Angular 最迟不回来

我有以下效果

  @Effect()
  createMission$ = this.actions$.pipe(
    ofType<featureActions.CreateMissionRequest>(featureActions.ActionTypes.CreateMissionRequest),
    withLatestFrom(this.store$),
    map(([action, state]) => {
      return this.dataService.createMission(state.missions.entities[action.payload.routeId])).pipe(
        map(response => new featureActions.CreateMissionSuccess({response, mission: state.missions.entities[action.payload.routeId]})),
        catchError((error: HttpErrorResponse) => {
          return of(new featureActions.CreateMissionFailed({error}));
        }),
      );
    }),
  );

我面临的问题是，如果我执行后面的实现，我将不会有两个可观察的一个用于行动，一个用于任务，而只有一个

我不知道如何更改才能使其工作

现在您已将任务选择逻辑移动到选择器，您似乎不需要@Effect中的操作

类似的东西应该/可能在下面未经测试的代码中工作

你有一个可以分享的最简单的例子吗？另外，您为什么需要为后一种实现采取行动。你能用任务对象来调用你的数据服务吗？但是_任务在地图上是可见的。你试过了吗？我没有更改您的代码流，因为您只是询问在map函数中没有actioninput。我只是告诉你如何删除。是的，我尝试过，但我以类似的方式修复了它。你展示的方法返回一个来自withlatest的可观测值，并且不是我想要的类型，也许如果你能提供一个工作小提琴或stackblitz，我可以更有效地帮助你。你可能会，但没关系，不用担心，谢谢^^

export const featureAdapter: EntityAdapter<IMissionRoute> = createEntityAdapter<IMissionRoute>({
  selectId: model => model.routeId,
});
export const selectAllEntities: (state: object) => Dictionary<IMissionRoute> = featureAdapter.getSelectors(selectMissionState).selectEntities;


export const getById = () => createSelector(
  selectAllEntities,
  (entities, props) => entities[props.id]
);

    withLatestFrom((action) => this.store$.pipe(select(MissionsStoreSelectors.getById(), {id : action.payload.routeId}))),
    map(([action, mission]) => {
          /// 
     }

 @Effect()
  createMission$ = this.actions$.pipe(
    ofType<featureActions.CreateMissionRequest>(featureActions.ActionTypes.CreateMissionRequest),
    withLatestFrom((action) => this.store$.pipe(select(MissionsStoreSelectors.getById(), {id : action.payload.routeId}))),
    map(_mission => {
      return this.dataService.createMission(_mission).pipe(
        map(response => new featureActions.CreateMissionSuccess({response, mission: _mission})),
