创建ServiceAbility

  1. 创建ServiceAbility。

    重写ServiceAbility的生命周期方法,添加其他Ability请求与ServiceAbility交互时的处理方法。

      import rpc from "@ohos.rpc"
      
      class FirstServiceAbilityStub extends rpc.RemoteObject {
        constructor(des: any) {
          if (typeof des === 'string') {
            super(des)
          } else {
            return
          }
        }
      }
      
      export default {
        onStart() {
          console.info('ServiceAbility onStart')
        },
        onStop() {
          console.info('ServiceAbility onStop')
        },
        onCommand(want, startId) {
          console.info('ServiceAbility onCommand')
        },
        onConnect(want) {
          console.info('ServiceAbility onConnect' + want)
          return new FirstServiceAbilityStub('test')
        },
        onDisconnect(want) {
          console.info('ServiceAbility onDisconnect' + want)
        }
      }
    
  2. 注册ServiceAbility。

    ServiceAbility需要在应用配置文件config.json中进行注册,注册类型type需要设置为service。"visible"属性表示ServiceAbility是否可以被其他应用调用,true表示可以被其他应用调用,false表示不能被其他应用调用(仅应用内可以调用)。若ServiceAbility需要被其他应用调用,注册ServiceAbility时需要设置"visible"为true,同时需要设置支持关联启动。ServiceAbility的启动规则详见组件启动规则章节。

         {
           "module": {
             "abilities": [
               {
                 "name": ".ServiceAbility",
                 "srcLanguage": "ets",
                 "srcPath": "ServiceAbility",
                 "icon": "$media:icon",
                 "description": "hap sample empty service",
                 "type": "service",
                 "visible": true
               }
             ]
           }
         }
