Challenges Emdee five for life-easy

思路

入门题目。先get数据，然后POST提交MD5数值,即可获得flag

附上自己写的代码

#!/usr/bin/python3
import requests
import hashlib
from  lxml import etree

url = "http://159.65.51.138:30832/"
req = requests.session()
response = req.get(url).content.decode('utf-8')

html=etree.HTML(response,etree.HTMLParser())
result=html.xpath('//h3[@align="center"]/text()')[0]

m = hashlib.md5().update(result.encode("utf-8"))
md5 = m.hexdigest()

data = {'hash':md5}
flag = req.post(url=url,data=data)
print(flag.content.decode('utf-8'))  #HTB{N1c3_ScrIpt1nG_B0i!}
