如何使用Google Cloud Functions官方Python客户端获取指定项目云函数列表

• 首先安装官方推荐的依赖库：pip install google-cloud-functions
• 提前完成GCP身份鉴权配置：可通过设置环境变量GOOGLE_APPLICATION_CREDENTIALS指向你的服务账号JSON密钥文件，若代码运行在已绑定服务账号的GCP环境（如Cloud Shell、GCE、GKE等）中可省略该步骤

适合普通同步业务场景，直接调用即可返回指定项目下的所有云函数：

from google.cloud.functions_v1.services.cloud_functions_service import CloudFunctionsServiceClient

def list_gcp_functions(project_id: str, location: str = "-") -> list:
    """
    获取指定GCP项目下的云函数列表
    :param project_id: GCP项目ID
    :param location: 区域，传入"-"代表查询所有区域的函数
    """
    client = CloudFunctionsServiceClient()
    parent = f"projects/{project_id}/locations/{location}"
    
    functions = []
    # 处理分页返回结果
    for page in client.list_functions(parent=parent).pages:
        functions.extend(page.functions)
    
    return functions

# 调用示例
if __name__ == "__main__":
    project_id = "替换为你的GCP项目ID"
    all_functions = list_gcp_functions(project_id)
    for func in all_functions:
        print(f"函数名称：{func.name}，运行时：{func.runtime}，触发方式：{'HTTPS触发' if func.https_trigger is not None else '其他触发'}")

适合异步IO业务场景，调用逻辑和同步端基本一致：

import asyncio
from google.cloud.functions_v1.services.cloud_functions_service import CloudFunctionsServiceAsyncClient

async def list_gcp_functions_async(project_id: str, location: str = "-") -> list:
    client = CloudFunctionsServiceAsyncClient()
    parent = f"projects/{project_id}/locations/{location}"
    
    functions = []
    async for page in client.list_functions(parent=parent).pages:
        functions.extend(page.functions)
    
    return functions

# 调用示例
if __name__ == "__main__":
    project_id = "替换为你的GCP项目ID"
    all_functions = asyncio.run(list_gcp_functions_async(project_id))
    for func in all_functions:
        print(f"函数名称：{func.name}，运行时：{func.runtime}")

• 上述示例使用的是v1版本接口，默认返回1代云函数，如果需要获取2代云函数，可将导入路径替换为google.cloud.functions_v2.services.cloud_functions_service.CloudFunctionsServiceClient，调用逻辑完全不变
• 返回的函数实例包含全量配置字段，可按需提取状态、内存配置、触发事件、入口函数等信息
• 若仅需要查询单个区域的函数，将location参数替换为对应区域ID（如us-central1）即可
