Node.js 带passport的Google Api重定向

我的应用程序中有一个google auth API，我可以用重定向功能附加用户数据吗？或者如何查看用户是否登录了我的react应用程序。 例如，这里我在我的请求字段中发送用户名，但我不知道如何访问它

router.get('/google/redirect', passport.authenticate('google'), (req, res) => {
     res.redirect('http://localhost:3100/login1/' + req.user.username);
});

提前谢谢

您必须像这样请求身份验证流：

router.get('/auth/login',
   (req, res, next) => {

        // Save the url of the user's current page so the app can redirect back to it after authorization
        if (req.query.return) {req.session.oauth2return = req.query.return;}
        next();
    },

    // Start OAuth 2 flow using Passport.js
    passport.authenticate('google', { scope: ['email', 'profile'] })
);

// OAuth 2 callback url.
// Use this url to configure your OAuth client in the Google Developers console.
router.get('/auth/google/callback',

    // Finish OAuth 2 flow using Passport.js
    passport.authenticate('google'), (req, res) => {
        // Redirect back to the original page, if any
        const redirect = req.session.oauth2return || '/';
        delete req.session.oauth2return;
        res.redirect(redirect);
    }
);

然后像这样处理邮件：

router.get('/auth/login',
   (req, res, next) => {

        // Save the url of the user's current page so the app can redirect back to it after authorization
        if (req.query.return) {req.session.oauth2return = req.query.return;}
        next();
    },

    // Start OAuth 2 flow using Passport.js
    passport.authenticate('google', { scope: ['email', 'profile'] })
);

// OAuth 2 callback url.
// Use this url to configure your OAuth client in the Google Developers console.
router.get('/auth/google/callback',

    // Finish OAuth 2 flow using Passport.js
    passport.authenticate('google'), (req, res) => {
        // Redirect back to the original page, if any
        const redirect = req.session.oauth2return || '/';
        delete req.session.oauth2return;
        res.redirect(redirect);
    }
);

虽然您的

localhost

没有任何可路由的IP，但您将永远不会收到任何回传。需要在线托管脚本（使用可公开路由的IP）才能使其“按预期”工作
