`InMemoryOAuthProvider`

An in-memory OAuth provider for testing purposes. It simulates the OAuth 2.1 flow locally without external calls. Methods:

`get_client`

get_client(self, client_id: str) -> OAuthClientInformationFull | None

`register_client`

register_client(self, client_info: OAuthClientInformationFull) -> None

`authorize`

authorize(self, client: OAuthClientInformationFull, params: AuthorizationParams) -> str

Simulates user authorization and generates an authorization code. Returns a redirect URI with the code and state.

`load_authorization_code`

load_authorization_code(self, client: OAuthClientInformationFull, authorization_code: str) -> AuthorizationCode | None

`exchange_authorization_code`

exchange_authorization_code(self, client: OAuthClientInformationFull, authorization_code: AuthorizationCode) -> OAuthToken

`load_refresh_token`

load_refresh_token(self, client: OAuthClientInformationFull, refresh_token: str) -> RefreshToken | None

`exchange_refresh_token`

exchange_refresh_token(self, client: OAuthClientInformationFull, refresh_token: RefreshToken, scopes: list[str]) -> OAuthToken

`load_access_token`

load_access_token(self, token: str) -> AccessToken | None

`verify_token`

verify_token(self, token: str) -> AccessToken | None

Verify a bearer token and return access info if valid. This method implements the TokenVerifier protocol by delegating to our existing load_access_token method. Args:

token: The token string to validate

Returns:

AccessToken object if valid, None if invalid or expired

`revoke_token`

revoke_token(self, token: AccessToken | RefreshToken) -> None

Revokes an access or refresh token and its counterpart.
