Question

有一些与此相关的问题。.但是我经历了所有，但是我的问题没有解决。基本上我是一个初学者，所以我无法跟踪问题。

这是我的特效：

readMsg$ = createEffect(() => this.actions$.pipe(
  ofType(readMsg),
  map(action => action.payload),
  switchMap((reqPayload: MsgReadRequest) => {
      return this.httpService.post('api/msgread', reqPayload)
      .pipe(
        map((resp: MsgReadResponse) => resp.message === 'ok' ?
        readMsgSucess({payload: resp}) :
        readMsgFailure({payload: resp}),
        catchError((error: HttpErrorResponse) => of(error.message))
      )
    );
    })
));

这些是我的动作：

export const readMsg  = createAction('[Read] Msg in xl', props<{payload: NewsReadRequest}>());
export const readMsgSucess  = createAction('[Read] Msg in xl', props<{payload: NewsReadResponse}>());
export const readMsgFailure  = createAction('[Read] Msg in xl', props<{payload: NewsResponse}>());
export const htttpError  = createAction('[Read] Msg in xl error', props<{payload: HttpErrorResponse}>());

Answer 1

一个简单的错误.. 在“动作”中，我不应该提及相同的语句。.我只是更改了如下所示的动作，现在一切正常。

export const readMsg  = createAction('[Read] Msg in xl', props<{payload: NewsReadRequest}>());
export const readMsgSucess  = createAction('[Read] Msg in xl success', props<{payload: NewsReadResponse}>());
export const readMsgFailure  = createAction('[Read] Msg in xl failure', props<{payload: NewsResponse}>());
export const htttpError  = createAction('[Read] Msg in xl error', props<{payload: HttpErrorResponse}>());
