网站开发：爬取一拨网易云音乐的歌词

啦啦啦，之前一直在做个音乐网站，然后涉及到了歌词，可当时自己不懂歌词的爬取链接，所以一直采用的手录歌词的方法，费时又费力。前两天在一篇CSDN文章上发现了网易云的歌词链接。然后就立马利用起来爬取一拨歌词...链接如下所示

http://music.163.com/api/song/lyric?id="+id+"&lv=1&kv=1&tv=-1

链接里面其实返回的是包含歌词的json信息，如果要得到纯歌词，还要对其进行一番提取。目前可以操作json的jar包也还挺多的。不过嘛，我也没心思去学习使用，所以一般都是自写方法去提炼需要的信息，虽然麻烦点，但也还好啦，能得到想要的结果。

如下是爬取歌词的代码

1.首先定义二维数组，包含所有要下载歌词的歌曲名以及在网易云音乐上的id

private static String song[][]={
    			{"25643328","信仰-张信哲"},{"254574","后来-刘若英"},{"174934","无颜女-徐良,小凌"},{"174962","和平分手-徐良"},{"26609879","情话-徐良,孙羽幽"},
    			{"174960","犯贱-徐良"},{"174961","红装-徐良"},{"25918133","那时雨-徐良"},{"27890395","抽离-徐良,刘丹萌"},{"174963","客官不可以-徐良,小凌"},
    			{"26609877","七秒钟的记忆-徐良,孙羽幽"},{"375381","不想长大-S.H.E"},{"354620","只对你有感觉-飞轮海 ,田馥甄"},{"167815","情侣装-许嵩"},{"394748","棉花糖-至上励合"},

    			{"29764562","作曲家"},{"133998","老街"},{"27678655","李白"},{"149787","我不是没脸的男孩"},{"25864481","微情歌"},
    			{"149751","那些学校没有教过的事儿"},{"25640407","一千个分手的理由"},{"149778","最简单的声音"},{"149789","致命的甜蜜"},{"149763","毕业后你不是我的"},
    			{"167888","认错"},{"167873","多余的解释"},{"167827","素颜"},{"167876","有何不可"},{"553755659","可不可以-张紫豪"},
    			{"175072","不再联系-夏天Alex"},{"28661853","我配不上你-夏天Alex"},{"69827","太多-陈冠蒲"},{"156193","为你写诗"},{"1330348068","起风了"},

    			{"27955654","其实-薛之谦"},{"32192436","绅士-薛之谦"},{"32507038","演员"},{"163123","秋天不回来-王强"},{"5256103","死了都要爱"},
    			{"19081573","Util You"},{"2006865","Only Love"},{"19081569","Breathless"},{"21157332","One Day"},{"472361096","Despacito (Remix)"},
    			{"25795016","有没有人告诉你-陈楚生"},{"165367","三国杀-汪苏泷"},{"36990266","Faded-Alan Walker&Iselin Solheim"},{"150361","三国恋-Tank"},{"77437","2002年的第一场雪-刀郎"},

    			{"126443","窗外"},{"482999696","夏至未至"},{"483671599","追光者"},{"569200213","消愁"},{"569213220","像我这样的人"},
    			{"28481105","机器铃 砍菜刀-张卫"},{"28240119","倍儿爽-大张伟"},{"413829859","童话镇-暗杠"},{"95843","栀子花开-何炅"}
    	};

2.接下来写方法爬取

/**
     * @desc 爬取歌词并下载
     * @author zcl
     * @date 2019年4月5日
     * @param id	歌曲的id
     * @param name	歌曲名
     * @throws IOException
     */
    public static void downloadLyric(String id,String name) throws IOException{
    	String lyricUrl="http://music.163.com/api/song/lyric?id="+id+"&lv=1&kv=1&tv=-1";
    	Document doc=Jsoup.connect(lyricUrl).get();
    	String lyric=doc.toString();
    	lyric=lyric.substring(lyric.indexOf("lyric\"")+8, lyric.indexOf("klyric")-4);//去掉其他json格式
    	lyric=lyric.replace("\\n", "\r");//\n替换为\r
    	writeToFile(lyric, name);
    }

3.再接下来定义方法，将爬取到的歌词下载至本地文件中

/**
     * 输出歌词至指定文件中
     * @desc 
     * @author zcl
     * @date 2019年4月5日
     * @param lyric	爬取的歌词
     * @param name	歌曲名即保存的文件名
     * @throws IOException
     */
    public static void writeToFile(String lyric,String name) throws IOException{
    	File file=new File("E:/AAAA/alyric/"+name+".txt");
    	file.createNewFile();
    	
    	FileOutputStream fos=new FileOutputStream(file);
    	fos.write(lyric.getBytes());
    	System.out.println("已保存《"+name+"》的歌词至“"+file.getAbsolutePath()+"”文件");
    }

4.最后，在main函数中执行循环来逐个下载歌词。

for(int i=0;i<song.length;i++){
    	downloadLyric(song[i][0],song[i][1]);
    }
