bs4 和请求代理脚本错误

Question

我目前正在编写一个从 Supremenewyork.com 提取信息的脚本 我使用的这个代理脚本之前一直在“排序”，现在它根本不起作用，因为我在我的电脑上看到了这个叫做 urllib3 的东西，我认为它没用，所以我卸载了它，然后我尝试再次运行我的代理脚本，我得到一个关于 urllib3 的错误，所以我很快重新安装了 urllib3，但在那之后我的脚本再也没有工作过...... 这是我的脚本：

import requests
from bs4 import BeautifulSoup
UK_Proxy1 = input('UK http Proxy1: ')
UK_Proxy2 = input('UK http Proxy2: ')

proxies = {
 'http': 'http://' + UK_Proxy1 + '',
   'https': 'http://' + UK_Proxy2 + '',

}

categorys = ['jackets','shirts','tops_sweaters','sweatshirts','pants','shorts','t-shirts','hats','bags','accessories','shoes','skate']
catNumb = 0

for cat in categorys:
    catStr = str(categorys[catNumb])
    cUrl = 'http://www.supremenewyork.com/shop/all/' + catStr
    proxy_script = requests.get(cUrl, proxies=proxies).text
    bSoup = BeautifulSoup(proxy_script, 'lxml')
    print('\n*******************"'+ catStr.upper() + '"*******************\n')
catNumb += 1
for item in bSoup.find_all('div', class_='inner-article'):
    url = item.a['href']
    alt = item.find('img')['alt']
    req = requests.get('http://www.supremenewyork.com' + url)
    item_soup = BeautifulSoup(req.text, 'lxml')
    name = item_soup.find('h1', itemprop='name').text
    style = item_soup.find('p', itemprop='model').text
    print (alt + ' --- ' + name + ' --- ' + style)

当我运行此脚本并输入英国代理时，我收到此错误

在处理上述异常的过程中，又发生了一个异常：

During handling of the above exception, another exception occurred: (same error as above and continues for a bit)

我尝试了几种不同的代理，但都没有奏效 有人可以帮助我吗，我真的很感激它

这里是答案的基线， 它不起作用，因为没有连接到代理。

你所要做的就是为它提供一个工作代理和一个端口，如果你的计算机没有互联网连接，它会给你同样的错误，但因为你在 StackOverflow 我会假设你有那个。

urllib3.exceptions.MaxRetryError: HTTPConnectionPool(host='109.108.153.29\t', port=80): Max retries exceeded with url: http://www.supremenewyork.com/shop/all/jackets (Caused by ProxyError('Cannot connect to proxy.', NewConnectionError('<urllib3.connection.HTTPConnection object at 0x112d10eb8>: Failed to establish a new connection: [Errno 8] nodename nor servname provided, or not known',))) 以下是我们修复它的方法： 我们不使用有效的代理并为其提供端口， 您可以在此网站上获取代理列表并使用random.choice() 始终选择其他代理。http://www.gatherproxy.com/
