websocket

问题 I am following the quick-start guide on Spring websocket with sockJs and Stomp here: https://spring.io/guides/gs/messaging-stomp-websocket/ At this point, my code looks like to one from guide and works as intended. I have a controller class with a method accepting incoming messages and sending them back to all who subscribed on the topic. What I want to do, is to change the code, so my @MessageMapping annotated method sends response to all subscribers excluding the one who send the message to

问题 I am building a messaging system in Django, using web-socket to receive the message. Here is my tryouts, from channels.consumer import AsyncConsumer from channels.db import database_sync_to_async class ChatConsumer(AsyncConsumer): async def websocket_connect(self, event): print("connected", event) await self.send({ "type": "websocket.accept" }) async def websocket_receive(self, event): print("receive", event) message = event['text'] obj = await self.create_obj(message=message) print('Created.

问题 What is the difference between: socket.broadcast.to().emit() and socket.to().emit() Here on the socket.io cheat sheet it says socket.to('game').emit('nice game', "let's play a game"); // sending to all clients in 'game' room except sender Then in this tutorial blog it says: socket.broadcast.to('game').emit('message', 'nice game'); //sending to all clients in 'game' room(channel) except sender socket.to('game').emit('message', 'enjoy the game'); //sending to sender client, only if they are in

问题 I have the demo laravel websockets app up and running on a centos server, having followed the basic installation instructions here: https://github.com/beyondcode/laravel-websockets-demo I've also got it set up and running in Nginx (so am not running php artisan serve) However, I can't get the php artisan websockets:serve command to work. on the cli it says: "Starting the WebSocket server on port 6001..." And I can get into mydomain/laravel-websockets and see the admin console, but it can't

问题 I use websockets to receive video frames. Image is encoded in base64 mimetype image/jpeg. I'm trying to convert image to np.ndarray. When I read image file code works correct. But when I'm trying to read image from socket stream, issue is occured. image_data = base64.b64decode(part.encoded_image) np_array = np.frombuffer(image_data, np.uint8) image = cv2.imdecode(np_array, cv2.IMREAD_UNCHANGED) In docs cv2.imdecode() returns None in case when image is short or corrupted. My image is in HD

问题 When I run my project, I got an exception error but it does not have a clear message. I only have this kind of the main body error I can access websocket admin page at http://127.0.0.1:8000/laravel-websockets but when i go http://127.0.0.1:8000/ i got errors below.

问题 My goal is to authenticate the WebSocket CONNECT frame. I wish to be able to initialize Authentication user = ... by using X-Auth-Token . TL:DR I use the X-Auth-Token header. How the current authentication works: User hit POST /login endpoint with Form Data username and password . The response header will contain the key X-Auth-Token .
