上篇说到微信公众账号的几个坑，前面五个，已经说到菜单，宝宝继续往下赘述了。可惜，还不知道宝宝的宝宝到底是不是心疼宝宝呢，完了，我凌乱了。。。
回到正题，我们就不吐槽其他的了，上一篇说到微信的菜单了，那么，我们现在说说菜单回复等等的吧。
菜单回复是需要处理XML文件的，我们根据微信返回的XML文件，可以得到每个微信用户相对于微信公众号的唯一标识。微信公众平台的机制简单的将就是我们自己输出固定格式的xml文件，然后微信APP负责解析，得到我们想要的信息，然后对信息统一处理。
第六坑，如果你看微信文档，那么，绝对坑死你，上图。这里的ToUserName和FromUserName一定特么的要分清楚了，记住，千万不要写反了，用户对于微信而言是A→B，那么微信对于用户就是反着来的，貌似现在应该说清楚了。
