[极客大挑战 2019]Http
本文共 1182 字，大约阅读时间需要 3 分钟。
首先查看源码，发现了Scret.php
说我们不是从https://www.Sycsecret.com访问的，那就使用python修改请求头： import requestsurl = 'http://node3.buuoj.cn:25765/Secret.php'headers={"Referer":"https://www.Sycsecret.com","Origin":"https://www.Sycsecret.com"}r = requests.get(url,headers=headers)with open("1.html",'w')as f: f.write(r.text) 运行一下，python自动将html代码写入到1.html中，打开1.html：
这里提示我们需要使用”Syclover”浏览器，这里直接修改UA头即可，加一句headers['User-Agent'] = "Syclover"
import requestsurl = 'http://node3.buuoj.cn:25765/Secret.php'headers={"Referer":"https://www.Sycsecret.com","Origin":"https://www.Sycsecret.com"}headers['User-Agent'] = "Syclover"r = requests.get(url,headers=headers)with open("1.html",'w')as f: f.write(r.text) 
headers['X-Forwarded-For'] = '127.0.0.1' import requestsurl = 'http://node3.buuoj.cn:25765/Secret.php'headers={"Referer":"https://www.Sycsecret.com","Origin":"https://www.Sycsecret.com"}headers['User-Agent'] = "Syclover"headers['X-Forwarded-For'] = '127.0.0.1'r = requests.get(url,headers=headers)with open("1.html",'w')as f: f.write(r.text)

不会用python用BP也可以做，附上大佬博客：
