用Python 采集为什么获取不到数据呢，谢谢?

Question

import re
import requests

headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36',
    'Referer': 'http://cq.jiaoyubao.cn/',
    'Host': 'cq.jiaoyubao.cn',
    'Upgrade-Insecure-Requests': '1',
}

r = requests.get('http://cq.jiaoyubao.cn/cn/xiaoxue/', headers=headers)

print(r.status_code)
print(r.text)

以上运行结果为:

</script></div><script src="http://chat.jiaoyubao.cn/js/mchat.js"></script><script src="http://chat.jiaoyubao.cn/js/online.js?style=1"></script><script type="text/javascript" src="http://static.jiaoyubao.cn/js/share4.js"></script><script src="/bottom/js/bottom.js"></script><script type="text/javascript" src="http://static.jiaoyubao.cn/js/p.js"></script></body></html>

并没有获得有用的内容，代码初步看没什么问题，请问如何解决，谢谢

pip install bs4
pip install lxml

import re
import requests
from bs4 import BeautifulSoup
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36',
    'Referer': 'http://cq.jiaoyubao.cn/',
    'Host': 'cq.jiaoyubao.cn',
    'Upgrade-Insecure-Requests': '1',
}

r = requests.get('http://cq.jiaoyubao.cn/cn/xiaoxue/', headers=headers)

soup = BeautifulSoup(r.content, 'lxml')
print(soup.prettify())
