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：

}],
 "equalizers":{},

}

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 1002
    • mv 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。

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,

    "fee":0,
    "uf":null,
    "payed":0,
    "flag":0,
    "canExtend":false},
 "code":200}

头信息

必须的参数：cookie appver键值与http Referer

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。

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];
}

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");
    }

}

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。
