抓包抓到，好久没做解密了，奥里给干他！：

 搜索关键字，打上断点，点击第二页。

 

 

_0x10a345就是明文已经出现 ，现在就是确定是什么函数解密的。

很明显啊，前一行代码就是疑似解密的位置，打上断点，点击下一页。在控制台打印。

 

OK，已经确定好了解密函数了 。分析这段代码！

JSON['parse'](_0x5401c5['a']['decipher'](_0x38f555['data']['result']))

使用了某种加密算法来解密 data 对象中的 result 字段，然后通过 JSON.parse() 解析得到的解密结果。

具体来说，它首先调用 _0x5401c5['a']['decipher']() 函数对 data['result'] 进行解密，然后将解密后的结果传递给 JSON.parse() 函数进行解析。

那么就找到这个函数的位置，控制台打印

确定位置打上断点

 

_0xzz53b5就是传入的密文，返回的是明文。很明显，这里又嵌套了别的函数。_0x1b12e2(_0x388932(_0xbcd174(_0x2253b5)))

要找到的未定义包括_0x1b12e2，_0x388932，_0xbcd174

你能写一个python获取数据，再调用js代码，对密文进行解密，返回数据的代码吗？

还是我来吧，先把js改进一下，写一个新函数，接收明文，转变为json格式。

function get_data(data) {
            return JSON.parse(_0x1b12e2(_0x388932(_0xbcd174(data))));
};

好了，写一个python来获取密文吧！

import requests
import execjs
headers = {
    'authority': 'api.zzzmh.cn',
    'accept': 'application/json, text/plain, */*',
    'accept-language': 'zh-CN,zh;q=0.9',
    'cache-control': 'no-cache',
    'content-type': 'application/json;charset=UTF-8',
    'origin': 'https://bz.zzzmh.cn',
    'pragma': 'no-cache',
    'referer': 'https://bz.zzzmh.cn/',
    'sec-ch-ua': '"Not_A Brand";v="8", "Chromium";v="120", "Google Chrome";v="120"',
    'sec-ch-ua-mobile': '?0',
    'sec-ch-ua-platform': '"Windows"',
    'sec-fetch-dest': 'empty',
    'sec-fetch-mode': 'cors',
    'sec-fetch-site': 'same-site',
    'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36',
}

json_data = {
    'size': 24,
    'current': 2,
    'sort': 0,
    'category': 0,
    'resolution': 0,
    'color': 0,
    'categoryId': 0,
    'ratio': 0,
}

response = requests.post('https://api.zzzmh.cn/bz/v3/getData', headers=headers, json=json_data).json()
data = response['result']
json_code = execjs.compile(open('demo11.js','r',encoding='utf-8').read())
result = json_code.call('get_data',data)
for value in result['list']:
    print(value)

结果展现：

 

如果想多页爬取，怎么做，分析数据包的参数有什么不同！

 

写个循环，按照页码进行多页爬取 。不知道你有没有想过，得到的数据有什么用呢？

数据中i有什么作用呢？

这是图片的链接url中需要的参数，对比几张不同的图，你有什么发现吗？

 

只有最后那部分在变化，而变化的那部分数据刚好是i所返回的数据。有了i,就有了批量的图片的url,就可以进行批量的采集了。你可以在自己写代码，批量采集图片吗？

插一嘴，这个网站以前是有debugger的，不知为什么，现在没了，更简单了。

这是一个很简单的混淆案例！！！
