ValueError: Client secrets must be for a web or installed app

Question

我是运行quickstart.py下的示例代码 Python 快速入门我收到以下错误：

ValueError: Client secrets must be for a web or installed app.

我创建了一个具有项目所有者权限的 credentials.json 文件。

错误发生在以下代码段：

if os.path.exists('token.pickle'):
    with open('token.pickle', 'rb') as token:
        creds = pickle.load(token)
# If there are no (valid) credentials available, let the user log in.
if not creds or not creds.valid:
    if creds and creds.expired and creds.refresh_token:
        creds.refresh(Request())
    else:
        flow = InstalledAppFlow.from_client_secrets_file('credentials.json', SCOPES)
        creds = flow.run_local_server()
    # Save the credentials for the next run
    with open('token.pickle', 'wb') as token:
        pickle.dump(creds, token)

我还注意到 token.pickle 文件没有被创建。这是错误输出：

  File "updateSlidev01.py", line 51, in <module>
    main()
  File "updateSlidev01.py", line 31, in main
    flow = InstalledAppFlow.from_client_secrets_file('credentials.json', SCOPES)
  File "/Library/Python/2.7/site-packages/google_auth_oauthlib/flow.py", line 174, in from_client_secrets_file
    return cls.from_client_config(client_config, scopes=scopes, **kwargs)
  File "/Library/Python/2.7/site-packages/google_auth_oauthlib/flow.py", line 147, in from_client_config
    'Client secrets must be for a web or installed app.')
ValueError: Client secrets must be for a web or installed app.

Answer 1

问题是我使用的是在服务帐户密钥管理服务帐户下生成的json，而不是在 OAuth 2.0 客户端 ID 下生成的

Answer 2

对于任何因为想通过 service-account 而不是此 Oauth2 客户端 ID 实际连接到 GCP 日历 API 而来到这里的人，请在原始文件中创建 creds 对象例子如下：

from google.oauth2 import service_account

SCOPES = ['https://www.googleapis.com/auth/calendar.readonly']
SERVICE_ACCOUNT_FILE = '/path/to/service.json'

credentials = service_account.Credentials.from_service_account_file(
        SERVICE_ACCOUNT_FILE, scopes=SCOPES)

假设 service-account 配置了正确的访问权限，这将在不提示用户确认的情况下访问日历。
