    大家好,好久不见,最近有点忙,今天抽空写一篇今日头条的参数。

    废话不多说,进入正题,前些天看到招聘中有需求提到如果可有今日头条采集加分,我特地去研究了一下,主要难度还是在cp、as和signature这几个参数的生成,主要还是signature最难。

    如图下:

    034c9b3f2278d8ef40139747a272fb03.png

    今天我们主要来讲的是signature参数的生成过程,最先还搜索一下,果不其然,经过多次调试确定了为主,其实就是在这里。

    82fe48ab7ef0615ffa3517eea56bb611.png

    入口就在这里,打游戏断电,进去

    跟进去,到这里就是了。

    ce8804d13a8e5edfd5d9f9fe0c66d68d.png

    主要是生成就是在这个文件里面,其实到这里就基本上可以说了完成了一半,因为整一个文件页没有多少行,复制下来,然后去浏览器运行,当然了,还是要补环境的。

    整一个文件走完出来就是结果了,如图如下:

    08ffcb395a2ac8ba533edfb8867272e7.png

    这个就是结果,但是但是但是,他这个环境检查有点厉害,检查域名,检查浏览器的请求头,检查主域名,然后他这个循坏要一直绕一直绕,所以调了半天。

    主要是一个方法一直在生成加上中的一个关键字段的字符串,如图:

    ee0576d410e11be13597836e3ae59ed2.png

    也就是如下的方法:

    d9ad30fb3b5c066167e5420caa62b274.png

    打印出来就可以看到是吗关键性的字段,然后就是查什么补什么了。

    这是我自己写的封装成的一个方法可以判断返回内容。加上这个就可以了。

    97d231bec6058f78fc8666274ecfccd3.png

    然后就可以用node运行得到想要的结果。

    f284e9eae01c4930d0952980ec02aa30.png

    看起来断了很多,为什么呢????

    因为没有吧cookie加上去,不过无伤大雅,这样也是可以用的,照样畅通无阻。

    好了今天就讲到这里了。

    下一篇说一下怎么使用node搭建一个本地服务来计算这个参数的加密字段,然后就可以直接请求得到想要的结果,为什么要这样呢,因为excejs使用的时候是无法用的计算很久,因为他循坏得太变态了。直接搭建一个本地服务来计算想要的加密计算就可以了。

    欢迎大家关注我的知乎,第一时间理解到我发布的动态,我们一起成长一起变大佬哈哈哈哈。。。。

    公众号即将要来发布app的爬虫,知乎发布js的加密爬虫

    欢迎大家关注我的微信公众号。

    最新今日头条sign加密更新了,抽时间看了看,比上次的加密难度增加了许多。接下来讲下加密流程。

    今日头条获取下一页面的数据时断点位置

    我们只需要找到window.byted_acrawler的生成就可以了。用fiddler拦击服务器返回的的response并添加debugger;

    调试之后会定位到服务器返回的https://sf1-ttcdn-tos.pstatp.com/obj/ttfe/rc/acrawler.js这个js,

    此处为补充:

    这个地方讲的清楚一点,打开这段js的url返回的是

    将第一个return改成console.log(),这段js没有检验任何浏览器特征返回的结果是。新建一个js文件返回的js代码放进去运行,此处也没有检测浏览器特征,在 U.join('')这个地方返回的就是sign的js加密逻辑,此处补充浏览器特征就可以生成window.byted_acrawler.sign这个函数。

    稍稍变化下运行它的的返回结果

    有没有很熟悉这是window.byted_acrawler.sign(a)加密a的代码,此时window.byted_acrawler还没有生成。这段js第一次调用会生成window.byted_acrawler.sign函数,之后加密url生成signature.

    理解了来源之后就是模拟生成了,最简单的方式开一个html引入这段代码,控制台log输出就可以,这种不太适合本地调用,那就需要nodejs环境进行特征模拟了。生成的signature会有两种,主要是

    是否引用这段代码初始化,这个地方特征模拟的时候会涉及部分dom操作,生成的比较详细。不初始化也可以拿到数据,校验的浏览器特征并不太多。理解思路就行,直接上结果吧!

    博主讲的比较粗略,能看懂就行。

    更新 5月11号

    这几天发现今日头条详情页也有个signature加密

    其实和列表页加密的算法几乎一样只是生成算法的参数稍微有点不同,注意

    这个地方的传入就行,然后在跑一遍详情页的代码,纯粹凑篇幅的。

    本文章只用来研究学习,如果侵犯某些网站利益请联系博主删除。博主qq:1458342294
