Question

我尝试使用带有python 2.5的Google App Engine 1.7.5按照简单示例here获取组设置API的组设置。这是我的app.yaml：

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

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

我的main.py如下：

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()

这是堆栈跟踪告诉我无效的凭据！

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)

    self.response.out.write(Test())
  File "D:\Projets\GS\main.py", line 41, in Test
    group = service.groups().get(groupUniqueId='{{GROUP_ID}}').execute()

    raise HttpError(resp, content, uri=self.uri)
HttpError: <HttpError 401 when requesting https://www.googleapis.com/groups/v1/groups/{{GROUP_ID}}?alt=json returned "Invalid Credentials">

有没有人在此之前得到此错误或了解根本原因？

Answer 1

您是否通过项目的开发者控制台打开了对组API的访问权限？这是一个简单的步骤，人们经常会错过这个步骤。

另外，我建议使用OAuth as described here的装饰器模式来简化授权流程的推理。

此外，您的app.yaml应指定python27而非python。 App Engine运行python27。

带有服务帐户的Google AppEngine但凭据无效
