I have tried to get a group settings with group settings API using Google App Engine 1.7.5 with python 2.5 following a simple example here. this is my app.yaml:

application: {{APP_ID}}
version: 1
runtime: python
api_version: 1

handlers:
- url: /.*
  script: main.py

and my main.py is like following:

def main():
    application = webapp.WSGIApplication([('/', TestHandler)])
    run_wsgi_app(application)

class TestHandler(webapp.RequestHandler):
    """Handles a request for the query page."""
    def get(self):
        self.response.out.write(Test())

def Test():
    credentials = AppAssertionCredentials(scope='https://www.googleapis.com/auth/apps.groups.settings')
    http = credentials.authorize(httplib2.Http(memcache))
    service = build('groupssettings', 'v1', http=http)
    group = service.groups().get(groupUniqueId='{{GROUP_ID}}').execute()
    logging.error(group)

if __name__=="__main__":
    main()

and this is the stacktrace telling me invalid credentials!

Traceback (most recent call last):
  File "C:\Program Files (x86)\Google\google_appengine\google\appengine\ext\webapp\_webapp25.py", line 714, in __call__
    handler.get(*groups)

Have anyone got this error before or have an idea of the root cause?

您是否通过项目的开发者控制台打开了对组 API 的访问？这是一个简单的步骤，试图让 API 运行的人经常会错过。

此外，我建议使用此处描述的 OAuth 装饰器模式来简化围绕授权流程的推理。

此外，您的 app.yaml 应该指定python27而不仅仅是python. App Engine 运行python27。
