小i机器人微信版(最新源码，突破403限制)

这个依然是文字版的，而且不支持语音，是通过抓包分析小i机器人wap版的获取。

可以通过扫描下面的二维码或者直接添加微信号xiaoibot进行关注思密达

但是最近小i wap版的demo可能发现有人盗用了，所以把“机器人”封了，如果用之前的方法，会出现403 forbidden的错误，所以我又重新弄了一下，加上了一些浏览器信息，这样就不会封了~

之前不想公布来着，但是没有但是……共享才是王道，大家共同进步。

上代码：

<div style="background:#fdfdfd;color:black;"><u>JavaScript+PHP语言</u>: </div>
<div class="source" style="font-family: '[object HTMLOptionElement]', Consolas, 'Lucida Console', 'Courier New'; color: rgb(246, 243, 232); background-color: rgb(36, 36, 36);"><span style="color: rgb(229, 120, 109);">&lt;?php</span>
