微信公众平台开发——在线点歌

    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);
