OpenHarmon3.2 一键安装系统应用

在上一篇OpenHarmony3.2 安装系统应用 中介绍了如何手动安装系统应用, 过程中读取签名指纹和安装, 权限配置文件的读写比较麻烦, 所以想到使用python脚本来实现.
但涉及到签名的部分还需手动配置, 详情请参考3.2安装系统应用第一章节

1. 使用示例

打开终端, 键入

# python install_sys_hap.py {hap_path}
python install_sys_hap.py C:\target.hap

在这里插入图片描述

2. 下载, 配置

脚本使用python实现, 主要功能点为: 解析hap包获取包名和权限列表; hap签名指纹的获取; 更新预原装配置文件, 除了第二点获取签名指纹, 其他两个功能都是简单的io流, 主要难点在hap签名指纹的获取, 看了下系统源码, 发现安全子系统有暴露相关能力, 所以采用编写二进制程序依赖该部件实现签名指纹获取. 目前提供OpenHarmony 3.2版本 arm32和arm64位, 如其他版本可能需要自己编译, 关键代码可参考第四节编译dev_kits

(20231018更新)脚本及依赖整合, 下载即可, 章节3章节4为源码实现, 可参考

4. 手动编译dev_kits

dev_kits是个人为OH的开发工具, 此处只介绍hap指纹获取的关键部分, hap指纹功能依赖安全子系统appverify组件提供app验证暴露能力实现

  1. 链接security/appverify, 引入头文件
ohos_executable("dev_kits") {
    sources = ["dev_kits.cpp" ]
    include_dirs = [ "//base/security/appverify/interfaces/innerkits/appverify/include" ]
    deps = [ "//base/security/appverify/interfaces/innerkits/appverify:libhapverify" ]
    subsystem_name = "{subsystem_name}"
    part_name = "{part_name}"
}
