websocket

问题 Lets say that i make a websocket server chat (node.js + socket.io). How would i store the chat messages, so that when a "new" user joins the chat, he will be seeing old chat messages, and not just the ones which has been sent while hes in the chat. Should the data be stored in variables in the server? Something like: var io = require('socket.io').listen(80); var saveData = { }; io.sockets.on('connection', function (socket) { socket.emit('news', { hello: 'world' }); socket.on('my other event',

问题 My API Manager tool mandates that i should pass the Authorization Bearer access token with the websocket invocation call. They are providing samples of java code where they do that. The bearer token is set like ("Authorization", "Bearer e2238f3a-e43c-3f54-a05a-dd2e4bd4631f") .How can i do that in javascript? // HttpResponseDecoder to WebSocketHttpResponseDecoder in the pipeline. final WebSocketClientHandler handler = new WebSocketClientHandler( WebSocketClientHandshakerFactory .newHandshaker

问题 I am using STOMP over websockets with spring boot. Is there a possibility to send a message to a specific subscription? I subscribe to the STOMP endpoints using a STOMP header containing an id field according to the stomp documentation I want this id to be used to determine the clients who should receive a message, but spring seems not to use this id. I can not just use sendToUser because two clients can have the same user id e.g. if a user has two opened browser windows. Only one specific

问题 I'm carrying this on from this question, since the focus has changed. I am trying to send string data from a vapor server over a websocket. The client side is where the main question is. This code successfully receives the string, which is expected to be JSON (but not absolutely guaranteed -- out of scope). switch message { case .data(let data): print("data: \(data)") case .string(let str): // let data = str.message(using: .utf8) let jsonData = Data(str.utf8) print("string: \(jsonData)") do {

问题 There question about this before, the answer is no. But now, with browserify/webpack, can I just write code like I would on server and it will run in browser, or is there any restriction that would make this impossible? 回答1: No, you cannot. Starting a server in a browser requires access to low level functionality that simply to does not exist in a browser. Browserify cannot add fundamental low-level features to the browser that it does not have that would require additional native code

问题 How can I kill a Websocket connection? I'm not talking about closing the connection on either end but interrupting it "in the middle". I need to test some application logic that must happen on a reconnect (which is handled through SocketIO). And no, unplugging the network cable doesn't count because I can't really automate that in a unit test :-) Besides, I wish to kill only one specific connection and not all of them. 回答1: It is painful, but it is possible. You can find an explanation here.
