php实现基于微信公众平台开发SDK(demo)扩展的方法_PHP

本文实例讲述了php实现基于微信公众平台开发SDK(demo)扩展的方法。分享给大家供大家参考。具体分析如下：

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:

define("TOKEN", "xingans"); <br />$wechatObj = new wechatCallbackapiTest(); <br />$wechatObj->responseMsg(); <br />class wechatCallbackapiTest <br />{ <br />   //签名验证公共接口 <br />   public function valid() <br />   { <br />       $echoStr = $_GET["echostr"]; <br />       if($this->checkSignature()){ <br />           echo $echoStr; <br />           exit; <br />       } <br />   } <br /> <br />   //主入口处理函数 <br />   public function responseMsg() <br />   { <br />       $postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; <br />       if (!emptyempty($postStr)){ <br />           $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); <br />           $msgType=trim($postObj->MsgType); <br />           <br />           switch($msgType){ <br />               case 'text': <br />                   $resultStr=$this->handleText($postObj);
