如何访问 google Oauth2 护照中的个人资料信息?

How can I access profile information in google Oauth2 passport?

所以我希望索引页在索引页的页脚中显示当前登录的用户名。
我的google登录路径

router.get("/login/google", passport.authenticate('google', { scope:
    [ 'email', 'profile' ] }));
router.get("/login/google/callback", passport.authenticate("google", {
    successRedirect: "/videos",
    failureRedirect: "/login/google/error"
}));
router.get("/login/google/error", (req, res) => {
    res.send("Error in google login")
})

我的google策略

passport.use(new GoogleStrategy({
    clientID: GOOGLE_CLIENT_ID,
    clientSecret: GOOGLE_CLIENT_SECRET,
    callbackURL: "http://localhost:3000/login/google/callback",
    passReqToCallback: true
  },
  function(request, accessToken, refreshToken, profile, done) {
    User.findOrCreate({ googleId: profile.id }, function (err, user) {
      return done(err, user);
    });
  }
));

我的索引文件的页脚

    <footer>
    <% if(!auth){ %>
      <li class="nav-item">
        <a href="/register" class="nav-link active">Register!</a>
        <li class="nav-item">
          <a href="/login" class="nav-link active">Log In</a>
        </li>
      </li>
    <% } else { %>
      <li class="nav-item">
        <a href="#" class="nav-link disabled">Welcome, <%= auth.username %> </a>
      </li>
      <li class="nav-item">
        <a href="/logout" class="nav-link active">Log Out</a>
      </li>
    <% } %>
  <div class="d-flex justify-content-center mt-3">
  <ul class="nav">
    <li class="nav-item">
      <div class="g-ytsubscribe" data-channelid="UCAjHeCmPJ5lDVWw6dL_jQng" data-layout="default" data-count="default"></div>
    </li>
  </ul>
</footer>

我的页脚

我在我的 google 策略中设置了用户配置文件,然后我知道它是如何保存在 req.user
中的 编辑:
换句话说,我将配置文件变量保存在另一个变量中 (req.user).
