Altersverifikation

Added by Christian Kirsch about 3 years ago

Sehr geehrte Damen und Herren,

vielen Dank für Ihre Arbeiten an der Open eCard API.

Wir möchten in einem Projekt einen Getränkefach mit alkoholischen Getränken an einem Wanderweg aufstellen. Dazu möchten wir eine Altersverifikation zum Öffnen des Faches über den Personalausweis realisieren.
Mein Gedanke ist dies mit einem Rasperry Pi Zero und einem Reinersect USB Lesegerät umzusetzen. Es ist keine Internetverbindung vorhanden.

Ich habe es nun geschafft die jars mit Maven zu compilieren, in mein Eclipse Projekt einzufügen und auf API Elemente zuzugreifen. Ich habe ein org.openecard.ifd.scio.IFD Objekt instanziert und konnte mein kleines Programm ohne Exception ausführen,

Nun versuche ich, eine Kartenerkennung mit Fragmenten des Testprogramms ExecuteRecognition von Thomas Wich zu kompilieren. Anbei der Code:

@package org.avs;

import java.math.BigInteger;

import org.openecard.common.ClientEnv;
import org.openecard.common.interfaces.Environment;
import org.openecard.ifd.scio.IFD;
import org.openecard.recognition.CardRecognitionImpl;

import iso.std.iso_iec._24727.tech.schema.ConnectionHandleType.RecognitionInfo;
import iso.std.iso_iec._24727.tech.schema.EstablishContext;
import iso.std.iso_iec._24727.tech.schema.EstablishContextResponse;
import iso.std.iso_iec._24727.tech.schema.GetStatus;
import iso.std.iso_iec._24727.tech.schema.GetStatusResponse;
import iso.std.iso_iec._24727.tech.schema.IFDStatusType;

public class Loop {

public static void main(String[] args) {
        Loop loop = new Loop();
        loop.recognize();
    }

private void recognize () {
        Environment env = new ClientEnv();
        IFD ifd = new IFD();
        env.setIFD(ifd);
        byte[] ctx;
        // establish context
        EstablishContext eCtx = new EstablishContext();
        EstablishContextResponse eCtxR = ifd.establishContext(eCtx);
        ctx = eCtxR.getContextHandle();
        // get status to see if we can execute the recognition
        GetStatus status = new GetStatus();
        status.setContextHandle(ctx);
        GetStatusResponse statusR = ifd.getStatus(status);

if (statusR.getIFDStatus().size() > 0 && statusR.getIFDStatus().get(0).getSlotStatus().get(0).isCardAvailable()) {
              CardRecognitionImpl recog = new CardRecognitionImpl(env);
            IFDStatusType stat = statusR.getIFDStatus().get(0);
            RecognitionInfo info = recog.recognizeCard(ctx, stat.getIFDName(), BigInteger.ZERO);
            if (info == null) {
            System.out.println("Card not recognized.");
        } else {
            System.out.println(info.getCardType());
        }
    }

Er zeigt mir bei EstablishContextResponse eCtxR = ifd.establishContext(eCtx); folgenden Fehler
The method establishContext(iso.std.iso_iec._24727.tech.schema.EstablishContext) in the type IFD is not applicable for the arguments (iso.std.iso_iec._24727.tech.schema.EstablishContext)

Dies macht für mich keinen Sinn, da eCTX genau das Objekt EstablishContent ist, welches die Methode ifd.establishContext(..) haben möchte. Kann mir hier einer weiterhelfen?

Ich würde mich über eine Antwort freuen!

Christian

Nachtrag:

Es war eine Mehrdeutigkeit, da ich auch die Richclient.jar im Build-Path hatte. Als ich diese entfernt habe, hat es funktioniert.

Mit Hilfe des Richclients habe ich nun eine Klasse entworfen, welche u.a. den CardType erkennen soll. Anbei der Code:

public class Loop implements EventCallback {

    private byte[] contextHandle;

static {
        System.setProperty(org.slf4j.impl.SimpleLogger.DEFAULT_LOG_LEVEL_KEY, "DEBUG");
        LOG = LoggerFactory.getLogger(Loop.class.getName());
    }

/**

    public Loop() throws Exception {

// Set up client environment
        env = new ClientEnv();

        //MessageDispatcher dispatcher = new MessageDispatcher(env);

            WSHelper.checkResult(establishContextResponse);
            contextHandle = establishContextResponse.getContextHandle();
        } catch (WSHelper.WSException ex) {
            LOG.debug("Failed to establish context :" + ex.getMessage());
            //String message = LANG.translationForKey("client.startup.failed.nocontext");
            //throw ex;
        }

public static void main(String[] args) {    
        LOG.info("Starting {} {} ...", AppVersion.getName(), AppVersion.getVersion());
        LOG.debug("Running on {} {} {}.", System.getProperty("os.name"), System.getProperty("os.version"), System.getProperty("os.arch"));

try {
            Loop loop = new Loop();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

@Override
    public void signalEvent(EventType eventType, EventObject eventData) {
        LOG.debug("Event: {}", eventType);

ConnectionHandleType ch = eventData.getHandle();
        if (ch == null) {
            LOG.error("No handle provided in event {}.", eventType);
            return;
        }

String ifdName = ch.getIFDName();
        byte[] ctx = ch.getContextHandle();
        LOG.debug("ConnectionHandle: ifd={}, slot={}, ctx={}", ifdName, ByteUtils.toHexString(ch.getSlotHandle()),
            ByteUtils.toHexString(ctx));
        RecognitionInfo info = ch.getRecognitionInfo();

if (info != null) {
            LOG.debug("RecognitionInfo: {}, {}", info.getCardType(), ByteUtils.toHexString(info.getCardIdentifier()));
        } else {
            LOG.debug("RecognitionInfo: null");
        }
    }

Die Methode signalEvent wird Korrekt von EventHandler aufgerufen, wenn ich das USB Lesegerät einstecke und entferne. Sobald ich jedoch eine Smartcard einlege, zeigt der Logger folgende Meldung:
[SCIO Watcher 0] INFO org.openecard.ifd.scio.wrapper.SingleThreadChannel - Card connected with protocol T=1.

Danach zeigt das Programm keine Funktion mehr. Was mache ich falsch?
