当对Password.js进行Google身份验证时，从未调用过自定义回调

问题描述：

我尝试使用PassportJS登录到Google.但是当我使用自定义回调时，Google Strategy从未调用过该回调.我究竟做错了什么?我的代码在下面.

I try to login with Google by using PassportJS. But when I use the custom callback, the Google Strategy never called the callback. What am I doing wrong? My codes are below.

端点:

var router = express.Router();
router.get('/',
  passport.authenticate('google', { scope: [
    'https://www.googleapis.com/auth/plus.login',
    'https://www.googleapis.com/auth/plus.profiles.read',
    'https://www.googleapis.com/auth/userinfo.email'
  ] }
));

router.get('/callback', function (req, res) {
  console.log("GOOGLE CALLBACK");
  passport.authenticate('google', function (err, profile, info) {
    console.log("PROFILE: ", profile);
  });
});

module.exports = router;

护照:

passport.use(new GoogleStrategy({
          clientID: config.GOOGLE.CLIENT_ID,
          clientSecret: config.GOOGLE.CLIENT_SECRET,
          callbackURL: config.redirectURL+"/auth/google/callback",
          passReqToCallback: true
          },
          function(request, accessToken, refreshToken, profile, done) {
            process.nextTick(function () {
              return done(null, profile);
            });
          }
        ));

已打印GOOGLE CALLBACK日志，但从未打印过PROFILE日志.

GOOGLE CALLBACK log is printed but PROFILE log never printed.

谢谢.

这是一个棘手的情况...

This is a trick situation...

passport.authenticate方法，返回一个函数.

The passport.authenticate method, returns a function.

如果您以这种方式使用，则必须自己调用它.

And if you use in that way, you have to call it, by yourself.

看:

router.get('/callback', function (req, res) {
  console.log("GOOGLE CALLBACK");
  passport.authenticate('google', function (err, profile, info) {
    console.log("PROFILE: ", profile);
  })(req, res); // you to call the function retuned by passport.authenticate, with is a midleware.
});

或者，您可以这样做:

router.get('/callback', passport.authenticate('google', function (err, profile, info) {
    console.log("PROFILE: ", profile);
  }));

passport.authenticate是中间件.

希望是有帮助的.
