AWS Cognito - 如何从令牌对象获取用户组

Question

登录后，我可以在控制台返回的用户数据对象中看到用户分配的用户池组。我尝试将组分配给变量的所有尝试都失败了。我缺少什么？我可以轻松获取 client_id、JWT 和属性。

对象路径：

let userGroup = user.signInUserSession.accessToken.payload.cognito.groups[0];

但是，这有效：

user.signInUserSession.accessToken.payload.client_id;

对象的这一部分看起来像这样。我可以检索令牌、用户名，几乎任何内容，但组除外。

signInUserSession: CognitoUserSession
    accessToken: CognitoAccessToken
        jwtToken: ...
        payload:
            auth_time: 1539824552
            client_id: "5u7o1o1...."
            cognito:groups: Array(1)
                0: "admin-full"
                length: 1
        ... more properties here...
        token_use: "access"
        username: "me"

我正在使用 Angular 6 和 AWS-Amplify，但我怀疑这是否重要。我的部分代码：

constructor(
    private amplifyService: AmplifyService,
  ) {}

this.amplifyService.auth().currentAuthenticatedUser()
      .then(user => {
         console.log('user data in checkLogin: ', user); // The whole object.
         console.log('user token in checkLogin: ', user.signInUserSession.accessToken.jwtToken); // Retrieves the token.

我的整个会话对象以供澄清：

Answer 1

该组位于会话对象和 idToken 有效负载中，如下所示。
如果您的用户不在组中，则该组不存在。 您应该能够像

accessToken.payload['cognito:groups'];

一样访问它

我碰巧有一个可供组中用户使用的认知会话对象，它显示所有令牌及其所有有效负载。 以及当你获取用户属性时你会得到什么。

Answer 2

如果有人正在使用 Amplify

Auth.currentAuthenticatedUser()
.then(data => console.log(data.signInUserSession.accessToken.payload['cognito:groups']));

Answer 3

public signIn(user: IUser): Promise<any> {
    return Auth.signIn(user.email, user.password)
    .then((data) => {    console.log(data.signInUserSession.accessToken.payload['cognito:groups'][0]);
        this.authenticationSubject.next(true);
    }).catch((e)=>{
 throw e;
    });
  }

Answer 4

Auth.currentAuthenticatedUser()

在 v6 中已弃用。这是我在 v6 中的做法。
