基于微信公众平台开发SDK(demo)扩展例子
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 (! empty empty ( $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' ); $zone =mb_substr( $obj ->Content,0,-2, 'utf-8' ); if ( $keyword == '天气' && ! empty empty ( $zone )){ $zoneArr =json_decode( file_get_contents ( 'http://api.k780测试数据:88/?app=weather.city&format=json' ),true); $zoneArr = $zoneArr [ 'result' ]; $cityId = '' ; foreach ( $zoneArr as $value ){ if ( $zone == $value [ 'citynm' ]){ $cityId = $value [ 'weaid' ]; break ; } } if (! empty empty ( $cityId )){ $data = file_get_contents ( "http://api.k780测试数据:88/?app=weather.today&weaid=$cityId&appkey=10638&sign=3736578f099375665f9f141a6326b757&format=json" ); $data =json_decode( $data ); $contentStr = "今天是:" . $data ->result->days.
