GCP-无法通过身份验证来调用Google Cloud功能

我有一个名为rad_format_text_v0的云函数。我(andy@onehot.io)有权调用它,如下所示:

$ gcloud beta functions get-iam-policy rad_format_text_v0
bindings:
- members:
  - allAuthenticatedUsers
  - user:andy@onehot.io
  role: roles/cloudfunctions.invoker
etag: BwWOSfjYxp0=
version: 1

我可以使用gcloud functions call ...

调用它
$ gcloud auth list
           Credentialed Accounts
ACTIVE             ACCOUNT
*                  andy@onehot.io

$ gcloud functions call rad_format_text_v0 --data "$(< test.json)"
executionId: 2wm7nrgc0vjo
result: |
  ["REDACTED successful result"]

但是,当我尝试使用另一个curl之类的HTTP客户端时,即使我传递了身份验证令牌,它也失败了...

$ curl -i -X POST "https://us-central1-onehot-autocoder.cloudfunctions.net/rad_format_text_v0" -H "Content-Type:application/json" -H "Authorization: bearer $(gcloud auth application-default print-access-token)" --data @test.json

我完全按照documentation中的说明进行了操作。我不知道为什么我的令牌不起作用。

答案 0 :(得分:1)

您正在使用gcloud auth application-default print-access-token来获取令牌,并且共享的文档指定您应该改用gcloud auth print-identity-token命令。

我对其进行了测试,发现无法将print-identity-token用于我的用户帐户。相反,我不得不create a new service account and activate it。然后在curl命令中,像下面的示例一样指定服务帐户:

curl -i https://[REGION]-[PROJECT_ID].cloudfunctions.net/[FUNCTION_NAME] -H "Authorization: bearer $(gcloud auth print-identity-token [SERVICE_ACCOUNT] )"

显然,Google Cloud SDK在版本254上的gcloud auth print-identity-token命令中存在问题,您也可以尝试使用以下命令将其降级:

gcloud components update --version 249.0.0
