RespondToAuthChallengeResult.getAuthenticationResult（）返回null

Question

我嘗試使用aws-java-sdk-cognitoidentity通過AWS Cognito來實現身份驗證和方便使用cognitoauth classes 認證工作正常，但當我得到AuthenticationResultType從respondToAuthChallengeResult它返回空爲什麼出現這種情況？

樣品：

AWSCryptoSettings cryptoParams = new AWSCryptoSettings(); 
AWSCognitoSession clientSession = new AWSCognitoSession(
      cryptoParams, "test", "123456", USER_POOL_ID); 

AWSCognitoIdentityProvider provider = AWSCognitoIdentityProviderClientBuilder.standard() 
      .withCredentials(new AWSStaticCredentialsProvider(new AnonymousAWSCredentials())) 
      .withRegion(Regions.EU_WEST_1) 
      .build(); 

InitiateAuthRequest authRequest = new InitiateAuthRequest() 
      .withAuthFlow(AuthFlowType.USER_SRP_AUTH) 
      .withClientId(CLIENT_APP_ID) 
      .withAuthParameters(clientSession.step1()); //step1() return Map<String,String> with parameters for auth in it 


    //Respond to authentication challenge 
    InitiateAuthResult authResult = provider.initiateAuth(authRequest); 
    Map<String, String> params = authResult.getChallengeParameters(); 
    Map<String, String> srpAuthResponses = clientSession.step2(params); //step2() return also Map<String, String> with formatted parameters. 

RespondToAuthChallengeRequest respondToAuthChallengeRequest = new RespondToAuthChallengeRequest() 
      .withChallengeName(authResult.getChallengeName()) 
      .withClientId(CLIENT_APP_ID) 
      .withChallengeResponses(srpAuthResponses); 

RespondToAuthChallengeResult respondToAuthChallengeResult = provider.respondToAuthChallenge(respondToAuthChallengeRequest); 

//debug 
System.out.println(respondToAuthChallengeResult.getChallengeName()); 
System.out.println(respondToAuthChallengeResult.getChallengeParameters()); 
System.out.println(respondToAuthChallengeResult.getAuthenticationResult()); 

AuthenticationResultType authenticationResultType = respondToAuthChallengeResult.getAuthenticationResult(); //there null is retruned; 

輸出從SOUT是：

NEW_PASSWORD_REQUIRED
{userAttributes = { 「電子郵件」： 「username123@example.com」}，requiredAttributes = [] }
null

I請不要正確配置用戶池或代碼中的錯誤？

謝謝。

這看起來像你已通過控制檯或通過AdminCreateUser API創建用戶。正如該州所說，用戶需要create a new password。
