要导入或导出备份数据存储/云端文件库而不使用gcloud，您可以使用Google Cloud Storage API进行操作。下面是一个示例，展示如何使用Google Cloud Storage API来导入和导出备份数据存储/云端文件库。

导入备份数据存储/云端文件库：

import requests

def import_data(project_id, bucket_name, file_name, datastore_kind):
    url = f"https://firestore.googleapis.com/v1/projects/{project_id}/databases/(default):import"
    headers = {"Content-Type": "application/json"}
    data = {
        "inputUriPrefix": f"gs://{bucket_name}/{file_name}",
        "collectionId": datastore_kind
    }
    response = requests.post(url, headers=headers, json=data)
    if response.status_code == 200:
        print("Import operation started successfully.")
    else:
        print(f"Failed to start import operation. Error: {response.text}")

# 使用示例
import_data("your-project-id", "your-bucket-name", "your-file-name", "your-datastore-kind")

导出备份数据存储/云端文件库：

import requests

def export_data(project_id, bucket_name, file_name, datastore_kind):
    url = f"https://firestore.googleapis.com/v1/projects/{project_id}/databases/(default):export"
    headers = {"Content-Type": "application/json"}
    data = {
        "outputUriPrefix": f"gs://{bucket_name}/{file_name}",
        "collectionIds": [datastore_kind]
    }
    response = requests.post(url, headers=headers, json=data)
    if response.status_code == 200:
        print("Export operation started successfully.")
    else:
        print(f"Failed to start export operation. Error: {response.text}")

# 使用示例
export_data("your-project-id", "your-bucket-name", "your-file-name", "your-datastore-kind")

请确保您已安装了 requests 库，并将上述代码中的参数替换为适合您的项目和设置的值。此外，您还需要设置适当的身份验证和访问权限，以便您的应用程序可以访问Google Cloud Storage和备份数据存储/云端文件库。
