HTTP 错误 403：使用 urllib 下载文件时被禁止

Question

我有这行代码：urllib.request.urlretrieve('http://lolupdater.com/downloads/LPB.exe', 'LPBtest.exe')，但是当我运行它时，它会抛出错误 urllib.error.HTTPError: HTTP Error 403: Forbidden。

Answer 1

这看起来是一个实际的 HTTP 403: Forbidden 错误。 Python urllib 在遇到 HTTP 状态代码时抛出异常（已记录 here). 403 in general means: "The server understood the request, but is refusing to fulfill it." You will need to add HTTP headers to identify yourself and avoid the 403 error, documentation on Python urllib headers。这是一个使用 urlopen:

的示例

import urllib.request
req = urllib.request.Request('http://lolupdater.com/downloads/LPB.exe', headers={'User-Agent': 'Mozilla/5.0'})
response = urllib.request.urlopen(req)

With Python 3 urllib.urlretrieve() is considered legacy. I would recommend Python Requests for this, here is a working example:

import requests

url = 'http://lolupdater.com/downloads/LPB.exe'
r = requests.get(url)
with open('LPBtest.exe', 'wb') as outfile:
    outfile.write(r.content)
