【问题描述】：

尝试使用 LinkedIn 的 oAuth 2.0 对新用户进行身份验证时出现上述错误。看起来我正在传递一个 10 位的 ObjectId 而不是 12 或 24 个字符的 id...

passport.use(new LinkedInStrategy({
  clientID: process.env.LI_ID,
  clientSecret: process.env.LI_SECRET,
  callbackURL: "http://localhost:3000/auth/linkedin/think-it",
  scope: ['r_emailaddress', 'r_liteprofile'],
  state: true
}, function(accessToken, refreshToken, profile, done) {
  // asynchronous verification, for effect...
  process.nextTick(function () {
    // To keep the example simple, the user's LinkedIn profile is returned to
    // represent the logged-in user. In a typical application, you would want
    // to associate the LinkedIn account with a user record in your database,
    // and return that user instead.
    return done(null, profile);
  });
}));

我要挂断电话了：

passport.deserializeUser(function(id, done) {
  User.findById(id, function(err, user) {
    done(err, user);
  });
});

【解决方案1】：

已解决。我没有从我的数据库返回用户。从上面的代码：

...function(accessToken, refreshToken, profile, done) {
  // asynchronous verification, for effect...
  process.nextTick(function () {
    //code below was not present when I was getting the error:
    User.findOrCreate({ linkedInId: profile.id}, function(err, user) {
          if (err) { return done(err); }
          done(null, user);
        });
  });
