大神们，帮忙看一下，为什么没有打印出东西？

Question

import requests
from lxml import etree

headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36"}
url = "https://www.qiushibaike.com/text/"
response = requests.get(url,headers = headers)
selector = etree.HTML(response.text)
result = selector.xpath('//*[@id="qiushi_tag_121225349"]/a[1]/div/span/text()')
print(result)

Answer 1

调试看下
response = requests.get(url,headers = headers)
这里如果有结果，说明抓取是正确的，否则是错误的，如果错误，抓包看下请求、url

如果html获取正确，检查result = selector.xpath('//*[@id="qiushi_tag_121225349"]/a[1]/div/span/text()')
一层一层来，首先看[@id="qiushi_tag_121225349"] 这个有没有
然后看a有没有，div，span...
