HarmonyOS 鸿蒙Next 设置不允许录屏的代码是在哪里设置

1、一些页面需要实现防录屏功能，首先需要在module.json5中申请隐私窗口权限

"requestPermissions": [
  {
    "name" : 'ohos.permission.PRIVACY_WINDOW'
  }
],

2、在EntryAbility文件中

let windowClass: window.Window = windowStage.getMainWindowSync();
// 获取应用主窗口
AppStorage.setOrCreate("windowClass",windowClass);
windowStage.loadContent('pages/Index', (err) => {
  if (err.code) {
    hilog.error(0x0000, 'testTag', 'Failed to load the content. Cause: %{public}s', JSON.stringify(err) ?? '');
    return;
  }
  hilog.info(0x0000, 'testTag', 'Succeeded in loading the content.');
});

3、Index文件中

import { window } from '@kit.ArkUI';
import { BusinessError } from '@ohos.base';
@Entry
@Component
struct Index {
  private windowStage = AppStorage.get("windowStage") as window.WindowStage
  private windowClass = AppStorage.get("windowClass") as window.Window
  @State message: string = 'Hello World';
  build() {
    Row() {
      Column() {
        Text('禁止录屏')
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
          .onClick(() => {
            let isPrivacyMode: boolean = true;
            try {
              this.windowClass.setWindowPrivacyMode(isPrivacyMode, (err: BusinessError) => {
                const errCode: number = err.code;
                if (errCode) {
                  console.error('Failed to set the window to privacy mode. Cause:' + JSON.stringify(err));
                  return;
                }
                console.info('Succeeded in setting the window to privacy mode.');
              });
            } catch (exception) {
              console.error('Failed to set the window to privacy mode. Cause:' + JSON.stringify(exception));
            }
          })
        Text('允许录屏')
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
          .onClick(() => {
            let isPrivacyMode: boolean = false;
            try {
              this.windowClass.setWindowPrivacyMode(isPrivacyMode, (err: BusinessError) => {
                const errCode: number = err.code;
                if (errCode) {
                  console.error('Failed to set the window to privacy mode. Cause:' + JSON.stringify(err));
                  return;
                }
                console.info('Succeeded in setting the window to privacy mode.');
              });
            } catch (exception) {
              console.error('Failed to set the window to privacy mode. Cause:' + JSON.stringify(exception));
            }
          })
      }
      .width('100%')
    }
    .height('100%')
  }
}
