Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@hxa-rn/react-native-capture-protection

v2.4.1-beta.1

Published

🛡️ Prevent and detect screen capture, screenshots and app switcher on HarmonyOS (React Native for OpenHarmony adaptation)

Readme

本项目基于 react-native-capture-protection开发。如果在使用过程中有任何问题,欢迎在AtomGit提交Issue,会及时跟进。

项目介绍

@hxa-rn/react-native-capture-protection 是 react-native-capture-protection 的 React Native 鸿蒙(OpenHarmony)适配包,提供防截屏、防录屏、防应用切换预览及截屏检测事件能力。当前版本:2.4.1-beta.1。

| 鸿蒙适配包版本 | 原始库版本 | 支持 RN 版本 | Autolink | 编译 API 版本 | | ------------ | ---------- | ------------ | -------- | ------------- | | 2.4.1-beta.1 | react-native-capture-protection 2.4.1 | 0.72+ | 是 | API 12+ |

集成指南

npm install @hxa-rn/react-native-capture-protection

本包 harmony.alias 为 react-native-capture-protection:业务代码请从 'react-native-capture-protection' 导入,不要写 '@hxa-rn/react-native-capture-protection'。

peerDependencies:react-native >= 0.72。

如使用版本支持 Autolink 且工程已接入,可跳过手动配置。

说明:本模块需要同时在 C++ 侧和 ETS 侧注册 Package。

1. Overrides RN SDK

在工程根目录 oh-package.json5 添加:

{
  "overrides": {
    "@rnoh/react-native-openharmony": "./react_native_openharmony"
  }
}

2. 引入原生端依赖

打开 entry/oh-package.json5,添加:

"dependencies": {
  "@hxa-rn/react-native-capture-protection": "file:../../node_modules/@hxa-rn/react-native-capture-protection/harmony/capture_protection.har"
}

执行 ohpm install。

3. 配置 CMakeLists

打开 entry/src/main/cpp/CMakeLists.txt,添加:

set(OH_MODULES "${CMAKE_CURRENT_SOURCE_DIR}/../../../oh_modules")

add_subdirectory("${OH_MODULES}/@hxa-rn/react-native-capture-protection/src/main/cpp" ./capture_protection)

target_link_libraries(rnoh_app PUBLIC capture_protection)

4. 注册 Package(C++ 侧)

打开 entry/src/main/cpp/PackageProvider.cpp,添加:

#include "CaptureProtectionPackage.h"

std::vector<std::shared_ptr<Package>> PackageProvider::getPackages(Package::Context ctx) {
    return {
        std::make_shared<CaptureProtectionPackage>(ctx),
    };
}

5. 注册 Package(ETS 侧)

打开 entry/src/main/ets/RNPackagesFactory.ets,添加:

import { CaptureProtectionPackage } from '@hxa-rn/react-native-capture-protection/ts';

export function createRNPackages(ctx: RNPackageContext): RNPackage[] {
  return [
    new CaptureProtectionPackage(ctx),
  ];
}

需在 module.json5 中声明 "ohos.permission.PRIVACY_WINDOW"。

使用说明

import {
  CaptureProtection,
  CaptureEventType,
} from 'react-native-capture-protection';
import type { EmitterSubscription } from 'react-native';

async function setupCaptureProtection() {
  // 开启全部捕获防护(防截屏 + 防录屏 + 防应用切换)
  await CaptureProtection.prevent();

  // 关闭全部捕获防护
  await CaptureProtection.allow();

  // 仅开启防截屏
  await CaptureProtection.prevent({ screenshot: true });

  // 查询防护状态
  const status = await CaptureProtection.protectionStatus();
  console.log(status); // { screenshot: boolean, record: boolean, appSwitcher: boolean }

  // 监听截屏 / 应用切换事件(用完后 removeListener 释放)
  const subscription: EmitterSubscription | undefined =
    CaptureProtection.addListener((eventType: CaptureEventType) => {
      if (eventType === CaptureEventType.CAPTURED) {
        console.log('检测到截屏');
      }
    });
  if (subscription) {
    await CaptureProtection.removeListener(subscription);
  }
}

平台差异:

  • 鸿蒙隐私模式为窗口级统一开关:prevent() 一次开启防截屏/防录屏/防应用切换;allowScreenshot() / allowScreenRecord() 等细分 API 实际会关闭整个隐私模式。
  • isScreenRecording() 鸿蒙无等价公开 API,恒返回 undefined。
  • iOS 自定义文本/图片覆盖层(preventScreenRecordWithText 等)鸿蒙不支持自定义内容,仅开启隐私模式统一蒙层。

官方文档(窗口隐私模式):

鸿蒙无分项独立系统能力;prevent({screenshot|record|appSwitcher}) 均映射为 setWindowPrivacyMode(true),protectionStatus() 三项同值。

  • 窗口级统一开关:通过 window.setWindowPrivacyMode(true/false)(API 9+,官方 API)统一控制截屏/录屏/应用切换防护。
  • 事件监听:addListener 注册 window.on('screenshot') 与 window.on('windowEvent'),分别触发 CAPTURED 与 APP_SWITCHING;RECORDING / END_RECORDING 鸿蒙不发送。
  • 保护状态:protectionStatus() 返回的三项同值(窗口级隐私模式布尔)。

快速验证(运行 Example)

前置条件

| 依赖 | 版本要求 | |------|----------| | Node.js | >= 18 | | DevEco Studio | 5.0+ | | HarmonyOS SDK | API 12+ |

运行步骤

1. 克隆仓库

git clone https://gitcode.com/hxa-rn/react-native-capture-protection.git
cd react-native-capture-protection
git checkout br_rnoh0.72

2. 安装仓库开发依赖

npm install --legacy-peer-deps

Example 已改为从 npm 公仓安装 @hxa-rn/[email protected],不再使用本地 file:../xxx.tgz,运行 Example 不必再执行 npm pack。

3. 进入 example 目录,安装依赖

cd example          # 或 example_auto
npm install --legacy-peer-deps

4. 生成 JS Bundle

npm run dev

产物:harmony/entry/src/main/resources/rawfile/bundle.harmony.js

5. 用 DevEco Studio 打开鸿蒙工程

  • 打开 DevEco Studio
  • 选择 example/harmony(或 example_auto/harmony)目录
  • 等待 Sync 完成

6. 编译并运行 HAP

在 DevEco Studio 中点击运行按钮,将 HAP 安装到设备/模拟器。

注意:Example 中已预置插件依赖和 Package 注册,无需手动配置 Link。Example 已声明 ohos.permission.PRIVACY_WINDOW。

约束与限制

兼容性

  • 鸿蒙 SDK:API 12+
  • 上游 RN 库:react-native-capture-protection 2.4.1
  • React Native / RNOH:0.72+
  • DevEco Studio:5.0+

权限

  • ohos.permission.PRIVACY_WINDOW(system_grant,声明即可,无需运行时申请)

其他

  • 隐私模式开启后,最近任务卡片显示隐私蒙层,应用内容不可见(预期行为)
