网易云音乐的相关API

这里的网易云API为Moon大神以及其他大神等得出,本人也抓包进行了验证。Moon大神的文章链接已在文中及结尾列出。

1、歌曲信息:

Get方法:http://music.163.com/api/song/detail/?id=歌曲id&ids=[歌曲id]&csrf_token=
当id正确时返回格式:

{"songs":[{
	"starred":false,

        }],
 "equalizers":{},
 "code":200
}

 

2、 歌曲搜索(需要特定的头信息):

Post方法:http://music.163.com/api/search/pc
必要参数:s:搜索的内容
offset:偏移量(分页用)
limit:获取的数量
type:搜索的类型(歌曲 1 专辑 10歌手 100歌单 1000用户 1002mv 1004歌词 1006主播电台 1009)
返回格式(需使用正确的头信息才能访问,否则403)篇幅过长,略。

3、 歌曲下载:

Get方法:http://music.163.com/api/song/enhance/download/url?br=码率&id=歌曲id
当id正确时的返回格式:

{"data":{
	"id":28445467,
	"url":"http://m10.music.126.net/20161019192149/64bd58d3071e829f606afee85e63d501/ymusic/fe64/c17f/54cc/64c15c1430e55bf2c8093f0b47dc39f4.mp3",
	"br":320000,
	"size":6732382,
	"md5":"64c15c1430e55bf2c8093f0b47dc39f4",
	"code":200,
	"expi":1200,
	"type":"mp3",
	"gain":-1.34,
	"fee":0,
	"uf":null,
	"payed":0,
	"flag":0,
	"canExtend":false},
"code":200}
4、 头信息

必须的参数:cookie appver键值与http Referer

5、专辑、歌单等等

详见moonlib大神的此篇文章:网易云音乐常用API浅析

使用c#调用

c#白痴一枚,抛砖引玉。

1、获取歌曲信息
public static string getMusic(string id) {
            string url = "http://music.163.com/api/song/detail/?id="+id+"&ids=["+id+"]&csrf_token=";

            HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(url);
            req.Method = "get";
            HttpWebResponse response = (HttpWebResponse)req.GetResponse();
            Stream res = response.GetResponseStream();
            StreamReader reader1 = new StreamReader(res);
            string a1 = reader1.ReadToEnd();
	    return a1;
            //string[] a2 = a1.Split(new string[]{"\"mp3Url\":\"","\",\"rtUrls"},StringSplitOptions.RemoveEmptyEntries);
            //this.mp3url = a2[1];
	    }

 

2、获取下载地址
public static string getApiUrl(int kbps, string id)
        {
            return "http://music.163.com/api/song/enhance/download/url?br=" + kbps + "&id=" + id;
        }

public static string getDownUrl(int kbps,string id)
        {
            if (id != "")
            {
                
                string apiurl = getApiUrl(kbps, id);
                HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(apiurl);
                req.Method = "get";
                HttpWebResponse response = (HttpWebResponse)req.GetResponse();
                Stream res = response.GetResponseStream();
                StreamReader reader1 = new StreamReader(res);
                string a1 = reader1.ReadToEnd();
		return a1;
             }
             else
             {
              return("null");
             }

        }
3、 搜索
public string Param(string sname)
        {
            string postls;
            string ss = HttpUtility.UrlEncode(sname,Encoding.GetEncoding("utf-8"));
            StringBuilder bulider = new StringBuilder();
            bulider.AppendFormat("s={0}&offset={1}&limit={2}&type={3}", ss, 0, 20, 1);
            postls = bulider.ToString();
            return postls;
        }
	public static string searchMusic(string sname) {

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(searchurl);
            request.Method = "POST";
            request.Referer = "http://music.163.com/search/";
            request.ContentType = "application/x-www-form-urlencoded";
            string postinfo = Param(sname);
            request.ContentLength = Encoding.UTF8.GetByteCount(postinfo);
            CookieContainer cookies = new CookieContainer();
            Cookie cook = new Cookie();
            Cookie cook1 = new Cookie();
            cook.Value = "1.5.2";
            cook.Name = "appver";
            cook.Domain = "music.163.com";
            cook1.Value = "http://music.163.com/";
            cook1.Name = "Referer";
            cook1.Domain = "music.163.com";
            cookies.Add(cook);
            cookies.Add(cook1);
            request.CookieContainer = cookies;
            Stream myRequestStream = request.GetRequestStream();
            byte[] postm = Encoding.ASCII.GetBytes(postinfo);
            using(Stream reqStream =request.GetRequestStream()){
                reqStream.Write(postm,0,postm.Length);
            }

            HttpWebResponse resp = (HttpWebResponse)request.GetResponse();
            
            Stream strem = resp.GetResponseStream();
            StreamReader a1 = new StreamReader(strem);
            string a2 = a1.ReadToEnd();
            return a2;
            
        }

 

简单的测试成品

使用歌曲下载的api做了个小程序,可实现输入id获取下载链接(通过对字符串的截取和合法性判断等获取mp3直链)并下载。
