该扩展基于官方的微信公众平台sdk,这里只做了简单地封装,实现了一些基本的功能,如天气查询,翻译,自动聊天机器人,自定义菜单接口)仅供学习之用.代码如下:
responsemsg();class wechatcallbackapitest { //签名验证公共接口 public function valid() { $echostr = $_get[echostr]; if ($this->checksignature()) { echo $echostr; exit; } } //主入口处理函数 public function responsemsg() { $poststr = $globals[http_raw_post_data];
