php实现基于微信公众平台开发SDK(demo)扩展的方法 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 = 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');

$cityId=''; foreach($zoneArr as $value){ if($zone==$value['citynm']){ $cityId=$value['weaid']; break; } } if(!emptyempty($cityId)){ $data=file_get_contents("http://api.k780.com:88/?app=weather.today&weaid=$cityId&appkey=10638&sign=3736578f099375665f9f141a6326b757&format=json");

$tmpStr = implode( $tmpArr ); $tmpStr = sha1( $tmpStr ); if( $tmpStr == $signature ){ return true; }else{ return false; } } } 希望本文所述对大家的php程序设计有所帮助。
