HarmonyOS鸿蒙Next中ArkTS调起相机扫描二维码

api9 Stage模型下ArkTS唤起相机

//方案2 import abilityAccessCtrl from ‘@ohos.abilityAccessCtrl’; import common from ‘@ohos.app.ability.common’; //测试中

//方案1 // import camera from ‘@ohos.multimedia.camera’; // 失败//@ohos.multimedia.camera是系统接口，只有系统应用能调用

@Entry @Component struct Index {

build() { Row() { Column() {

    Text('调用相机')

        this.takePhoto();
      })
