Stage模型绑定FA模型ServiceAbility的方法

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@Componentstruct 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。
