推荐答案
这似乎是实际的HTTP 403:禁止
错误。 Python urllib
遇到HTTP状态代码时会引发异常(记录为此处)。 403
的一般含义是:服务器理解了该请求,但拒绝执行该请求。您将需要添加HTTP标头以标识自己,并避免 403
错误,有关 Python urllib标头。以下是使用 urlopen
的示例:
That looks to be an actual HTTP 403: Forbidden
error. Python urllib
throws the exception when it encounters an HTTP status code (documented 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. Here is an example using urlopen
:
import urllib.request
req = urllib.request.Request('http://lolupdater.com/downloads/LPB.exe', headers={'User-Agent': 'Mozilla/5.0'})
response = urllib.request.urlopen(req)
使用Python 3 urllib.urlretrieve()
是考虑为旧版。为此,我建议 Python请求,这是一个有效的示例:
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)
