前言

继续，还是猿人学的，既然之前已经开了篇，那么这个系列就会一直更下去

分析

开始分析，打开页面：
python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

还是这样的，要翻完5页，然后才能得到结果，老路子，打开浏览器的调试工具翻页看看，刚点击翻页，我去，这cookie有效期有点短啊

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

那重新抓包吧，

又出现这个：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

鼠标放到那一行右键，然后如下：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

继续抓包看看，点xhr：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

还是很轻易的就拿到它的接口，然后，第二题标题已经说了，动态cookie，那么看看cookie：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

相信根据老哥你的经验，Hm开头的都是百度自己生成的无关的cookie，然后我标注出来的m才是这个站点验证的cookie，sessionid只是服务端验证的登录状态，就不多说了

那我们着重看这个m，这个值跟第一题很像啊，目测唯一的区别就是后面的时间戳，没有再去掉最后三位数了，竖线还是有那我们搜竖线看看，

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

太多了，直接加载都要半天，换个思路

直接全局搜前面的值840c49ccdac8e80377c306987e6da346吧，一搜发现这么多都有：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

点击第一个搜索结果：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

第一个出现的是这个2相关的，而它这已经都带上了，那说明在这个2之前就已经在某个地方生成好了，在2之前看看有没有可疑的请求，过滤掉css，js，图片等资源文件以外，也就上面这5个了

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

为什么是五个，一个一个点进去看下，倒数第5个：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

倒数第4个：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

倒数第3个：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

倒数第2和第1个都是如下：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

补充下，为什么上面4个都是Failed to load response data，正常情况下是只有一个的，多了3个是因为我刚才多刷新了几次，具体刷了几次我也忘了，按理是只有一个Failed to load response data的

奇怪，没东西了啊，是吧？真的没有嘛？这个调试工具Failed to load response data的就真的没有东西吗？

按正常逻辑，这确实没有东西了啊，而出现这个通常是重定向的时候会这样，那么看它这同一个网址，加载多次，确实符合重定向的逻辑，有经验的想到这，估计直接就去找有没有location和reload相关的字眼了，而这里，也就只有这里才有可能有东西了，这可咋整呢？打开抓包工具刷新看看吧：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

确实只有2个，点开第一个：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

点开第2个：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

对上了是吧，第二个就是实际的html源码，第一个就是一段js，生成cookie的逻辑大概率就在里面了，我们把第一个里的结果复制出来，放到文本文件里

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

先把script标签里的内容抠出来，存到js文件里：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

卧槽，全是一堆这种东西，简直头皮发麻，算了，放弃了，今天的分析就到这里吧

。

哈哈哈，开.....开个玩笑，学习为大，分析还是要分析的，那这种东西是啥呀，看到又有\x开头，先去解码看看，还是这个网站：https://tool.lu/js/

解完看了下，变量名基本都是_0x开头的，可读性很差，这种咋办呢？

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

这里就不多说了，就是ob混淆，全名是obfuscator，国外的js混淆天花板的存在，具体就自己研究了，后面有空的话可以针对性的搞一波分析，要想解ob混淆的话，得用AST了，有关AST的我之前更新过一两篇，到现在一直是搁浅状态，因为之前因为一点事耽搁了，后面AST系列也会针对性的出完的。

那么我们怎么取解，难道真的要先去学AST吗，暂时不用，先回到网页，点采集分析工具，里面有ob解混淆的

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

把代码放进去，解析，注意，这里要把原始的js字段放进去解，不要用上面16进制转码过的来解了，不然会接口报错：

解完复制出来放到一个js文件里：

找到关键点

搜下有没有cookie相关的，一搜就搜到了，那就确定是这里了：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

接下来就是老套的源码分析了

先缩一下代码：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

就三个主的方法，setInterval是这是延迟调用

从下网上看，最后有个【$dbsm_0x2d44cd】的方法

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

看到有4处调用，从下到上，先看这个setInterval，马德，这方法有个形参的，结果你什么都没传啊

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

什么都不传的话，现在看看【$dbsm_0x2d44cd】什么逻辑，他这意思是不管有没有传，都要用到上面的_0x460b39

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

再看下_0x460b39的逻辑，上面的参数传了个0，0的话就不是字符串了，走下面的逻辑

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

到后面这个逻辑

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

为真，然后看后面的debugger啥的是啥：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

我一敲回车，立马这样：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

那看来这段代码就是刚才看到的debugger反调试了，那问题不大，直接删除了，根本不是我们要找的cookie生成部分，直接把选中部分删除了:

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

继续往上看，现在就只有那个自执行函数了，直接把这个函数的函数体搞出来吧，也不要他自执行了，删除之后继续从下网上看：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

_0x46a335就是个时间对象了，_0x368659就是核心逻辑部分了

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

就是生成个值赋值给document的cookie属性，然后再重载（刷新）下这个页面了，这也正好符合了开头我们猜测的重定向逻辑，这里不多说，那么和兴的逻辑就在这一段了：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

对比下接口的cookie:

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

格式至少对上了，说明我们找对地方了，继续看：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

照上面的格式，是不是感觉这里这个方法_0x51d374有点多余了，因为上面的格式，m=就完了，中间本来就没有值，不用说，他返回的一定是个空值，但是空值就一定是多余的吗？

这里先留着，放一放，看后面的_0x215c50，先看这个：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

唉~，_0x51d374又被调用过了，那就必须看下了：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

但是发现，根本没有实际的可用return啊，还是再放一放吧，看后面的这个：

_0x55f05d ? _0x1e18d9 ? _0x323adc(_0x55f05d, _0x3bb96a) : y(_0x55f05d, _0x3bb96a) : _0x1e18d9 ? _0x301123(_0x3bb96a) : _0x3e981c(_0x3bb96a);

一个有点长的三元操作运行，直接分解来看：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

意思就是，如果_0x55f05d成立，就会去执行第二行的代码，如果不成立就是执行最后一行的代码，

但由于_0x215c50只传了一个参数，那后面两个参数一定没有，那么_0x55f05d一定不成立

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

那么就必然会执行最后一行代码：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

_0x3e981c方法里面就是实际的加密和解密了

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

唯一要注意的是，这里的gz，貌似是外部变量，仔细一搜，恰恰就是刚才提了那句返回为空就真的没用的那个方法里的：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

抠出实际代码

在python里调用看看，ok，正常返回结果：

python爬虫 - js逆向之猿人学第二题cookie验证+ob混淆

python实现

接下来就是用这个cookie去请求翻页了，成败就在此一举了

直接上代码了

    'user-agent': 'yuanrenxue.project',
    'x-requested-with': 'XMLHttpRequest'
}


def get_m():
    f = open('cookie_decode.js', encoding='utf-8')
    cont = f.read()
    f.close()
    js = execjs.compile(cont)
    return js.call('get_m')

    url = f'https://match.yuanrenxue.com/api/match/2?page={page}'
    m = get_m()
    cookie = {'cookie': f'sessionid='换成你的账号id'; {m}'}
    headers.update(cookie)
    req = requests.get(url, headers=headers)
    res = req.json()
    data = res.get('data')
    data = [temp.get('value') for temp in data]
    print('temp', data)
    return data
