前言
在这里我就不再一一介绍每个步骤的具体操作了，因为在爬取老版今日头条数据的时候都已经讲的非常清楚了，所以在这里我只会在重点上讲述这个是这么实现的，如果想要看具体步骤请先去看我今日头条的文章内容，里面有非常详细的介绍以及是怎么找到加密js代码和api接口。
Python3爬取今日头条文章视频数据，完美解决as、cp、_signature的加密方法
WAP端跟APP端完全没啥区别，所以能用WAP端就用WAP端爬取数据，APP端涉及逆向APP比较复杂，所以推荐爬取WAP端的数据。

对比提交数据Form Data
因为有拿后续数据的操作，肯定就会有值进行修改，所以我们得需要知道哪些值被修改了，哪些值是固定的，所以对比Form Data尤为重要，看下面的内容就知道问题所在。
下面Name为app的就是返回广告数据的连接地址
第一次请求的Form Data:
数据取出来后进行JSON格式化，可以百度搜索JSON格式化，这样方便我们进行对比。

我们请求了三次，发现广告数据连接的Form Data有变化的只有slot里面的cur、orders_info、current_rot、refresh_type、seq、seq_loid这几个字段。
破解请求Form Data
搜索orders_info得到构造请求Form Data的JS函数，直接开始读源码打断点。
发现我们的构造请求Form Data已经真相大白了，简单吧。
这下我们只需要知道window.SSPAd是怎么生成的即可，直接搜索window.SSPAd。
发现window.SSPAd是new s生成的，搜索var s =，在这里面又发现了我们之前搜索orders_info的时候，orders_info是在requestOrder里面的。
然后通过打断点发现window.orders_info是由getOrderInfo返回的，这个是每次请求返回的结果里面的数据，并且通过观察其他的参数发现，他们都是有规律的，只有orders_info没有规律，所以这一切都联系到了一起了，简单吧。
e.prototype.getOrderInfo = function(e) {
return e.oid + "," + e.advertiser_id + "," + e.product_id + "," + e.product_type + "," + e.industry_id + "," + e.order_source + "," + e.act_type
}
直接上代码
