官方给出的步骤是对的，就是一时不知道从何下手，自己整了下，按照这个来就行

1.步骤

打开 APP 通知功能

1.先按照这个页面进行配置SDK 集成指南 - 极光文档，主要就是下载极光sdk，然后在AGC里开通推送服务，配置调试证书，配置签名，配置应用 client_id

2.在极光平台配置包名和 appKey（Server Key 在AGC里可以下载JSON）一定要启用，包名需要和AGC的一样（json文件可以在这个文档按照配置厂商参数申请指南 - 极光文档）

3.创建新的一个Ability在product中，和EntryAbility.ets同级（就是在Entry模块中），Ability的代码下面会有，然后在module.json5中配置srcEntry字段 "srcEntry": "./ets/entryability/MyAbilityStage.ets", ,这样才可以启动这个Ability （点击通知消息打开应用的话，还是在module.json5配置actions为："action.system.home"）这个文件现在有两个Ability。一个在module下面，一个是默认的在abilities下面，module是自己新加的

4.在EntryAbility里也需要调用个方法，还需要写个方法，下面代码也有

5.在页面中使用eventhub来进行获取Registration ID

6.拿到Registration ID以后就说明成功了，这样就可以测试是否可以推送成功了

这个是测试地址极光推送，里面有个字段是HarmonyOS category 可以根据自己需求看文档填写文档中心这里需要注意（如果app在前台可以推送，后台不可以推送的话是因为AGC上没有开通消息权益，下面会详细写）

这里也有官方给出的demo感兴趣的可以自己看看资源下载 - 极光文档

2.代码

1. MyAbilityStage.ets 这个直接复制就能用，就是setAppKey这个key需要替换自己的

}export default class MyAbilityStage extends AbilityStage {onCreate() {// 应用的HAP在首次加载的时，为该Module初始化操作hilog.info(0x0000, TAG, '%{public}s', 'MyAbilityStage onCreate');JPushInterface.setChannel("demo")JPushInterface.setAppKey("你自己的key")JPushInterface.setDebug(true)JPushInterface.setCallBackMsg(new MyCallBackMsg(this.context.getApplicationContext()))}
}

2.EntryAbility.ets

import {abilityAccessCtrl,AbilityConstant,common,PermissionRequestResult,Permissions,UIAbility,Want
} from '@kit.AbilityKit';
import { hilog } from '@kit.PerformanceAnalysisKit';
import { window } from '@kit.ArkUI';
import { PreferencesUtils } from 'common';
import { notificationManager } from '@kit.NotificationKit';
import { JMessage, JPushInterface } from '@jg/push';
import { BusinessError } from '@kit.BasicServicesKit';
import { pushCommon, pushService } from '@kit.PushKit';const TAG: string = 'JPUSH-JLog-PushMessageAbility'export default class EntryAbility extends UIAbility {onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void {this.setClickWant(want)JPushInterface.init(this.context)hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onCreate');}onNewWant(want: Want, launchParam: AbilityConstant.LaunchParam): void {hilog.info(0x0000, TAG, '%{public}s', 'Ability onNewWant');super.onNewWant(want, launchParam)this.setClickWant(want);}private async setClickWant(want: Want) {let j: JMessage | undefined = await JPushInterface.setClickWant(want);hilog.info(0x0000, TAG, '%{public}s', 'setClickWant: ' + JSON.stringify(j));}onDestroy(): void {hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onDestroy');}onWindowStageCreate(windowStage: window.WindowStage) {// Main window is created, set main page for this abilityhilog.info(0x0000, 'testTag', '%{public}s', 'Ability onWindowStageCreate');// 读取本地token（异步）windowStage.loadContent('pages/Index', (err) => {if (err.code) {hilog.error(0x0000, 'testTag', 'Failed to load the content. Cause: %{public}s', JSON.stringify(err) ?? '');return;}hilog.info(0x0000, 'testTag', 'Succeeded in loading the content.');});}onWindowStageDestroy(): void {// Main window is destroyed, release UI related resourceshilog.info(0x0000, 'testTag', '%{public}s', 'Ability onWindowStageDestroy');}onForeground(): void {// Ability has brought to foregroundhilog.info(0x0000, 'testTag', '%{public}s', 'Ability onForeground');}onBackground(): void {// Ability has back to backgroundhilog.info(0x0000, 'testTag', '%{public}s', 'Ability onBackground');}
}

3.页面调用

onEventhub() {// 获取eventHublet eventhub = this.context.getApplicationContext().eventHub;hilog.info(0x0000, TAG, '%{public}s', 'jPush_event on');// 执行订阅操作eventhub.on('jPush_event_rid', (data: string) => {// 触发事件，完成相应的业务操作hilog.info(0x0000, TAG, 'jPush_event_rid:' + JSON.stringify(data));Logger.log(data)this.rid = "rid: " + data;}); // 执行订阅操作eventhub.on('jPush_event_isConnected', (data: boolean) => {// 触发事件，完成相应的业务操作hilog.info(0x0000, TAG, 'jPush_event_isConnected:' + JSON.stringify(data));this.rid = "rid: " + JPushInterface.getRegistrationId();Logger.log(JPushInterface.getRegistrationId() + 'hhhhhhhhh')});// 执行订阅操作eventhub.on('jPush_event', (data: string) => {// 触发事件，完成相应的业务操作hilog.info(0x0000, TAG, '%{public}s', 'jPush_event:' + data);this.message = this.message + "\n" + JSON.stringify(data)this.message = this.message + "\n" + "============================"});}aboutToAppear(): void {this.onEventhub()}

4.前台推送，后台不推送Bug

是因为AGC消息权益没有开通激活，根据自己的业务需求开通，激活以后需要根据业务类型取值

自分类权益生效后，应用的推送消息将根据category字段进行归类。

官方文档：文档中心

5.常用的几个接受消息的Emit

1.这个是Ability里的监听收到消息的函数

 onArrivedMessage(jMessage: JMessage) {hilog.info(0x0000, TAG, '%{public}s', 'onArrivedMessage jMessage:' + JSON.stringify(jMessage));this.context.eventHub.emit('jPush_event', "onArrivedMessage:" + JSON.stringify(jMessage));}

2.这个是页面调用收到消息的消息体

   eventhub.on('jPush_event', (data: string) => {// 设置到 JPushLogger.log('1231132123121' + data)});

3.这个是点击通知栏跳转进app以后的函数（我这边自己更换了emite的title）不和接受消息的emit同一个

  onClickMessage(jMessage: JMessage) {Logger.log(jMessage)hilog.info(0x0000, TAG, '%{public}s', 'onClickMessage jMessage:' + JSON.stringify(jMessage));this.context.eventHub.emit('jPush_event_delete', JSON.stringify(jMessage));}
