A wrapper over urllib3 that matches httplib2's interface
httplib2shim is a wrapper over httplib2 that uses urllib3 to perform HTTP requests. This library is intended to help existing legacy libraries (and their users) to migrate away from httplib2. It is not intended to be a general purpose replacement for httplib2. It does not support every feature and edge case for httplib2, although contributions are welcome in order to help us cover these cases.
Presently, httplib2shim passes the test suite for httplib2. A few non-applicable tests were disabled, and it’s very possible that the tests do not account for behavior that is depended on by clients.
It’s recommended to install urllib3[secure] before installing httplib2shim:
pip install urllib3[secure] httplib2shim
Usage is straightforward. You can substitute httplib2shim.Http anywhere httplib2.Http is used:
import httplib2shim from oauth2client.client import GoogleCredentials credentials = GoogleCredentials.get_application_default() http = httplib2shim.Http() credentials.authorize(http) # http is now authorized with OAuth2 credentials and uses urllib3 under # the covers.
Alternatively, if you do not control the construction of the Http object, you can use httplib2shim.patch() to monkey-patch the httplib2.Http class to point to httplib2shim.Http():
import httplib2shim httplib2shim.patch() from googleapiclient.discovery import build from oauth2client.client import GoogleCredentials credentials = GoogleCredentials.get_application_default() # build constructs its own httplib2.Http instance. service = build('compute', 'v1', credentials=credentials) # service.http is now a httplib2shim.Http object.
Arguments to the Http constructor will be accepted, but may not make a difference. For instance, ca_certs will have no effect. Instead, pass a urllib3.Pool instance http = httplib2shim.Http(pool=my_pool).
Http.add_certificate is a no-op and will warn.
Probably others, pull requests are welcome to complete the functionality.
