令牌错误：错误请求；谷歌 OAuth2；Node.js 上的 Passport.js；能够使用 console.log 数据，但是会出现错误

Question

我试图使用Passport.js授权谷歌OAuth2上Node.js。我整个星期都在尝试让它工作，但不知道为什么它不工作，所以我现在求助于堆栈以获得一些潜在的帮助。我已经尝试了在线论坛上提供的类似问题的所有解决方案。

每次发送请求时，它都会返回 TokenError: Bad Request，但是，它能够通过 console.log 记录所需的数据，所以这对我来说表明令牌实际上是成功的。我无法解释为什么会发生这种情况。

我尝试在回调请求中更具体，例如http://localhost:3000/auth/google/redirect。我已经尝试了所有其他类型的 Oauth 类型谷歌有节点服务器、Web 应用程序、html 等。我尝试了不同的端口。

授权路线

 const router = require('express').Router();
 const passport = require('passport');

 // auth login
 router.get('/login', (req, res) => {
     res.render('login', { user: req.user });
 });

 // auth logout
 router.get('/logout', (req, res) => {
     // handle with passport
     res.send('logging out');
 });

 // auth with google+
 router.get('/google', passport.authenticate('google', {
     scope: ['profile']
 }));

 // callback route for google to redirect to
 // hand control to passport to use code to grab profile info
     router.get('/google/redirect', passport.authenticate('google'), 
   (req, 
   res) => {
      res.send('you reached the redirect URI');
   });

module.exports = router;

PASSPORT_SETUP

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

passport.use(
new GoogleStrategy({
    // options for google strategy
    clientID: keys.google.clientID,
    clientSecret: keys.google.clientSecret,
    callbackURL: '/auth/google/redirect'
   }, (accessToken, refreshToken, profile, done) => {
    // passport callback function
    console.log('passport callback function fired:');
    console.log(profile);
    })
);

当提交过程通过登录页面进行时，将期望的结果传递到 console.log，然后等待 localhost 大约 1 分钟。

正如你所看到的，它试图检索的东西已经在控制台中了。

然后它继续抛出和错误：

抱歉回复晚了，挖出了一些旧代码，这就是它被标记为“所有身份验证方法都起作用”的地方。正如 Aritra Chakraborty 在评论中所述，“完成”方法没有被调用。请参阅以下使用 Nedb 的实现。

const GoogleStrategy = require('passport-google-oauth20').Strategy;
const Datastore = require('nedb');
const database = new Datastore('database.db');
database.loadDatabase();

passport.serializeUser((user, done) => {
    done(null, user.googleId || user.id);
});

passport.deserializeUser((googleId, done) => {
    database.findOne({ googleId : googleId }, (err, user) => {
        done(null, user);
    });
});

var strategy = new GoogleStrategy({
    // options for google strategy
    clientID: keys.google.clientID,
    clientSecret: keys.google.clientSecret,
    callbackURL: '/auth/google/redirect'
}, (accessToken, refreshToken, object0, profile, done) => {
    // check if user already exists in our own db
    database.findOne({ googleId: profile.id }, (err, currentUser) => {
        if (currentUser !== null) {
            done(null, currentUser);
        } else {
            var d = new Date();
            var n = d.getTime();
            var duoID = uuidv1();
            var User = {
                duoVocalID: duoID,
                googleId: profile.id,
                username: profile.displayName,
                thumbnail: profile._json.image.url,
                oscope: object0.scope,
                oaccess_token: object0.access_token,
                otoken_type: object0.token_type,
                oid_token: object0.id_token,
                oexpires_in: object0.expires_in,
                oemails: profile.emails,
                olanguage: profile._json.language,
                oname: profile.name,
                TimeOfLastLogon: n,
                RefreshToken: refreshToken
            };
          
            database.insert(User, (err, newUser) => { });
            var newUser = User;
            done(null, newUser);
        }
    });
});

passport.use(strategy);

// auth with google+
app.get('/auth/google', passport.authenticate('google', {
    scope: ['profile', 'email', 'https://www.googleapis.com/auth/spreadsheets'],
    accessType: 'offline', 
    approvalPrompt: 'force' 
}));

// callback route for google to redirect to
// hand control to passport to use code to grab profile info
app.get('/auth/google/redirect', passport.authenticate('google'), async (req, res) => {
    var userString = JSON.stringify(req.user)
    jwt.sign({userString}, 'secretKey', { expiresIn: '365d' }, (err, token) => {
        res.send("<script>localStorage.setItem('token', '"+token+"'); window.close(); window.opener.document.getElementById('modal-toggle').checked = false;</script>");
    });
});
