包管理组件

简介

包管理组件,是OpenHarmony为开发者提供的安装包管理框架。包管理组件的由如下模块组成:

图 1 包管理组件框架图

  • BundleKit:是包管理服务对外提供的接口,有安装/卸载接口、包信息查询接口、包状态变化监听接口。

  • 包扫描子模块:用来解析本地预制或者安装的安装包,提取里面的各种信息,供管理子模块进行管理,持久化。

  • 包安装子模块:负责安装,卸载,升级一个包。

  • 包安装服务:一个单独进程的用于创建删除安装目录,具有较高的权限。

  • 包管理子模块:管理安装包相关的信息,存储持久化包信息。

  • 包安全管理子模块:签名检查、权限授予、权限管理。

  • 包管理服务为BundleMs,服务运行于foudation进程中;
  • BundleMs注册到sa_manager中,sa_manager运行于foundation进程中,sa_manager为BundleMs创建线程运行环境。具体创建BundleMs服务的方式以及使用该服务的方式,可参考系统服务框架子系统;
  • 系统启动后,BundleMs会随系统启动而启动;
  • 使用bm工具可以安装指定的hap包(以hispark_taurus为例,bm工具在系统构建后放置在out/hispark_taurus/ipcamera_hispark_taurus/dev_tools/bin下):
./bin/bm install -p /nfs/xxxx.hap
