用Native.js怎么开发NFC

大家先尝鲜一下，我仅测试读公交卡了。数据可以出来，具体哪些数据有用，需要专业开发者补充完善分享。在此先谢过了。
function test_nfc(){
var main = plus.android.runtimeMainActivity();
var Intent = plus.android.importClass('android.content.Intent');
var Activity = plus.android.importClass('android.app.Activity');
var PendingIntent = plus.android.importClass('android.app.PendingIntent');
var IntentFilter = plus.android.importClass('android.content.IntentFilter');
var NfcAdapter = plus.android.importClass('android.nfc.NfcAdapter');
var nfcAdapter = NfcAdapter.getDefaultAdapter(main);
var intent = new Intent(main, main.getClass());
intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
var pendingIntent = PendingIntent.getActivity(main, 0, intent, 0);
var ndef = new IntentFilter("android.nfc.action.TECH_DISCOVERED");
ndef.addDataType("*/*");
var intentFiltersArray = [ndef];
var techListsArray = [["android.nfc.tech.IsoDep"], ["android.nfc.tech.NfcA"], ["android.nfc.tech.NfcB"], ["android.nfc.tech.NfcF"], ["android.nfc.tech.Nfcf"], ["android.nfc.tech.NfcV"], ["android.nfc.tech.NdefFormatable"], ["android.nfc.tech.MifareClassi"], ["android.nfc.tech.MifareUltralight"]];
document.addEventListener("newintent",
function() {
console.log('newintent');
setTimeout(handle_nfc_data,1000);
}, false);

document.addEventListener("pause", function(e) {
if (nfcAdapter) {
nfcAdapter.disableForegroundDispatch(main);
console.log('pause');
}
}, false);

document.addEventListener("resume", function(e) {
if (nfcAdapter) {
console.log('resume');
nfcAdapter.enableForegroundDispatch(main, pendingIntent, intentFiltersArray, techListsArray);
}
}, false);
nfcAdapter.enableForegroundDispatch(main, pendingIntent, intentFiltersArray, techListsArray);
}

function handle_nfc_data(){
var main = plus.android.runtimeMainActivity();
var runtimeIntent = main.getIntent();
var b = runtimeIntent.getExtras();
plus.android.importClass(b);
var set = b.keySet();
plus.android.importClass(set);
var sb;
var i = set.iterator();
plus.android.importClass(i);
var hasNest = i.hasNext();
var NfcA = plus.android.importClass("android.nfc.tech.NfcA");
var IsoDep = plus.android.importClass("android.nfc.tech.IsoDep");
var Tag = plus.android.importClass("android.nfc.Tag");
while (hasNest) {
var key = i.next();
var v = b.get(key);
if(v instanceof NfcA){
var atqa = v.getAtqa();
var sak = v.getSak();
var tag = g.getTag();
plus.android.importClass(tag);
var techList = tag.getTechList();
console.log('NfcA Atqa=' + atqa + ";Sak=" + sak + ";techList=" + techList);
}else if(v instanceof IsoDep){
var tag = g.getTag();
plus.android.importClass(tag);

}
console.log(key + ';v=' + v);
sb = key + "=" + v + "\n";

console.log('hasNest=' + hasNest);
}
