Google Cloud Platform：使用 api 列出可用项目

Question

我想gcloud projects list通过 api 调用 ( python)达到相同的效果。

但是，我在浏览文档时遇到的唯一问题就是这个。

此操作是否专门与资源管理器 API 相关联？

对其他项目的可见性会发生什么？如果 RM 绑定到一个项目，它如何查看（并因此列出）其他项目？

Answer 1

您只能列出您有权访问的项目。这意味着您无法看到所有项目，除非您有权访问它们。在下面的示例中，我展示了需要哪些范围。这也意味着您可以跨帐户列出项目。这允许您使用示例中指定的凭据查看您有权访问哪些项目。我展示了如何使用应用程序默认凭据 (ADC) 和服务帐户凭据（Json 文件格式）。

有关更多信息，您可以在此处阅读我关于项目的文章。

这些示例已经在 Windows 10 Professional 上使用 Python 3.6 进行了测试。这些示例将完全按照 CLI 显示项目列表。

使用 Python 客户端库的示例 1（服务发现方法）：

from googleapiclient import discovery
from oauth2client.client import GoogleCredentials
from google.oauth2 import service_account

# Example using the Python Client Library

# Documentation
# https://github.com/googleapis/google-api-python-client
# https://developers.google.com/resources/api-libraries/documentation/cloudresourcemanager/v2/python/latest/

# Library Installation
# pip install -U google-api-python-client
# pip install -U oauth2client

# Requires one of the following scopes
# https://www.googleapis.com/auth/cloud-platform
# https://www.googleapis.com/auth/cloud-platform.read-only
# https://www.googleapis.com/auth/cloudplatformprojects
# https://www.googleapis.com/auth/cloudplatformprojects.readonly

print('{:<20} {:<22} {:<21}'.format('PROJECT_ID', 'NAME', 'PROJECT_NUMBER'))

# Uncomment to use Application Default Credentials (ADC)
credentials = GoogleCredentials.get_application_default()

# Uncomment to use Service Account Credentials in Json format
# credentials = service_account.Credentials.from_service_account_file('service-account.json')

service = discovery.build('cloudresourcemanager', 'v1', credentials=credentials)

request = service.projects().list()

while request is not None:
    response = request.execute()

    for project in response.get('projects', []):
        print('{:<20} {:<22} {:<21}'.format(project['projectId'], project['name'], project['projectNumber']))

    request = service.projects().list_next(previous_request=request, previous_response=response)

示例 2 使用 Python Google Cloud Resource Manager API 客户端库：

from google.cloud import resource_manager

# Example using the Python Google Cloud Resource Manager API Client Library

# Documentation
# https://pypi.org/project/google-cloud-resource-manager/
# https://github.com/googleapis/google-cloud-python
# https://googleapis.github.io/google-cloud-python/latest/resource-manager/index.html
# https://googleapis.github.io/google-cloud-python/latest/resource-manager/client.html
# https://googleapis.github.io/google-cloud-python/latest/resource-manager/project.html

# Library Installation
# pip install -U google-cloud-resource-manager

# Requires one of the following scopes
# https://www.googleapis.com/auth/cloud-platform
# https://www.googleapis.com/auth/cloud-platform.read-only
# https://www.googleapis.com/auth/cloudplatformprojects
# https://www.googleapis.com/auth/cloudplatformprojects.readonly

print('{:<20} {:<22} {:<21}'.format('PROJECT_ID', 'NAME', 'PROJECT_NUMBER'))

# Uncomment to use Application Default Credentials (ADC)
client = resource_manager.Client()

# Uncomment to use Service Account Credentials in Json format
# client = resource_manager.Client.from_service_account_json('service-account.json')

for project in client.list_projects():
    print('{:<20} {:<22} {:<21}'.format(project.project_id, project.name, project.number))

Answer 2

在较新版本的 Python 客户端库中，ProjectsClient.search_projects具有与预发行版Client.list_projectsgcloud projects list类似的功能，而后者又与命令行类似。

最小样本

from google.cloud.resourcemanager import ProjectsClient

for project in ProjectsClient().search_projects():
    print(project.display_name)
