您是否尝试过使用请求库？我相信它提供了一个对urllib的抽象。

Have you tried using the requests library? I believe it provides an abstraction over urllib.

下面的解决方案应该为你工作，但它使用请求库而不是urllib（但请求> urllib反正！让我知道您是否喜欢继续使用urllib。

The following solution should work for you, but it uses the requests library instead of urllib (but requests > urllib anyway!). Let me know if you prefer to continue using urllib.

import os
import requests
def download(url, chunk_s=1024, fname=None):
    if not fname:
        fname = url.split('/')[-1]
    req = requests.get(url, stream=True)
    with open(fname, 'wb') as fh:
        for chunk in req.iter_content(chunk_size=chunk_s):
            if chunk:
                fh.write(chunk)
    return os.path.join(os.getcwd(), fname)
