这篇文章主要介绍了php实现基于微信公众平台开发SDK(demo)扩展的方法,包括处理文本消息、天气、翻译、聊天信息及自定义菜单等,需要的朋友可以参考下

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:

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