请求接口带有加密参数：

全局搜索Sign,找到参数生成位置

一目了然，知道参数是怎么构造生成的

调试代码

测试验证思路是否正确

时间：

timestamp = int(time.time() * 1000)

sign：

md5 = hashlib.md5()
data = "tuling" + str(timestamp) + str(pageNumber)
md5.update(data.encode('utf-8'))
sign = md5.hexdigest()

完整的python代码：

import requests
import timeimport hashlibbase_url = 'https://stu.tulingpyton.cn/api/problem-detail/4/data/'sum = 0
for pageNumber in range(1, 21):timestamp = int(time.time() * 1000)md5 = hashlib.md5()data = "tuling" + str(timestamp) + str(pageNumber)md5.update(data.encode('utf-8'))sign = md5.hexdigest()headers = {"authority": "stu.tulingpyton.cn","method": "GET","scheme": "https","accept": "*/*","accept-encoding": "gzip, deflate, br, zstd","accept-language": "zh-CN,zh;q=0.9","cache-control": "no-cache","cookie": "csrftoken=bUQnx7WcbwsloLWvzCkVFYFqSTDCDN91; sessionid=ri4hj62n9kmc222rtgi60ou2jdryevv7; Hm_lvt_b5d072258d61ab3cd6a9d485aac7f183=1739864249","pragma": "no-cache","priority": "u=1, i","referer": "https://stu.tulingpyton.cn/problem-detail/4/","sec-ch-ua": "\"Google Chrome\";v=\"131\", \"Chromium\";v=\"131\", \"Not_A Brand\";v=\"24\"","sec-ch-ua-mobile": "?0","sec-ch-ua-platform": "\"Windows\"","sec-fetch-dest": "empty","sec-fetch-mode": "cors","sec-fetch-site": "same-origin","user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36",}params = {"page": pageNumber,"sign": sign,"_ts": timestamp}res = requests.get(base_url, params=params, headers=headers)json_data = res.json()print(json_data)for j in json_data['current_array']:sum += jprint(sum)

运行结果：
