User API Tutorial

Run the example

1. Install and run the device gateway
2. Download the Node.js client library
3. Copy the root certificate of the gateway to your working directory. As default, the certificate(ca.crt) resides in cert of the installation directory.

4. Change the gateway and the device information in example/user/test/test.js as needed.

    // the path of the root certificate
    const GATEWAY_CA_FILE = '../../../../cert/gateway/ca.crt';
   
    // the address of the gateway
    const GATEWAY_IP = '192.168.0.2';
    const GATEWAY_PORT = 4000;
   
    // the ip address of the target device
    const DEVICE_IP = '192.168.0.110';
    const DEVICE_PORT = 51211;
    const USE_SSL = false;
   

5. Install packages.

    npm install
   

6. Run.

    cd example/user/test
    node test.js
   

1. Connect to the gateway and the device

The example assumes you use the device gateway. For the master gateway or other connection options, refer to the Connect or ConnectMaster examples.

  var rootCa = fs.readFileSync(GATEWAY_CA_FILE);
  var sslCreds = grpc.credentials.createSsl(rootCa);
  var addr = `${GATEWAY_IP}:${GATEWAY_PORT}`;

  connect.initClient(addr, sslCreds);

  var deviceID = await connect.connectToDevice(DEVICE_IP, DEVICE_PORT, USE_SSL);

2. Change the auth configuration

To test the authentication modes of the test user, AuthConfig.usePrivateAuth will be enabled.

  const origConfig = await auth.getConfig(devID);

  // Enable private authentication for test
  var testConfig = origConfig.cloneMessage();
  testConfig.setUseprivateauth(true);

  await auth.setConfig(devID, testConfig);

3. Enroll users

Enroll a test user and set the authentication modes. For brevity, the example sets only the simple authentication modes. You can test all the modes by changing these values.

  const newUserID = util.format('%d', Date.now());
  var newUserHdr = new user.userMessage.UserHdr();
  newUserHdr.setId(newUserID);

  var newUser = new user.userMessage.UserInfo();
  newUser.setHdr(newUserHdr);

  var newUserSetting = new user.userMessage.UserSetting();
  if(devType == device.deviceMessage.Type.FACESTATION_F2 || devType == device.deviceMessage.Type.FACESTATION_F2_FP) {
    newUserSetting.setCardauthextmode(auth.authMessage.AuthMode.AUTH_EXT_MODE_CARD_ONLY);
    newUserSetting.setFingerauthextmode(auth.authMessage.AuthMode.AUTH_EXT_MODE_FINGERPRINT_ONLY);
    newUserSetting.setFaceauthextmode(auth.authMessage.AuthMode.AUTH_EXT_MODE_FACE_ONLY);
  } else {
    newUserSetting.setCardauthmode(auth.authMessage.AuthMode.AUTH_MODE_CARD_ONLY);
    newUserSetting.setBiometricauthmode(auth.authMessage.AuthMode.AUTH_MODE_BIOMETRIC_ONLY);
  }
  newUser.setSetting(newUserSetting);

  await user.enroll(devID, [newUser]);

4. Add credentials to users

Add cards, fingerprints, or faces to the test user. To know the supported credentials of each device, you can use Device.GetCapabilityInfo. For added credentials, check whether you can authenticate them on the device.

  const capInfo = await device.getCapabilityInfo(deviceID);

  if(capInfo.cardsupported) {
    await testCard.test(deviceID, testUserID);
  } 

  if(capInfo.fingersupported) {
    await testFinger.test(deviceID, testUserID);
  }    

  if(capInfo.facesupported) {
    await testFace.test(deviceID, testUserID);
  }   

  const cardData = await card.scan(devID);
  var userCard = new user.userMessage.UserCard();
  userCard.setUserid(userID);
  userCard.addCards(cardData.getCsncarddata(), 0);

  await user.setCard(devID, [userCard]);
  await menu.pressEnter('>> Try to authenticate the enrolled card. And, press ENTER to end the test.\n');

  var fingerData = new finger.fingerMessage.FingerData();

  var templateData = await finger.scan(devID);
  fingerData.addTemplates(templateData, 0);

  templateData = await finger.scan(devID);
  fingerData.addTemplates(templateData, 1);

  var userFinger = new user.userMessage.UserFinger();
  userFinger.setUserid(userID);
  userFinger.addFingers(fingerData, 0);

  await user.setFinger(devID, [userFinger]);
  await menu.pressEnter('>> Try to authenticate the enrolled finger. And, press ENTER to end the test.\n');

  var faceData = await face.scan(devID, face.faceMessage.FaceEnrollThreshold.BS2_FACE_ENROLL_THRESHOLD_DEFAULT);

  var userFace = new user.userMessage.UserFace();
  userFace.setUserid(userID);
  userFace.addFaces(faceData, 0);

  await user.setFace(devID, [userFace]);
  await menu.pressEnter('>> Try to authenticate the enrolled face. And, press ENTER to end the test.\n');

5. Test the authentication modes

You can set the authentication modes of a device using AuthConfig.

At this step, AuthConfig.usePrivateAuth is set to false. In other words, these authentication modes will be applied to all the users.

  const config = new auth.authMessage.AuthConfig();
  config.setMatchtimeout(10);
  config.setAuthtimeout(15);
  config.setUseprivateauth(false);

  if(devType == device.deviceMessage.Type.FACESTATION_F2 || devType == device.deviceMessage.Type.FACESTATION_F2_FP) {
    let authSched = new auth.authMessage.AuthSchedule();
    authSched.setMode(auth.authMessage.AuthMode.AUTH_EXT_MODE_CARD_ONLY); // Card Only
    authSched.setScheduleid(1); // Always
    config.addAuthschedules(authSched, 0);

    authSched = new auth.authMessage.AuthSchedule();
    authSched.setMode(auth.authMessage.AuthMode.AUTH_EXT_MODE_FACE_ONLY); // Face Only
    authSched.setScheduleid(1); // Always
    config.addAuthschedules(authSched, 1);

    authSched = new auth.authMessage.AuthSchedule();
    authSched.setMode(auth.authMessage.AuthMode.AUTH_EXT_MODE_FINGERPRINT_ONLY); // Fingerprint Only
    authSched.setScheduleid(1); // Always
    config.addAuthschedules(authSched, 2);
  } else {
    let authSched = new auth.authMessage.AuthSchedule();
    authSched.setMode(auth.authMessage.AuthMode.AUTH_MODE_CARD_ONLY); // Card Only
    authSched.setScheduleid(1); // Always
    config.addAuthschedules(authSched, 0);

    authSched = new auth.authMessage.AuthSchedule();
    authSched.setMode(auth.authMessage.AuthMode.AUTH_MODE_BIOMETRIC_ONLY); // Biometric Only
    authSched.setScheduleid(1); // Always
    config.addAuthschedules(authSched, 1);
  }

  await auth.setConfig(devID, config);

  await menu.pressEnter('>> Try to authenticate card or fingerprint or face. And, press ENTER for the next test.\n');

  config.clearAuthschedulesList();

  if(devType == device.deviceMessage.Type.FACESTATION_F2 || devType == device.deviceMessage.Type.FACESTATION_F2_FP) {
    let authSched = new auth.authMessage.AuthSchedule();
    authSched.setMode(auth.authMessage.AuthMode.AUTH_EXT_MODE_CARD_FACE); // Card + Face
    authSched.setScheduleid(1); // Always
    config.addAuthschedules(authSched, 0);

    authSched = new auth.authMessage.AuthSchedule();
    authSched.setMode(auth.authMessage.AuthMode.AUTH_EXT_MODE_CARD_FINGERPRINT); // Card + Fingerprint
    authSched.setScheduleid(1); // Always
    config.addAuthschedules(authSched, 1);
  } else {
    let authSched = new auth.authMessage.AuthSchedule();
    authSched.setMode(auth.authMessage.AuthMode.AUTH_MODE_CARD_BIOMETRIC); // Card + Biometric
    authSched.setScheduleid(1); // Always
    config.addAuthschedules(authSched, 0);
  }

  await auth.setConfig(devID, config);

  await menu.pressEnter('>> Try to authenticate (card + fingerprint) or (card + face). And, press ENTER to end the test.\n');

6. Get the event logs

You can also subscribe to an event stream for receiving realtime events.

  await event.enableMonitoring(devID);

  sub = event.subscribe(EVENT_QUEUE_SIZE);

  sub.on('data', (event) => {
    console.log('Event: ', event.toObject());
  });

  sub.on('end', () => {
    console.log('Subscription is finished');
  });

  sub.on('error', (err) => {
    if(err.details === 'Cancelled') {
      console.log("Subscription is cancelled");
    } else {
      console.log('Subscription error: ', err);
    }
  })
