批量下载豆瓣FM加红星的歌曲

打开douban.fm

运行js：

function getPropertyCount(obj) {
    var count = 0,
        key;

    for (key in obj) {
        if (obj.hasOwnProperty(key)) {
            count++;
        }
    }

    return count;
}
var total = $('#rec_liked').text();
var songs = new Object();
function getSongs(songs){
	$.ajax({
		url: 'http://douban.fm/j/mine/playlist?type=n&sid=&pt=0.0&channel=-3&from=mainsite&r=f5b061dff2',
		async: false,
		dataType: 'json',
		success: function(data){
		    for(var i in data['song']){
				songs[data['song'][i]['aid']] = {'title':data['song'][i]['title'], 'url':data['song'][i]['url']};
		    }
			if(getPropertyCount(songs) < 80){
				console.log(getPropertyCount(songs));
				getSongs(songs);
			}
			
		}
	});
};
getSongs(songs);
var str = '';
for(var i in songs){
	str += songs[i]['title']+'|'+songs[i]['url']+"\n";
}
console.log(str);

 把输出的字符串写入文本doubanlist，写个shell脚本download处理

#!/bin/bash
cat $1 | while read LINE
do
    #echo $LINE | awk -F'|' '{print $1}'
    wget -c $(echo $LINE|awk -F'|' '{print $2}') -O "`echo $LINE | awk -F'|' '{print $1".mp3"}'`"
done

 然后shell下面： sh download doubanlist 搞定。

 

等有空看能搞个chrome插件不...
