Google Cloud SecretManagerServiceClient()找不到带有.from_service_

Question

获取此错误：

google.auth.exceptions.DefaultCredentialsError: Could not automatically determine credentials. Please set GOOGLE_APPLICATION_CREDENTIALS or explicitly create credentials and re-run the application. For more information, please see https://cloud.google.com/docs/authentication/getting-started

使用以下python代码：

from google.cloud import secretmanager
# Create the Secret Manager client.
client = secretmanager.SecretManagerServiceClient().from_service_account_json("app/integrations/google/service_account.json")

在tasks_client = tasks_v2.CloudTasksClient.from_service_account_json(settings.GOOGLE_CLOUD_KEY_FILE_NAME)等其他谷歌服务中使用此from_service_account_json()时，服务帐户信誉正常工作和storage_client = storage.Client.from_service_account_json("app/keys/google-creds.json")

为什么它在这种情况下不起作用？

Answer 1

您需要将函数用作类而不是实例方法：

from google.cloud import secretmanager

client = secretmanager.SecretManagerServiceClient.from_service_account_file(
"/path/to/key.json",
)

或者您可以预先创建凭据：

from google.cloud import secretmanager
from google.oauth2 import service_account
credentials = service_account.Credentials.from_service_account_file(
"/path/to/key.json",
)
client = secretmanager.SecretManagerServiceClient(
credentials=credentials,
)

该方法是有效的，但通常情况下，您会更好地使用应用程序默认凭据来实现可移植性，并将配置排除在代码之外。
