User API Tutorial
Run the example
- Install and run the device gateway
- Download the C# client library
- Copy the root certificate of the device gateway to your working directory. As default, the certificate(ca.crt) resides in cert of the installation directory.
- The example uses grpc-dotnet. You can change the example/user/test/test.csproj file as needed.
-
Change the gateway and the device information in example/user/test/Program.cs as needed.
// the path of the root certificate private const string GATEWAY_CA_FILE = "../../../../cert/gateway/ca.crt"; // the address of the gateway private const string GATEWAY_ADDR = "192.168.0.2"; private const int GATEWAY_PORT = 4000; // the ip address of the target device private const string DEVICE_ADDR = "192.168.0.110"; private const int DEVICE_PORT = 51211;
-
Build and run.
cd example/user/test dotnet run
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.
GatewayClient gatewayClient = new GatewayClient();
gatewayClient.Connect(GATEWAY_CA_FILE, GATEWAY_ADDR, GATEWAY_PORT);
var connectInfo = new ConnectInfo{ IPAddr = DEVICE_ADDR, Port = DEVICE_PORT, UseSSL = USE_SSL };
uint devID = userTest.connectSvc.Connect(connectInfo);
2. Change the auth configuration
To test the authentication modes of the test user, AuthConfig.usePrivateAuth will be enabled.
AuthConfig origConfig = authSvc.GetConfig(deviceID);
// Enable private authentication for test
AuthConfig testConfig = origConfig.Clone();
testConfig.UsePrivateAuth = true;
authSvc.SetConfig(deviceID, 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.
string newUserID = string.Format("{0}", DateTimeOffset.UtcNow.ToUnixTimeSeconds());
UserInfo newUser = new UserInfo{ Hdr = new UserHdr{ ID = newUserID } };
if(deviceType == Device.Type.FacestationF2 || deviceType == Device.Type.FacestationF2Fp) {
newUser.Setting = new UserSetting{ CardAuthExtMode = (uint)AuthMode.AuthExtModeCardOnly, FingerAuthExtMode = (uint)AuthMode.AuthExtModeFingerprintOnly, FaceAuthExtMode = (uint)AuthMode.AuthExtModeFaceOnly };
} else {
newUser.Setting = new UserSetting{ CardAuthMode = (uint)AuthMode.CardOnly, BiometricAuthMode = (uint)AuthMode.BiometricOnly };
}
userSvc.Enroll(deviceID, new UserInfo[]{ 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.
CapabilityInfo capInfo = userTest.deviceSvc.GetCapabilityInfo(devID);
if(capInfo.CardSupported) {
new CardTest(userTest.cardSvc, userTest.userSvc).Test(devID, newUserID);
}
if(capInfo.FingerSupported) {
new FingerTest(userTest.fingerSvc, userTest.userSvc).Test(devID, newUserID);
}
if(capInfo.FaceSupported) {
new FaceTest(userTest.faceSvc, userTest.userSvc).Test(devID, newUserID);
}
var cardData = cardSvc.Scan(deviceID);
var userCard = new UserCard{ UserID = userID };
userCard.Cards.Add( cardData.CSNCardData );
userSvc.SetCard(deviceID, new UserCard[]{ userCard });
KeyInput.PressEnter(">> Try to authenticate the enrolled card. And, press ENTER to end the test." + Environment.NewLine);
var templateData = new ByteString[NUM_OF_TEMPLATE];
for(int i = 0; i < NUM_OF_TEMPLATE; i++) {
templateData[i] = fingerSvc.Scan(deviceID, TemplateFormat.Suprema, QUALITY_THRESHOLD);
}
var fingerData = new FingerData();
fingerData.Templates.AddRange(templateData);
var userFinger = new UserFinger{ UserID = userID };
userFinger.Fingers.Add( fingerData );
userSvc.SetFinger(deviceID, new UserFinger[]{ userFinger });
KeyInput.PressEnter(">> Try to authenticate the enrolled finger. And, press ENTER to end the test." + Environment.NewLine);
var faceData = faceSvc.Scan(deviceID, FaceEnrollThreshold.Bs2FaceEnrollThresholdDefault);
var userFace = new UserFace{ UserID = userID };
userFace.Faces.Add( faceData );
userSvc.SetFace(deviceID, new UserFace[]{ userFace });
KeyInput.PressEnter(">> Try to authenticate the enrolled face. And, press ENTER to end the test." + Environment.NewLine);
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.
AuthConfig config = new AuthConfig{ MatchTimeout = 10, AuthTimeout = 15 };
if(deviceType == Device.Type.FacestationF2 || deviceType == Device.Type.FacestationF2Fp) {
config.AuthSchedules.Add(new AuthSchedule{ Mode = AuthMode.AuthExtModeCardOnly, ScheduleID = 1 }); // Card Only, Always
config.AuthSchedules.Add(new AuthSchedule{ Mode = AuthMode.AuthExtModeFingerprintOnly, ScheduleID = 1 }); // Fingerprint Only, Always
config.AuthSchedules.Add(new AuthSchedule{ Mode = AuthMode.AuthExtModeFaceOnly, ScheduleID = 1 }); // Face Only, Always
} else {
config.AuthSchedules.Add(new AuthSchedule{ Mode = AuthMode.CardOnly, ScheduleID = 1 }); // Card Only, Always
config.AuthSchedules.Add(new AuthSchedule{ Mode = AuthMode.BiometricOnly, ScheduleID = 1 }); // Biometric Only, Always
}
authSvc.SetConfig(deviceID, config);
KeyInput.PressEnter(">> Try to authenticate card or fingerprint or face. And, press ENTER for the next test." + Environment.NewLine);
config.AuthSchedules.Clear();
if(deviceType == Device.Type.FacestationF2 || deviceType == Device.Type.FacestationF2Fp) {
config.AuthSchedules.Add(new AuthSchedule{ Mode = AuthMode.AuthExtModeCardFace, ScheduleID = 1 }); // Card + Face, Always
config.AuthSchedules.Add(new AuthSchedule{ Mode = AuthMode.AuthExtModeCardFingerprint, ScheduleID = 1 }); // Card + Fingerprint, Always
} else {
config.AuthSchedules.Add(new AuthSchedule{ Mode = AuthMode.CardBiometric, ScheduleID = 1 }); // Card + Biometric, Always
}
authSvc.SetConfig(deviceID, config);
KeyInput.PressEnter(">> Try to authenticate (card + fingerprint) or (card + face). And, press ENTER for the next test." + Environment.NewLine);
6. Get the event logs
You can also subscribe to an event stream for receiving realtime events.
var enableRequest = new EnableMonitoringRequest{ DeviceID = deviceID };
eventClient.EnableMonitoring(enableRequest);
var subscribeRequest = new SubscribeRealtimeLogRequest{ DeviceIDs = {deviceID}, QueueSize = MONITORING_QUEUE_SIZE };
var call = eventClient.SubscribeRealtimeLog(subscribeRequest);
cancellationTokenSource = new CancellationTokenSource();
ReceiveEvents(this, call.ResponseStream, cancellationTokenSource.Token);
static async void ReceiveEvents(EventSvc svc, IAsyncStreamReader<EventLog> stream, CancellationToken token) {
while(await stream.MoveNext(token)) {
var eventLog = stream.Current;
if(svc.callback != null) {
svc.callback(eventLog);
}
}
}
