Relative References in URLs

[jtv8]

See 3.1.0 OpenAPI specification:

Relative References in URLs

Unless specified otherwise, all properties that are URLs MAY be relative references as defined by RFC3986. Unless specified otherwise, relative references are resolved using the URLs defined in the Server Object as a Base URL. Note that these themselves MAY be relative to the referring document.

Because the required types for URLs in the Pydanic models are AnyURL, setting them to a relative URL (e.g. setting components -> securitySchemes -> OAuth2PasswordBearer -> flows -> password -> tokenUrl to auth/token) causes the following:

pydantic.error_wrappers.ValidationError:
invalid or missing URL scheme (type=value_error.url.scheme)

For example, this will fail to validate the OpenAPI specs generated by FastAPI when following the OAuth2 security tutorial.

Thanks for the fix! ❤️
