手机浏览器扫描二维码时报错：cordova_not_avaliable，但是打包成app，扫描没有问题
import {BarcodeScanner } from "ionic-native"; BarcodeScanner.scan().then((result) => { alert(result.text); }, (err) => { alert(err); });
The problem description is not clear
The QR code scanning function in this project is related to the cordova.js file and can only be run on a device or simulator
You use the cordova或者ionic native plug-in to scan the QR code, which of course can only be called in the packaged app!
