angular.js - 手机浏览器扫描二维码报错

Question

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);
        });

Answer 1

The problem description is not clear

Answer 2

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

Answer 3

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!
