我有一个触发器类型设置为 HTTP 的云函数，并且还有一个有权调用云函数的服务帐户。我想从 python 脚本调用云函数。我使用以下脚本来调用该函数：
from google.oauth2 import service_account
from google.auth.transport.urllib3 import AuthorizedHttp
credentials = service_account.Credentials.from_service_account_file('/path/to/service-account-credentials.json')
scoped_credentials = credentials.with_scopes(['https://www.googleapis.com/auth/cloud-platform'])
authed_http = AuthorizedHttp(scoped_credentials)
response = authed_http.request('GET', 'https://test-123456.cloudfunctions.net/my-cloud-function')
print(response.status)
我收到未经授权 (401) 错误响应。这是正确的调用方式吗？
为了能够调用您的云函数，您需要针对 Cloud Functions 端点的 ID 令牌
from google.oauth2 import service_account
from google.auth.transport.requests import AuthorizedSession
url = 'https://test-123456.cloudfunctions.net/my-cloud-function'
creds = service_account.IDTokenCredentials.from_service_account_file(
'/path/to/service-account-credentials.json', target_audience=url)
authed_session = AuthorizedSession(creds)
# make authenticated request and print the response, status_code
resp = authed_session.get(url)
print(resp.status_code)
print(resp.text)
