如何使用Amazon Cognito Logout端点?

Jay*_*dha 7 logout amazon-cognito aws-cognito

我在我的应用程序中使用AWS Cognito.

在注销时,我正在调用Logout Endpoint.

但在注销后,我仍然可以使用旧的刷新令牌生成id-tokens.

这意味着我的注销端点不再工作.我正在我的本地存储中保存令牌.在进行注销时,我正在手动清除存储.

我的问题是:如何正确使用AWS Cognito的注销机制?

我不确定你使用的是哪个框架,但我使用的是 Angular。不幸的是,使用 AWS Cognito 的方法有多种,而且文档也不清楚。这是我的身份验证服务的实现(使用 Angular):

- 注意 1 - 使用此登录方法 - 一旦您将用户重定向到注销 URL - 本地主机会自动刷新并且令牌将被删除。

- 注 2 - 您也可以通过调用手动执行此操作: 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'])
  }

}
