I have an express node.js server serving Socket.io. I would like the ability to make get requests to the express server that will automatically send a message to a channel.
var app = require('express').createServer()
, io = require('socket.io').listen(app)
app.listen(80);
app.get('/:channel/:message', function (req, res) {
//Code to create socket
socket.emit("sent from get", {channel:req.params.channel, message:req.params.message})
});
io.sockets.on('connection', function (socket) {
socket.on('sent from get', function (data) {
socket.broadcast.to(data.channel).emit('channel message', { message: data.message});
});
});
How to I create (and destroy) a socket connection in the app.get
block?
(For clarity, I want to use this to send a quick message from a rails server when a particular object is saved, and have a message pushed to each appropriate user.)
io.sockets.in(req.params.channel).emit("channel message", {mes:req.params.message})
这将向请求频道中的所有用户发送一条消息。
var chat = io.of('/chat').on('connection', function (socket) {
socket.emit('a message', { that: 'only', '/chat': 'will get' });
chat.emit('a message', { everyone: 'in', '/chat': 'will get' }); });
The following example defines a socket that listens on '/chat'
