護照Facebook的策略在NextJS應用程序返回undefined值

Question

我使用的護照Facebook的插件和我的測試腳本定義的策略如下：

// Configure Passport 
// --------------------------------------------------------------- 
passport.use(new LocalStrategy(User.authenticate())); 
passport.use(new FacebookStrategy({ 
    clientID: process.env.FACEBOOK_APP_ID, 
    clientSecret: process.env.FACEBOOK_APP_SECRET, 
    callbackURL: process.env.FACEBOOK_APP_CALLBACK, 
}, 
    function (accessToken, refreshToken, profile, done) { 
    console.log(profile); 
    } 
)); 
passport.serializeUser(User.serializeUser()); 
passport.deserializeUser(User.deserializeUser()); 
// --------------------------------------------------------------- 

我的認證途徑是：

// Facebook 
router.get('/auth/facebook', passport.authenticate('facebook')); 
router.get('/facebook/callback', 
    passport.authenticate('facebook', { 
    successRedirect: '/success', 
    failureRedirect: '/failure', 
    }), 
); 

我現在所要做的就是顯示Facebook成功驗證後返回的所有值。認證工作正常但Facebook似乎在profile對象被返回undefined大多數鍵：

{ id: '1234567812345677', 
    username: undefined, 
    displayName: 'John Doe', 
    name: 
    { familyName: undefined, 
    givenName: undefined, 
    middleName: undefined }, 
    gender: undefined, 
    profileUrl: undefined, 
    provider: 'facebook', 
    _raw: '{"name":"John Doe","id":"1234567812345677"}', 
    _json: { name: 'John Doe', id: '1234567812345677' } } 

我得到的是displayName和id;其他一切都是undefined。出了什麼問題？之前在這裏提出了一個非常類似的問題，但沒有一個答案（沒有被接受的答案）提供瞭解決問題的方法。

我沒有這方面的經驗，但從看facebook-passport的readme，聽起來好像你需要在你的FacebookStrategy中使用profileFields。 ：

The Facebook profile contains a lot of information about a user. By default, not all the fields in a profile are returned. The fields needed by an application can be indicated by setting the profileFields option.

new FacebookStrategy({ 
    clientID: FACEBOOK_APP_ID, 
    clientSecret: FACEBOOK_APP_SECRET, 
    callbackURL: "http://localhost:3000/auth/facebook/callback", 
    profileFields: ['id', 'displayName', 'photos', 'email'] 
}), ...) 

Refer to the User section of the Graph API Reference for the complete set of available fields.
