| // Google OAuth callback proxy on the docdoe.in domain. | |
| // | |
| // WHY: Google's consent screen shows the host of the OAuth redirect_uri. When | |
| // that points straight at the backend (asnannp-docdoeai.hf.space) the screen | |
| // reads "to continue to asnannp-docdoeai.hf.space". Registering THIS route as | |
| // the redirect_uri makes Google show "to continue to www.docdoe.in" instead. | |
| // | |
| // FLOW: | |
| // Google -> https://www.docdoe.in/api/auth/google/callback?code=..&state=.. | |
| // -> 302 to <backend>/auth/google/callback?code=..&state=.. | |
| // -> backend exchanges the code (redirect_uri must equal THIS url) | |
| // -> backend 302s to /auth/google/callback#access_token=.. (frontend page) | |
| // | |
| // REQUIRED config to activate (do these together): | |
| // * HF Space env: GOOGLE_OAUTH_REDIRECT_URI=https://www.docdoe.in/api/auth/google/callback | |
| // * Google Console -> Clients -> Authorized redirect URIs: add the same URL | |
