HarmonyOS 请问拍照实现方案中cameraShootingCase方法传参是传什么？

参数有baseContext: common.BaseContext，surfaceId: string，common.BaseContext为需要保存状态的UIAbility所对应的context。参考链接：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-inner-application-uiabilitycontext-V5

参考代码写法：

camera.getCameraManager(getContext(this) as common.UIAbilityContext);  

surfaceId为XComponent的surfaceId，起到绑定相应XComponent的作用，代码参考：

private mXComponentController: XComponentController = new XComponentController; this.mXComponentController.setXComponentSurfaceSize({ surfaceWidth: 1920, surfaceHeight: 1080 }); 
let surfaceId = this.mXComponentController.getXComponentSurfaceId()
