使用socket.io和空消息队列发送消息到特定客户端 [英] Sending message to specific client with socket.io and empty message queue

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', {});
