解析div中的json对象，同时使用beautifulsoup-python进行抓取

import pip
import requests
import json 
from bs4 import BeautifulSoup
print ('hi')
page = requests.get('https://www.nseindia.com/live_market/dynaContent/live_watch/get_quote/GetQuote.jsp?symbol=NBCC&illiquid=0&smeFlag=0&itpFlag=0')
soup = BeautifulSoup(page.text, 'html.parser')
json_d = soup.find(id='responseDiv')
print ('bye')

import bs4
import json
r= '''

html = bs4.BeautifulSoup(r)
soup = html.find('div', {'id':'responseDiv'}).text
data = json.loads(soup)
last_price = data['data'][0]['lastPrice']

编辑：

json_d = soup.find(id='responseDiv')

尝试更改为

json_d = soup.find(‘div’, {‘id’:'responseDiv'})

然后你应该能够做

data = json.loads(json_d)
last_price = data['data'][0]['lastPrice']

看看这是否有帮助。我目前在周二之前都不在电脑上，所以在iPhone上打这个，所以无法测试/玩它。

另一件事是，该网站可能需要在加载后被读入。在这种情况下，我认为您需要查看selenium包或html请求包。

再说一次，我要到星期二才能回家拿笔记本电脑。
