Node.js Authentication with Key cloak server

[Shreyansh jain]

I am using below code for keycloak inside my NodeJS application but once I use keycloak.protect() inside function it is not working. 

app.get('/testPage', testFunction);

function testFunction(req, res) {

    keycloak.protect(), function (req, res) {

        res.render('index', {

            result: JSON.stringify(JSON.parse(req.session['keycloak-token']), null, 4),

            event: '1. Authentication\n2. Login'

        });

    }

}

URL: http://localhost:port/testPage   Not working 

When I used app.get('/loginPage',

    keycloak.protect(), function (req, res) {}); it is working fine. Please let me know what is the issue?

How I can use inside the function this keycloak.protect() method.

URL: http://localhost:port/testPage   working 

app.get('/loginPage',

    keycloak.protect(), function (req, res) {

        res.render('index', {

            result: JSON.stringify(JSON.parse(req.session['keycloak-token']), null, 4),

            event: '1. Authentication\n2. Login'

        });

    }

);
