如何实现防截屏功能

Answer 1

setWindowPrivacyMode设置窗口是否为隐私模式，设置为隐私模式的窗口，窗口内容将无法被截屏或录屏。此接口可用于禁止截屏/录屏的场景。具体可参考示例代码：

import { BusinessError } from '@kit.BasicServicesKit'; 
import { window } from '@kit.ArkUI'; 
 
let isPrivacyMode: boolean = true; 
let windowClass: window.Window = window.findWindow("test"); 
try { 
  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)); 
}
