mobile application keep loading when call to @OAuthSecurity resource

Question

Good day,

I have a mobile application and call to mobileFirstPlatform and then only go to my backend service.

I am not sure my understanding is correct or not, in order to call to my Adapter Resource with @OAuthSecurity, I need to authenticate success with mfp first, then only able to access to that resource.

In my mobileFirst Console, I have configure this as my Scope-Elements Mapping and Mandatory Application Scope:

The following is part of my frontend code in login.component.ts:

ngOnInit() {
      this.mfpAuthenticationService.initEventHandler();
      this.initAuthHandle();
}

  initAuthHandle() {
    this.authSuccessEventSubscription = this.mfpAuthenticationService.authSuccessEvent.subscribe((loginResponse: any) => {
// do something after success login
});

this.authFailureEventSubscription = this.mfpAuthenticationService.authFailureEvent.subscribe((res: any) => {

      console.log('authFailureEvent => ', res);

      if (res.errorCode == WLErrorCodeConstant.ClientSideError.CHALLENGE_HANDLING_CANCELED && this.mfpAuthenticationService.isBiometricAuthenticated()) {

        return;

      } else {

        this.handleLoginError(res);

        this.loginForm.resetForm();

        this.processLogin = false;

      }

    });

    this.authChallengeEventSubscription = this.mfpAuthenticationService.authChallengeEvent.subscribe((res: any) => {

      console.log('authChallengeEvent => ', res);

      let redirectPath = this.sessionService.getSessionStorage(SessionName.REDIRECT_PATH);

      if (redirectPath) {

        console.log('biometric user login error => ', res);

        this.login.password = null;

        this.isLoginButtonClicked = false;

        this.baseService.handleError(res, true);

      } else {

        this.handleLoginError(res);

      }

      this.loginForm.resetForm();

      this.processLogin = false;

    });
}

performLogin() {
this.mfpAuthenticationService.performLogin(this.login.username, this.loginRequest);
}

And this is some code on mfp.auth.service.ts:

initEventHandler() {
        console.log("come mfp.auth.service.ts initEventhandler");
        this.currentEventHandler = '';
        this.userLoginChallengeHandler = null;
        this.userLoginChallengeHandler = WL.Client.createSecurityCheckChallengeHandler('UserAuthentication');
        this.userLoginChallengeHandler.securityCheckName = '';
        this.userLoginChallengeHandler.handleSuccess = (loginSuccess) => {
            console.log("handleSuccess");
            this.isChallenged = false;
            if (this.currentEventHandler != this.eventHandler.success) {
                this.currentLoginGrantType = this.processLoginGrantType;
                //alert("initEventHandler|loginSuccess=\n" + JSON.stringify(loginSuccess));
                console.log("loginSuccess is " + JSON.stringify(loginSuccess));
                this.mfpAuthResponse = {
                    id: loginSuccess.id,
                    accessToken: loginSuccess.user.attributes.access_token,
                    tokenType: loginSuccess.user.attributes.token_type,
                    expiresIn: loginSuccess.user.attributes.expires_in,
                    scope: loginSuccess.user.attributes.scope,
                    clientId: loginSuccess.user.attributes.client_id
                };
            }
            this.currentEventHandler = this.eventHandler.success;
            console.log("handler success, challenged is " + this.isChallenged);
        };

        this.userLoginChallengeHandler.handleFailure = (loginError) => {
            console.log("handleFailure");
            this.isChallenged = false;
            if (this.currentEventHandler != this.eventHandler.failure) {
                this.authFailureEvent.emit(loginError);
            }
            this.currentEventHandler = this.eventHandler.failure;
            console.log("handleFailure, challenged is " + this.isChallenged);
        };

        this.userLoginChallengeHandler.handleChallenge = (challenge) => {
            console.log("handleChallenge " + challenge);
            this.isChallenged = true;
            this.challengeResponseModel = challenge;
            this.authChallengeEvent.emit(challenge);
            this.currentEventHandler = this.eventHandler.challenge;
            console.log("handleChallenge, challenged is " + this.isChallenged);
        };
    }

performLogin(username: string, loginRequest: RequestModel<LoginRequestModel>) {
        console.log("come mfp.auth.service.ts performLogin");
        let performed = false;
        let authRequest = {
            requestHeader: {
                deviceId: this.sessionService.getDeviceId(),
                channelTime: new Date().toString()
            },
            requestBody: loginRequest.requestBody
        }
        this.processLoginGrantType = loginRequest.requestBody.grant_type;

        let authObj = {
            'authorization': environment.authorization,
            'authRequest': JSON.stringify(authRequest),
            'authCode': this.service.getHashMAC(authRequest, this.sessionService.getHashKey()),
            'authUser': username
        };
        console.log("mfp-performLogin|isChallenged1=" + this.isChallenged + "\nauthObj=\n" + JSON.stringify(authObj) + "\n\n");
        if (this.isChallenged) {
            console.log("mfp-performLogin|submitChallengeAnswer=");
            this.userLoginChallengeHandler.submitChallengeAnswer(authObj);
        } else {
            console.log("mfp-performLogin|WLAuthorizationManager.login=");
            WLAuthorizationManager.login(this.securityCheckName, authObj).then(
                () => {
                    console.log("mfp-performLogin|WLAuthorizationManager.login.performed=" + performed + "\nmfpAuthResponse=\n" + JSON.stringify(this.mfpAuthResponse) + "\n\n");
                    if (!performed) {
                        this.ngZone.run(() => {
                            console.log("come emit authSuccessEvent");
                            this.authSuccessEvent.emit(this.mfpAuthResponse);
                        });
                    }
                    performed = true;
                },
                (err) => {
                    console.log("mfp-performLogin|WLAuthorizationManager.login.err=\n\n" + JSON.stringify(err) + "\n");
                    console.log('wllogin err => ', err);
                    this.authFailureEvent.emit(err);
                }
            );
        }
    }

As you can see, from my login.component.ts, i will do ngOnInit() first, and after I key in password and press on login button, it will call the performLogin() method, and continue to call to mfp.auth.servicet.ts performLogin().

In mfp.auth.servicet.ts performLogin(), will call to WLAuthorizationManager.login(this.securityCheckName, authObj) because the this.isChallenged value is false by default.

The login is actually successful, as I able to get those oauth response and able to go into my application, my oauth response is something as follow:

The login is successful, but when I want to click to access to resource that having @OAuthSecurity, then my app will keep loading, and no error show in log. Something is blocking in mfp there.

If I remove the Scope-Element Mapping, and Mandatory Application Scope, then no issue, the request can go in successful.

Thus, I am suspecting something wrong in my configuration, or something wrong in my code logic. Really appreciate your advise and help. I am stuck in this more than 2 weeks.

As my understanding, there are 2 part of authentication on this, 1 is authentication with mfp, and another 1 is authentication with my backend service, which is the UserAuthentication.java, I believe my UserAuthentication.java already success authenticated, maybe something wrong with my authentication part with mfp?

And how can I know I have successful authenticate with mfp ya?

Base on this article, http://mobilefirstplatform.ibmcloud.com/tutorials/ru/foundation/8.0/authentication-and-security/credentials-validation/javascript/ And may I know when the handleChallenge() will be call? and also the handleSuccess().

Kindly let me know if need me to provide more information.
