【问题描述】：

我有一个名为 href_w 的列表，其中包含一堆要下载的 mp3 链接，但是当我执行这段代码时，它给了我一个错误：

# Download file
print(color.BLUE + "\n[*] Downloading requested mp3(s) ..." + color.END)
for link in href_w:
    url = "http://www.mp3c.cc"+link.replace('track','files')
    print("[*] GET "+url)
    req = Request(url, headers={'User-Agent': 'Mozilla/5.0'})
    response = urlopen(req)
    html = response.read()

错误日志如下所示：

[*] Downloading requested mp3(s) ...
[*] GET http://www.mp3c.cc/files/88144527_288384031/
Traceback (most recent call last):

    response = urlopen(req)

    return opener.open(url, data, timeout)
  File "/usr/lib/python3.4/urllib/request.py", line 461, in open
    response = meth(req, response)
  File "/usr/lib/python3.4/urllib/request.py", line 571, in http_response
    'http', request, response, code, msg, hdrs)
  File "/usr/lib/python3.4/urllib/request.py", line 493, in error
    result = self._call_chain(*args)
  File "/usr/lib/python3.4/urllib/request.py", line 433, in _call_chain
    result = func(*args)
  File "/usr/lib/python3.4/urllib/request.py", line 676, in http_error_302
    return self.parent.open(new, timeout=req.timeout)
  File "/usr/lib/python3.4/urllib/request.py", line 461, in open
    response = meth(req, response)
  File "/usr/lib/python3.4/urllib/request.py", line 571, in http_response

    raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 502: Bad Gateway

我该怎么做才能做到正确？

【问题讨论】：

标签： python python-3.x urllib urlopen

【解决方案1】：

我使用了这个脚本。它需要文件的url，读取它并将其保存到文件中。这是下载的 mp3 示例。

import urllib

url = 'http://www.drowtales.com/download/Path%20to%20Power.mp3'

data = urllib.request.urlopen(url)

f = open('Path to Power.mp3','wb')
f.write(data.read())
f.close()

【解决方案2】：

如果您从 Web 服务器收到 502 响应，通常意味着他们的后端已关闭。如果您使用 curl 或 wget，您可能会得到相同的响应。

无论如何，您应该始终尝试 curl 或 wget 以调试此类问题。
