编译报错 ArkTS:ERROR 改为 HarmonyOS 鸿蒙Next 编译报错 ArkTS:ERROR

报错信息：

 Argument of type ‘DeviceBindTask’ is not assignable to parameter of type ‘SFTask<RequestEntry, ResponseEntry>’.

  Type ‘DeviceBindTask’ is missing the following properties from type ‘SFTask<RequestEntry, ResponseEntry>’: request, response, doBeforeExecute, doAfterExecute

代码：

class SFTask<Request extends RequestEntry, Response> {
  public readonly request: Request;

  public response: Response;

  constructor(request: Request) {
    this.request = request;
  }

  // 请求前执行
  public doBeforeExecute() {

  }

  // 请求完成后执行
  public doAfterExecute() {

  }
}

export default SFTask;

继承类如下：

export class DeviceBindTask extends SFTask<DeviceBindRequestEntry, BaseModel> {
  constructor(entry: DeviceBindRequestEntry) {
    super(entry);
  }
}
