Directives can't play multiple audio file

[iflamed]

Example:

音乐播放指令
AudioPlayer.Play

use \Baidu\Duer\Botsdk\Directive\AudioPlayer\Play;

$directive = new Play('http://www.music', Play::REPLACE_ALL); 
return [
    'directives' => [$directive],
    'outputSpeech' => '正在为你播放歌曲',
];

My code:

use \Baidu\Duer\Botsdk\Directive\AudioPlayer\Play;

$directive = new Play('http://www.music1', Play::ENQUEUE); 
$directive2 = new Play('http://www.music2', Play::ENQUEUE); 
return [
    'directives' => [$directive, $directive2],
    'outputSpeech' => '正在为你播放歌曲',
];

As in my code, Dueros just play the first one music.

考虑到最终设备同时只会播放一首音乐。不能一次返回多个播放音乐的指令，如果要让设备连续播放多首歌，应该是监听audioplayer.playbacknearlyfinished事件，在接收到这个事件后，返回一个directive指令，而且是Play::ENQUEUE
