我需要从html中提取代理数据 最小的例子：
from bs4 import BeautifulSoup
import requests
url="http://www.gatherproxy.com/proxylist/country/?c=Germany"
r = requests.get(url,timeout=15)
sp=BeautifulSoup(r.content,'html.parser')
tab=sp.find("table",id="tblproxy")
rows=tab.find_all('tr')
print(rows)
print命令应该显示表的所有内容... 但是，似乎bs只解析了前2行，而完全忽略了其余的行...
有什么想法吗？
答案 0 :(得分：1)
是b'coz，其余行由javascript填充。您可以使用Requests-html或硒来获取此数据。另外，您也可以从<script>标记中将其删除。
from bs4 import BeautifulSoup
from requests_html import HTMLSession
session = HTMLSession()
r = session.get('http://www.gatherproxy.com/proxylist/country/?c=Germany')
r.html.render()
sp=BeautifulSoup(r.html.html,'html.parser')
tab=sp.find("table",id="tblproxy")
rows=tab.find_all('tr')
print(rows[2:]) #only from third row
输出
