Question

我正在尝试使用python客户端库从DCM下载报告。我正在使用服务帐户，并且正在使用此链接代码this!。我已经按照所有步骤设置了DCM api网址中提到的服务帐户文件，但是在运行代码时遇到了错误提示。

回溯（最近通话最近）： _validate_clientsecrets中的文件“ /usr/bin/anaconda/envs/py35/lib/python3.5/site-packages/oauth2client/clientsecrets.py”，第86行（client_type，client_info），= clientsecrets_dict.items（） ValueError：太多值无法解包（预期1）

我正在使用以下服务帐户文件连接到DCM API并下载报告。这是我要设置的过程，以便每天自动下载报告，而无需任何手动干预。

        for profile in response['items']:
            print('Found user profile with ID %s and user name "%s".' %(profile['profileId'], profile['userName']))
