从电容器3开始，应用程序信息从设备插件移动到应用程序插件。
首先安装插件

npm install @capacitor/app
npx cap sync

现在，您可以在应用程序中使用它

import { App } from '@capacitor/app';

const info = await App.getInfo();
console.log(info);

对于电容器2和更早版本，您可以使用设备插件，getInfo函数包含appId

import { Plugins } from '@capacitor/core';

const { Device } = Plugins;

const info = await Device.getInfo();
console.log(info);

// Example output:
