一:学习目的
因进来做一个Android MP3播放器项目,需要用到歌词本地同步和在线同步,本地不存在在通过WiFi或GPRS从网络上获取;
二:学习API的网址:
http://api.geci.me/en/latest/index.html#indices-and-tables 三:学习前掌握的知识:
1)看的懂Json数据格式;
2)如果想深入了解此API要了解汉字和Unicode的转换!
四:学习内容
主要可以通过一下方式来获取歌词:
1) 根据歌曲名来获取歌词
2) 格局歌曲名和歌手名获取歌词
3) 根据歌曲编号获取歌曲URL
4) 根据专辑编号获取专辑封面URL
五:详细分析
<一>:根据歌曲名来获取歌词
1) 请求地址: http://geci.me/api/lyric/:song
2) 返回歌词格式: json字符串
3) 请求方式是:get方式;
Eg:查找“海阔天空”的歌词;url:http://geci.me/api/lyric/海阔天空
获取到的json数据格式如下:

这并非我们所找歌曲的歌词,而是在歌词迷库中存在的不同版本歌曲歌词的url;
从这里看有15个版本(坑爹啊);
{"aid": 1563419, "lrc": "http://s.geci.me/lrc/166/16685/1668536.lrc", "artist": "Beyond", "song": "\u6d77\u9614\u5929\u7a7a", "sid": 1668536}
Aid: 经多次测试,得到此编号指
Lrc:歌词的路径;
Artist:Beyond –歌手名字
Song: 海阔天空—歌曲名称;
Sid:是歌词编号;
<二>:根据歌曲名和歌手名获取歌词
1) 请求地址: http://geci.me/api/lyric/:song
2) 返回歌词格式: json字符串
3) 请求方式是:get方式;
Eg:查找黄秋生的“海宽天空” http://geci.me/api/lyric/海阔天空/黄秋生
<三>:根据歌曲编号获取歌词URL
1) 请求地址:http://geci.me/api/cover/:album_id
2) 返回歌词格式: json字符串
3) 请求方式是:get方式;
Eg:

{"aid": 1563419, "lrc": "http://s.geci.me/lrc/166/16685/1668536.lrc", "artist": "Beyond", "song": "\u6d77\u9614\u5929\u7a7a", "sid": 1668536}, 

知道了以上信息可以通过http://s.geci.me/lrc/166/16685/1668536.lrc中1668536或sid获取歌词路径;


<四>:根据专辑编号获取专辑封面URL
1) 请求地址:http://geci.me/api/cover/:album_id
2) 返回歌词格式: json字符串
3) 请求方式是:get方式;
Eg:查找“海阔天空”的专辑封面:
首先要通过第一步(歌曲名称查询获取信息);

以第一个版本为例:

{"aid": 1563419, "lrc": "http://s.geci.me/lrc/166/16685/1668536.lrc", "artist": "Beyond", "song": "\u6d77\u9614\u5929\u7a7a", "sid": 1668536},



(1) http://geci.me/api/cover/aid 

即:http://geci.me/api/cover/1563419


返回一个json字符串:

{"count": 1, "code": 0, "result": {"cover": "http://s.geci.me/album-cover/156/1563419.jpg", "thumb": "http://s.geci.me/album-cover/156/1563419-thumb.jpg"}} 

主要看cover对应的值:http://s.geci.me/album-cover/156/1563419.jpg和thumb对应的值:http://s.geci.me/album-cover/156/1563419-thumb.jpg;


Cover和thumb对应的都是专辑封面的路径,但是thumb对的是小图片;
