Python URL解析：从某个文件夹获取N个文件夹，后跟文件名

我有一个URL，它可以有任意数量的文件夹，并且以filename.extension结尾

例如：

https://cdn.example.com/user/image/upload/v87879798/images/profile/oaz4wkjkjsbzxa3xlkmu.jpg

在/V879798版本折叠后，我尝试获取所有内容，因此：

images/profile/oaz4wkjkjsbzxa3xlkmu.jpg

我已经尝试了以下几种方法，但没有任何效果，因为我知道我很可能需要一个正则表达式，但我对它们的了解还不允许我构造这样的方法。我尝试过的一些方法有：

import os
from urllib.parse import urlparse
# url https://cdn.example.com/user/image/upload/v87879798/images/profile/oaz4wkjkjsbzxa3xlkmu.jpg
parsed_url = urlparse(url)
# parsed_url.path /lang-code/image/upload/v1601568948/images/profile
path = os.path.dirname(parsed_url.path)
# file_name oaz4wkjkjsbzxa3xlkmu.jpg
file_name = os.path.basename()

但到目前为止，还没有任何有效的方法。任何帮助都将不胜感激

编辑： 对不起，我忘了提及我所说的N个文件夹的意思是，以下URL中的任何一个都是可能的：

https://cdn.example.com/user/image/upload/v87879798/images/profile/oaz4wkjkjsbzxa3xlkmu.jpg

https://cdn.example.com/user/image/upload/v87879798/images/oaz4wkjkjsbzxa3xlkmu.jpg

https://cdn.example.com/user/image/upload/v87879798/oaz4wkjkjsbzxa3xlkmu.jpg

使用正则表达式模式-->

r“v\d++\/（.+）$”

。假设随机数以

v开始

Ex:

import re
from urllib.parse import urlparse

ptrn = re.compile(r"v\d+\/(.+)$")
url = "https://cdn.example.com/user/image/upload/v87879798/images/profile/oaz4wkjkjsbzxa3xlkmu.jpg"
parsed_url = urlparse(url)
print(ptrn.search(parsed_url.path).group(1))

images/profile/oaz4wkjkjsbzxa3xlkmu.jpg

ptrn = re.compile(r"v\d+\/(.+)$")
urls = ["https://cdn.example.com/user/image/upload/v87879798/images/profile/oaz4wkjkjsbzxa3xlkmu.jpg", "https://cdn.example.com/user/image/upload/v87879798/images/profile/oaz4wkjkjsbzxa3xlkmu.jpg",
       "https://cdn.example.com/user/image/upload/v87879798/images/oaz4wkjkjsbzxa3xlkmu.jpg", "https://cdn.example.com/user/image/upload/v87879798/oaz4wkjkjsbzxa3xlkmu.jpg"]

for url in urls:
    parsed_url = urlparse(url)
    print(ptrn.search(parsed_url.path).group(1))

images/profile/oaz4wkjkjsbzxa3xlkmu.jpg
images/profile/oaz4wkjkjsbzxa3xlkmu.jpg
images/oaz4wkjkjsbzxa3xlkmu.jpg
oaz4wkjkjsbzxa3xlkmu.jpg

输出：

import re
from urllib.parse import urlparse

ptrn = re.compile(r"v\d+\/(.+)$")
url = "https://cdn.example.com/user/image/upload/v87879798/images/profile/oaz4wkjkjsbzxa3xlkmu.jpg"
parsed_url = urlparse(url)
print(ptrn.search(parsed_url.path).group(1))

ptrn = re.compile(r"v\d+\/(.+)$")
urls = ["https://cdn.example.com/user/image/upload/v87879798/images/profile/oaz4wkjkjsbzxa3xlkmu.jpg", "https://cdn.example.com/user/image/upload/v87879798/images/profile/oaz4wkjkjsbzxa3xlkmu.jpg",
       "https://cdn.example.com/user/image/upload/v87879798/images/oaz4wkjkjsbzxa3xlkmu.jpg", "https://cdn.example.com/user/image/upload/v87879798/oaz4wkjkjsbzxa3xlkmu.jpg"]

for url in urls:
    parsed_url = urlparse(url)
    print(ptrn.search(parsed_url.path).group(1))

images/profile/oaz4wkjkjsbzxa3xlkmu.jpg
images/profile/oaz4wkjkjsbzxa3xlkmu.jpg
images/oaz4wkjkjsbzxa3xlkmu.jpg
oaz4wkjkjsbzxa3xlkmu.jpg
