Node.js/passport-Facebook authentication

问题

I am trying to implement a simple Facebook login integration using passport (passport-facebook) authentication middleware. Regarding to this documentation over here I have some code here from my server.js:

var express = require('express'),
    passport = require('passport'),
    FacebookStrategy = require('passport-facebook').Strategy,
    app = express();

// Facebook authentication:
passport.use(
    new FacebookStrategy({
        clientID: "fb client id here",
        clientSecret: "fb client secret key here",
        callbackURL: "http://localhost/web-apps/facebook-passport/auth/facebook/"
    },
    function(accessToken, refreshToken, profile, done) {
        console.log("auth is done!");
        done(null, profile);
    })
);

app.get('/web-apps/facebook-passport/auth/facebook', passport.authenticate('facebook'));

app.get(
    '/web-apps/facebook-passport/auth/facebook/',
    passport.authenticate('facebook', {
        successRedirect: '/',
        failureRedirect: '/login'
    })
);

app.get('/web-apps/facebook-passport/', function(req, res) {
    res.send('<a href="/web-apps/facebook-passport/auth/facebook">Login with Facebook</a>');
});

app.listen(80);

The code basically provides a link that should lead to Facebook authentication (/facebook/auth), ask the client for permission and then redirect user back to my page with some access tokens and client's details. However, when I run my server and try to do that by pressing the link I got

passport.initialize() middleware not in use

Passport stacktrace:

I guess I would need to add something like app.configuration to my server-side script but these are gone in express 4.x version. I am wondering how I could fix this?

My node packages are:

-passport@0.2.1

-passport-facebook@1.03

-express@4.11.1

**** U P D A T E ****

I've added the following code to the top of my script which was result loosing the previous error message:

app.use(bodyParser());

// Use the passport package in our application
app.use(passport.initialize());

// Create our Express router
var router = express.Router();

However, I got this new error saying

This authorization code has been used.

This is the stack trace:

FacebookTokenError: This authorization code has been used.

Solved:

Problems with URIs.

回答1:

Try using this way in your

app.get('/web-apps/facebook-passport/auth/facebook', passport.authenticate('facebook-signup', { session: false }));

instead of

app.get('/web-apps/facebook-passport/auth/facebook', passport.authenticate('facebook'));

I think the problem is that facebook logged you an returned a token, if you dont close the session, facebook is waiting for the same token. Using {session: false} cause facebook close session after the authentication is done. You will be receiving a new token each time you authenticate.

I have had some problems like this before, i m not an expert, but also i solved it in this way.
