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

本文介绍FA模型的三种应用组件如何绑定Stage模型的ServiceExtensionAbility组件。

PageAbility关联访问ServiceExtensionAbility

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

import featureAbility from '@ohos.ability.featureAbility';
import common from '@ohos.app.ability.common';
import Want from '@ohos.app.ability.Want';
import Logger from '../../utils/Logger';const TAG: string = 'PageInterflowFaAndStage';let serviceWant: Want = {bundleName: 'com.samples.stagemodelabilityinteraction',abilityName: 'ServiceExtAbility'
};let faConnect: common.ConnectOptions = {onConnect: (elementName, proxy) => {Logger.info(TAG, "FaConnection onConnect called.");},onDisconnect: (elementName) => {Logger.info(TAG, "FaConnection onDisconnect called.");},onFailed: (code) => {Logger.info(TAG, "FaConnection onFailed code is: " + code);}
};
let connectionId = featureAbility.connectAbility(serviceWant, faConnect);

ServiceAbility/DataAbility关联访问ServiceExtensionAbility

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

import particleAbility from '@ohos.ability.particleAbility';
import common from '@ohos.app.ability.common';
import Want from '@ohos.app.ability.Want';
import hilog from '@ohos.hilog';const TAG: string = '[Sample_FAModelAbilityDevelop]';
const domain: number = 0xFF00;let serviceWant: Want = {bundleName: 'com.samples.stagemodelabilityinteraction',abilityName: 'ServiceExtAbility'
};
let faConnect: common.ConnectOptions = {onConnect: (elementName, proxy) => {hilog.info(domain, TAG, 'FaConnection onConnect called.');},onDisconnect: (elementName) => {hilog.info(domain, TAG, 'FaConnection onDisconnect called.');},onFailed: (code) => {hilog.info(domain, TAG, 'FaConnection onFailed code is: ' + code);}
};
let connectionId = particleAbility.connectAbility(serviceWant, faConnect);
