从AWS认知refresh_token结果返回aud

Question

我正在使用AWS认知技术来验证用户。

我使用Kosjs创建了一个服务器，并使用Kosjs库来验证用户是否有有效的id_tokens。

koa-jwt期望和属性位于id_token中，该属性最初存在于AWS id_token返回的id_token中。

但是，当我使用刷新令牌获取新令牌时，新令牌包含client_id而不是aud。

正因为如此，koa不再验证id_token。

有什么方法可以从AWS公司获得一致的结果吗？

这是登录后的示例id_token：

​

{
  "sub": "1Xfe6c44-XXXX-4cbf-9fb2-2778a1b0e5be",
  "email_verified": true,
  "iss": "https://cognito-idp.ap-northeast-1.amazonaws.com/ap-northeast-1_xxxOUKTJu",
  "phone_number_verified": true,
  "cognito:username": "oqtz@n.spamtrap.co",
  "given_name": "Some1",
  "aud": "xxxxf9f0lmr1q6ni2c09umdds",
  "event_id": "9cf03730-xxxx-11e9-a89f-67080ff7c936",
  "token_use": "id",
  "auth_time": 1546931916,
  "phone_number": "+16806666986",
  "exp": 1546935516,
  "iat": 1546931916,
  "family_name": "Some2",
  "email": "oqtz@n.spamtrap.co"
}

这是由id_token返回的示例refresh_token：

​

{
  "sub": "16fe6c44-xxxx-xxxx-9fb2-2778a1b0e5be",
  "event_id": "9cf03730-xxxx-xxxx-a89f-67080ff7c936",
  "token_use": "access",
  "scope": "aws.cognito.signin.user.admin",
  "auth_time": 1546931916,
  "iss": "https://cognito-idp.ap-northeast-1.amazonaws.com/ap-northeast-1_xxxxxKTJu",
  "exp": 1546939290,
  "iat": 1546935690,
  "jti": "6fab7b58-xxxx-xxxx-a339-ddb6467e2d4c",
  "client_id": "xxxxx9f0lmr1q6ni2c09umdds",
  "username": "oqtz@n.spamtrap.co"
}

我还没有完全测试刷新功能，但通过在koa上遵循本节底部的示例，我获得了基础知识。

const { koaJwtSecret } = require('jwks-rsa');

    app.use(jwt({   
        secret: <any> koaJwtSecret({
            jwksUri: `https://cognito-idp.${config.userPoolRegion}.amazonaws.com/${config.userPoolId}/.well-known/jwks.json`,
            cache: true,
            cacheMaxEntries: 5,
            cacheMaxAge: 36000000 ///10 hr 
        }) 
    }));
