如何为socket.io握手（sails.js）发送cookie？

Question

我正在尝试使用以下代码（从this gist中提取）：

var io = require('socket.io-client');
var request = require('request');
var xhr = require('socket.io-client/node_modules/xmlhttprequest');
var xhrOriginal = require('xmlhttprequest');

var myUrl = 'http://192.168.56.101:1337';
var cookieJar = request.jar();

// From socket.io-client's module 'xmlhttprequest', rewrie its XMLHttpRequest function.
xhr.XMLHttpRequest = function() {
    this.XMLHttpRequest = xhrOriginal.XMLHttpRequest;
    xhrOriginal.XMLHttpRequest.apply(this, arguments);
    this.setDisableHeaderCheck(true); // Allow header modifications.

    // Rewrite the 'open' function.
    var openOriginal = this.open;
    this.open = function(method, url, async, user, password) {
        openOriginal.apply(this, arguments);
        var header = cookieJar.get({url: myUrl}).map(function(cookie) {
            return cookie.name + '=' + cookie.value;
        }).join('; ');
        this.setRequestHeader('cookie', header);
    };
};

// Send the cookie first before attempting to connect via socket-io,
// thus, avoiding the handshake error.
request.post({jar: cookieJar, url: myUrl}, function(err, resp, body) {
    var socket = io.connect(myUrl);
    socket.on('connecting', function() {
        console.log('(II) Connecting to server');
    });
    socket.on('connect', function() {
        console.log('(II) Successfully connected to server');
    });
    socket.on('error', function(reason) {
        console.log('(EE) Error connecting to server: ' + reason);
    });
    socket.on('disconnect', function(reason) {
        console.log('(II) Disconnected from server\n');
    });
});

使用socket.io/sails.js实现更简单的握手过程，但我无法使其工作。

有人可以解释如何正确使用它吗？是否打算以某种方式在客户端中以导入的脚本运行？或作为服务页面？

提前致谢。
