测试遇到的问题：
1 在首页面执行可以，弹出层和其他页面，这边测试发现没通，还在处理中
2 自定义基座需要配置相对应的权限，不然也会出现读卡数据错误，请稍后再试
第一步创建公共文件nfc.js
var NfcAdapter;
export default {
// 初始化NFC
NFCInit() {
try {
let main2 = plus.android.runtimeMainActivity();
let Intent = plus.android.importClass('android.content.Intent');
let Activity = plus.android.importClass('android.app.Activity');
let PendingIntent = plus.android.importClass('android.app.PendingIntent');
let IntentFilter2 = plus.android.importClass('android.content.IntentFilter');
NfcAdapter = plus.android.importClass('android.nfc.NfcAdapter');
let _nfcAdapter = NfcAdapter.getDefaultAdapter(main2);
let ndef = new IntentFilter2('android.nfc.action.NDEF_DISCOVERED');
let tag = new IntentFilter2('android.nfc.action.TAG_DISCOVERED');
let tech = new IntentFilter2('android.nfc.action.TECH_DISCOVERED');
let intentFiltersArray = [ndef, tag, tech];
let techListsArray = [
['android.nfc.tech.Ndef'],
['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']
];
let _intent = new Intent(main2, main2.getClass());
_intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
let pendingIntent = PendingIntent.getActivity(main2, 0, _intent, 0);
if (_nfcAdapter == null) {} else if (_nfcAdapter.isEnabled() == false) {} else {
_nfcAdapter.enableForegroundDispatch(main2, pendingIntent, IntentFilter2, techListsArray);
}
} catch (e) {}
},
// 读取NFC上的数据
NFCReadUID() {
let main3 = plus.android.runtimeMainActivity();
let _intent = main3.getIntent();
let _action = _intent.getAction();
if (NfcAdapter.ACTION_NDEF_DISCOVERED == _action || NfcAdapter.ACTION_TAG_DISCOVERED == _action ||
NfcAdapter.ACTION_TECH_DISCOVERED == _action) {
let Tag = plus.android.importClass('android.nfc.Tag');
let tagFromIntent = _intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);
let bind_code = _intent.getByteArrayExtra(NfcAdapter.EXTRA_ID);
bind_code = this.byteArrayToHexString(bind_code);
uni.$emit('nfcCode', {
code: bind_code
})
}
},
// 将转大写格式
byteArrayToHexString(inarray) {
let i, j, inn;
let hex = ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "A", "B", "C", "D", "E", "F"];
let out = "";
for (j = 0; j < inarray.length; ++j) {
inn = inarray[j] & 0xff;
i = (inn >>> 4) & 0x0f;
out += hex[i];
i = inn & 0x0f;
out += hex[i];
}
return out;
},
}
第二步，在页面引入上面NFC.js文件，并且调用对应的方法
<script>
import nfcFun from "../../static/nfc.js"; // 当前地址根据你存放NFC的位置进行引入即可
export default {
data() {
return {
cardNumber: ''
}
},
onLoad() {
// 接收nfc的值
uni.$on('nfcCode',(data)=>{
const { code } = data;
if (code) this.cardNumber = parseInt(code, 16); // 因为我这边数据是十六进制，所以需要加进行转换
nfcFun.NFCInit(); // 每次刷完后，需要重新初始化下，不然只能刷一次
})
},
onHide() {
nfcFun.NFCReadUID();
},
created() {
nfcFun.NFCInit();
},
onUnload() {
uni.$off('nfcCode') //移除监听nfc
}
}
</script>

注意点： 在调试时，选择标准基座运行即可。
如果需要使用自定义基座，那么需要配置相对应的权限配置。
如下： 偷个懒，没有去仔细区分，各位可自行去掉多余的权限。
"android" : {
"permissions" : [
"<uses-permission android:name=\"android.permission.CHANGE_NETWORK_STATE\"/>",
"<uses-permission android:name=\"android.permission.MOUNT_UNMOUNT_FILESYSTEMS\"/>",
"<uses-permission android:name=\"android.permission.VIBRATE\"/>",
"<uses-permission android:name=\"android.permission.READ_LOGS\"/>",
"<uses-permission android:name=\"android.permission.ACCESS_WIFI_STATE\"/>",
"<uses-feature android:name=\"android.hardware.camera.autofocus\"/>",
"<uses-permission android:name=\"android.permission.ACCESS_NETWORK_STATE\"/>",
"<uses-permission android:name=\"android.permission.CAMERA\"/>",
"<uses-permission android:name=\"android.permission.GET_ACCOUNTS\"/>",
"<uses-permission android:name=\"android.permission.READ_PHONE_STATE\"/>",
"<uses-permission android:name=\"android.permission.CHANGE_WIFI_STATE\"/>",
"<uses-permission android:name=\"android.permission.WAKE_LOCK\"/>",
"<uses-permission android:name=\"android.permission.FLASHLIGHT\"/>",

"<uses-permission android:name=\"android.permission.WRITE_SETTINGS\"/>",
"<uses-permission android:name=\"android.permission.GET_TASKS\"/>",
"<uses-permission android:name=\"android.permission.REORDER_TASKS\"/>",
"<uses-permission android:name=\"android.permission.SYSTEM_ALERT_WINDOW\"/>",
"<uses-permission android:name=\"android.permission.SYSTEM_OVERLAY_WINDOW\"/>",
"<uses-permission android:name=\"android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS\"/>",

"<uses-permission android:name=\"android.permission.RECEIVE_BOOT_COMPLETED\"/>",
"<uses-permission android:name=\"android.permission.PACKAGE_USAGE_STATS\"/>",
"<uses-permission android:name=\"android.permission.NFC\"/>",
"<uses-feature android:name=\"android.hardware.nfc\" android:required=\"true\"/>"
],
"abiFilters" : [ "armeabi-v7a", "arm64-v8a", "x86" ]
},
