公共事件简介
CESCommon 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。
公共事件分类
公共事件从系统角度可分为系统公共事件和自定义公共事件。
系统公共事件CES内部定义的公共事件当前仅支持系统应用和系统服务发布例如HAP安装、更新、卸载等公共事件。目前支持的系统公共事件请参见系统公共事件列表。自定义公共事件应用定义的公共事件可用于实现跨进程的事件通信能力。 公共事件按发送方式可分为无序公共事件、有序公共事件和粘性公共事件。无序公共事件CES在转发公共事件时不考虑订阅者是否接收到该事件也不保证订阅者接收到该事件的顺序与其订阅顺序一致。有序公共事件CES在转发公共事件时根据订阅者设置的优先级等级优先将公共事件发送给优先级较高的订阅者等待其成功接收该公共事件之后再将事件发送给优先级较低的订阅者。如果有多个订阅者具有相同的优先级则他们将随机接收到公共事件。粘性公共事件能够让订阅者收到在订阅前已经发送的公共事件就是粘性公共事件。普通的公共事件只能在订阅后发送才能收到而粘性公共事件的特殊性就是可以先发送后订阅同时也支持先订阅后发送。发送粘性事件必须是系统应用或系统服务粘性事件发送后会一直存在系统中且发送者需要申请ohos.permission.COMMONEVENT_STICKY权限配置方式请参见声明权限。
运作机制
每个应用都可以按需订阅公共事件订阅成功当公共事件发布时系统会将其发送给对应的应用。这些公共事件可能来自系统、其他应用和应用自身。 图1 公共事件示意图
安全注意事项
公共事件发布方如果不加限制任何应用都可以订阅公共事件并读取相关信息应避免在公共事件中携带敏感信息。采用以下方式可以限制公共事件接收方的范围。 通过CommonEventPublishData中的subscriberPermissions参数指定订阅者所需权限。通过CommonEventPublishData中的bundleName参数指定订阅者的包名。 公共事件订阅方订阅自定义公共事件后任意应用都可以向订阅者发送潜在的恶意公共事件。采用以下方式可以限制公共事件发布方的范围。 通过CommonEventSubscribeInfo中的publisherPermission参数指定发布者所需权限。通过CommonEventSubscribeInfo中的publisherBundleName参数参数指定发布者的包名。 自定义公共事件名称应确保全局唯一否则可能与其他公共事件冲突。
常用的公共事件
公共事件类型定义在ohos.commonEventManager模块的Support枚举中。
事件名称功能描述COMMON_EVENT_POWER_CONNECTED设备连接到外部电源的公共事件的动作COMMON_EVENT_POWER_DISCONNECTED设备与外部电源断开的公共事件的动作COMMON_EVENT_CHARGING表示系统开始为电池充电的公共事件的动作COMMON_EVENT_DISCHARGING表示系统停止为电池充电的公共事件的动作COMMON_EVENT_SHUTDOWN表示设备正在关闭并将继续最终关闭的公共事件的操作COMMON_EVENT_SCREEN_ON表示由电源服务发起的设备亮屏完成的普通事件的动作COMMON_EVENT_SCREEN_OFF表示由电源服务发起的设备灭屏完成的普通事件的动作COMMON_EVENT_WIFI_POWER_STATEWi-Fi开关状态变化COMMON_EVENT_SCREEN_LOCKED表示屏幕锁定的公共事件COMMON_EVENT_SCREEN_UNLOCKED表示屏幕解锁的公共事件COMMON_EVENT_BATTERY_CHANGED表示电池充电状态、电平和其他信息发生变化的公共事件的动作COMMON_EVENT_USB_DEVICE_ATTACHED当用户设备作为USB主机时提示USB设备已挂载COMMON_EVENT_USB_DEVICE_DETACHED当用户设备作为USB主机时提示USB设备被卸载其中上面的屏幕亮屏和灭屏屏幕锁屏和解锁接电源适配器和拔掉电源适配器、开启wifi和断开wifi、插入USB设备/拔掉USB设备等。其中对于手机、平板、PC来说上面的几个事件都比较常用尤其在设备后台灭屏降功耗的时候比较有用。COMMON_EVENT_POWER_CONNECTED/COMMON_EVENT_POWER_DISCONNECTED这两个事件对于手机和平板来说就是接电源和拔掉电源在PC中就是AC和DC了。
资源调度服务中的事件转换
resource_schedule_service开源仓地址https://gitee.com/openharmony/resourceschedule_resource_schedule_service 在资源调度子系统中提供系统事件的感知以及分发例如应用启动、退出、亮灭屏等。如果需要获取系统事件并且进行相关资源调度那么可以选择以插件形式加入资源调度服务中。
作为资源调度子系统的子模块智能分组模块通过系统内应用前后台切换、用户焦点输入、后台任务的执行状态决策进程的分组调度策略并支持通过配置将调度策略映射到不同的CGROUP分组为系统的性能、功耗均衡调度提供决策依据。同时该模块向资源调度框架转发应用状态、焦点状态、后台任务状态等系统事件供插件订阅。
resource_schedule_service是接收事件决策调度策略和执行调度机制的引擎其架构图示如下 其中包括以下几个重要组成部分 1、事件管理器包含了使用对外接口直接感知系统事件以及使用监听形式感知系统事件功能。 2、应用智能分组该组件接收应用生命周期变更的事件决策应用的分组优先级是全局资源调度的根本依据。 3、插件管理器负责产品对应资源调度插件的加载接收系统和应用的事件并根据插件的订阅情况将事件分发给插件。 4、SOC统一调频服务该服务主要是从SOC统一调频插件中接收调频事件进行相关的调频仲裁最终使用内核接口设置CPU频率策略。
resource_schedule_service主要通过插件的形式进行扩展和实现系统全局资源的调度功能插件以动态链接的形式运行不同产品可以选择不同的插件进行加载。目前已知的插件有智能感知调度插件、设备状态管理插件、SOC统一调频插件。其中SOC统一调频插件的服务包含在resource_schedule_service中而另外两个插件的服务包含在其它仓内最终都是根据系统事件设置调度策略到内核中进行实施。

通过查看https://gitee.com/openharmony/resourceschedule_resource_schedule_service中的源代码我们可以看到event_controller.cpp中的void EventController::SystemAbilityStatusChangeListener::OnAddSystemAbility( int32_t systemAbilityId, const std::string deviceId)接口中添加了需要监听的公共事件代码如下
void EventController::SystemAbilityStatusChangeListener::OnAddSystemAbility(int32_t systemAbilityId, const std::string deviceId)

}void EventController::SystemAbilityStatusChangeListener::SubscribeLockScreenCommonEvent()

}inline void SubscribeCommonEvent(std::shared_ptrEventController subscriber)
{if (CommonEventManager::SubscribeCommonEvent(subscriber)) {RESSCHED_LOGI(SubscribeCommonEvent ok);} else {RESSCHED_LOGW(SubscribeCommonEvent fail);HiSysEventWrite(HiviewDFX::HiSysEvent::Domain::RSS, INIT_FAULT, HiviewDFX::HiSysEvent::EventType::FAULT,COMPONENT_NAME, MAIN,ERR_TYPE, register failure,ERR_MSG, EventController subscribe common events failed!);}
}另外资源调度服务部件是通过void EventController::OnReceiveEvent(const EventFwk::CommonEventData data)这个函数接口中转换公共事件到自定义枚举事件的代码如下
void EventController::OnReceiveEvent(const EventFwk::CommonEventData data)

} // namespace ResType
} // namespace ResourceSchedule
} // namespace OHOS接着在调频插件socperf_plugin、待机插件device_standby_plugin、分组策略插件cgroup_sched_plugin中添加对资源调度内部事件的订阅和监听回调处理。 以上三个插件都分别实现了如下三个接口
接口名接口描述function OnPluginInit(std::string libName): bool;插件初始化function OnPluginDisable(): void;插件退出function OnDispatchResource(const std::shared_ptrResData data):void;获取分发的事件
插件初始化的时候指定需要注册监听的事件。在这些事件发生的时候框架会依次分发给各个插件 此时插件需要快速处理消息接收进行资源调度需要有耗时任务则需另起线程处理处理完成后返回。 插件事件处理约束
1、插件可以用C/C实现。2、插件的事件处理必须快速完成超过1ms会打印相关告警超过10ms框架认为插件异常而进行插件退出操作。
以待机插件device_standby_plugin为例其代码实现路径为device_standby_plugin.cpp
在init()函数中订阅相关事件具体代码如下
// 插件初始化
extern C bool OnPluginInit(std::string libName)
{if (libName ! LIB_NAME) {STANDBYSERVICE_LOGI(DeviceStandbyPlugin::OnPluginInit lib name is not match);return false;}DeviceStandbyPlugin::GetInstance().Init();STANDBYSERVICE_LOGI(DeviceStandbyPlugin::OnPluginInit success.);return true;
}void DeviceStandbyPlugin::Init()
{resTypes_.insert(RES_TYPE_APP_INSTALL_UNINSTALL);resTypes_.insert(RES_TYPE_SCREEN_STATUS);resTypes_.insert(RES_TYPE_TIME_CHANGED);resTypes_.insert(RES_TYPE_NITZ_TIME_CHANGED);resTypes_.insert(RES_TYPE_TIMEZONE_CHANGED);resTypes_.insert(RES_TYPE_NITZ_TIMEZONE_CHANGED);resTypes_.insert(RES_TYPE_CHARGING_DISCHARGING);resTypes_.insert(RES_TYPE_USB_DEVICE);resTypes_.insert(RES_TYPE_CALL_STATE_CHANGED);resTypes_.insert(RES_TYPE_WIFI_P2P_STATE_CHANGED);resTypes_.insert(RES_TYPE_EFFICIENCY_RESOURCES_STATE_CHANGED);resTypes_.insert(RES_TYPE_POWER_MODE_CHANGED);resTypes_.insert(RES_TYPE_CLICK_RECOGNIZE);resTypes_.insert(RES_TYPE_MMI_INPUT_POWER_KEY);for (auto resType : resTypes_) {PluginMgr::GetInstance().SubscribeResource(LIB_NAME, resType);}STANDBYSERVICE_LOGI(DevicesStandbyPlugin::Init success);
}待机插件事件分发处理相关代码如下
// 获取分发的事件
extern C void OnDispatchResource(const std::shared_ptrResData data)
{DeviceStandbyPlugin::GetInstance().DispatchResource(data);STANDBYSERVICE_LOGD(DeviceStandbyPlugin::OnDispatchResource success.);
}待机插件退出相关代码如下
// 插件退出
extern C void OnPluginDisable()
{DeviceStandbyPlugin::GetInstance().Disable();STANDBYSERVICE_LOGI(DeviceStandbyPlugin::OnPluginDisable success.);
}void DeviceStandbyPlugin::Disable()
{for (auto resType : resTypes_) {PluginMgr::GetInstance().UnSubscribeResource(LIB_NAME, resType);}resTypes_.clear();STANDBYSERVICE_LOGI(DevicesStandbyPlugin::Disable success);
}在待机部件device_standby中使用事件
待机部件device_standby仓的源代码地址为https://gitee.com/openharmony/resourceschedule_device_standby 设备待机部件为提高设备续航降低设备功耗在设备进入待机空闲状态时系统会限制后台应用使用资源。开发者可以根据自身情况为自己的应用申请纳入待机资源管控或者暂时不被待机资源管控。 图 1 设备待机部件整体架构图 那么我们以亮屏和灭屏事件为例看一下设备待机部件device_standby是如何使用资源调度部件resource_schedule_service中定义的事件的 我们使用git clone https://gitee.com/openharmony/resourceschedule_device_standby.git命令下载好设备待机部件仓的源代码后使用VScode打开源代码搜索RES_TYPE_SCREEN_STATUS这个亮屏状态关键字如下图所示 可以看到utils\common\include\res_type.h中保持了一份资源调度模块的事件枚举 的子集代码如下所示
