【js逆向_入门】图灵爬虫练习平台 第四题

(base64解码）地址：aHR0cHM6Ly9zdHUudHVsaW5ncHl0b24uY24vcHJvYmxlbS1kZXRhaWwvNC8=

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 time

import hashlib

base_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": "*/*",

    }
    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 += j

print(sum)

运行结果：
