websocket

问题 My Angular 2 app (coded in typescript) has a simple authentication scheme: User logs in: Server returns JSON Web Token (JWT) abc123... On every API call, the app sends the JWT in the Authorization header Server validates the JWT and grants access Now I'd like to add websockets. I'm wondering how to authenticate the user there. Since I don't control which headers are sent to the websocket server (WS), I cannot send the JWT. My idea so far (not yet implemented): Client opens websocket: let sock

问题 I'm using AsyncIO and the Websockets module to create two concurrent tasks in Python, each one connects to a websocket server and receives messages. I'm trying to create a system where, when a task did not receive messages for more than 4 seconds, it must close the connection and the task, but i'm having an hard time figuring that out. Can anyone help me out on this? Here is what i tried: async def connect(URI): async with websockets.client.connect(URI) as ws: LastUpdate = time.time() while

问题 I'm building a website, where my client communicates with the server over web sockets. I'm using nodejs on the backend and hence, the famous socket.io library for web sockets communication. The Problem Everything works fine with 1 to ~ 40 clients, after that the server starts disconnecting clients randomly. at the start I thought it is a scaling problem, maybe memory or something like that. However, after an extensive debugging session, I noticed that the reason for disconnection is ping

问题 I am following this tutorial Channels Tutorial Link My Goal was to make a simple asgi chat server. But It is showing weird behaviour. The message sent from one tab..should print "HI" in current tab..and also "HI" in the tab connected in the same room. but its printing the both "HI" in the current tab, no message is shown in the other tab connected in the same room. my consumers.py is simeple, just from the tutorials file... import json from asgiref.sync import async_to_sync from channels

问题 I have a WebSocket that I'm subscribing to and when an event comes in, I want to trigger a Google Cloud Function. Is this possible? For example, I'm listening to https://alpaca.markets/docs/api-documentation/api-v2/streaming/ And whenever I get trade_updates , I want to run a function on Google cloud Functions 回答1: All trigger types for Cloud Functions are listed here: https://cloud.google.com/functions/docs/calling Web Sockets are not directly supported as a trigger type. The closest I can

问题 I want to use linq to process events received via a websocket connection. This is what I have so far: private static void Main() { string WsEndpoint = "wss://push.planetside2.com/streaming?environment=ps2&service-id=s:quicktesting"; using (WebSocket ws = new WebSocket(WsEndpoint)) { ws.OnMessage += Ws_OnMessage; ws.Connect(); Console.ReadKey(); ws.Close(); } } private static void Ws_OnMessage(object sender, MessageEventArgs e) { Console.WriteLine(e.Data); } The first think that stumps me is
