我正在尝试启用HTTP基本身份验证来访问Intranet站点。
这是我正在使用的代码:
from bs4 import BeautifulSoup
import urllib.request, base64, urllib.error
request = urllib.request.Request(url)
string = '%s:%s' % ('username','password')
base64string = base64.standard_b64encode(string.encode('utf-8'))
request.add_header("Authorization", "Basic %s" % base64string)
try:
u = urllib.request.urlopen(request)
except urllib.error.HTTPError as e:
print(e)
print(e.headers)
soup = BeautifulSoup(u.read(), 'html.parser')
print(soup.prettify())
但是它不起作用,并且
401 Authorization required.
失败,我不知道为什么它不起作用。 最佳答案
给定here的解决方案无需任何修改即可工作。
from bs4 import BeautifulSoup
import urllib.request
# 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
u = opener.open(url)
soup = BeautifulSoup(u.read(), 'html.parser')
前面的代码也可以正常工作。您只需要解码utf-8编码的字符串,否则标头包含一个字节序列。
from bs4 import BeautifulSoup
import urllib.request, base64, urllib.error
request = urllib.request.Request(url)
string = '%s:%s' % ('username','password')
base64string = base64.standard_b64encode(string.encode('utf-8'))
request.add_header("Authorization", "Basic %s" % base64string.decode('utf-8'))
try:
u = urllib.request.urlopen(request)
except urllib.error.HTTPError as e:
print(e)
print(e.headers)
soup = BeautifulSoup(u.read(), 'html.parser')
print(soup.prettify())
