Client API References

This part of the documentation covers the interface of Authlib Client.

Sessions and Client

class authlib.client.OAuth1Session(client_id, client_secret=None, token=None, token_secret=None, redirect_uri=None, rsa_key=None, verifier=None, signature_method='HMAC-SHA1', signature_type='HEADER', force_include_body=False, **kwargs)
create_authorization_url(url, request_token=None, **kwargs)

Create an authorization URL by appending request_token and optional kwargs to url.

This is the second step in the OAuth 1 workflow. The user should be redirected to this authorization URL, grant access to you, and then be redirected back to you. The redirection back can either be specified during client registration or by supplying a callback URI per request.

Parameters:
  • url – The authorization endpoint URL.
  • request_token – The previously obtained request token.
  • kwargs – Optional parameters to append to the URL.
Returns:

The authorization URL with new parameters embedded.
fetch_access_token(url, verifier=None, **kwargs)

Method for fetching an access token from the token endpoint.

This is the final step in the OAuth 1 workflow. An access token is obtained using all previously obtained credentials, including the verifier from the authorization step.

Parameters:
  • url – Access Token endpoint.
  • verifier – A verifier string to prove authorization was granted.
  • kwargs – Extra parameters to include for fetching access token.
Returns:

A token dict.
fetch_request_token(url, realm=None, **kwargs)

Method for fetching an access token from the token endpoint.

This is the first step in the OAuth 1 workflow. A request token is obtained by making a signed post request to url. The token is then parsed from the application/x-www-form-urlencoded response and ready to be used to construct an authorization url.

Parameters:
  • url – Request Token endpoint.
  • realm – A string/list/tuple of realm for Authorization header.
  • kwargs – Extra parameters to include for fetching token.
Returns:

A Request Token dict.

Note, realm can also be configured when session created:

session = OAuth1Session(client_id, client_secret, ..., realm='')
parse_authorization_response(url)

Extract parameters from the post authorization redirect response URL.

Parameters:url – The full URL that resulted from the user being redirected back from the OAuth provider to you, the client.
Returns:A dict of parameters extracted from the URL.
class authlib.client.OAuth1Auth(client_id, client_secret=None, token=None, token_secret=None, redirect_uri=None, rsa_key=None, verifier=None, signature_method='HMAC-SHA1', signature_type='HEADER', realm=None, force_include_body=False)

  • token – A dict of token attributes such as access_token, token_type and expires_at.
  • token_placement – The place to put token in HTTP request. Available values: “header”, “body”, “uri”.
  • token_updater – A function for you to update token. It accept a OAuth2Token as parameter.
create_authorization_url(url=None, state=None, code_verifier=None, **kwargs)
