美团拼图滑块

有时候放弃也是一种智慧。

就像这说的一样，美团的拼图滑块，不知道这个缺口该怎么去处理，正常划顶到最外面去了，所以就不知道这个是咋计算的。

先来看看他的这个加密，跟原来的一划到底其实是一样的，难度只是在轨迹的处理上，我觉得还是一划到底简单点，然后的话拼图滑块取消了sign跟sess的计算。

这就叫给你关了一扇门，又给你打开了一扇窗，各有各的难。

behavior值：包含了时间，滑动距离的验证。

token也是一样的流程：然后轨迹信息在这个ft,mt中，mt为倒叙的behiver_info['trajectory'][0]['point']信息，这个可以去看看，不过最后一个时间值不同，找了几次规律发现时间差为37,47。大家也可以去试试看。

分享一个自己写的轨迹处理：

还有个难点就是这个请求头的Authencation值，hock一下看看。

(function() {var org = window.XMLHttpRequest.prototype.setRequestHeader;window.XMLHttpRequest.prototype.setRequestHeader = function(key, value) {console.log(key, ':', value)if (key == 'Authencation') {debugger ;}return org.apply(this, arguments);};
}
)();
