HarmonyOS 鸿蒙Next 口令防截屏怎么实现

在需要保护的Page页面调用setWindowPrivacyMode禁止截屏/录屏。
 

import { router, window } from '[@kit](/user/kit).ArkUI';



[@Entry](/user/Entry)

[@Component](/user/Component)

struct Index {

  [@State](/user/State) message: string = 'Hello World';



  onPageShow(): void {

    window.getLastWindow(getContext(this)).then((windowStage: window.Window) => {

      windowStage.setWindowPrivacyMode(true);

    });

  }

  onPageHide(): void {

    window.getLastWindow(getContext(this)).then((windowStage: window.Window) => {

      windowStage.setWindowPrivacyMode(false);

    });

  }

  build() {

    Row() {

      Column() {

        Text(this.message)

          .fontSize(50)

          .fontWeight(FontWeight.Bold)

        Button('click to start Succ Page')

          .onClick(async () => {

            router.pushUrl({ url: 'pages/loginSuccPage' })

          })

      }

      .width('100%')

    }

    .height('100%')

  }

}
