发现问题
在一次偶然中，在爬取某个公开网站（非商业型网站）时，老方法，打开调试工具查看请求方式，请求拦截，是否是异步加载，不亦乐乎，当我以为这个网站非常简单的时候，发现二级网页的地址和源码不对应
Ajax异步加载？源码也是这样的
而且这些链接直接访问根本无法访问
用火狐浏览器的event显示：
找到加密方式
源码：
function() { var hh = $(this).attr("href"); if (typeof(hh) == \'undefined\' || hh == \'#\') { return } var aa = hh.split("/"); var aaa = aa.length; var bbb = aa[aaa - 1].split(\'.\'); var ccc = bbb[0]; var cccc = bbb[1]; var r = /^\+?[1-9][0-9]*$/; if (r.test(ccc) && cccc.indexOf(\'jhtml\') != -1) { var srcs = CryptoJS.enc.Utf8.parse(ccc); var k = CryptoJS.enc.Utf8.parse(s); var en = CryptoJS.AES.encrypt(srcs, k, { mode: CryptoJS.mode.ECB, padding: CryptoJS.pad.Pkcs7 }); var ddd = en.toString(); ddd = ddd.replace(/\//g, "^"); ddd = ddd.substring(0, ddd.length - 2); var bbbb = ddd + \'.\' + bbb[1]; aa[aaa - 1] = bbbb; var uuu = \'\'; for (i = 0; i < aaa; i++) { uuu += aa[i] + \'/\' } uuu = uuu.substring(0, uuu.length - 1); window.open(uuu) } else { var ee = $(this).attr(\'target\'); if (ee.typeof(\'undefined\')) { window.location = hh } else { window.open(hh) } } return false }
根据我的发现，实现的效果就是让源码的链接：
http://xxxx.xxxx.xx:80/jssfdg/3254639.jhtml
变为如下链接：
http://xxxx.xxxx.xx:80/jssfdg/JzRnGhk7J9D1ZNMlh47fMw.jhtml
以上代码缩减了下：
就这几行代码：
var srcs = CryptoJS.enc.Utf8.parse(ccc); var k = CryptoJS.enc.Utf8.parse(s); var en = CryptoJS.AES.encrypt(srcs, k, { mode: CryptoJS.mode.ECB, padding: CryptoJS.pad.Pkcs7 }); var ddd = en.toString(); ddd = ddd.replace(/\//g, "^"); ddd = ddd.substring(0, ddd.length - 2); return ddd
大概的意思就是先将那串数字用utf8加密成数组：
再对密钥操作：
再将上面的两个数组用aes加密
将用aes加密过的en转为字符串：
我渣一看这种字符串像是base64加密
再将带有/符号的转为^，因为在url编码中，/符号有特殊意义
再将数据后面的[==]分割掉
最后的字符串就是需要的数据了
把这段操作封装成一个函数，然后测试：
经过测试，没毛病，返回的这个字符与真实的一致。
卧槽，瞬间激动啦，这还没完，我是直接在当前网页的控制台操作的，换到其他网页的控制台：
需要两个重要的东西：CryptoJS对象 和 s变量
CryptoJS对象都还好，那特么一定是引入的，s变量就难了，从源码找，包含s的太多了，而且还是小写，关键词太多了
而且S变量是已经定义好的，因为我打开控制台直接访问s就能有结果：
所以，那绝对是已定义的，但是我无法确定是写死的还是随机生成的，如果按照一定规则随机生成的话，那就难了，所以我必须找到它，它也至关重要，因为就是aes加密需要的密钥，不然无法加密出来希望的格式
我找了一上午，还请教了我的前端大佬同事，也是一时不知道怎么找
最后，我把当天的任务忙完之后，专门腾出两小时时间来再分析，我一个一个js文件慢慢看：
找到key值
结果，他么的，放在jquery源码里面：
而且，还真的是写死的
卧槽!!!!!!!!!!!!!!!!!!!!，太nm骚了，放源码了，按正常人的惯用思维，像什么jquery，vue等的源码，一定是不敢去乱改的，要写js的话，也不敢去乱搞，都是新建一个js文件写入，它这个把密钥写在jquery源码里，简直反其道而行，我不知道说这个网站的前端开发者是高明还是奇葩了
好的，两样东西都齐了，准备用代码实现了，在这之前，先了解下什么是CryptoJS

源码看半天看不懂，我高估了我自己，我搜[ccc]找到了刚才那段加密步骤，找了很多解密方法还没发解密
这里强烈推荐火狐浏览器，就是他妈的牛逼，用火狐可以嗅探到js的事件，而且还显示解密过的js，对的，就是最开始那段代码，具体往上滑，还可以看到源码，以及这段代码在源码文件的哪个位置
那好的，加密过程我们已经知道了
用python实现加密解密
先选用js2py库来跑js代码：
报错，提示没有引入CryptoJS对象
将crypo-js的源码保存到本地js文件里，放在当前目录，
引入crypo-js，还是不行，我傻了，这个需要在当前环境运行的
最后，搞来搞去还是没法，这条路走不通了，最后网上查了下，还是有很多人遇到我这样的问题，并且有的已经解决了的，我开始慢慢找跟我的情况一样的，发现python自己有一个加密库—— Crypto
我研究了半天这个库，pypi文档上看了一遍也没发现个什么东西，跟我用来解密还是有些距离
真的没法了吗？
我想了半天，我觉得我都已经到这一步了，为什么还是不行，一定有我没注意到的情况，最后网上找了很多篇相关的文章，找到如下代码可行，但是到底是哪篇文章我已经不知道了，感谢这位老哥，源地址我真找不到了：
from Crypto.Cipher import AES import base64 def add_to_16(s): while len(s) % 16 != 0: s += (16 - len(s) % 16) * chr(16 - len(s) % 16) return str.encode(s) # 返回bytes def get_secret_url(text, key=\'qnbyzzwmdgghmcnm\'): aes = AES.new(str.encode(key), AES.MODE_ECB) # 初始化加密器，本例采用ECB加密模式 encrypted_text = str(base64.encodebytes(aes.encrypt(add_to_16(text))), encoding=\'utf8\').replace(\'\n\', \'\') # 加密 encrypted_text = encrypted_text.replace(\'/\', "^") # ddd.replace(/\//g, "^") return encrypted_text[:-2] def get_real_url(first_url, key): aa = first_url.split(\'/\') aaa = len(aa) bbb = aa[aaa - 1].split(\'.\') ccc = bbb[0] secret_text = get_secret_url(ccc, key=key) return first_url.replace(ccc, secret_text) url = \'http://xxx.xxxx.xxx.xxx.cn:80/xxxx/938848.jhtml\' key = \'qnbyzzwmdgghmcnm\' # 此处问加密key值 url = get_real_url(url, key=key) print(url)
