Socket.IO

问题 I have just started using node.js, I'm running a node server with sockets.io and i need to send a buffer of bytes to the client. I understand that this can be done by first translating the byte buffer to base64 and sending that, then translating it back on the client side. but i was wondering if there is a more elegant way of getting the byte stream to the client. 回答1: Socket.IO 1.0 Now supports Binary data transfer. Please have a look here . You can use Blob, ArrayBuffer and File. 回答2: https

问题 I'm going to create voice chat. My backend server works on Node.js and almost every connection between client and server uses socket.io. Is websockets appropriate for my use case? I prefer communication client -> server -> clients than P2P because I expect even 1000 clients connected to one room. If websocket is ok, then which method is the best to send AudioBuffer to server and playback on other clients? I do it like that: navigator.getUserMedia({audio: true}, initializeRecorder,

问题 io on server and client on android. It results in connection error on android as long as I enable HTTP(S) SSL(works fine if disable it however) I've tried to implement HTTPS connection on Android, took reference from sample on Github as following: opts = new IO.Options(); opts.sslContext = mySSLContext; opts.hostnameVerifier = myHostnameVerifier; socket = IO.socket("https://mychat.url", opts); also this SSLContext mySSLContext = SSLContext.getInstance("TLS"); mySSLContext.init(null, null,

问题 I am building an app using socket.io I'm using socket.io's rooms feature, there are 5 "topics" a user can subscribe to. Each message broadcast in that topic has a message type, of which there are 100. A user will only receive the messages of the types they are allowed to receive, which could be between 30 and 70. My question: is it feasible to create a room for every topic + message type combination, which will be 5 x 100 rooms? Will socket.io perform well like this, or is there a better way

问题 I am fairly new to all of these technologies (including somewhat JavaScript) so you might have to bear with me here. I followed the ChatApp tutorial over at Socket.IO docs fairly closely and modified the application to my likings somewhat; however, I don't think I changed much on the side of server interaction and stuff. My problem is no matter what I do, I can't seem to be able to get my application to successfully run on Heroku. I get this error message when trying to load the app:

问题 I am trying to add some custom information to my socket object on connect, so that when I disconnect the socket, I can read that custom information. IE: // (Client) socket.on('connect', function(data){ socket.customInfo = 'customdata'; }); // (server) socket.on('disconnect', function () { console.log(socket.customInfo); }); 回答1: Since it is JavaScript you can freely add attributes to any object (just as you did). However socket.io does give you a built-in way to do that (so you won't have to

问题 I am writing a simple socket.io(v1.3.6)-based chatting program. When users log in with their username, they could see several chatting rooms in dashboard and enter each of them via different end ponts, i.e, http://localhost:8080/api/chats/room01 . Users could chat in any one of these rooms. For each room, I would like to create an active user list. 'active' means this user is now connected to socket (chatting in this room). I see many questions have been posted but still confused by their few
