google.oauth2.credentials module¶

OAuth 2.0 Credentials.

This module provides credentials based on OAuth 2.0 access and refresh tokens. These credentials usually access resources on behalf of a user (resource owner).

Specifically, this is intended to use access tokens acquired using the Authorization Code grant and can refresh those tokens using a optional refresh token.

Obtaining the initial access and refresh token is outside of the scope of this module. Consult rfc6749 section 4.1 for complete details on the Authorization Code grant flow.

class Credentials(token, refresh_token=None, id_token=None, token_uri=None, client_id=None, client_secret=None, scopes=None, default_scopes=None, quota_project_id=None, expiry=None, rapt_token=None)[source]¶

Bases: google.auth.credentials.ReadOnlyScoped, google.auth.credentials.CredentialsWithQuotaProject

Credentials using OAuth 2.0 access and refresh tokens.

The credentials are considered immutable. If you want to modify the quota project, use with_quota_project() or

credentials = credentials.with_quota_project('myproject-123)

If reauth is enabled, pyu2f dependency has to be installed in order to use security key reauth feature. Dependency can be installed via pip install pyu2f or pip install google-auth[reauth].

Parameters:

token (Optional(str)) – The OAuth 2.0 access token. Can be None if refresh information is provided.
refresh_token (str) – The OAuth 2.0 refresh token. If specified, credentials can be refreshed.
id_token (str) – The Open ID Connect ID Token.
token_uri (str) – The OAuth 2.0 authorization server’s token endpoint URI. Must be specified for refresh, can be left as None if the token can not be refreshed.
client_id (str) – The OAuth 2.0 client ID. Must be specified for refresh, can be left as None if the token can not be refreshed.
client_secret (str) – The OAuth 2.0 client secret. Must be specified for refresh, can be left as None if the token can not be refreshed.
scopes (Sequence [ str ]) – The scopes used to obtain authorization. This parameter is used by has_scopes(). OAuth 2.0 credentials can not request additional scopes after authorization. The scopes must be derivable from the refresh token if refresh information is provided (e.g. The refresh token scopes are a superset of this or contain a wild card scope like ‘https://www.googleapis.com/auth/any-api’).
default_scopes (Sequence [ str ]) – Default scopes passed by a Google client library. Use ‘scopes’ for user-defined scopes.
quota_project_id (Optional [ str ]) – The project ID used for quota and billing. This project may be different from the project used to create the credentials.
rapt_token (Optional [ str ]) – The reauth Proof Token.

refresh_token¶

The OAuth 2.0 refresh token.

Type:	`Optional` [ `str` ]

scopes¶

The OAuth 2.0 permission scopes.

Type:	`Optional` [ `str` ]

token_uri¶

The OAuth 2.0 authorization server’s token endpoint URI.

Type:	`Optional` [ `str` ]

id_token¶

The Open ID Connect ID Token.

Depending on the authorization server and the scopes requested, this may be populated when credentials are obtained and updated when refresh() is called. This token is a JWT. It can be verified and decoded using google.oauth2.id_token.verify_oauth2_token().

Type:	`Optional` [ `str` ]

client_id¶

The OAuth 2.0 client ID.

Type:	`Optional` [ `str` ]

client_secret¶

The OAuth 2.0 client secret.

Type:	`Optional` [ `str` ]

requires_scopes¶

OAuth 2.0 credentials have their scopes set when the initial token is requested and can not be changed.

Type:	False

rapt_token¶

The reauth Proof Token.

Type:	`Optional` [ `str` ]

with_quota_project(quota_project_id)[source]¶

Returns a copy of these credentials with a modified quota project.

Parameters:	quota_project_id (str) – The project to use for quota and billing purposes
Returns:	A new credentials instance.
Return type:	google.oauth2.credentials.Credentials

refresh(request)[source]¶

Refreshes the access token.

Parameters:	request (google.auth.transport.Request) – The object used to make HTTP requests.
Raises:	`google.auth.exceptions.RefreshError` – If the credentials could not be refreshed.

classmethod from_authorized_user_info(info, scopes=None)[source]¶

Creates a Credentials instance from parsed authorized user info.

Parameters:	info (`Mapping` [ `str`, `str` ]) – The authorized user info in Google format. scopes (`Sequence` [ `str` ]) – Optional list of scopes to include in the credentials.
Returns:	The constructed credentials.
Return type:	google.oauth2.credentials.Credentials
Raises:	`ValueError` – If the info is not in the expected format.

classmethod from_authorized_user_file(filename, scopes=None)[source]¶

Creates a Credentials instance from an authorized user json file.

Parameters:	filename (str) – The path to the authorized user json file. scopes (`Sequence` [ `str` ]) – Optional list of scopes to include in the credentials.
Returns:	The constructed credentials.
Return type:	google.oauth2.credentials.Credentials
Raises:	`ValueError` – If the file is not in the expected format.

to_json(strip=None)[source]¶

Utility function that creates a JSON representation of a Credentials object.

Parameters:	strip (`Sequence` [ `str` ]) – Optional list of members to exclude from the generated JSON.
Returns:	A JSON representation of this instance. When converted into a dictionary, it can be passed to from_authorized_user_info() to create a new credential instance.
Return type:	str

apply(headers, token=None)[source]¶

Apply the token to the authentication header.

Parameters:	headers (Mapping) – The HTTP request headers. token (`Optional` [ `str` ]) – If specified, overrides the current access token.

before_request(request, method, url, headers)[source]¶

Performs credential-specific before request logic.

Refreshes the credentials if necessary, then calls apply() to apply the token to the authentication header.

Parameters:	request (google.auth.transport.Request) – The object used to make HTTP requests. method (str) – The request’s HTTP method or the RPC method being invoked. url (str) – The request’s URI or the RPC service’s URI. headers (Mapping) – The request’s headers.

default_scopes¶

the credentials’ current set of default scopes.

Type:	`Sequence` [ `str` ]

expired¶

Checks if the credentials are expired.

Note that credentials can be invalid but not expired because Credentials with expiry set to None is considered to never expire.

has_scopes(scopes)¶

Checks if the credentials have the given scopes.

Parameters:	scopes (`Sequence` [ `str` ]) – The list of scopes to check.
Returns:	True if the credentials have the given scopes.
Return type:	bool

quota_project_id¶: Project to use for quota and billing purposes.

valid¶

Checks the validity of the credentials.

This is True if the credentials have a token and the token is not expired.

class UserAccessTokenCredentials(account=None, quota_project_id=None)[source]¶

Bases: google.auth.credentials.CredentialsWithQuotaProject

Access token credentials for user account.

Obtain the access token for a given user account or the current active user account with the gcloud auth print-access-token command.

Parameters:	account (`Optional` [ `str` ]) – Account to get the access token for. If not specified, the current active account will be used. quota_project_id (`Optional` [ `str` ]) – The project ID used for quota and billing.

with_account(account)[source]¶

Create a new instance with the given account.

Parameters:	account (str) – Account to get the access token for.
Returns:	The created credentials with the given account.
Return type:	google.oauth2.credentials.UserAccessTokenCredentials
