Many thanks for all your hard work on elm-open-api, it's much appreciated! Further to our discussion on Elm Discourse, here's information regarding the problem and the solution I've implemented.
Description
When trying to generate code for an API that uses OAuth2 for security, the following error is generated:
Warning: Todo: Unsupported security schema: Oauth2
at /users/me/ -> GET
To Reproduce
To reproduce this, add the following to the security section of your openapi.json schema file:
I'm passing a json web token around for auth, and I can extend the code generated by elm-open-api relatively easily to enable authentication. For example, I can change the /users/me endpoint, which requires auth, from this:
meUsersMeGet:{ toMsg :Result(OpenApi.Common.ErrorParacosmApi.Types.MeUsersMeGet_ErrorString)ParacosmApi.Types.UserPublic-> msg
-- Next line changed, token :ParacosmApi.Types.Token}->Cmd msg
meUsersMeGet config =Http.request
{ url ="http://127.0.0.1:8000/users/me/", method ="GET"-- Next line changed, headers =[Http.header "Authorization"("Bearer "++ config.token.access_token)], expect =OpenApi.Common.expectJsonCustom
config.toMsg
(Dict.fromList [])ParacosmApi.Json.decodeUserPublic
, body =Http.emptyBody
, timeout =Nothing, tracker =Nothing}
And the API works as expected.
Additional Context
I am a novice when it comes to making OpenAPI compliant APIs, so there's a good chance some of the configuration is wrong on my end. I followed this section of the FastAPI docs to get to this point: https://fastapi.tiangolo.com/tutorial/security/oauth2-jwt/
