【问题描述】：
我已经能够使用 node.js 和 passport.js 通过 GitHub 项目连接到 Facebook：https://github.com/jaredhanson/passport-facebook/tree/master/examples/login。
下面是 app.js 代码的作用：
var express = require('express')
, passport = require('passport')
, util = require('util')
, FacebookStrategy = require('passport-facebook').Strategy
, logger = require('morgan')
, session = require('express-session')
, bodyParser = require("body-parser")
, cookieParser = require("cookie-parser")
, methodOverride = require('method-override');
var FACEBOOK_APP_ID = "--insert-facebook-app-id-here--"
var FACEBOOK_APP_SECRET = "--insert-facebook-app-secret-here--";
// Passport session setup.
// To support persistent login sessions, Passport needs to be able to
// serialize users into and deserialize users out of the session. Typically,
// this will be as simple as storing the user ID when serializing, and finding
// the user by ID when deserializing. However, since this example does not
// have a database of user records, the complete Facebook profile is serialized
// and deserialized.
passport.serializeUser(function(user, done) {
done(null, user);
});
passport.deserializeUser(function(obj, done) {
done(null, obj);
});
// Use the FacebookStrategy within Passport.
// Strategies in Passport require a `verify` function, which accept
// credentials (in this case, an accessToken, refreshToken, and Facebook
// profile), and invoke a callback with a user object.
passport.use(new FacebookStrategy({
clientID: FACEBOOK_APP_ID,
clientSecret: FACEBOOK_APP_SECRET,
callbackURL: "http://localhost:3000/auth/facebook/callback"
},
function(accessToken, refreshToken, profile, done) {
// asynchronous verification, for effect...
process.nextTick(function () {
// To keep the example simple, the user's Facebook profile is returned to
// represent the logged-in user. In a typical application, you would want
// to associate the Facebook account with a user record in your database,
// and return that user instead.
return done(null, profile);
});
}
));
var app = express();
// configure Express
app.set('views', __dirname + '/views');
app.set('view engine', 'ejs');
app.use(logger());
app.use(cookieParser());
app.use(bodyParser());
app.use(methodOverride());
app.use(session({ secret: 'keyboard cat' }));
// Initialize Passport! Also use passport.session() middleware, to support
// persistent login sessions (recommended).
app.use(passport.initialize());
app.use(passport.session());
app.use(express.static(__dirname + '/public'));
app.get('/', function(req, res){
res.render('index', { user: req.user });
});
app.get('/account', ensureAuthenticated, function(req, res){
res.render('account', { user: req.user });
});
app.get('/login', function(req, res){
res.render('login', { user: req.user });
});
// GET /auth/facebook
// Use passport.authenticate() as route middleware to authenticate the
// request. The first step in Facebook authentication will involve
// redirecting the user to facebook.com. After authorization, Facebook will
// redirect the user back to this application at /auth/facebook/callback
app.get('/auth/facebook',
passport.authenticate('facebook'),
function(req, res){
// The request will be redirected to Facebook for authentication, so this
// function will not be called.
});
// GET /auth/facebook/callback
// Use passport.authenticate() as route middleware to authenticate the
// request. If authentication fails, the user will be redirected back to the
// login page. Otherwise, the primary route function function will be called,
// which, in this example, will redirect the user to the home page.
app.get('/auth/facebook/callback',
passport.authenticate('facebook', { failureRedirect: '/login' }),
function(req, res) {
res.redirect('/');
});
app.get('/logout', function(req, res){
req.logout();
res.redirect('/');
});
app.listen(3000);
// Simple route middleware to ensure user is authenticated.
// Use this route middleware on any resource that needs to be protected. If
// the request is authenticated (typically via a persistent login session),
// the request will proceed. Otherwise, the user will be redirected to the
// login page.
function ensureAuthenticated(req, res, next) {
if (req.isAuthenticated()) { return next(); }
res.redirect('/login')
}
如果我只是在没有代理服务器的情况下使用互联网，则代码效果很好，但如果我在公司防火墙后面，则会收到以下错误：
InternalOAuthError: Failed to obtain access token

有谁知道如何设置上面的代码以通过公司代理服务器进行连接？我曾尝试设置代理、http-proxy 和 https-proxy 的 npm 配置属性，但在我运行此应用程序时似乎没有什么不同。您能提供的任何帮助将不胜感激。谢谢。
