我正在尝试在Google Cloud函数中创建Blogger API服务对象。我引用https://cloud.google.com/docs/authentication/production#providing_credentials_to_your_application中的示例（“在Compute Engine，Kubernetes Engine，App Engine flexible环境和Cloud Functions上获取凭据”一节）
给出的示例适用于Google Starage。我正在尝试将其转换为Blogger API的Google API客户端。我找不到有关如何使用此默认凭据创建Blogger API服务对象的文档。我尝试重用
中的代码我尝试了以下代码，但出现错误。我知道这是错误的，但是我没有关于如何使用此证书的文档。
from google.auth import compute_engine
import googleapiclient.discovery
credentials = compute_engine.Credentials()
print(type(credentials))
blogger = googleapiclient.discovery.build('blogger', 'v3', credentials=credentials)
print(blogger)
我收到以下错误：
