用于socket.io服务器的Node.js客户端

Question

我有一个socket.io服务器运行和一个与socket.io.js客户端匹配的网页.一切正常.

但是,我想知道是否有可能在另一台机器上运行一个单独的node.js应用程序,它将充当客户端并连接到提到的socket.io服务器？

Answer 1

这应该可以使用Socket.IO-client:https://github.com/LearnBoost/socket.io-client

Answer 2

为前面给出的解决方案添加示例.使用socket.io-client https://github.com/socketio/socket.io-client

客户端:

//client.js
var io = require('socket.io-client');
var socket = io.connect('http://localhost:3000', {reconnect: true});

// Add a connect listener
socket.on('connect', function (socket) {
    console.log('Connected!');
});
socket.emit('CH01', 'me', 'test msg');

服务器端 :

//server.js
var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);

io.on('connection', function (socket){
   console.log('connection');

  socket.on('CH01', function (from, msg) {
    console.log('MSG', from, ' saying ', msg);
  });

});

http.listen(3000, function () {
  console.log('listening on *:3000');
});

跑 :

打开2控制台并运行node server.js和node client.js

Answer 3

安装socket.io-client后:

npm install socket.io-client

这是客户端代码的样子:

var io = require('socket.io-client'),
socket = io.connect('localhost', {
    port: 1337
});
socket.on('connect', function () { console.log("socket connected"); });
socket.emit('private message', { user: 'me', msg: 'whazzzup?' });
