我正在尝试使用 ServicePrincipalCredentials 类连接到 blob 存储，但我随机收到此错误：
Error adal-python OAuth2Client:Get Token request failed
我用来连接到 blob 存储的代码如下：
from azure.common.credentials import ServicePrincipalCredentials from azure.storage.blob import BlockBlobService from azure.storage.common import TokenCredential credentials = ServicePrincipalCredentials(client_id=client_id, secret=secret, tenant=tenant, resource=resource) token_credential = TokenCredential(credentials.token["access_token"]) blob_ service = BlockBlobService(account_name=account_name, token_credential=token_credential)
因此，连接一旦工作正常，但在不同时间调用它时，在初始化类ServicePrincipalCredentials时会从上面给出错误。我正在使用 account_name 中的“-secondary”后缀访问存储帐户的辅助终结点。
有什么办法可以防止这种情况发生吗？
错误的完整跟踪如下：
