使用特定 URL 和脚本构建代理旋转器

Question

我正在努力使用为不同 url 构建的现有代码来构建代理旋转器。

下面的代码示例中提供了我想要的网址。当代理类型为 "HTTPS" 时，我试图让提供的脚本调用所需的 URL 并获取 ALL 'IP:PORT'（当前脚本限制为 10 个）。
xpath或者bs4都可以。不过我对bs4比较熟悉

我理解其中的逻辑，但我不知道如何构建它。首先，我尝试剥离字符串并尝试调用特定的 td 元素，但它不起作用。

#URLs I want 
url_list = ['http://spys.one/free-proxy-list/US/','http://spys.one/free-proxy-list/US/1/']

#code I have 
 from lxml.html import fromstring
 import requests
 from itertools import cycle
 import traceback

 def get_proxies():
 url = 'https://free-proxy-list.net/'
 response = requests.get(url)
 parser = fromstring(response.text)
 proxies = set()
 for i in parser.xpath('//tbody/tr')[:10]:
     if i.xpath('.//td[7][contains(text(),"yes")]'):
        proxy = ":".join([i.xpath('.//td[1]/text()')[0], i.xpath('.//td[2]/text()')[0]])
        proxies.add(proxy)
return proxies

proxies = get_proxies()
proxy_pool = cycle(proxies)
proxy = next(proxy_pool)
response = requests.get(url,proxies={"http": proxy, "https": proxy})

我希望了解所提供的代码是如何针对 2 个所需的 URL 构建的，return 所有 IP:PORT 代理类型为 HTTPS 时的数字

一种方法是在循环中发出特定于端口的 POST 请求。您可以修改以添加到一个最终列表中。端点已经是特定于 https 的。

import requests
from bs4 import BeautifulSoup as bs

def get_proxies(number, port, p):
    r = requests.post('http://spys.one/en/https-ssl-proxy/', data = {'xpp': 5, 'xf4': number})
    proxies = [':'.join([str(i),port]) for i in p.findall(r.text)]
    return proxies

ports = ['3128', '8080', '80']
p = re.compile(r'spy14>(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})<script')
proxies = []

for number, port in enumerate(ports,1):
    proxies+=get_proxies(number, port, p)

print(proxies)

示例结果：

针对特定国家/地区：

import requests
from bs4 import BeautifulSoup as bs

def get_proxies(number, port, p, country):
    r = requests.post('http://spys.one/en/https-ssl-proxy/',  data = {'xpp': 5, 'xf4': number})
    soup = bs(r.content, 'lxml')
    proxies = [':'.join([p.findall(i.text)[0], port]) for i in soup.select('table table tr:has(.spy14:contains("' + country + '")) td:has(script) .spy14')]
    return proxies

ports = ['3128', '8080', '80']
p = re.compile(r'(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})document')
proxies = []

for number, port in enumerate(ports,1):
    proxies+=get_proxies(number, port, p, 'United States')

print(proxies)

你说的那个已经写好了我就参考我原来的回答：

from bs4 import BeautifulSoup as bs
import requests

def get_proxies(): 
    r = requests.get('https://free-proxy-list.net/')
    soup = bs(r.content, 'lxml')
    proxies = {tr.td.text + ':' + tr.td.next_sibling.text for tr in soup.select('tr:has(.hx:contains(yes))')} 
    return proxies 

get_proxies()
