0. 状态

该第二版 API 为最新版本，返回结构有大幅度变动，交互地址有个特征 weapi

1. 总览

所有交互需要指定两个参数：

key value referer http://music.163.com Cookie os=uwp; osver=10.0.10586.318; appver=1.2.1;

下面列出的所有参数均为明文参数，实际提交需要进行加密，详见最下方第 7 条目

http://m8.music.126.net/[expTime]/[token]/ymusic/[key1]/[key2]/[key3]/[MD5].mp3

7. 加密请求

实际请求的参数应当加密为如下形式：

params: Db3xGrqMzXwQqWAIe7AlqILYssUuypZlUS+6Dr8g//OEK8SPpjsZht2j+/C+UZ/rAh1bsXoFDEZxQUwdVB5oc1nSRRT3gpmRgzmwhR8yBCboIk+Uf8PvV2azs2WQ10zewCEps4IAIW1Dbes4jxGcEh7pmUXurQQcrjf9VjzOp64XwKuzunQbb0JG8CwybMIyHjWAC6osTnopHVkSikLsMggTLCVADoK3s+a75VWaYY0srdCoS3FJq8tvvnVGim6k3TpsFkiII/r5DCm8EyvfLrZcsiB5Kpx96ZjxZXYw4yU=

encSecKey: 8ac3219a491bfde0c81532fb4d6c8cd919cc2613631f11a82a72a1fd02e535eb5fbce3c51e7bb8ad2ba06590c391ddec326aa6d6535f36bcb2dd074cf9601f1e874fbfe96787f341d824ea8f03781713355e745472949cb44d8b4c6ed1c76944e2d684add7e746f8ab6119caa7270dd3373320345d946dfb2647c66ab6ef51e5

其中 params 为 AES 对称加密后的参数，encSecKey 为 RSA 加密后的 AES 密钥。所有公钥等参数详见代码，这里不列出。

1. 生成 AES 密钥

AES 密钥需要随机，否则服务器会 dump 掉相同密钥的请求（数量多的话）。密钥的形式为 16 位随机字母或数字，[0-9a-zA-Z]

function createSecretKey($length=16){ $str='0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'; $r=''; for($i=0;$iaes_encode($string,$this->_nonce); $data['params']=$this->aes_encode($data['params'],$this->_secretKey);

AES 加密的具体算法为:AES-128-CBC，输出格式为 base64 AES 加密时需要指定 iv：0102030405060708

本步骤加密后的结果即为 params

3. RSA 加密

最后对第一步生成的 secretKey 进行 RSA 加密，不过这个加密非常诡异，不是标准的形式。下面引用 darknessomi 的结论

RSA 加密采用非常规填充方式，既不是 PKCS1 也不是 PKCS1_OAEP，网易的做法是直接向前补0 这样加密出来的密文有个特点：加密过程没有随机因素，明文多次加密后得到的密文是相同的然而，我们常用的 RSA 加密模块均不支持此种加密，所以需要手写一段简单的 RSA 加密加密过程 convertUtf8toHex(reversedText)^e%N 输入过程中需要对加密字符串进行 hex 格式转码

PHP 中需要使用大数运算类，如果嫌不够清真的话可以自己实现，需要使用快速幂算法加速

function rsa_encode($text){ $rtext=strrev(utf8_encode($text)); $keytext=$this->bchexdec($this->strToHex($rtext)); $a=new Math_BigInteger($keytext); $b=new Math_BigInteger($this->bchexdec($this->_pubKey)); $c=new Math_BigInteger($this->bchexdec($this->_modulus)); $key=$a->modPow($b, $c)->toHex(); return str_pad($key,256,'0',STR_PAD_LEFT); } function bchexdec($hex){ $dec=0; $len=strlen($hex); for($i=0;$i
