如何使用 BeautifulSoup 在 Python 中找到课程文本“美国纽约市”？
尝试复制视频进行练习，但不再有效。
尝试在官方文档中找到一些内容，但没有成功。或者我的 get_html_content 函数无法正常工作，Google 只是阻止我，从而返回一个空的 list / None ？
这是我当前的代码：
from django.shortcuts import render
import requests
def get_html_content(city):
USER_AGENT = "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.157 Safari/537.36"
LANGUAGE = "en-US,en;q=0.5"
session = requests.Session()
session.headers['User-Agent'] = USER_AGENT
session.headers['Accept-Language'] = LANGUAGE
session.headers['Content-Language'] = LANGUAGE
city.replace(" ", "+")
html_content = session.get(f"https://www.google.com/search?q=weather+in+{city}").text
return html_content
def home(request):
result = None
if 'city' in request.GET:
city = request.GET.get('city')
html_content = get_html_content(city)
from bs4 import BeautifulSoup
soup = BeautifulSoup(html_content, 'html.parser')
soup.find_all('div', attrs={'class': 'wob_loc q8U8x'})
**OR**
soup.find_all('div', attrs={'id': 'wob_loc'})
--> 都返回空列表（= .find 方法返回 None）
Google 页面的布局可能同时发生了变化，因此要获取有关天气的数据，您必须更改代码。例如：
import requests from bs4 import BeautifulSoup params = {'q':'weather in New York City, New York, USA', 'hl': 'en'} headers = {'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:108.0) Gecko/20100101 Firefox/108.0'} cookies = {'CONSENT':"YES+cb.20220419-08-p0.cs+FX+111"} url = 'https://www.google.com/search' soup = BeautifulSoup(requests.get(url, params=params, headers=headers, cookies=cookies).content, 'html.parser') for t in soup.select('#wob_dp [aria-label]'): how = t.find_next('img')['alt'] temp = t.find_next('span').get_text(strip=True) print('{:打印：
