[Question] send id_token from google js api credential to callback

[arpu]

Hi,

tested some options with the newer google api from https://developers.google.com/identity/gsi/web/reference/js-reference?hl=en

the response is jwtToken credential

How i understand the omniauth-google-oauth2 i need to POST the id_token= the JWToken ?

and set the server option provider_ignores_state: true ( found in the README )

but i get

self.access_token = access_token.refresh! if access_token.expired?
 ^^^^^^^^^: NoMethodError, undefined method `expired?' for nil:NilClass

any idea?

There is a JS example at:

https://github.com/zquestz/omniauth-google-oauth2/blob/master/examples/config.ru

I believe you will want to pass access_token.

Hi @zquestz

Thanks, this example just works with the code response from the google

but not with the newer credential using POST params like

const req = {"access_token": response.credential}

error is :

(google_oauth2) Authentication failure! invalid_credentials: OAuth2::Error, Invalid Value
 {
"error_description": "Invalid Value"
 }

setting the header for axios axios.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest'; does not change the error

[arpu]

if i am right the new credentials should be confirmend with

  payload = Google::Auth::IDTokens.verify_oidc(params[:credential], aud: ENV['GOOGLE_CLIENT_ID'])

described in this blog post https://patrickkarsh.medium.com/how-to-add-google-one-touch-authentication-to-a-ruby-on-rails-application-6ac8776c4190

How is this now? Is there a working example of js implementation? Also, the script in the readme is of a legacy google lib that has lost support already

[zquestz]

There is no working example right now. Would definitely be open to a PR to update the docs and client side JS implementation.

Please forgive me if I'm getting this wrong, but are you seriously asking the person who can't get it to work to update the docs on how to get it working?

No, just saying the docs could use a new example and letting people who read this thread know it would be nice to get it updated.
