推荐答案
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(记录在 此处).403
一般的意思是:服务器理解请求,但拒绝满足它."您将需要添加 HTTP 标头以识别您自己并避免 403
错误,关于 Python urllib 标头.下面是一个使用 urlopen
的例子:
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 被视为遗产.我会为此推荐 Python 请求,这是一个工作示例:
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)
