使用 Passport 进行社交身份验证登录后如何重定向到个人资料页面？ （角度，快递，护照，jwt）

Question

I'm using passport to achieve login with FB or Google on my app.

I succeed to create a profile if it doesn't exist but now I don't understand how to send those information to the front when I want to login. I tried many thing like use res.cookie(blabla) , but couldn't use it in front. res.send(blabla) just open a json file.

I certainly missed something but I don't know what.

Here is my passportjs file:

import passport from 'passport';
import { UsersService } from './../services/users.service';
import { AuthService } from './../services/auth.service';
import * as jwt from 'jsonwebtoken';

let FacebookStrategy = require('passport-facebook').Strategy;
const usersService = UsersService.getInstance();

module.exports = function () {
    passport.use('facebook', new FacebookStrategy({
        clientID : CLIENTID,
        clientSecret    : CLIENTSECRET,
        callbackURL     : 'http://localhost:3000/auth/facebook/callback',
        profileFields: ['id', 'emails', 'name']
    },
    function(access_token:any, refresh_token:any, profile:any, done:any) {
        process.nextTick(function() {
            usersService.getByEmail(profile.emails[0].value).then((result) => {
                if(result.email == profile.emails[0].value) {
                    console.log('EXISTE');
                    const userToken = {
                        email: result.email,
                        id: result.id
                    };
                    const secret: any = process.env.JWT_SECRET;
                    const token = jwt.sign(userToken, secret);
                    let newUser : any = result;
                    newUser.jwtoken = token;
                    console.log(newUser)
                    return done(null, newUser)
                } else{
                    console.log('EXISTE PAS')
                    let user: any = {
                        email : profile.emails[0].value,
                        username : profile.username
                    }
                    usersService.create(user).then(result => {
                        return done(null, user)
                    })
                } 
            })

        });
        }
    ))
}

Here is my route file:

router.get('/facebook', passport.authenticate('facebook', { scope: 'email'  }))


    router.get('/facebook/callback', 
        passport.authenticate('facebook', {
            session: false,
            failureRedirect : 'http://localhost:4200/auth/signin'
        }), (req: any, res: Response) => {
            let token: any = req.user.jwtoken;
            res.send(token).redirect('http://localhost:4200/')
        }
    );

Answer 1

So I tried an other thing for the redirection:

router.get('/facebook', passport.authenticate('facebook', { scope: 'email'  }))
    router.get('/facebook/callback', 
        passport.authenticate('facebook', {
            session: false,
            failureRedirect : 'http://localhost:4200/auth/signin'
        }), (req: any, res: Response) => {
            let user: any = req.user;
            res.redirect('http://localhost:3000/users/me', user);
        }
    );

And now I have an error:

FacebookTokenError: This authorization code has been used.

    at process._tickCallback (internal/process/next_tick.js:63:19)

I don't really understand why I got this error since nobody is logged on my website.
