这是我输入的代码。

var passport = require("passport");
var GoogleStrategy = require("passport-google-oauth").OAuth2Strategy;

// Use the GoogleStrategy within Passport.
//   Strategies in Passport require a `verify` function, which accept
//   credentials (in this case, an accessToken, refreshToken, and Google
//   profile), and invoke a callback with a user object.
passport.use(
  new GoogleStrategy(
    {
      clientID: '28013134812-qc5lbogacg4cf42etiruqveskh8vaqgh.apps.googleusercontent.com',
      clientSecret: 'secret! i can't type secret here',
      callbackURL: "www.example.com.com/auth/google/callback",
    },
    function (accessToken, refreshToken, profile, done) {
      User.findOrCreate({ googleId: profile.id }, function (err, user) {
        return done(err, user);
      });
    }
  )
);

// GET /auth/google
//   Use passport.authenticate() as route middleware to authenticate the
//   request.  The first step in Google authentication will involve
//   redirecting the user to google.com.  After authorization, Google
//   will redirect the user back to this application at /auth/google/callback
app.get(
  "/auth/google",
  passport.authenticate("google", {
    scope: ["https://www.googleapis.com/auth/plus.login"],
  })
);

// GET /auth/google/callback
//   Use passport.authenticate() as route middleware to authenticate the
//   request.  If authentication fails, the user will be redirected back to the
//   login page.  Otherwise, the primary route function function will be called,
//   which, in this example, will redirect the user to the home page.
app.get(
  "/auth/google/callback",
  passport.authenticate("google", { failureRedirect: "/login" },
  function (req, res) {
    res.redirect("/");
  })
);

我从护照文档中复制了上述代码。有谁知道我为什么会收到这个错误？ 这里的用户实际上是什么？

我认为这段代码有问题

function (accessToken, refreshToken, profile, done) {
      User.findOrCreate({ googleId: profile.id }, function (err, user) {
        return done(err, user);
      });
    }

只需在此处输入正确的回调 URL callbackURL: "http://localhost:3000.com/auth/google/callback",并定义用户。就是这样
