如何使用特定名称保存下载的图像？

Question

我有这段代码循环遍历 df（excel 文件）并为要保存的图像创建 link。该代码可用于为图像创建 links，但我无法使用在我的 df、

中找到的 links 名称保存图像

例如：

/images/S/aplus-media/vc/9c4fd284-2d51-47d8-8275-9977cc5f9771.jpg

lst = just_img_col.values.tolist()

var = 'https://m.media-amazon.com/'

for val in lst:
    for ele in val:
      if len(str(ele)) > 10:
        image_url = var + str(ele)
        print(image_url)
        r = requests.get(image_url, stream=True)
        filename = str(ele)
        print(filename)

 if r.status_code == 200:
    r.raw.decode_content = True

# Open a local file with wb ( write binary ) permission.
with open(filename, 'wb') as f:
    shutil.copyfileobj(r.raw, f)

print('Image sucessfully Downloaded: ', filename)
else:
   print('Image Couldn\'t be retreived')

有什么我应该添加到我的代码中，以便我可以用这种格式的名称保存图像： /images/S/aplus-media/vc/9c4fd284-2d51-47d8-8275-9977cc5f9771.jpg?

links 的一些示例：

确保 var 和 ele 具有以下结构。看来你在搞乱正斜杠 /。在 GET 请求之前尝试 printing image_url。

import os
import requests


var = 'https://m.media-amazon.com/'
lst = [['/images/S/aplus-media/vc/9c4fd284-2d51-47d8-8275-9977cc5f9771.jpg']]

for val in lst:
    for ele in val:
        if len(str(ele)) > 10:
            image_url = os.path.join(var[:-1], str(ele)[1:])
            print(image_url)
            r = requests.get(image_url)
            filename = str(ele).replace('/', '_')
            

            if r.status_code == 200:
                # r.raw.decode_content = True
                # Open a local file with wb ( write binary ) permission.
                with open(filename, 'wb') as f:
                    f.write(r.content)

                print('Image sucessfully Downloaded: ', filename)
            else:
                print('Image Couldn\'t be retreived')
