前言 一、页面分析 二、数据获取 三、总结前言
目标网站:aHR0cHM6Ly9iei56enptaC5jbi9pbmRleA==
一、页面分析
进到首页后,翻页一下,就可以看到目标接口,翻页的时候会出现滑块,抓包看下参数,会有个debugger,直接右键跳过即可,然后某些网页如果特别卡的话,都是一些定时器在作怪,直接输入下面这一行搞顶
for (var i = 1; i < 99999; i++) window.clearInterval(i);
时曾相识的参数,翻了翻之前的文章,我记得我是写过的,竟然没找着
后来才记起是写在了公众号上:python爬虫和阿J的逆向
所有的步骤基本是一样的,就是最后用到校验后的数据captcha,是不需要再经过base64编码的
二、数据获取
可以看到返回数据也是做了加密的处理嗷,直接跟栈找解密位置吧
就一直网上根根就找到了解密的位置
掉了三个函数,看不懂啥类型的解密,直接扣他完事

返回数据的i,就是图片的id了,拿着图片id去请求接口即可
