问题描述
在我的Django应用中,我需要在 request.META.get('HTTP_REFERER')
的引荐来源网址中获取主机名及其协议,以便从URL像这样:
In my Django app, I need to get the host name from the referrer in request.META.get('HTTP_REFERER')
along with its protocol so that from URLs like:
- https://docs.google.com/spreadsheet/ccc?key=blah-blah-blah-blah#gid=1
- https://stackoverflow.com/questions/1234567/blah-blah-blah-blah
- http://www.example.com
- https://www.other-domain.com/whatever/blah/blah/?v1=0&v2=blah+blah ...
- https://docs.google.com/spreadsheet/ccc?key=blah-blah-blah-blah#gid=1
- https://stackoverflow.com/questions/1234567/blah-blah-blah-blah
- http://www.example.com
- https://www.other-domain.com/whatever/blah/blah/?v1=0&v2=blah+blah ...
我应该得到:
- https://docs.google.com/
- https://stackoverflow.com/
- http ://www.example.com
- https:/ /www.other-domain.com/
- https://docs.google.com/
- https://stackoverflow.com/
- http://www.example.com
- https://www.other-domain.com/
我查看了其他相关问题并发现了有关urlparse的信息,
I looked over other related questions and found about urlparse, but that didn't do the trick since
>>> urlparse(request.META.get('HTTP_REFERER')).hostname
'docs.google.com'
推荐答案
您应该可以使用 urlparse
(文档: python2 , python3 ):
You should be able to do it with urlparse
(docs: python2, python3):
from urllib.parse import urlparse
# from urlparse import urlparse # Python 2
parsed_uri = urlparse('http://stackoverflow.com/questions/1234567/blah-blah-blah-blah' )
result = '{uri.scheme}://{uri.netloc}/'.format(uri=parsed_uri)
print(result)
# gives
'http://stackoverflow.com/'
