06 提取数据的json字符串

# 1.导入相关模块
import re
import requests
from bs4 import BeautifulSoup

# 2.发送请求，获取疫情首页内容
response = requests.get('https://ncov.dxy.cn/ncovh5/view/pneumonia')
home_page = response.content.decode()

# 3.使用BeautifulSoup提取疫情数据
soup = BeautifulSoup(home_page, 'lxml')
script = soup.find(id="getListByCountryTypeService2true")
# print(script)  # 这里直接写script就行，就能把内容全部打印出来

# 4.使用正则表达式，提取json字符串
json_str = re.findall(r'[.+]', script.string)[0]
print(json_str)
