# 事件通知子系统

## 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。

## 使用说明

### 概述

CommonEvent提供发布公共事件、创建订阅者、订阅、取消订阅等的接口。

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
