Python 中的网站名称提取

Question

我想从 url 中提取网站名称。例如https://plus.google.com/in/test.html 应该给出输出 - "plus google"

更多测试用例是 -

WWW.OH.MADISON.STORES.ADVANCEAUTOPARTS.COM/AUTO_PARTS_MADISON_OH_7402.HTML

输出：- OH MADISON 商店 ADVANCEAUTOPARTS

WWW.LQ.COM/LQ/PROPERTIES/PROPERTYPROFILE.DO?PROPID=6054

输出：- LQ

WWW.LOCATIONS.DENNYS.COM

输出：- LOCATIONS DENNYS

WV.WESTON.STORES.ADVANCEAUTOPARTS.COM

输出：- WV WESTON 商店 ADVANCEAUTOPARTS

WOODYANDERSONFORDFAYETTEVILLE.NET/

输出：- WOODYANDERSONFORFAYETTEVILLE

WILMINGTONMAYFAIRETOWNCENTER.HGI.COM

输出：- WILMINGTONMAYFAIRETOWNCENTER HGI

WHITEHOUSEBLACKMARKET.COM/

输出：- WHITEHOUSEBLACKMARKET

WINGATEHOTELS.COM

输出：- WINGATEHOTELS

string = str(input("Enter the url "))
new_list = list(string)
count=0
flag=0

if 'w' in new_list:
    index1 = new_list.index('w')
    new_list.pop(index1)
    count += 1
if 'w' in new_list:
    index2 = new_list.index('w')
    if index2 != -1 and index2 == index1:
        new_list.pop(index2)
        count += 1
if 'w' in new_list:
    index3= new_list.index('w')
    if index3!= -1 and index3== index2 and new_list[index3+1]=='.':
        new_list.pop(index3)
        count+=1      
        flag = 1
if flag == 0:
    start = string.find('/')
    start += 2
    end = string.rfind('.')

    new_string=string[start:end]
    print(new_string)
elif flag == 1:
    start = string.find('.')
    start = start + 1
    end = string.rfind('.')

    new_string=string[start:end]
    print(new_string)

以上适用于一些测试用例，但不是全部。请帮助我。

谢谢

Answer 1

这是您可以建立的基础；使用 urllib.parse.urlparse:

from urllib.parse import urlparse

tests = ('https://plus.google.com/in/test.html',
         ('WWW.OH.MADISON.STORES.ADVANCEAUTOPARTS.COM/'
          'AUTO_PARTS_MADISON_OH_7402.HTML'),
         'WWW.LQ.COM/LQ/PROPERTIES/PROPERTYPROFILE.DO?PROPID=6054')

def extract(url):
    # urlparse will not work without a 'scheme'
    if not url.startswith('http'):
        url = 'http://' + url
    parsed = urlparse(url).netloc
    split = parsed.split('.')[:-1] # get rid of TLD
    if split[0].lower() == 'www':
        split = split[1:]
    ret = ' '.join(split)
    return ret

for url in tests:
    print(extract(url))

该函数将 url 从双斜线剥离为单斜线：剩下的是 'clean up'

def stripURL( url, TwoSlashes, OneSlash ):
    try:
        start = url.index(TwoSlashes) + len(TwoSlashes)
        end = url.index( OneSlash, start )
        return url[start:end]
    except ValueError:
        return ""
url= raw_input("URL : ")
if "www." in url:url=url.replace("www.","")
Strip = stripURL( url, "//", "/" )
# Strips anything after the last period found
Stripped = Strip[:Strip.rfind(".")]
# get rid of the any periods used in the name 
Stripped = Stripped.replace("."," ")
print Stripped
