本文实例讲述了微信公众号开发之微信公共平台消息回复类。分享给大家供大家参考。具体如下：微信公众号开发代码我在网上看到了有不少，其实都是大同小义了都是参考官方给出的demo文件进行修改的，这里就给各位分享一个。
微信 WeLM WeLM不是一个直接的对话机器人，而是一个补全用户输入信息的生成模型。
下载代码如下:/*** 微信公共平台消息回复类***/ class BBCweixin{private $APPID="******";private $APPSECRET="******";/**文本消息回复*@param array object*@param string content*@return string*/ public function resText($object,$content,$flag=0){$xmlText="%s%d";$resultStr=sprintf($xmlText,$object->FromUserName,$object->ToUserName,time(),$content,$flag);echo $resultStr;exit();}/**图片消息回复*@param array object*@param string url*@return string*/ public function resImage($object,$media_id){$xmlImage="";$xmlImage.="";$xmlImage.="";$xmlImage.="%s";$xmlImage.="";$xmlImage.="";$xmlImage.="";$resultStr=sprintf($xmlImage,$object->FromUserName,$object->ToUserName,time(),$media_id);echo $resultStr;exit();}/**图文消息回复*@param array object*@param array newsData 二维数组 必须包含[Title][Description][PicUrl][Url]字段*@return string*/ public function resNews($object,$newsData=array()){$CreateTime=time();$FuncFlag=0;$newTplHeader="FromUserName}]]>ToUserName}]]>{$CreateTime}%s";$newTplItem="";$newTplFoot="%s";$Content='';$itemsCount=count($newsData);$itemsCount=$itemsCount if($itemsCount){foreach($newsData as $key=>$item){if($key$Content.=sprintf($newTplItem,$item['Title'],$item['Description'],$item['PicUrl'],$item['Url']);}}}$header=sprintf($newTplHeader,0,$itemsCount);$footer=sprintf($newTplFoot,$FuncFlag);echo $header.$Content.$footer;exit();}/**音乐消息回复*@param array object*@param array musicContent 二维数组 包含[Title][Description][MusicUrl][HQMusicUrl]字段*@return string*/ public function resMusic($object,$musicContent=array()){$xmlMusic="%s";if(empty($musicContent[0]['HQMusicUrl'])){$musicContent[0]['HQMusicUrl']=$musicContent[0]['MusicUrl'];}$resultStr=sprintf($xmlMusic,$object->FromUserName,$object->ToUserName,time(),$musicContent[0]['Title'],$musicContent[0]['Description'],$musicContent[0]['MusicUrl'],$musicContent[0]['HQMusicUrl']);echo $resultStr;exit();}/**上传多媒体文件接口*@param*@param array mediaArr filename、filelength、content-type*@return object*/ public function uploadMedia($accessToken,$type='image',$mediaArr){$url="http://file.api.weixin.qq.com/cgi-bin/media/upload?access_token=".$accessToken."&type=".$type;$doPost=self::curlPost($mediaArr,$url);return $doPost;}/**GPS,谷歌坐标转换成百度坐标*@param lnt*@param lat*@return array*/ public function mapApi($lng,$lat,$type){$map=array();if($type=='gps'){$url="http://map.yanue.net/gpsApi.php?lat=".$lat."&lng=".$lng;$res=json_decode(file_get_contents($url));$map['lng']=$res->baidu->lng;$map['lat']=$res->baidu->lat;}if($type=='google'){$url="http://api.map.baidu.com/ag/coord/convert?from=2&to=4&mode=1&x=".$lng."&y=".$lat;$res=json_decode(file_get_contents($url));$map['lng']=base64_decode($res[0]->x);$map['lat']=base64_decode($res[0]->y);}return $map;}/**************************************************************** 使用特定function对数组中所有元素做处理* @param string &$array 要处理的字符串* @param string $function 要执行的函数* @return boolean $apply_to_keys_also 是否也应用到key上* @access public**************************************************************/ public function arrayRecursive(&$array, $function, $apply_to_keys_also = false){static $recursive_counter = 0;if (++$recursive_counter > 1000) {die('possible deep recursion attack');}foreach ($array as $key => $value) {if (is_array($value)) {self::arrayRecursive($array[$key], $function, $apply_to_keys_also);} else {$array[$key] = $function($value);}if ($apply_to_keys_also && is_string($key)) {$new_key = $function($key);if ($new_key != $key) {$array[$new_key] = $array[$key];unset($array[$key]);}}}$recursive_counter--;}/**************************************************************** 将数组转换为JSON字符串（兼容中文）
