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:

  1. define("TOKEN", "xingans"); 
  2.  
  3. $wechatObj = new wechatCallbackapiTest(); 
  4.  
  5. $wechatObj->responseMsg(); 
  6.  
  7. class wechatCallbackapiTest 
  8. { 
  9.    //签名验证公共接口 
  10.    public function valid() 
  11.    { 
  12.        $echoStr = $_GET["echostr"]; 
  13.  
  14.        if($this->checkSignature()){ 
  15.            echo $echoStr; 
  16.            exit; 
  17.        } 
  18.    } 
  19.  
  20.    //主入口处理函数 
  21.    public function responseMsg() 
  22.    { 
  23.        $postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; 
  24.  
  25.        if (!emptyempty($postStr)){ 
  26.                    
  27.            $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); 
  28.            
  29.            $msgType=trim($postObj->MsgType); 
  30.            
  31.            switch($msgType){ 
  32.                case 'text': 
  33.                    $resultStr=$this->handleText($postObj); 
  34.                    break; 
  35.                case 'event': 
  36.                    $resultStr=$this->handleEvent($postObj); 
  37.                    break;
