我是developign api（javascript），passport-google-oauth2我碰到了砖墙。

我找到了许多“基本指南”并遵循了它们...

添加策略： onst myconst= require('../myconst'); const GoogleStrategy = require('passport-google-oauth2').Strategy;

const config = {
    clientID: myconst.AUTHORIZATION_GOOGLE_CLIENT_ID,
    clientSecret: myconst.AUTHORIZATION_GOOGLE_CLIENT_SECRET,
    callbackURL: myconst.AUTHORIZATION_GOOGLE_CALLBACK,
    passReqToCallback: true
}
module.exports = () => {
    return new GoogleStrategy(
        config,
        (request, accessToken, refreshToken, profile, done) => {
            console.log(`-> I got a. token : ${accessToken}`); // just so I can see it
            process.nextTick( () => {
                return done(null, profile);
            });
        }
    );

然后，我将其包含在护照中：

// 护照.js

const passport = require('passport');
const strategyOfGoogle = require('./strategies/strategyOfGoogle');

passport.use(strategyOfGoogle());

passport.serializeUser(function (user, done) {
    console.log(' -> Serializing user');
    done(null, user);
});

passport.deserializeUser(function (user, done) {
    console.log(' -> Deserializing user');
    done(null, user);
});

exports.registerPassport = (app) => {
    app.use(passport.initialize());
    app.use(passport.session());
};

在我的主文件 - app.js 中我添加了：

const session = require('express-session');
const authenticationPassport = require('./authentication/passport.js');
const passport = require('passport');

// some basic initialziation as http server, db, etc. skipped to make this code a bit shorter

authenticationPassport.registerPassport(app);

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

var ensureAuthenticated = (req, res, next) => {
    if (req.isAuthenticated()) {
        return next();
    }
    res.redirect('/auth/google');
};


routes.forEach((route) => {
    const code = require(route.path); 
    const router = code(routeConfig);
    app.use(route.uri,
        // #1
        //ensureAuthenticated,
        // #2
        /*(req, res, next) => {
            console.log(` >> Request : ${req.originalUrl}`);
            return next();
        },*/
        // #3
        passport.authenticate('google', {scope: ['profile', 'email']}),
        router);
});

app.get('/auth/google',
    function (req, res, next) {
        next();
    },
    passport.authenticate('google', { scope: ['profile', 'email'] })
);

app.get('/auth/google/callback',
    passport.authenticate('google', {
        failureRedirect: `/api/v${process.env.MY_VERSION}`
    }),
    function (req, res) {
        // Authenticated successfully
        console.log(`Authenticated it! ${req.isAuthenticated()}`); //alwasy gets tru here
        res.redirect(`/api/v${process.env.MY_VERSION}/api-docs/#/`);
    }
);

在所有这一切之后 - 在路由中尝试了 #1 - #3 变种，但它总是将我与每个请求重定向到/auth/google/callback. 我用简单的“GET”（本地主机：8000/api/v1.1/objects1）尝试了它并且只重定向了 - 即使我用谷歌登录，下一个请求我将再次被重定向到相同的路由以进行自动复制。我真的很困惑，真的不知道如何解决它了。你能指出我，这里有什么问题吗？我哪里做错了？
