This page contains important information about the thread safety of this library.
The httplib2.Http() objects are not thread-safe
The google-api-python-client library is built on top of the
httplib2
library, which is not thread-safe.
Therefore, if you are running as a multi-threaded application,
each thread that you are making requests from must have its own instance of httplib2.Http().
The easiest way to provide threads with their own httplib2.Http() instances is to either
override the construction of it within the service object or to pass an instance via
the http argument to method calls.
# Create a new Http() object for every requestdefbuild_request(http, *args, **kwargs):
new_http=httplib2.Http()
returngoogleapiclient.http.HttpRequest(new_http, *args, **kwargs)
service=build('api_name', 'api_version', requestBuilder=build_request)
# Pass in a new Http() manually for every requestservice=build('api_name', 'api_version')
http=httplib2.Http()
service.stamps().list().execute(http=http)
Credential Storage objects are thread-safe
All
Storage
objects defined in this library are thread-safe,
and multiple processes and threads can operate on a single store.
In some cases, this library automatically refreshes expired OAuth 2.0 tokens.
When many threads are sharing the same set of credentials,
the threads cooperate to minimize the total number of token refresh requests
sent to the server.
