以上代码来自https://zhuanlan.zhihu.com/p/32473340
考虑到很多同学没有Python环境，用起来并不是很方便，故参考此代码改写成Java版本。
另外简单写了个Web版提交工具，

但是不管哪种方法，都需要手动抓取微信跳一跳小游戏的session_id，抓包方法可以参考下面的或者自行搜索相关资料。
安卓抓包参考：安卓下使用Packet Capture抓取微信跳一跳小游戏的session_id值
iOS抓包参考：iOS下抓取微信跳一跳小游戏的session_id值
Java实现：
这里写了两个类，一个PKCS7加密的单独类，（参考自 WindCoder）

目前观察当执行errcode为0时代表成功，此时需要结束杀死微信的后台进程，重新进入微信，打开跳一跳小游戏，可以查看自己的分数，分数千万不要太高，我目前设置过的最高分是1024分，没有被封。
