AWS Cognito-如何从令牌对象获取用户的组 [英] AWS Cognito - How To Get User's Group From Token Object

问题描述

登录后，我可以在控制台的返回的用户数据对象中看到用户分配的用户池组.我试图将该组分配给变量的所有操作均失败.我想念什么?我可以轻松获取client_id，JWT和属性.

I can see the user's assigned User Pool group in the returned user data object in the console after logging in. Everything I've tried to assign the group to a variable has failed. What am I missing? I can easily get the client_id, JWT's, and attributes.

对象路径:

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

但是，这可行:

user.signInUserSession.accessToken.payload.client_id;

对象的此部分如下所示.我可以检索令牌，用户名以及除组之外的几乎所有内容.

This section of the object looks like this. I can retrieve the token, the user name, almost anything but groups.

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，但我怀疑这很重要.我的部分代码:

I'm using Angular 6 and AWS-Amplify but I doubt that matters. Part of my code:

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.

我的整个会话对象需要澄清:

My whole session object for clarification:

推荐答案

该组位于会话对象和idToken有效载荷中，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'];

The group is in the session Object and in the idToken Payload as seen below.
The group is not there if your user is not in a group. You should be able to access it like accessToken.payload['cognito:groups'];

我碰巧有一个供小组中的用户使用的Cognito会话对象，其中显示了所有令牌及其所有有效载荷.以及获得用户属性时获得的内容.

I happen to have a cognito session object handy for a user in a group, which shows all tokens and all their payloads. As well as what you get when you get the user attributes.
