HarmonyOS 在申请相机权限拒绝后仍能打开相机

使用cameraPicker的话不需要申请权限即可使用

import { BusinessError } from '@ohos.base';

@Entry
@Component
struct Permission_cameraPicker {
  mContext = getContext(this) as common.Context;

  async Permission_cameraPicker_demo() {
    try {
      let pickerProfile: picker.PickerProfile = { cameraPosition: camera.CameraPosition.CAMERA_POSITION_BACK };
      let pickerResult: picker.PickerResult =
        await picker.pick(this.mContext, [picker.PickerMediaType.PHOTO, picker.PickerMediaType.VIDEO], pickerProfile);
      console.log("the pick pickerResult is:" + JSON.stringify(pickerResult));
    } catch (error) {
      let err = error as BusinessError;
      console.error(`the pick call failed. error code: ${err.code}`);
    }
  }

  @State message: string = 'Hello World';

  build() {
    Row() {
      Column() {
        Button(this.message).onClick(() => {
          this.Permission_cameraPicker_demo()
        })
      }.width('100%')
    }.height('100%')
  }
}
