python - 在函数中调用时未定义 BeautifulSoup

Question

当我在函数内部调用 BeautifulSoup() 时，我的网络抓取工具抛出 NameError: name 'BeautifulSoup' is not Define ，但当我在函数外部调用它并将 Soup 传递为一个论点。

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))

但是当我将 BeautifulSoup 调用移到我的函数中时，我收到错误。

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

我猜你犯了一些BeautifulSoup的拼写错误，它区分大小写。如果没有，请在代码中使用请求:

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')
