Question

我可以将此代码更改为RxJava编码样式吗？当前的实现如下。我想更改代码以从Async调用获取数据，并将其用于UpdatePublisherImpl.java文件中的其他内容。基本上，从TokenUpdateService.updateBIToken（）获得的任何结果都想用于进一步处理。
无论如何，我可以将此代码更改为RxJava编码样式，并将ABCResponse返回给另一种方法进行进一步处理吗？

//Requires here

function findOrCreate(key, cb) {
    db.collection('users').findOne(key, (err, user) => {
        if (err) {
            console.error(err);
        } else {
            if (!user) {
                db.collection("users").insert(key, cb)
            } else {
                cb(err, user);
            }

            db.close();
        }
    });
}

// config
passport.use(new FacebookStrategy(
    {
        clientID: config.facebook.clientID,
        clientSecret: config.facebook.clientSecret,
        callbackURL: config.facebook.callbackURL
    },
    function(accessToken, refreshToken, profile, done) {
        findOrCreate({
            auth: "facebook",
            id: profile.id
        }, function (err, user) {
            return done(err, user);
        });
    }
));

var app = express();

//View engine setup here

app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({
    extended: false
}));
app.use(cookieParser('sekret'));
app.use(express.static(path.join(__dirname, 'public')));

//Routes here

const cookieExpirationDate = new Date();
const cookieExpirationDays = 365;
cookieExpirationDate.setDate(cookieExpirationDate.getDate() + cookieExpirationDays);

app.use(session({
    secret: 'sekret',
    saveUninitialized: true,
    resave: true
}));
app.use(passport.initialize());
app.use(passport.session());

app.get('/auth/facebook', passport.authenticate('facebook'));
app.get('/auth/facebook/callback',
    passport.authenticate('facebook', {
        successRedirect: '/my-reptiles',
        failureRedirect: '/'
    })
);

app.get('/logout', function(req, res){
    req.logout();
    res.redirect('/');
});

//Error handling here

module.exports = app;
