google-cloud-resource-manage list projects 403 调用者没有权限

Question

我创建了一个 GCP 服务帐户并分配了列出组织内项目所需的权限。当我使用gcloud cli 时，一切正常：

gcloud auth activate-service-account --key-file=./key.json
gcloud projects list

# -> List of all projects

但是，当我尝试使用 Python Client for Google Cloud Resource Manager 进行“相同”操作时，我收到了 403 The caller does not have permission 错误消息。

# pip install google-cloud-resource-manager==1.4.1
from google.oauth2 import service_account
from google.cloud import resourcemanager_v3

# Load gcp credentials
credentials = service_account.Credentials.from_service_account_file('./key.json')

# Create resourcemanager_v3 ProjectsClient
resourcemanager_v3_projects_client = resourcemanager_v3.ProjectsClient(credentials=credentials)

# Initialize request argument(s)
list_projects_request = resourcemanager_v3.ListProjectsRequest(show_deleted=False, parent='')

# Make the request
page_result = resourcemanager_v3_projects_client.list_projects(request=list_projects_request)


# -> Error...
# -> grpc_helpers.py", line 68, in error_remapped_callable
# -> raise exceptions.from_grpc_error(exc) from exc
# -> google.api_core.exceptions.PermissionDenied: 403 The caller does not have permission

Python Client for Google Cloud Resource Manager 是否需要gcloud cli 以外的其他权限，还是我错过了 Python 代码中的某些内容？

Answer 1

好像我错过了parentparameter...
以下片段应列出特定文件夹或组织的项目。

# pip install google-cloud-resource-manager==1.4.1
from google.oauth2 import service_account
from google.cloud import resourcemanager_v3

# Load gcp credentials
credentials = service_account.Credentials.from_service_account_file('./key.json')

# Create resourcemanager_v3 ProjectsClient
resourcemanager_v3_projects_client = resourcemanager_v3.ProjectsClient(credentials=credentials)

# Initialize request argument(s)
list_projects_request = resourcemanager_v3.ListProjectsRequest(show_deleted=False, parent='folders/%folder-id%') # for organization: 'organizations/%organization-id%'

# Make the request
page_result = resourcemanager_v3_projects_client.list_projects(request=list_projects_request)

# Handle the response
for response in page_result:
    print(response)
