import urllib.request
 
def download_data(url, local_filename):
    try:
        # 打开 URL 并获取文件对象
        with urllib.request.urlopen(url) as response:
            # 读取文件内容
            data = response.read()
 
            # 将数据写入本地文件
            with open(local_filename, 'wb') as local_file:
                local_file.write(data)
 
        print(f"Downloaded data and saved as: {local_filename}")
    except Exception as e:
        print(f"Error downloading data: {e}")
 
 
data_url = "https://t7.baidu.com/it/u=1595072465,3644073269&fm=193&f=GIF"
# 本地保存路径
local_path = "/temp/downloaded_image.jpg"
 
# 调用下载函数
download_data(data_url, local_path)
