代码能运行,但是没有输出结果,哪里出问题了呢
```python
# -*- coding: utf-8 -*-
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/81.0.4044.138 Safari/537.36"
}
respone=requests.get("https://www.mfa.gov.cn/irs-c-web/search.shtml?code=17e50b77dab&dataTypeId=15&searchBy=title&searchWord=%E6%AC%A2%E4%B9%90%E6%98%A5%E8%8A%82")
html=respone.text
soup=BeautifulSoup(html,"html.parser")
all_times=soup.findAll("span",attrs={"class":"sourceTime"})
for time in all_times:
print(time.string)
```
如果你的程序正确,可能是你的编译器问题,因为编译器经常有这个bug。还有你仔细检查检查程序,因为虽然运行了,但不代表就能输出你想要的结果
网页是动态的,requests获取不到数据
通过api接口
import requests
import pandas as pd
import json
