android - AWS 登录问题 - 登录期间无法联合令牌 java.lang.RuntimeException：联合令牌时出错。- Android

Question

在 amplifyconfiguration.json 中更改用户池 ID 后，对于现有用户池，我能够成功注册，但在登录时出现此错误。

对于登录，我正在使用 Amplify.Auth.signIn( "*** ", " ", result -> { Log.i("AuthQuickstart", result.isSignInComplete() ? "登录成功："+result.toString( ) : "登录未完成"); if (result.isSignInComplete()) { Toast.makeText(SplashActivity.this,"SignIn",Toast.LENGTH_LONG).show(); } }, 错误 -> Log.e( "AuthQuickstart", error.toString()) ); 这个方法。

得到错误就像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.

如果您登录放大只是为了获取访问令牌，那么还有另一种方法可以获取特定用户池的令牌。您可以使用用户名和密码对用户池进行身份验证，然后您可以请求令牌，如下所示：

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();
}
