Question

我编写了一个身份验证代码并获得了一个访问令牌，但当我用它来抓取一个对象时，我最终得到了'NoneType' object is not callable。

 Exception Location: googleads\adwords.py in GetService, line 365
 Exception Type: Type Error
 Exception Value: Internal Server Error: /oauth2callback

无论是调用Customer还是CampaignService，我都得到相同的结果。我不明白我做错了什么。

我正在关注Googleads中的代码。

def getAdwordsFlow():
    FLOW.redirect_uri = 'http://localhost/oauth2callback'

    # Generate URL for request to Google's OAuth 2.0 server.
    authorization_url, state = FLOW.authorization_url(
        access_type='offline',
        include_granted_scopes='true')
    return authorization_url


def getAdwordsTokens(request):
    auth_code = request.GET.get('code')
    FLOW.fetch_token(code=auth_code)
    credentials = FLOW.credentials

    oauth2_client = oauth2.GoogleAccessTokenClient(
    FLOW.credentials.token, FLOW.credentials.expiry)

    adwords_client = adwords.AdWordsClient(
    "DEVELOPER-TOKEN", oauth2_client, "USER-AGENT", "CLIENT-CUSTOMER-ID")

    customer = adwords_client.GetService('CustomerService').getCustomers()[0]
    print('You are logged in as customer: %s' % customer['customerId'])

    return HttpResponseRedirect("/")

url.py

urlpatterns = [
    re_path(r'^oauth2callback', queries.getAdwordsTokens, name='auth_calledback'),] #How

view.py

def index(request):
    return redirect(getAdwordsFlow())

终端输出：

"GET /oauth2callback?state=XXXXXXXXX&code=4/XXXXXXXXXXX&scope=https://www.googleapis.com/auth/adwords+https://www.googleapis.com/auth/userinfo.profile+https://www.googleapis.com/auth/userinfo.email HTTP/1.1" 500 80213 为什么是500？

当我呼叫它时，我注意到我的访问令牌具有不同的值。所以我假设它在工作。

根据您的问题，您的服务电话是 -

GET / oauth2callback？state = XXXXXXXXX＆amp; code = 4 / XXXXXXXXXXX＆amp; scope = https://www.googleapis.com/auth/adwords+https://www.googleapis.com/auth/userinfo.profile+https://www.googleapis.com/auth/userinfo.email HTTP / 1.1

此次调用既不是获取访问令牌调用，也不是请求中的access_token，并且根据您的reference代码，它将从access_token生成refresh_token。

def main(access_token, token_expiry, client_customer_id, developer_token,
         user_agent):
  oauth2_client = oauth2.GoogleAccessTokenClient(access_token, token_expiry)

  adwords_client = adwords.AdWordsClient(
      developer_token, oauth2_client, user_agent,
      client_customer_id=client_customer_id)

  customer = adwords_client.GetService('CustomerService').getCustomers()[0]
  print 'You are logged in as customer: %s' % customer['customerId']


if __name__ == '__main__':
  args = parser.parse_args()

  # Retrieve a new access token for use in this example. In a production
  # application, you may use a credential store to share access tokens for a
  # given user across applications.
  oauth2credentials = client.OAuth2Credentials(
      None, args.client_id, args.client_secret, args.refresh_token,
      datetime.datetime(1980, 1, 1, 12), GOOGLE_OAUTH2_ENDPOINT,
      USER_AGENT)

  oauth2credentials.refresh(httplib2.Http())

  main(oauth2credentials.access_token, oauth2credentials.token_expiry,
       args.client_customer_id, args.developer_token, USER_AGENT)

为了使用您的代码，首先使用this code生成refresh_token，然后在您的代码中使用它。

基本的Google API Oauth2身份验证安装程序无法提供对象？
