AuthorizedHttp

✓ from google_auth_httplib2 import AuthorizedHttp

Ensure to use google_auth_httplib2 instead of older versions.

This quickstart shows you how to use AuthorizedHttp with Google Authentication Library.

import os from google.auth.transport.requests import Request from google_auth_httplib2 import AuthorizedHttp credentials = ... # Obtain your credentials here http = AuthorizedHttp(credentials)

Debug

Known issues

breakingRequires httplib2 >= 0.19.0 and < 1.0.0 from version 0.2.1.

fix

Upgrade httplib2 to a compatible version.

affects: <= 0.2.0

deprecatedOlder versions of this library may use deprecated imports.

fix

Use the updated import paths.

affects: <0.3.0

breakingThe `requests` library, a dependency for Google authentication transport, is missing, leading to `ImportError: No module named 'requests'`.

fix

Ensure the `requests` package is installed (e.g., `pip install requests`). If this library uses `google-auth` and its requests transport, confirm that `requests` is included in your project's dependencies or install `google-auth[requests]`.

affects: *

breakingThe library failed with a ModuleNotFoundError for 'requests', indicating that the 'requests' package, a required dependency for 'google.auth.transport.requests', is not installed.

fix

Ensure the 'requests' library is installed in the environment (e.g., 'pip install requests').

affects: *

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'google_auth_httplib2'

This error occurs when the 'google-auth-httplib2' package is not installed in the Python environment, or if there's an environment conflict (e.g., with Google App Engine's bundled 'google' module).

fix

Ensure the package is installed using pip: `pip install google-auth-httplib2`. If on App Engine, ensure correct vendoring or environment configuration to resolve module path conflicts.

ValueError: Credentials from google.auth specified, but google-api-python-client is unable to use these credentials unless google-auth-httplib2 is installed. Please install google-auth-httplib2.

The `google-api-python-client` library requires `google-auth-httplib2` to be installed when authenticating with `google-auth` credentials, as it provides the necessary HTTP transport.

fix

Install the required transport library: `pip install google-auth-httplib2`.

AttributeError: 'Credentials' object has no attribute 'authorize'

This error typically arises when using `google-auth` credentials with an older version of `google-api-python-client` or code expecting `oauth2client` style credentials, which had an `authorize` method. `google-auth-httplib2` acts as a bridge for `google-auth` credentials to work with `google-api-python-client`'s expectations.

fix

Ensure `google-auth-httplib2` is installed: `pip install google-auth-httplib2`. Also, verify `google-api-python-client` is up-to-date: `pip install --upgrade google-api-python-client`.

httplib2 transport does not support per-request timeout. Set the timeout when constructing the httplib2.Http instance.

This message, often a warning, indicates that a per-request timeout was attempted with a version of `google-auth` that doesn't propagate it correctly to the `httplib2` transport. The timeout needs to be set directly on the `httplib2.Http` instance used by `google-auth-httplib2`.

fix

When initializing `httplib2.Http`, pass the timeout argument, for example: `http = httplib2.Http(timeout=30)`. Then use this `http` instance when creating `google.auth.transport.httplib2.AuthorizedHttp`.
