HarmonyOS 是否有退出应用的api？

import UIAbility from '@ohos.app.ability.UIAbility';  
import { BusinessError } from '@ohos.base';  
  
export default class EntryAbility extends UIAbility {  
  
  onForeground() {  
    try {  
      this.context.terminateSelf()  
        .then(() => {  
          // 执行正常业务  
          console.info('terminateSelf succeed');  
        })  
        .catch((err: BusinessError) => {  
          // 处理业务逻辑错误  
          console.error(`terminateSelf failed, code is ${err.code}, message is ${err.message}`);  
        });  
    } catch (err) {  
      // 捕获同步的参数错误  
      let code = (err as BusinessError).code;  
      let message = (err as BusinessError).message;  
      console.error(`terminateSelf failed, code is ${code}, message is ${message}`);  
    }  
  }  
}
