如何将这两个服务调用与一个单独的输出结果作为其他输入相结合? [英] How to combine this two sevice call with in the single effect one out put result as input of other?

问题描述

这是我的原始效果.它从服务调用中加载数据.

  getReviewEffect $ = createEffect(()=> this.actions $ .pipe(ofType(INIT)，mergeMap(({{Id})=> this.ReviewService.findByP(Id，new Date(new Date().setDate(new Date().getDate()-30))，new Date(new Date().setDate(new Date().getDate()+ 30))，批准").管道(mergeMap(评论=> {返回[ReviewLoadSuccess({drugReviews:getReviews(reviews)})];})，catchError(错误=> {返回(ReviewLoadFailure({error:error})));}))))); 

但是ID，我是在加载时调用此服务调用的.

  this.ocService.getActiveoc().subscribe((oc => {this.Id = oc.id;})); 

我还需要将上面的代码放入我的效果中并进行初始加载.需要一些专家的帮助.并且还需要一种更好的方式来指定未来30天的日期.

--------------更新------------------------------

我尝试执行此操作，如下所示，但它已编译错误.需要一些专家帮助来解决它，

  getReviewEffect $ = createEffect(()=> this.actions $ .pipe(ofType(INIT)，mergeMap((Id)=> this.socService.getActiveoc().toPromise().thenoc => {return oc.id}).then((((Id)=> {this.drugReviewService.findBy(Id，new Date()，new Date(new Date().setDate(new Date().getDate()+ 1))，批准").管道(mergeMap(评论=> {返回ReviewLoadSuccess({评论:getReviews(评论)})];})，catchError(错误=> {返回(ReviewLoadFailure({error:error})));}))})))) 

解决方案

您可以尝试使用 Promise()

  this.ocService.getActiveoc().toPromise().then(res => {this.Id = res ['id']}).then(()=> {getReviewEffect $ = createEffect(()=> this.actions $ .pipe(ofType(INIT)，mergeMap(({{Id})=> this.ReviewService.findByP(Id，new Date(newDate().setDate(new Date().getDate()-30))，new Date(new Date().setDate(new Date().getDate()+ 30))，批准").管道(mergeMap(评论=> {返回[ReviewLoadSuccess({drugReviews:getReviews(reviews)})];})，catchError(错误=> {返回(ReviewLoadFailure({error:error})));})))));}) 

This is my original effect. It loads data from a service call.

   getReviewEffect$ = createEffect(() => this.actions$.pipe(
    ofType(INIT),
    mergeMap(({ Id  }) => this.ReviewService.findByP(Id, new Date(new Date().setDate(new Date().getDate() -30)),
      new Date(new Date().setDate(new Date().getDate() + 30)), 'Approval')
      .pipe(
        mergeMap(reviews => {
          return [ReviewLoadSuccess({ drugReviews: getReviews(reviews) })
          ];
        }),
        catchError(error => {
          return of(ReviewLoadFailure({ error: error }));
        })
      )
    )));

But the id, I take form this service call in loading.

this.ocService.getActiveoc().subscribe((oc => {
  this.Id = oc.id;
}));

I need to put the above code also, inside my effect and initial load it.need some expert help to do that. And also need to better way to given a date in 30 in the future and past.

--------------updated ------------------------------

I try to do it, like below but it was compiled error. need some expert help to resolve it,

getReviewEffect$ = createEffect(() => this.actions$.pipe(
    ofType(INIT),
    mergeMap((Id)=> this.socService.getActiveoc().toPromise().thenoc=>{return oc.id})
    .then(((Id)=>{
      this.drugReviewService.findBy(Id, new Date(),
      new Date(new Date().setDate(new Date().getDate() + 1)), 'Approval')
      .pipe(
        mergeMap(reviews => {
          return ReviewLoadSuccess({ Reviews: getReviews(reviews) })
          ];
        }),
        catchError(error => {
          return of(ReviewLoadFailure({ error: error }));
        })
      )
    })
    )))

解决方案

You could try to use a Promise()

this.ocService.getActiveoc().toPromise()
   .then(res => {this.Id = res['id']})
   .then(() => { 
      getReviewEffect$ = createEffect(() => this.actions$.pipe(
      ofType(INIT),
      mergeMap(({ Id  }) => this.ReviewService.findByP(Id, new Date(new                       
      Date().setDate(new Date().getDate() -30)),
      new Date(new Date().setDate(new Date().getDate() + 30)), 'Approval')
      .pipe(
        mergeMap(reviews => {
          return [ReviewLoadSuccess({ drugReviews: getReviews(reviews) })
          ];
        }),
        catchError(error => {
          return of(ReviewLoadFailure({ error: error }));
        })
      )
    )));
 })
