jQuery+JSON+jPlayer实现QQ空间音乐查询

这里使用jQuery和jPlayer来实现QQ空间音乐的查询。

我们要使用的接口位于bejson接口页面中的音乐接口栏里。

QQ音乐接口地址:

http://qzone-music.qq.com/fcg-bin/fcg_music_fav_getinfo.fcg?dirinfo=0&dirid=1&uin=QQ号&p=0.519638272547262&g_tk=1284234856

这里给出核心代码:

1.gtk参数的获取方式

f

unction getGTK() {
  var str = "@HR3etVm80";
  var hash = 5381;
  for (var i = 0,
  len = str.length; i < len; ++i) {
    hash += (hash << 5) + str.charAt(i).charCodeAt();
  }
  var gtk = hash & 0x7fffffff;
  //document.getElementById("gtk").value = gtk;
  return gtk;
}

2.请求QQ空间接口

function getMusicId() {
var qqNo = document.getElementById("qqNo").value;
var url = 'http://qzone-music.qq.com/fcg-bin/cgi_playlist_xml.fcg?uin=' + qqNo + '&json=1&g_tk=' + getGTK();
$.getScript(url);
}

3.回调拼装JSON

根据返回的JSON接口

我们来解析音乐JSON

function jsonCallback(data) {
  if(data.code==1){
    alert(data.msg);
    return;
  }
  var songs = data.qqmusic.playlist.song;
  var dataStr = "[";
  for (var i = 0; i < songs.length; i++) {
    dataStr += "{";
    dataStr += "title:'" + songs[i].xsong_name + "',";
    dataStr += "mp3:'" + songs[i].xsong_url + "'";
    dataStr += "}";
    if (i < songs.length) {
      dataStr += ',';
    }
  }
  dataStr += ']';
  eval("ds=" + dataStr);
  newPlayer(ds);
}

最后我们调用jPlay播放器:

var playList;
function newPlayer(data) {
  playList = new jPlayerPlaylist({
    jPlayer: "#jquery_jplayer_1",
    cssSelectorAncestor: "#jp_container_1"
  },
  data, {
    swfPath: "js",
    supplied: "mp3",
    wmode: "window"
  });
}
