Google does not return refresh token without access_type=offline in the auth url.

[rio]

This can be resolved luckily without code changes by adding it tot the authorization url set in the configuration.

This is did not fix it for me, I've tried using offline instead of offline_access as well.

https://github.com/heptiolabs/gangway/blob/master/docs/google.md#configuring-gangway mentions to leave offline out, but as @rio mentions, there is no refresh token.

@VihanAgarwal97, make sure you add access_type=offline to your auth url like so: https://accounts.google.com/o/oauth2/v2/auth?access_type=offline

Still missing a refresh token.

apiVersion: v1
data:
  gangway.yaml: >
    apiServerURL: <redacted>

    audience: https://${DNS_NAME}/userinfo

    authorizeURL:
    https://accounts.google.com/o/oauth2/v2/auth?access_type=offline

    clientID: ${GANGWAY_CLIENT_ID}

    clientSecret: ${GANGWAY_CLIENT_SECRET}

    clusterName: <redacted>

    port: 8080

    redirectURL: <redacted>

    scopes:

    - openid

    - profile

    - email

    tokenURL: https://www.googleapis.com/oauth2/v4/token

    usernameClaim: email

I'm using the helm chart to deploy -

      # Values file as block file
      values: |
        gangway:
          scopes: ["openid", "profile", "email"]
          apiServerURL: "<redacted>"
          authorizeURL: "https://accounts.google.com/o/oauth2/v2/auth?access_type=offline"
          tokenURL: "https://www.googleapis.com/oauth2/v4/token"
          clusterName: <redacted>
          # Where to redirect back to. This should be a URL
          redirectURL: "<redacted>/callback"
          usernameClaim: "email"
        env: 
        - name: GANGWAY_SESSION_SECURITY_KEY
          valueFrom:
            secretKeyRef:
              name: gangway-test-key
              key: sessionkey 
        - name: GANGWAY_AUDIENCE
          valueFrom:
            secretKeyRef:
              name: gangway-secret 
              key: client_id # For Google OAuth, clientID is the same as audience
        - name: GANGWAY_CLIENT_ID
          valueFrom:
            secretKeyRef:
              name: gangway-secret 
              key: client_id
        - name: GANGWAY_CLIENT_SECRET
          valueFrom:
            secretKeyRef:
              name: gangway-secret
              key: client_secret

@rio the docs specify a different url, I'm not sure what to use.
https://github.com/heptiolabs/gangway/blob/master/docs/google.md#configuring-gangway
This is currently blocking us from using this in prod.

google only issues refresh tokens once per login. To get a refresh token again remove your third party integration from accounts.google.com from your account then login again.
