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：

}],
"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。
