如何使用Google Cloud Function为云SQL实例的授权网络添加ip？

from google.cloud import sql_v1beta4
from google.auth import compute_engine

def add_ip_to_sql(event, context):
    # 设置云SQL实例的信息
    project_id = 'YOUR_PROJECT_ID'
    instance_id = 'YOUR_SQL_INSTANCE_ID'
    authorized_networks = ['IP1', 'IP2', 'IP3']  # 要添加的IP列表

    # 使用compute_engine身份验证凭据
    credentials = compute_engine.Credentials()
    sql_admin_client = sql_v1beta4.CloudSqlAdminClient(credentials=credentials)

    # 获取现有的授权网络配置
    instance = sql_admin_client.instances.get(project=project_id, instance=instance_id)
    current_networks = instance.settings.ip_configuration.authorized_networks

    # 将新的IP添加到授权网络中
    new_networks = current_networks + authorized_networks

    # 更新云SQL实例的授权网络配置
    instance.settings.ip_configuration.authorized_networks = new_networks
    update_request = sql_admin_client.instances.patch(project=project_id, instance=instance_id, body=instance)
    update_request.result()

    print('IPs added to authorized networks:', authorized_networks)
