java - Cognito用户池: How to use refreshToken to get new accessToken after accessToken gets expired in aws cognito java sdk?

Question

我在基于 scala play 框架的 Web 应用程序中使用 aws cognito 作为用户管理解决方案。我正在使用以下代码登录。

var mIdentityProvider: AWSCognitoIdentityProvider = getAmazonCognitoIdentityClient;

def sessionLogin(userName: String, password: String): AdminInitiateAuthResult = {
val authParams: java.util.Map[String, String] = new java.util.HashMap[String, String]()
    authParams.put("USERNAME", userName)
    authParams.put("PASSWORD", password)
    val authRequest = new AdminInitiateAuthRequest()
      .withAuthFlow(AuthFlowType.ADMIN_NO_SRP_AUTH)
      .withUserPoolId("***")
      .withClientId("***")
      .withAuthParameters(authParams)
    val authResult = mIdentityProvider.adminInitiateAuth(authRequest)
    authResult
}

以上代码从 aws cognito 服务器返回 accessToken、expiresIn、tokenType、refreshToken 和 idToken。根据aws文档，当accessToken过期时，我们可以使用refreshToken来获取新的accessToken或idToken，以便继续用户 session 。但在文档中没有提到如何使用refreshToken来达到此目的。任何有关这方面的帮助将是值得赞赏的。提前致谢。

我自己想出来了。以下是工作代码

def refreshAccessToken(refreshToken: String): AuthenticationResultType = {
    val authParams: java.util.Map[String, String] = new java.util.HashMap[String, String]()
    authParams.put("REFRESH_TOKEN", refreshToken)
    val authRequest = new AdminInitiateAuthRequest()
      .withAuthFlow(AuthFlowType.REFRESH_TOKEN_AUTH)
      .withUserPoolId("***")
      .withClientId("***")
      .withAuthParameters(authParams)
    val authResult = mIdentityProvider.adminInitiateAuth(authRequest)
    val resultType: AuthenticationResultType = authResult.getAuthenticationResult
    resultType
  }
