Question

我有一个名为href_w的列表，下载了一堆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):

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

我能做些什么来做对吗？

Answer 1

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。如果你使用curl或wget，你可能会得到相同的响应。

无论如何，你应该总是尝试使用curl或wget来调试这些问题。

Answer 2

我使用了这个脚本。它获取文件的url，读取并保存到文件中。这是下载mp3的示例。

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()

Mp3下载urllib.request.urlopen（）超时
