php实现基于微信公众平台开发SDK(demo)扩展的方法

PHP扩展方法微信平台SDK开发 实现
2023-06-13 09:15:37 时间

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:

复制代码代码如下:
define("TOKEN","xingans");
$wechatObj=newwechatCallbackapiTest();
$wechatObj->responseMsg();
classwechatCallbackapiTest
{
  //签名验证公共接口
  publicfunctionvalid()
  {
      $echoStr=$_GET["echostr"];
      if($this->checkSignature()){
          echo$echoStr;
          exit;
      }
  }
 
  //主入口处理函数
  publicfunctionresponseMsg()
  {
      $postStr=$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
     privatefunctionhandleText($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
     privatefunctionhandleWeather($obj){
         $keyword=mb_substr($obj->Content,-2,2,"utf-8");
         $zone=mb_substr($obj->Content,0,-2,"utf-8");
         if($keyword=="天气"&&!emptyempty($zone)){
             $zoneArr=json_decode(file_get_contents("http://api.k780.com:88/?app=weather.city&format=json"),true);
             $zoneArr=$zoneArr["result"];
             $cityId="";
             foreach($zoneArras$value){

                 }
