# 公共事件子系统 ## 简介 OpenHarmony通过CES（Common Event Service，公共事件服务）为应用程序提供订阅、发布、退订公共事件的能力。 公共事件可分为系统公共事件和自定义公共事件。 - 系统公共事件：系统将收集到的事件信息，根据系统策略发送给订阅该事件的用户程序。 例如：系统关键服务发布的系统事件（例如：hap安装，更新，卸载等）。 - 自定义公共事件：应用自定义一些公共事件用来实现跨应用的事件通信能力。 每个应用都可以按需订阅公共事件，订阅成功且公共事件发布，系统会把其发送给应用。这些公共事件可能来自系统、其他应用和应用自身。 ### 架构图 **图1** 子系统架构图 ![子系统架构图](figures/cesfwk_architecture_diagram.png "公共事件服务架构图") ## 目录 ```

公共事件的由string类型的event和CommonEventPublishData类型的options两部分组成，event表示公共事件的名称，options表示公共事件的属性信息。 CommonEventSubscribeInfo类型为订阅信息，用于创建公共事件订阅者，可以指定订阅者要订阅的公共事件，要求发布者需要具备的权限，订阅者的优先级等等。 CommonEventSubscriber类型为公共事件订阅者，用于获取所接受公共事件的相关信息，及设定公共事件的处理信息。 使用功能接口前，需要导入相关模块。 ```js import CommonEvent from '@ohos.commonevent'; ``` ### 发布公共事件 #### CommonEvent.publish(event: string, callback:
