我为HTML5制作了一个从我的服务器下载音乐的播放器,如果我从头开始播放歌曲,播放器工作得很好但是当我尝试使用currentTime属性从特定时间播放歌曲时没有任何事情发生,歌曲从开头开始
我的服务器端是Java spring mvc,我的客户端是angularJS。
提示部分:
音频工厂:
tunesApp.factory('audio', function($document) {
var audio = $document[0].createElement('audio');
return audio;
});
播放器工厂:
tunesApp.factory('player', function(audio, $rootScope) {
var player,
playlist = [],
current = {
track: 0
};
player = {
playlist:playlist,
play: function(track) {
if (!playlist.length) return;
if (angular.isDefined(track)) current.track = track;
audio.src = playlist[current.track].url;
audio.currentTime = playlist[current.track].startFrom; // also try with .toString()
audio.play();
}
};
playlist.add = function(album) {
if (playlist.indexOf(album) != -1) return;
playlist.push(album);
};
playlist.remove = function(album) {
var index = playlist.indexOf(album);
if (index == current.album) player.reset();
playlist.splice(index, 1);
};
return player;
});
当我添加歌曲时:
tunesApp.controller('myController', function(player) {
player.playlist.add({
url: "/path/to/server",
startFrom: 65 // in seconds
});
player.play();
});
和服务器控制器获取歌曲:
@RequestMapping(path="/song/{file_id}", method=RequestMethod.GET)
public void getFile(@PathVariable("file_id") String fileId, HttpServletResponse response){
try{
// get the song from the DB
String songName = DB.getSong(fileId);
File file = new File(fullPath + songName);
response.setContentType("audio/mpeg"); // i use only mp3 files
Long length = file.length();
response.addHeader("Content-Range", "bytes 0-" + new Long(length-1).toString()+"/"+length);
response.setContentLength((int)length);
InputStream inputStream = new BufferInputStream(new FileInputStream(file));
FileCopyUtils.copy(inputStream,response.getOutputStream());
response.flushBuffer();
}catch(Exception ex){}
}
这段代码工作了一段时间然后停止工作:(
更新
代码在边缘完美运行,但错误在chrome 44和48
任何帮助?

您可能需要等待" canPlay"在尝试改变时间之前要开火的事件。
借助Chrome桌面和Firefox,您还可以收听“已加载”的内容。事件,告诉您文件是否已加载到您正在寻找的点。
