Question

当我在函数内部调用BeautifulSoup（）时，我的Web抓取工具会抛出NameError: name 'BeautifulSoup' is not defined，但当我在函数外部调用它并将Soup作为参数传递时，它会正常工作。

这是工作代码：

from teams.models import *
from bs4 import BeautifulSoup
from django.conf import settings
import requests, os, string

soup = BeautifulSoup(open(os.path.join(settings.BASE_DIR, 'revolver.html')), 'html.parser')

def scrapeTeamPage(soup):
    teamInfo = soup.find('div', 'profile_info')
...
print(scrapeTeamPage(soup))

但是当我在函数中移动BeautifulSoup调用时，我得到了错误。

from teams.models import *
from bs4 import BeautifulSoup
from django.conf import settings
import requests, os, string

def scrapeTeamPage(url):
    soup = BeautifulSoup(open(os.path.join(settings.BASE_DIR, url)), 'html.parser')
    teamInfo = soup.find('div', 'profile_info')

Answer 1

我猜您在执行BeautifulSoup的一些拼写错误，它区分大小写。如果没有，请在代码中使用以下请求：

from teams.models import *
from bs4 import BeautifulSoup
from django.conf import settings
import requests, os, string

def scrapeTeamPage(url):
    res = requests.get(url)
    soup = BeautifulSoup(res.content, 'html.parser')
    teamInfo = soup.find('div', 'profile_info')

Answer 2

先将 BeautifulSoup 导入到一个变量中，然后再使用。

    from bs4 import BeautifulSoup as yourVariable

在函数中调用时未定义BeautifulSoup
