Question

我正在使用AWS Cognito对用户进行身份验证。

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

koa-jwt在id_token中期望有一个 aud 属性，该属性最初存在于AWS Cognito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 。

因此，koa-jwt不再验证id_token。

是否可以通过AWS Cognito获得一致的结果？

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refresh_token返回的示例id_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"
}

我还没有对刷新进行全面的测试，但是通过遵循koa-jwt自述文件this section底部的示例，我可以快速地进行基础操作。

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 
        }) 
    }));

从AWS Cognito refresh_token结果返回aud
