Node.js oauth20 Bad Token问题

Question

以下是我收到的错误：

TokenError: Bad Request
    at Strategy.OAuth2Strategy.parseErrorResponse (/home/ubuntu/workspace/React/fullstack-basics/node_modules/passport-oauth2/lib/strategy.js:329:12)
    at Strategy.OAuth2Strategy._createOAuthError (/home/ubuntu/workspace/React/fullstack-basics/node_modules/passport-oauth2/lib/strategy.js:376:16)

    at endReadableNT (_stream_readable.js:1054:12)
    at _combinedTickCallback (internal/process/next_tick.js:138:11)

这是我的index.js：

const express = require('express'),
      passport = require('passport'),
      GoogleStrategy = require('passport-google-oauth20').Strategy,
      keys = require('./config/keys');

const app = express();

app.use(express.static('public'));
app.set('view engine', 'ejs');

passport.use(
    new GoogleStrategy(
    {
        clientID: keys.googleClientID,
        clientSecret: keys.googleClientSecret,
        callbackURL: '/auth/google/callback'
    },
        accessToken => {
            console.log(accessToken);
        }
    )
);

app.get('/', (req, res) => {
   res.render('index'); 
});


app.get('/auth/google', 
    passport.authenticate('google', {
        scope: ['profile', 'email']
    })
);

app.get('/auth/google/callback', passport.authenticate('google'));


const PORT = process.env.PORT || 8080;

app.listen(PORT, process.env.IP, () => {
    console.log('Server is listening..');  
});

我正在使用C9 我在API应用设置中的设置如下：

授权的JavaScript来源 - ＆gt; http://learning-space-fvrthebrave.c9users.io 授权重定向URI - ＆gt; http://learning-space-fvrthebrave.c9users.io/auth/google/callback

我被困在这里，无法判断我的代码是否存在问题或oauth存在问题！
