node.js - 如何使 passportjs google login oauth 与 JWT 一起工作，而不是通过序列化/反序列化方法创建 session ？

Question

如果我添加创建 session 的序列化/反序列化 passportjs 方法，下面的代码将完美运行。我正在努力创建 Json Web token ，而不是 session 。任何教程、建议或清晰的示例将不胜感激。我使用 nodejs。

我了解 JWT 工作原理的优缺点和基本概述。我是从以下来源了解到的。

app.use(passport.initialize());

app.get("/", function(req, res) {

        function(accessToken, refreshToken, profile, done) {
            process.nextTick(function() {
                console.log("profile.id: " + profile.id);
                return done(null, profile.id); // that is being serealized(added in session)
            });
        }
    )

app.get("/auth/google",
    passport.authenticate(
        "google", {

app.get("/google_callback_success", isLoggedIn, function(req, res) {
    res.send("google_callback_success \n");
});

function isLoggedIn(req, res, next) {
    console.log("isLoggedIn req.user: " + req.user);

    if (req.isAuthenticated()) {
        console.log("isAuthenticated TRUE");
        return next();
    }
    res.redirect("/notloggedin");

app.get("/notloggedin", function(req, res) {
    console.log("req.user: " + req.user);

});

app.get("/google_callback_fail", function(req, res) {
    res.json("the callback after google DID NOT authenticate the user");
});


app.listen(3000);

JWT 代码尝试。问题是我需要添加序列化/反序列化，我不想这样做，因为我不想使用 session 。我要智威汤逊

代码return done(null, profile.id);//正在序列化(添加到 session 中) 是问题所在。我应该用什么来替换它，这样我就不必使用 session 了？我想用 JWT 替换它。

基本上在完成 google 身份验证后，您会为用户创建一个 jwt。

// src/index.js
function generateUserToken(req, res) {
  const accessToken = token.generateAccessToken(req.user.id);
  res.render('authenticated.html', {
    token: accessToken
  });
}

app.get('/api/authentication/google/start',
  passport.authenticate('google', { session: false, scope: 
  ['openid', 'profile', 'email'] }
));
app.get('/api/authentication/google/redirect',
  passport.authenticate('google', { session: false }),
  generateUserToken
);
