问题 I've beeen scouring the Net with no luck. I'm trying to figure out how to send a private message from one user to another. There are lots of snippets, but I'm not sure about the client/server interaction. If I have the ID of the socket I want to send to, how do I send it to the server, and how do I ensure the server only sends the message to that one receiver socket? Is there a tutorial or walkthrough that anyone knows of? 回答1: No tutorial needed. The Socket.IO FAQ is pretty straightforward

问题 I can get room's clients list with this code in socket.io 0.9. io.sockets.clients(roomName) How can I do this in socket.io 1.0? 回答1: Consider this rather more complete answer linked in a comment above on the question: https://stackoverflow.com/a/24425207/1449799 The clients in a room can be found at io.nsps[yourNamespace].adapter.rooms[roomName] This is an associative array with keys that are socket ids. In our case, we wanted to know the number of clients in a room, so we did Object.keys(io

问题 So, I have been trying to understand Socket.io lately, but I am not a supergreat programmer, and almost every example I can find on the web (believe me I have looked for hours and hours), has extra stuff that complicates things. A lot of the examples do a bunch of things that confuse me, or connect to some weird database, or use coffeescript or tons of JS libraries that clutter things up. I'd love to see a basic, functioning example where the server just sends a message to the client every 10

问题 I'm trying to setup a Node.js server with socket.io . I'm using the latest template given by WebStorm template. My step is first add socket.io to my language and framework - Node.js and NPM. Here is my setting Then in my "bin/www" I add the below var io = require('socket.io')(server) And add this to bottom of the bin/www file (after server has start listening) io.on("connection",(socket)=>{ console.log("user connected" + socket.id) }) Then I modify my index.jade as below extends layout block

问题 I've a node api(POST)in which the sensor keep on pushing the data to the MongoDB. Now I've an api(GET) which fetches the data from the database and displays on the dashboard.

问题 In the broadcasting messages section http://socket.io/docs/#broadcasting-messages there is the following description To broadcast, simply add a broadcast flag to emit and send method calls. Broadcasting means sending a message to everyone else except for the socket that starts it. Server var io = require('socket.io').listen(80); io.sockets.on('connection', function (socket) { socket.broadcast.emit('user connected'); }); The broadcast is an object. Why does the doc description refers it as

问题 I'm trying to switch from single mysql-queries to mysql-pool connection, so users can share one mysql-connection, but I'm not familiar with this at all (also new to nodejs/socket.io). The following code is what I've done so far to send data every second to the socket in an array: var port = process.env.OPENSHIFT_NODEJS_PORT || 8000, ip = process.env.OPENSHIFT_NODEJS_IP || '127.0.0.1', app = require('http').createServer(handler), fs = require('fs'), request = require('request'), mysql =
