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"); 

$wechatObj = new wechatCallbackapiTest(); 

$wechatObj->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"]; 

       if (!emptyempty($postStr)){ 

           $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); 

           $msgType=trim($postObj->MsgType); 

           

           switch($msgType){ 

               case 'text': 

                   $resultStr=$this->handleText($postObj); 

                   break; 

               case 'event': 

                   $resultStr=$this->handleEvent($postObj); 

                   break; 

               default: 

                   $resultStr=$this->handleDefault($postObj); 

                   break; 

           } 

           echo $resultStr; 

           

       }else { 

           echo "Error"; 

           exit; 

       } 

   } 

   

   //处理文本消息 

      private function handleText($obj){ 

          $keyword=trim($obj->Content); 

          if(preg_match('/天气/',$keyword)){ 

              $contentStr=$this->handleWeather($obj); 

          }elseif(preg_match('/翻译/',$keyword)){ 

              $contentStr=$this->handleTranslation($obj); 

          }else{ 

              $contentStr=$this->handleChat($obj); 

          } 

          return $this->handleStr($obj,$contentStr); 

      } 

      

      //处理天气 

      private function handleWeather($obj){ 

          $keyword=mb_substr($obj->Content,-2,2,'utf-8');
