我的代码如下(用于Google登录的代码段):-

My code is as follows(snippet for google login):-

passport.use(new GoogleStrategy(google, function(req, accessToken, refreshToken, profile, done) {
  if (req.user) {
    User.findOne({ google: profile.id }, function(err, existingUser) {
      if (existingUser) {
        console.log('There is already a Google+ account that belongs to you. Sign in with that account or delete it, then link it with your current account.' );
        done(err);
      } else {
        User.findById(req.user.id, function(err, user) {
          user.google = profile.id;
          user.tokens.push({ kind: 'google', accessToken: accessToken });
          user.profile.displayName = user.profile.displayName || profile.displayName;
          user.profile.gender = user.profile.gender || profile._json.gender;
            //user.profile.picture = user.profile.picture || 'https://graph.facebook.com/' + profile.id + '/picture?type=large';
          user.save(function(err) {
            console.log('Google account has been linked.');
            done(err, user);
          });
        });
      }
    });
  } else {
    User.findOne({ google: profile.id }, function(err, existingUser) {
      if (existingUser) return done(null, existingUser);
      User.findOne({ email: profile._json.email }, function(err, existingEmailUser) {
        if (existingEmailUser) {
           console.log('There is already an account using this email address. Sign in to that account and link it with Google manually from Account Settings.' );
          done(err);
        } else {
          var user = new User();
          user.email = profile._json.email;
          user.google = profile.id;
          user.tokens.push({ kind: 'google', accessToken: accessToken });
          user.profile.displayName = profile.displayName;
          user.profile.gender = profile._json.gender;
            //user.profile.picture = 'https://graph.facebook.com/' + profile.id + '/picture?type=large';
          user.profile.location = (profile._json.location) ? profile._json.location.name : '';
          user.save(function(err) {
            done(err, user);
          });
        }
      });
    });
  }
}));

我坚持下去.请帮帮我..谢谢

推荐答案

问题不在您的代码段"中，请查看路由.对于Google重定向，它应该是绝对路径.

The problem is not in your "snippet", look at the routes. It should be absolute path on redirect for google.

router.get('/auth/google/callback',
passport.authenticate('google', { failureRedirect: '#/signIn' }),
function(req, res) {
// absolute path
    res.redirect('http://localhost:8888/#/home');
});
