 2. 开发者在定义Service的目录下创建TS文件，自定义类继承ServiceExtensionAbility，重写基类回调函数，示例如下：
 
     ```js
+    import ServiceExtensionAbility from '@ohos.application.ServiceExtensionAbility'
     import rpc from '@ohos.rpc'
+
     class StubTest extends rpc.RemoteObject {
-      constructor(des) {
+        constructor(des) {
             super(des);
-      }
-      onRemoteRequest(code, data, reply, option) {
-      }
+        }
+        onRemoteRequest(code, data, reply, option) {
+        }
     }
