护照Facebook的策略在NextJS应用程序返回undefined值

Question

我使用的护照Facebook的插件和我的测试脚本定义的策略如下：

// 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()); 
// --------------------------------------------------------------- 

我的认证途径是：

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

我现在所要做的就是显示Facebook成功验证后返回的所有值。认证工作正常但Facebook似乎在profile对象被返回undefined大多数键：

{ 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。出了什么问题？之前在这里提出了一个非常类似的问题，但没有一个答案（没有被接受的答案）提供了解决问题的方法。

我没有这方面的经验，但从看facebook-passport的readme，听起来好像你需要在你的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.
