HarmonyOS 鸿蒙Next 输入支付密码时禁止录屏

1.先申请ohos.permission.PRIVACY_WINDOW权限 2.onWindowStageCreate中存

  let windowClass = windowStage.getMainWindowSync()
  globalThis.mainWindow = windowClass

3.设置禁止录屏页面

import window from '@ohos.window'

@Entry

@Component

struct Page32 {

  @State message: string = 'Hello World'

  mainWindow :window.Window = globalThis.mainWindow

  build() {

    Row() {

      Column() {

        Text(this.message)

          .fontSize(50)

          .fontWeight(FontWeight.Bold)

      }

      .width('100%')

    }

    .height('100%')

  }

  onPageShow(){

   this.mainWindow.setWindowPrivacyMode(true)

  }

  onPageHide(){

    this.mainWindow.setWindowPrivacyMode(false)

  }

}

防止App录屏或截屏可以通过@ohos.window的setWindowPrivacyMode将窗口设置为隐私模式，隐私模式下的窗口，窗口内容将无法被截屏或录屏 具体使用可以参考文档：https://developer.huawei.com/consumer/cn/doc/harmonyos-references/js-apis-window-V5#setwindowprivacymode9
