导入har

项目中导入提供的开发包 readcardlibrary.har

鸿蒙next的NFC使用配置，请参考官方文档。

需要在EntryAbility 中添加NFC tag相关的监听。

在项目的 module.json5 文件中需要配置NFC的权限

"requestPermissions": [
      {
        "name": "ohos.permission.NFC_TAG",
        "reason": "$string:app_name"
      },
      {
        "name": "ohos.permission.NFC",
        "reason": "$string:app_name"
      },
      {
        "name": "ohos.permission.INTERNET",
        "reason": "$string:app_name"
      },
      {
        "name": "ohos.permission.STORE_PERSISTENT_DATA",
        "reason": "$string:app_name"
      }
    ]

还需要配置NFC的tag类型

"skills": [
          {
            "entities": [
              "entity.system.home"
            ],
            "actions": [
              "action.system.home",
              // add the nfc tag action
              "ohos.nfc.tag.action.TAG_FOUND"
            ],
            "uris": [
              {
                "type":"tag-tech/NfcA"
              },
              {
                "type":"tag-tech/IsoDep"
              },
              {
                "type":"tag-tech/NfcB"
              }
              // Add other technology if neccessary,
              // such as: NfcB/NfcF/NfcV/Ndef/MifareClassic/MifareUL/NdefFormatable
            ]
          }
        ]

在需要NFC读卡的界面使用SDK

// 读卡库
import { ReadCardManager, IdCardData } from 'readcardlibrary'
// NFC相关
import { tag, nfcController } from '@kit.ConnectivityKit';
// 状态码
let StatusCode = ReadCardManager.getInstance().StatusCodeEnum()

设置读卡参数

// 设置参数
ReadCardManager.getInstance().readSetting({
            decodeImageType: "dn1", // dn0: 无照片   dn1: 平台解码照片
            readCardType: 2, // 2：NFC
            saveLog: false, // 是否保存日志文件
            openLocalCache: true, // 是否开启本地缓存
            ipPortArray: [{
              // 云解码服务器配置。
              address: 'yfs4.sfzydq.com',
              port: 9999,
              canUse: true
            }]
          })

// 设置APPID
// 配置读卡 appid （正式商业APPID请联系我司商务分配）
ReadCardManager.getInstance().setAppId("");

接收到NFC TAG 开始读卡

/**
   * 接收到NFC TAG，开始读卡
   * @param tagInfo
   */
  tagNfc(tagInfo: tag.TagInfo): void {
    try {
      console.log("canIUse NFC.Tag : " + canIUse("SystemCapability.Communication.NFC.Tag"));
      if (tagInfo == null || tagInfo == undefined) {
        console.log("no TagInfo to be created, ignore it.");
        return;
      }
      if (tagInfo.technology == null || tagInfo.technology == undefined) {
        console.log("technology is null");
        return;
      }
      let that = this;
      ReadCardManager.getInstance()
        .startReadCard(tagInfo, (code: number, msg: string, value: Object, cardType: number) => {
          let code_msg = "code：" + code + "\n" + "msg：" + msg;
