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));
    })
  }
}
