Problema di accesso ad AWS: impossibile federare i token durante l'accesso java.lang.RuntimeException: errore nella federazione del token.- Android

Question

Dopo aver modificato l'ID del pool di utenti in amplifyconfiguration.json Per il pool di utenti esistente sono in grado di registrarmi correttamente, ma durante l'accesso ricevo questo errore.

per accedere sto utilizzando Amplify.Auth.signIn ("*** ", " ", result -> {Log.i ("AuthQuickstart", result.isSignInComplete ()? "Sign in Successed:" + result.toString ( ): "Accesso non completato"); if (result.isSignInComplete ()) {Toast.makeText (SplashActivity.this, "SignIn", Toast.LENGTH_LONG) .show ();}}, errore -> Log.e ( "AuthQuickstart", error.toString ())); questo mettod.

ottenere l'errore è come W/AWSMobileClient: Failed to federate tokens during sign-in java.lang.RuntimeException: Error in federating the token. at com.amazonaws.mobile.client.AWSMobileClient$10.run(AWSMobileClient.java:1716) at com.amazonaws.mobile.client.internal.InternalCallback.await(InternalCallback.java:115) at com.amazonaws.mobile.client.AWSMobileClient.federatedSignInWithoutAssigningState(AWSMobileClient.java:1644) at com.amazonaws.mobile.client.AWSMobileClient$6$1.onSuccess(AWSMobileClient.java:1191) at com.amazonaws.mobileconnectors.cognitoidentityprovider.CognitoUser.getSession(CognitoUser.java:1020) at com.amazonaws.mobile.client.AWSMobileClient$6.run(AWSMobileClient.java:1176) at com.amazonaws.mobile.client.internal.InternalCallback$1.run(InternalCallback.java:101) at java.lang.Thread.run(Thread.java:761) Caused by: com.amazonaws.services.cognitoidentity.model.InvalidIdentityPoolConfigurationException: Invalid identity pool configuration.

Se esegui l'accesso per amplificare solo per ottenere il token di accesso, esiste un altro modo per ottenere il token di un pool di utenti specifico. Puoi autenticare il pool di utenti utilizzando nome utente e password e quindi puoi chiedere il token come di seguito:

public class AWSService {

public IdentityManager identityManager ;
public AWSCredentialsProvider credentialsProvider ;
public AWSConfiguration awsConfiguration;


public AWSService(Context context) {
    awsConfiguration = new AWSConfiguration(context);
    identityManager = new IdentityManager(context, awsConfiguration);
    identityManager.addSignInProvider(CognitoUserPoolsSignInProvider.class);
    IdentityManager.setDefaultIdentityManager(identityManager);
    credentialsProvider = identityManager.getCredentialsProvider();
}}




public static void getAccessToken(Context context, int requestCode, GetUserPoolTokenListener getUserPoolTokenListener) {


    AWSService awsService=new AWSService(context);

    CognitoUserPool cognitoUserPool=new CognitoUserPool(context,
            awsService.awsConfiguration);

    AuthenticationDetails authDetails = new AuthenticationDetails(PreferenceUtils.getStringPref(context,Constants.USER_NAME), PreferenceUtils.getStringPref(context,Constants.PASSWORD), null);

    final CognitoUser cognitoUser = cognitoUserPool.getUser();

    cognitoUser.initiateUserAuthentication(authDetails, new AuthenticationHandler() {
        @Override
        public void onSuccess(CognitoUserSession userSession, CognitoDevice newDevice) {
            Log.e("aws","onSuccess : "+userSession.getIdToken().getExpiration().getTime());
                        }

        @Override
        public void getAuthenticationDetails(AuthenticationContinuation authenticationContinuation, String userId) {
            Log.e("aws","getAuthenticationDetails : "+authenticationContinuation);
        }

        @Override
        public void getMFACode(MultiFactorAuthenticationContinuation continuation) {
            Log.e("aws","getMFACode : "+continuation);
        }

        @Override
        public void authenticationChallenge(ChallengeContinuation continuation) {
            Log.e("aws","authenticationChallenge : "+continuation);
        }

        @Override
        public void onFailure(Exception exception) {
            Log.e("aws","onFailure : "+exception);
        }
    }, true).run();
}
