python - 用python分割url

Question

我有这个网址:

/drive/rayon.productlist.seomenulevel/fh_refpath$003dfacet_1$0026fh_refview$003dlister$0026fh_view_size$003d100$0026fh_reffacet$003dcategories$0026auchan_page_type$003dcatalogue$0026fh_location$003d$00252f$00252f52$00252ffr_FR$00252fdrive_id$00253d993$00252fcategories$00253c$00257b52_3686967$00257d$00252fcategories$00253c$00257b52_3686967_3686326$00257d$00252fcategories$00253c$00257b52_3686967_3686326_3700610$00257d$00252fcategories$00253c$00257b52_3686967_3686326_3700610_3700620$00257d/Capsules$0020$002843$0029/3700620?t:ac=3686967/3700610

我想要最后 3 个数字:item[0] = 3700620、item[1]=3686967 和 item[2] = 3700610

我试过了

one =   url.split('/')[-1]
two =   url.split('/')[-2]

第一个的结果是 3700610"

第二个 3700620?t:ac=3686967

Answer 1

非正则表达式方法将涉及使用 urlparse和一点 split :

>>> import urlparse
>>> parsed_url = urlparse.urlparse(url) 
>>> number1 = parsed_url.path.split("/")[-1]
>>> number2, number3 = urlparse.parse_qs(parsed_url.query)["t:ac"][0].split("/")
>>> number1, number2, number3
('3700620', '3686967', '3700610')

正则表达式方法:

>>> import re
>>> re.search(r"/(\d+)\?t:ac=(\d+)/(\d+)$", url).groups()
('3700620', '3686967', '3700610')

其中 (\d+) 是 saving/capturing groups匹配一个或多个数字，\? 将匹配文字问号(我们需要将其转义，因为它具有特殊含义)，$ 将匹配字符串。

您也可以name the groups并生成字典:

>>> re.search(r"/(?P<number1>\d+)\?t:ac=(?P<number2>\d+)/(?P<number3>\d+)", url).groupdict()
{'number2': '3686967', 'number3': '3700610', 'number1': '3700620'}
