By: CenturyBoysA simple route decorator JWT scope validator.This project work with the follow frameworks:✅FastApi✅aiohttpConfigConfiguration are exposed and can be set in any time including out of the use scope.Obs: all configs are saved as singleton.jwkThe jwk key to validate JWT can be bytes, str or dict. This config need to be set!http_header_name_tokenIf your application use a custom header to send the authentication token you can use this param to indicate his name. By default, the value is 'Authorization'request_token_callbackIf to extract the request token you need to perform some operation you can set a callback for it. Will receive the request as param and must return a str with token type and the token 'Basic XXX'importauth2guardclassRequest:def__init__(self,headers:dict):self._headers=headers@propertydefheaders(self)->dict:returnself._headersclassrequest=Request(headers={"x-token":f"Basic Akj817Hakn122i..."})defrequest_token_callback(request:Request):returnrequest.headers.get("x-token")auth2guard.set_config(jwk='{"p":"-7pCvLlzsNIRD7utbLZqB...',http_header_name_token="x-token",request_token_callback=request_token_callback)ExceptionsThe package raise exceptions for some cases se bellow.Obs: By default, all exception are ValueError.token_not_foundError when token was not found.Obs: The configrequest_token_callbackcan be the problem.not_from_originError when token was generated not by the giving JWK.Obs: Validate the config jwk.expiredError when exp JWT param exceeded the time.unauthorizedError when the JWT has not all necessary scope to proceed.importauth2guardclassMyException(Exception):passauth2guard.overwrite_exceptions(unauthorized=MyException)ValidatorCan be used as decorator and receive a list of scopes. The validator will operate AND validation or a OR validation with the token scope content. For the AND validation all scopes in theallowed_scopesparam need to be present in the jwt scope and in the OR if any scope is present that's enough. You can receive the token content if you want by settingtoken_contenttoTruethis will inject the paramtoken_content: dictinto your function askwargsimportauth2guardclassRequest:def__init__(self,headers:dict):self._headers=headers@propertydefheaders(self)->dict:returnself._headersauth2guard.set_config(jwk='{"p":"-7pCvLlzsNIRD7utbLZqB...')@auth2guard.validate(allowed_scopes=["test1"],scope_and_validation=True,inject_token_content=True,allowed_audiences=["test1"],audience_and_validation=True)defroute_callback(request,token_content:dict):passrequest=Request(headers={"Authorization":f"Basic XXX"})route_callback(request=request)
