微信公众平台开发在线点歌功能介绍

微信公众平台的消息接口-音乐消息，这是广大微信公众平台开发者的福音。 根据这一功能，如果能做出在微信中点歌功能，那么我们以后就可以不用安装其他APP， 直接在微信里面关注一个账号，就可以听歌了，还省去了安装的麻烦，而且不用再占用空间。如果音乐资源足够好，那将秒杀一切手机上在线听歌软件也不是没有可能的。

核心代码:public function getMusicInfo() {if ($this->name == ""){$content = array( "Title"=>"","Description"=>"你还没告诉我音乐名称呢？","MusicUrl"=>"","HQMusicUrl"=>"");} else {if (strpos($this->name, "+")){$music = explode("+",$this->name);$url = "http://box.zhangmen.baidu.com/x?op=12&count=1&title=".$music[1]."$$".$music[0]."$$$$";}else{$url = "http://box.zhangmen.baidu.com/x?op=12&count=1&title=".$this->name."$$";}$ch = curl_init();curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);$data = curl_exec($ch);$content = array( "Title"=>"歌曲【".$this->name."】","Description"=>"检索失败","MusicUrl"=>"","HQMusicUrl"=>"");try{@$menus = simplexml_load_string($data, 'SimpleXMLElement', LIBXML_NOCDATA);if ($menus->count > 0 && isset($menus->url[0]) && isset($menus->durl[0])){$url_prefix = substr($menus->url[0]->encode,0,strripos($menus->url[0]->encode,'/') + 1);$url_suffix = substr($menus->url[0]->decode,0,strripos($menus->url[0]->decode,'&'));$durl_prefix = substr($menus->durl[0]->encode,0,strripos($menus->durl[0]->encode,'/') + 1);$durl_suffix = substr($menus->durl[0]->decode,0,strripos($menus->durl[0]->decode,'&'));if (strpos($this->name, "+")){$content = array( "Title"=>$music[1],"Description"=>$music[0],"MusicUrl"=>$url_prefix.$url_suffix,"HQMusicUrl"=>$durl_prefix.$durl_suffix);}else{$content = array( "Title"=>$this->name,"Description"=>"百度音乐提供","MusicUrl"=>$url_prefix.$url_suffix,"HQMusicUrl"=>$durl_prefix.$durl_suffix);}}}catch(Exception $e){}}return $content;}接口调用:include ('music.class.php');$m = new MusicApi($musicContent);$mArr = $m->getMusicInfo();return $this->responseMusic($mArr["Title"], $mArr["Description"], $mArr["MusicUrl"], $mArr["HQMusicUrl"], 0);效果演示：
