如何使用Amazon Cognito注销终端?

我在应用程序中使用AWS Cognito。

注销时,我正在呼叫Logout Endpoint

但是在注销后,我仍然能够使用旧的刷新令牌来生成id令牌。

这意味着我的注销端点不再起作用。我将令牌保存在本地存储中,在注销时,我正在手动清除存储。

  

我的问题是:如何正确使用AWS的注销机制   认知吗?

我不确定您使用的是哪个框架,但是我正在使用Angular。不幸的是,使用AWS Cognito的方式多种多样,文档尚不清楚。这是我对Authentication Service的实现(使用Angular):

-注1-使用此登录方法-将用户重定向到注销网址后-本地主机会自动刷新并删除令牌。

-注2-您也可以通过以下方法手动进行操作:this.userPool.getCurrentUser()。signOut()

import { Injectable } from '@angular/core'
import { CognitoUserPool, ICognitoUserPoolData, CognitoUser } from 'amazon-cognito-identity-js'
import { CognitoAuth } from 'amazon-cognito-auth-js'
import { Router } from '@angular/router'

const COGNITO_CONFIGS: ICognitoUserPoolData = {
  UserPoolId: '{INSERT YOUR USER POOL ID}',
  ClientId: '{INSERT YOUR CLIENT ID}',
}

@Injectable()
export class CognitoService {

  userPool: CognitoUserPool
  constructor(
    private router: Router
  ) {
    this.createAuth()
  }

  createAuth(): void {
    // Configuration for Auth instance.
    const  authData = {
      UserPoolId: COGNITO_CONFIGS.UserPoolId,
      ClientId: COGNITO_CONFIGS.ClientId,
      RedirectUriSignIn : '{INSERT YOUR COGNITO REDIRECT URI}',
      RedirectUriSignOut : '{INSERT YOUR COGNITO SIGNOUT URI}',
      AppWebDomain : '{INSERT YOUR AMAZON COGNITO DOMAIN}',
      TokenScopesArray: ['email']
    }

    const  auth: CognitoAuth = new CognitoAuth(authData)
    // Callbacks, you must declare, but can be empty.
    auth.userhandler = {
      onSuccess: function(result) {
      },
      onFailure: function(err) {
      }
    }

    // Provide the url and parseCognitoWebResponse handles parsing it for us.
    const curUrl = window.location.href
    auth.parseCognitoWebResponse(curUrl)
  }

  /**
   * Check's if the user is authenticated - used by the Guard.
   */
  authenticated(): CognitoUser | null {
    this.userPool = new CognitoUserPool(COGNITO_CONFIGS)
    // behind the scene getCurrentUser looks for the user on the local storage.
    return this.userPool.getCurrentUser()
  }

  logout(): void {
    this.router.navigate(['/logout'])
  }

}
