如何使用 Python 连接到 GCP BigTable

Question

在我的环境变量中设置“GOOGLE_APPLICATION_CREDENTIALS”后，我正在使用 python（google-cloud-bigtable 库）连接到我的 GCP BigTable 实例。我成功了。

但是，我的要求是我想在创建 BigTable 客户端对象时在运行期间传递凭据，如下所示：

client = bigtable.Client(credentials='82309281204023049', project='xjkejfkx')

我已按照 GCP BigTable Client Documentation 连接到 GCP BigTable，但出现此错误：

Traceback (most recent call last):
  File "D:/testingonlyinformix/bigtable.py", line 14, in <module>
    client = bigtable.Client(credentials="9876543467898765", project="xjksjkdn", admin=True)
  File "D:\testingonlyinformix\new_venv\lib\site-packages\google\cloud\bigtable\client.py", line 196, in __init__
    project=project, credentials=credentials, client_options=client_options,
  File "D:\testingonlyinformix\new_venv\lib\site-packages\google\cloud\client\__init__.py", line 320, in __init__
    self, credentials=credentials, client_options=client_options, _http=_http
  File "D:\testingonlyinformix\new_venv\lib\site-packages\google\cloud\client\__init__.py", line 167, in __init__
    raise ValueError(_GOOGLE_AUTH_CREDENTIALS_HELP)
ValueError: This library only supports credentials from google-auth-library-python. See https://google-auth.readthedocs.io/en/latest/ for help on authentication with this library.

有人可以建议 fields/attributes 一个 Client 对象在建立连接的运行时间内期望的所有内容吗到 GCP BigTable？

谢谢

Answer 1

经过 2 小时的搜索，我终于找到了这些页面，请按顺序查看它们：

from google_auth_oauthlib import flow

appflow = flow.InstalledAppFlow.from_client_secrets_file(
    "client_secrets.json", scopes=["https://www.googleapis.com/auth/bigtable.admin"])

appflow.run_console()
credentials = appflow.credentials

上一步中的credentials需要提供给BigTableclient对象：

client = bigtable.Client(credentials=credentials, project='xjkejfkx')

这个解决方案对我有用，如果有人有任何其他建议，请pitch-in。
