Question

我正在尝试访问MusicKit API，但它始终返回401未经授权的错误。我不知道这个。我有以下代码来生成开发者令牌：

const privateKey = fs.readFileSync("resources/AuthKey.p8").toString();  
  const teamId = "MYTEAMID";  
  const keyId = "MYKEYID";  

  const options = {  
    algorithm: "ES256",  
    expiresIn: "180d",  
    issuer: "MYTEAMID", // your 10-character Team ID, obtained from your developer account  
    header: {  
      alg: "ES256",  
      kid: "MYKEYID", // your MusicKit Key ID  
    },  
  };  

  return new Promise((resolve: any, reject: any) => {  
    jwt.sign({}, privateKey, options, (error, token) => {  
      if (error) {  
        return reject(error);  
      } else { // token created  
        return resolve(token);  
      }  
    });  
  });

这将生成一个成功的令牌。解码后，此令牌的标头的值如下：

{  
 "alg": "ES256",  
 "typ": "JWT",  
 "kid": "MYKEYID"  
}

和有效载荷值，例如：

{  
 "iat": 1558197586,  
 "exp": 1573749586,  
 "iss": "MYTEAMID"  
}

我知道Apple没有在标题中指定typ，所以这可能是个问题吗？

然后我尝试在卷曲请求中将其用于样本艺术家，例如curl -v -H 'Authorization: Bearer <MYTOKEN>' "https://api.music.apple.com/v1/catalog/us/artists/36954"，但它返回401错误：

为什么？

Answer 1

不确定使用的是哪个jwt库，以及使用的方法是否正确。

这对我有用：

const jwt = require('jsonwebtoken');
const fs = require('fs')

const APNS_KEY_ID = 'XXXXXXXXXXX'
const TEAM_ID = 'XXXXXXXXXXX'

const TWENTY_FOUR_HOURS = 1000 * 60 * 60 * 24;
const privateKey = fs.readFileSync("keys/AuthKey.p8").toString();

const generateToken = () => {
  var now = new Date();
  var tomorrow = new Date(now.getTime() + TWENTY_FOUR_HOURS);
  token = jwt.sign({
    'iss': TEAM_ID,
    'iat': Math.floor(now / 1000),
    'exp': Math.floor(tomorrow / 1000)
  }, privateKey, { algorithm: 'ES256', 'keyid': APNS_KEY_ID})
  console.log('Apple token generated', token)
  return token
}
generateToken()

要测试：

curl -X GET \
  'https://api.music.apple.com/v1/catalog/us/search?term=drake&types=songs&limit=1' \
  -H 'Authorization: Bearer eyJh...'
