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。
