Javascript SDK state for oAuth 2

You have to create an AuthorizeRequest object and call the rc.authorizeUri() method.

See the sample code on this quick start

https://developers.ringcentral.com/guide/authentication/quick-start#java

// Replace this
response.getWriter().println("<h2>RingCentral Authorization Code Flow Authentication</h2><a href="" + rc.authorizeUri(REDIRECT_URI) + "">Login RingCentral Account</a>");

// With this
response.getWriter().println("<h2>RingCentral Authorization Code Flow Authentication</h2><a href="" + rc.authorizeUri("Your-AuthorizeRequest-Object") + "">Login RingCentral Account</a>");            

Phong, Thank you for the quick response. But these examples are in Java and I am not familiar with Java. Do you have the same in Javascript?

Oops, how come I saw it Java??? Too tired.

app.get('/', async function(req, res) {
  var platform = rcsdk.platform()
  if (req.session.tokens != undefined) {
    platform.auth().setData(req.session.tokens)
    if (await platform.loggedIn()) {
      return res.render('test')
    }
  } else {
    res.render('index', {
      authorize_uri: platform.loginUrl({
        redirectUri: RINGCENTRAL_REDIRECT_URL,
        state: "state string",
        ...
      })
    });
  }
})
