无法验证Google AnalyticsAPI的批量请求。
我有一个凭证.json文件，看起来像这样。
{
"type": "service_account",
"project_id": "xxx",
"private_key_id": "xxx",
"private_key": "xxx",
"client_email": "xxx",
"client_id": "xxx",
"client_secret":"xxx",
"auth_uri": "xxx",
"token_uri": "xxx",
"auth_provider_x509_cert_url": "xxx",
"client_x509_cert_url": "xxx"
}
这是我的回调函数
def test_callback(request_id, response, exception):
"""Handle batched request responses."""
print request_id
if exception is not None:
if isinstance(exception, HttpError):
message = json.loads(exception.content)['error']['message']
print ('Request %s returned API error : %s : %s ' %
(request_id, exception.resp.status, message))
else:
print response
这是我验证的地方
"""Init and return the Google Analytics service"""
CREDS = 'credentials/google.json'
scopes = ['https://www.googleapis.com/auth/analytics.readonly']
credentials = ServiceAccountCredentials.from_json_keyfile_name(CREDS, scopes)
http = httplib2.Http()
http = credentials.authorize(http)
这是我尝试添加批量请求的地方

我继续在终端

This is my full .py file. I am assuming it has something to do with my authentication process but I can't seem to figure it out. If someone could help point me in the right direction it would help.
