我一直在玩漂亮的汤并解析网页几天。我一直在使用一行代码,这是我编写的所有脚本中的救星。代码行是:
r = requests.get('some_url', auth=('my_username', 'my_password')).
但是...
我想用(OPEN A URL WITH AUTHENTICATION)做同样的事情:
(1) sauce = urllib.request.urlopen(url).read() (1)
(2) soup = bs.BeautifulSoup(sauce,"html.parser") (2)
我无法打开网址并阅读需要身份验证的网页。我如何实现这样的目标:
(3) sauce = urllib.request.urlopen(url, auth=(username, password)).read() (3)
instead of (1)
看看官方文档中的如何使用urllib软件包获取Internet资源:
# create a password manager
password_mgr = urllib.request.HTTPPasswordMgrWithDefaultRealm()
# Add the username and password.
# If we knew the realm, we could use it instead of None.
top_level_url = "http://example.com/foo/"
password_mgr.add_password(None, top_level_url, username, password)
handler = urllib.request.HTTPBasicAuthHandler(password_mgr)
# create "opener" (OpenerDirector instance)
opener = urllib.request.build_opener(handler)
# use the opener to fetch a URL
opener.open(a_url)
# Install the opener.
# Now all calls to urllib.request.urlopen use our opener.
urllib.request.install_opener(opener)
