Question

我是angular和rxjs的新手，我需要知道如何读取地图上来自forkJoin的数据。

ngOnInit(): void {
    this.serviceData.currentService.subscribe(service =>
        this.serviceFam.getAllFamilles().pipe(
          switchMap(familles =>
            forkJoin(
              familles.map(f => forkJoin(
                this.serviceAffecter.getAffecterServiceFamille(service, f.nom),
                this.serviceOpe.getOperationsServiceFamille(service, f.nom)
                ).pipe(
                map(([listAffecter, listeOperations]) => [f, listAffecter, listeOperations])
                )
              )
            )
          )
        ).pipe(switchMap((data: [Famille, Affecter, Operation][]) => {
          return forkJoin(data.map((f, a, o) => {

            //Here I want to read my data

          }));
        }))
    );

    this.serviceData.changeAffaire(4);
  }

阅读起来很混乱，但是在switchMap的代码内，但是您可以使用https://github.com/Faltenreich/SkeletonLayout运算符记录响应。

forkJoin(
  familles.map(f => forkJoin(
    this.serviceAffecter.getAffecterServiceFamille(service, f.nom),
    this.serviceOpe.getOperationsServiceFamille(service, f.nom)
  ).pipe(
    tap(res => {
      console.log(res);
    }),
    map(([listAffecter, listeOperations]) => [f, listAffecter, listeOperations])
  ))
)

如何读取来自forkjoin映射的数据？
