Python - 使用BeautifulSoup和Urllib进行网络爬虫

Question

我正在尝试阅读网站，但不幸的是出现了一些问题。

import bs4 as bs
import urllib.request

sauce = urllib.request.urlopen('https://csgoempire.com/withdraw').read()
soup = bs.BeautifulSoup(sauce,'lxml')

print(soup.find_all('p'))

错误：

Traceback (most recent call last):
  File "F:/Informatika/Python3X/GamblinSitesBot/GamblingSitesBot.py", line 4, in <module>
    sauce = urllib.request.urlopen('https://csgoempire.com/').read()
  File "c:\users\edgaras\appdata\local\programs\python\python36\Lib\urllib\request.py", line 223, in urlopen
    return opener.open(url, data, timeout)

    response = meth(req, response)

    return self._call_chain(*args)

    result = func(*args)
  File "c:\users\edgaras\appdata\local\programs\python\python36\Lib\urllib\request.py", line 650, in http_error_default
    raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 403: Forbidden

Process finished with exit code 1

此外，这段代码还可以与其他网站（如google.com）配合使用。

我认为这不是完整的堆栈跟踪？如果是，请提供完整的错误信息。 - DeepSpace

似乎该URL需要身份验证。会抛出403错误。 - sytech

你有代理吗？ - Hari

可能是Python 3网络爬虫中的HTTP错误403的重复问题。 - Abhishek Keshri

您可以使用 request 库来实现相同的功能。这个方法很好用。

import bs4 as bs
import requests

sauce = requests.get('https://csgoempire.com/withdraw')
soup = bs.BeautifulSoup(sauce.content,'html.parser')
print(soup.find_all('p'))
