HarmonyOS 应用开发之Stage模型绑定FA模型ServiceAbility

本小节介绍Stage模型的两种应用组件如何绑定FA模型ServiceAbility组件。

UIAbility关联访问ServiceAbility

UIAbility关联访问ServiceAbility和UIAbility关联访问ServiceExtensionAbility的方式完全相同。

import common from '@ohos.app.ability.common';
import hilog from '@ohos.hilog';
import Logger from '../utils/Logger';
import promptAction from '@ohos.promptAction'
import Want from '@ohos.app.ability.Want';const TAG: string = '[Page_StartFAModel]';
const DOMAIN_NUMBER: number = 0xFF00;@Entry
@Component
struct Page_StartFAModel {private context = getContext(this) as common.UIAbilityContext;build() {// ...Button() {// ...}.onClick(() => {let want: Want = {bundleName: 'com.samples.famodelabilitydevelop',abilityName: 'com.samples.famodelabilitydevelop.ServiceAbility',}let options: common.ConnectOptions = {onConnect: (elementName, proxy) => {Logger.info('onConnect called.');promptAction.showToast({message: $r('app.string.ConnectFAServiceAbility')});},onDisconnect: (elementName) => {Logger.info('onDisconnect called.');},onFailed: (code) => {Logger.info('onFailed code is: ' + code);}};let connectionId = this.context.connectServiceExtensionAbility(want, options);hilog.info(DOMAIN_NUMBER, TAG, 'connectionId is ' + JSON.stringify(connectionId));})}
}

ExtensionAbility关联访问ServiceAbility

下面以ServiceExtensionAbility为例来说明ExtensionAbility关联访问ServiceAbility。ServiceExtensionAbility关联访问ServiceAbility和ServiceExtensionAbility关联访问ServiceExtensionAbility的方式完全相同。

import common from '@ohos.app.ability.common';
import hilog from '@ohos.hilog';
import Logger from '../utils/Logger';
import promptAction from '@ohos.promptAction'
import Want from '@ohos.app.ability.Want';const TAG: string = '[Page_StartFAModel]';
const DOMAIN_NUMBER: number = 0xFF00;@Entry
@Component
struct Page_StartFAModel {private context = getContext(this) as common.UIAbilityContext;build() {// ...Button() {// ...}.onClick(() => {let want: Want = {bundleName: 'com.samples.famodelabilitydevelop',abilityName: 'com.samples.famodelabilitydevelop.ServiceAbility',}let options: common.ConnectOptions = {onConnect: (elementName, proxy) => {Logger.info('onConnect called.');promptAction.showToast({message: $r('app.string.ConnectFAServiceAbility')});},onDisconnect: (elementName) => {Logger.info('onDisconnect called.');},onFailed: (code) => {Logger.info('onFailed code is: ' + code);}};let connectionId = this.context.connectServiceExtensionAbility(want, options);hilog.info(DOMAIN_NUMBER, TAG, 'connectionId is ' + JSON.stringify(connectionId));})}
}
