使用 Python request 連接 Azure Blob Storage

輸入下方指令安裝套件

pip install requests

代碼如下：

import requests
from datetime import datetime, UTC
import hmac
import hashlib
import base64


def get_auth_signature(account_name: str, account_key: str, container_name: str, timestamp: str) -> str:
    """

    :param account_name: 帳號名稱
    :param account_key: 帳號金鑰

    :param timestamp: 時間戳記
    :return: 簽章字串
    """

    # 定義資源順序
    resource_path = f'/{account_name}/{container_name}'
