使用nativescript-nfc插件创建Nativescript-vue应用。我有以下内容:

<script>
const applicationSettings = require("application-settings");

var Nfc = require("nativescript-nfc").Nfc;

export default {
  methods: {
    onButtonTap() {
      if (this.nfcEnabled) {
        this.nfc
          .setOnNdefDiscoveredListener(
            data => {
              if (data.message) {
                data.message.forEach(record => {
                  console.log("Scanner:NdefListener=" + record.payloadAsString);
                  this.nfcLastTagRead = record.payloadAsString;

                  if (this.nfcLastTagRead) {
                    let fob = fobService.findFob(this.this.nfcLastTagRead);
                    console.log(
                      "found "this.this.nfcLastTagRead);

                  } else {
                    console.log("nfcLastTagRead is falsy");
                  }
                });
              }
            },
            {
              stopAfterFirstRead: true

            }
          )
          .then(() => {
            console.log("Scanner:setStartNdefListener added");
          })
          .catch(err => console.err(err));
      } else {
        console.log("NFC is not enabled or available on this device");
      }
    },
    lookupId: function() {
      console.log("in the lookupId()");
    }
  },
  data() {
    return {
      nfc: null,
      nfcEnabled: false,
      nfcLastTagRead: ""
    };
  },

  beforeMount: function() {
    const uuid = applicationSettings.getString("deviceId");

    // instantiate the plugin
    this.nfc = new Nfc();

    this.nfc
      .available()
      .then(available => {
        console.log("Scanner:available=" + available);
        return this.nfc.enabled();
      })
      .then(enabled => {
        console.log("Scanner:enabled=" + enabled);
        this.nfcEnabled = true;
      })
      .catch(err => console.err(err));


  }
};
</script>   

在启动时并单击click()时运行此命令,我在控制台中得到以下内容:

  

控制台日志文件:///app/bundle.js:377:18:   \ 134 ^ [[32m'Scanner:available = true'\ 134 ^ [[39m CONSOLE LOG   文件:///app/bundle.js:380:18:   \ 134 ^ [[32m'Scanner:enabled = true'\ 134 ^ [[39m HTHangEventCreate:   HangTracing已禁用。不创建新事件。

我看到NFC插件确实可以工作,但是在消息出现后似乎停止了。在搜索此特定错误消息时,所有结果都指向Firebase的插件问题,但是我没有在项目中使用它,也没有任何依赖项。
