If not specified or if None, the urllib3 default timeout will be used. kwargs: Additional arguments passed throught to the underlying urllib3 :meth:`urlopen` method.

This class is used to perform requests to API endpoints that require authorization:: from google.auth.transport.urllib3 import AuthorizedHttp authed_http = AuthorizedHttp(credentials) response = authed_http.request( 'GET', 'https://www.googleapis.com/storage/v1/b') This class implements :class:`urllib3.request.RequestMethods` and can be used just like any other :class:`urllib3.PoolManager`. The underlying :meth:`urlopen` implementation handles adding the credentials' headers to the request and refreshing credentials as needed. This class also supports mutual TLS via :meth:`configure_mtls_channel` method. In order to use this method, the `GOOGLE_API_USE_CLIENT_CERTIFICATE` environment variable must be explicitly set to `true`, otherwise it does nothing. Assume the environment is set to `true`, the method behaves in the following manner: If client_cert_callback is provided, client certificate and private key are loaded using the callback; if client_cert_callback is None, application default SSL credentials will be used. Exceptions are raised if there are problems with the certificate, private key, or the loading process, so it should be called within a try/except block. First we set the environment variable to `true`, then create an :class:`AuthorizedHttp` instance and specify the endpoints:: regular_endpoint = 'https://pubsub.googleapis.com/v1/projects/{my_project_id}/topics' mtls_endpoint = 'https://pubsub.mtls.googleapis.com/v1/projects/{my_project_id}/topics' authed_http = AuthorizedHttp(credentials) Now we can pass a callback to :meth:`configure_mtls_channel`:: def my_cert_callback(): # some code to load client cert bytes and private key bytes, both in # PEM format. some_code_to_load_client_cert_and_key() if loaded: return cert, key raise MyClientCertFailureException() # Always call configure_mtls_channel within a try/except block. try: is_mtls = authed_http.configure_mtls_channel(my_cert_callback) except: # handle exceptions. if is_mtls: response = authed_http.request('GET', mtls_endpoint) else: response = authed_http.request('GET', regular_endpoint) You can alternatively use application default SSL credentials like this:: try: is_mtls = authed_http.configure_mtls_channel() except: # handle exceptions. Args: credentials (google.auth.credentials.Credentials): The credentials to add to the request. http (urllib3.PoolManager): The underlying HTTP object to use to make requests. If not specified, a :class:`urllib3.PoolManager` instance will be constructed with sane defaults. refresh_status_codes (Sequence[int]): Which HTTP status codes indicate that credentials should be refreshed and the request should be retried. max_refresh_attempts (int): The maximum number of times to attempt to refresh the credentials and retry the request. default_host (Optional[str]): A host like "pubsub.googleapis.com". This is used when a self-signed JWT is created from service account credentials.

The behavior is controlled by `GOOGLE_API_USE_CLIENT_CERTIFICATE` environment variable. (1) If the environment variable value is `true`, the function returns True if the channel is mutual TLS and False otherwise. The `http` provided in the constructor will be overwritten. (2) If the environment variable is not set or `false`, the function does nothing and it always return False. Args: client_cert_callback (Optional[Callable[[], (bytes, bytes)]]): The optional callback returns the client certificate and private key bytes both in PEM format. If the callback is None, application default SSL credentials will be used. Returns: True if the channel is mutual TLS and False otherwise.
