问题描述

我已经用socket.io疯了!
文档是如此糟糕,这根本不是真的。



我想通过socket.io向特定客户端发送反馈



我的服务器端如下所示:

  app.get('/ upload',requiresLogin,function请求,响应){
response.render('upload / index.jade');
io.sockets.on('connection',function(socket){
console.log(' SOCKET ID'+ socket.id);
io.sockets.socket(socket.id).emit('new','hello');
});
});

客户端如下所示:

  $(document).ready(function(){
var socket = io.connect('http:// localhost:80 / socket.io / socket.io。 js');
socket.on('new',function(data){
console.log(socket.id);
console.log(data);
/ /$('#state').html(data.status);
});
});

但客户端根本没有任何意义。我几乎尝试了一切。有人可以告诉我我在做错了吗:(

解决方案

向特定客户端发送消息,保存连接到对象中的服务器的每个。

  var socketio = require('socket.io'); 
var clients = {};
var io = socketio.listen(app);

io.sockets.on('connection',function(socket){
clients [socket.id] = socket;
});

然后你可以稍后这样做:

  var socket = clients [sId]; 
socket.emit('show',{});


I´m going crazy with socket.io!Documentation is so bad it's simply not true.

I want to send a feedback to specific client over socket.io

My server side looks like this:

app.get('/upload', requiresLogin, function(request, response) {
    response.render('upload/index.jade');
    io.sockets.on('connection', function (socket) {
        console.log('SOCKET ID ' + socket.id);
        io.sockets.socket(socket.id).emit('new', 'hello');
    });
});

and the client side looks like this:

$(document).ready(function() {
    var socket = io.connect('http://localhost:80/socket.io/socket.io.js');
    socket.on('new', function (data) {
        console.log(socket.id);
        console.log(data);
        //$('#state').html(data.status);
    });
});

but the client does simply nothing. I have tried nearly everything. Can someone tell me what I am doing wrong, please! :(

解决方案

to send a message to a specific client save every one that connects to the server in an Object.

var socketio = require('socket.io');
var clients = {};
var io = socketio.listen(app);

io.sockets.on('connection', function (socket) {
  clients[socket.id] = socket;
});

then you can later do something like this:

var socket = clients[sId];
socket.emit('show', {});
