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:

publicfunctiongetMusicInfo(){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');$m=newMusicApi($musicContent);$mArr=$m->getMusicInfo();return$this->responseMusic($mArr["Title"],$mArr["Description"],$mArr["MusicUrl"],$mArr["HQMusicUrl"],0);
