

问题 I'm trying to create a python app that can send message from server to client. Currently I'm using this sample code from here. It's a chat app and it's working fine. I tried to modified the app and add a new function in the server side python code that will print a message "Dummy" into the client but seems like it didn't work. Here's my html code: index.html <body> <ul id="messages"></ul> <ul id="output"></ul> <form action=""> <input id="m" autocomplete="off" /><button>Send</button> </form>

using flask-migrate with flask-script, flask-socketio and application factory

问题 I'm creating an flask application with the application factory approach, but have an issue when using Flask-Migrate with socketio and flask-script. The problem is that I'm passing my create_app function to the Manager but I need to pass the app to my socketio.run() as well. And right now I can't seem to see a solution. Is there any way I can combine these two solutions? manage.py: #app = create_app(False) <--- Old approach #manager = flask_script.Manager(app) manager = flask_script.Manager

Python - Flask-SocketIO send message from thread: not always working

由 僤鯓⒐⒋嵵緔 提交于 2019-12-03 09:27:21
问题 I am in the situation where I receive a message from the client. Within the function that handles that request (@socketio.on) I want to call a function where some heavy work is done. This should not result in blocking the main thread and the client is thought to be informed once the work is done. Thus I start a new thread. Now I encounter a really strange behavior: The message never reaches the client. However, the code reaches that particular spot where the message is sent. Even more
