会话（节点，快递，会话，护照）中的req.user不明

Question

For some reason req.user is undefined, and after 4+ hours of trying to figure out why, I'm asking here. I even copy-pasted the server/index.js file of a friend's server, changed the auth strategy so it worked for mine, and I get the same issue.

Everything else is working. It redirects to auth0, comes back to the correct place, either creates a new user in the DB or finds the user. In passport.serializeUser it has all the data I passed along. But when I hit the '/auth/me' endpoint, req.user is undefined.

server/index.js

 require('dotenv').config(); const express = require('express'); const bodyParser = require('body-parser'); const cors = require('cors') const session = require("express-session"); const passport = require('passport'); const Auth0Strategy = require('passport-auth0'); const massive = require('massive'); const axios = require('axios'); const process = require("process"); const moment = require('moment'); const app = express(); //app.use(express.static(__dirname + './../build')); app.use(bodyParser.json()); app.use(cors()); app.use(session({ secret: process.env.SECRET, cookie: { maxAge: 60000 }, resave: false, saveUninitialized: true })); app.use(passport.initialize()); app.use(passport.session()); // Use the session middleware massive(process.env.CONNECTION_STRING) .then( (db) => { console.log('Connected to Heroku') app.set('db', db); }).catch(err=>console.log(err)) passport.use(new Auth0Strategy({ domain: process.env.AUTH_DOMAIN, clientID: process.env.AUTH_CLIENT_ID, clientSecret: process.env.AUTH_CLIENT_SECRET, callbackURL: process.env.AUTH_CALLBACK }, (accessToken, refreshToken, extraParams, profile, done) => { const db = app.get("db"); const userData = profile._json; db.find_user([userData.identities[0].user_id]).then(user => { if (user[0]) { return done(null, user[0]); } else { db.create_user([ userData.given_name, userData.family_name, userData.email, userData.identities[0].user_id ]) .then(user => { return done(null, user); }); } }); })) passport.serializeUser( (user, done) => { //console.log('serializeuser', user) done(null, user); }) passport.deserializeUser( (id, done) => { app.get("db").find_session_user([id]) .then(user => { console.log(user); done(null, user[0]); }); }) app.get('/auth', passport.authenticate('auth0')); app.get('/auth/callback', passport.authenticate('auth0', { successRedirect: process.env.SUCCESS_REDIRECT })) app.get('/auth/me', (req, res) => { console.log('auth/me endpoint hit') console.log(req.user) if(!req.user){ return res.status(401).send('No user logged in.'); } return res.status(200).send(req.user); }) app.listen(process.env.PORT, () => console.log(`Listening on port: ${process.env.PORT}`)); 

server/.env

 CONNECTION_STRING=postgres:***** SECRET=******* AUTH_DOMAIN=****.auth0.com AUTH_CLIENT_ID=*** AUTH_CLIENT_SECRET=*** AUTH_CALLBACK=http://localhost:8084/auth/callback SUCCESS_REDIRECT=http://localhost:3000/ PORT=8084 

Answer 1

Try moving the app.get('/auth', passport.authenticate('auth0')); line after the app.get('/auth/me', (req, res) => { block. app.get can do regex matches and goes with the first one that matches ( http://expressjs.com/en/api.html#path-examples ), and I think it's trying to run the /auth logic for the /auth/me path.
