observable

问题 Suppose I have this : public class UploadDicomSet { public UploadDicomSet() { var cachCleanTimer = Observable.Interval(TimeSpan.FromMinutes(2)); cachCleanTimer.Subscribe(CheckUploadSetList); //Start subscriber } void CheckUploadSetList(long interval) { //Stop and dispose subscriber } public void AddDicomFile(SharedLib.DicomFile dicomFile) { //Renew subscriber, call CheckUploadSetList 2 minutes later } } 1- in CheckUploadSetList I want to dispose or finish observable 2- in AddDicomFile I want

问题 I have the following observables: public ngAfterViewInit(): void { fromEvent(this.showFeaturesButton.nativeElement, 'click').pipe( takeUntil(this.ngUnsubscribe), withLatestFrom(this.store.pipe(select(fromClientStorage.getSubscription))) ).subscribe(([_event, subscription]) => { this.featureModal.open(FeatureListComponent, { data: { features: subscription.features }, }); }); } I am trying to test using: it('should call modal when feature button is clicked', () => { const subscription:

问题 I'm using JWT with refresh token strategy as authentication and I have an interceptor in my Angular client that sends the token as a header. I check for expiration before sending, and refresh the token with my refreshToken if needed. The problem is when sending 2 (or more) requests, both trying to refresh the token. I need a function that sends req for refresh token and when called multiple times at once, makes only 1 http req to the server for refresh and returns the new updated token to all

问题 As definied combineLatest in rx emites only if all values have changed at least once. (so long as each of the source Observables has emitted at least one item) I use it to manipulate views within my android views. For example, I enable a call to action button as soon as all observables emitted a valid value. Otherwise I disable it. Observable.combineLatest( toObservable(email), toObservable(username), toObservable(status), toObservable(phonenumber), toObservable(birthdate), Function5<String,

问题 I'm trying to add a boolean value to a BehaviorSubject. However, when I try to console log it says that it is undefined. What I'm doing wrong? This is how I declare it. isDesktopWidth: BehaviorSubject<boolean>; And this is how I use it changeSideBarWidth() { if (this.innerWidth > 767) { this.isDesktopWidth.next(true); } else { this.isDesktopWidth.next(false); } } And then in the ngOnInit this.changeSideBarWidth(); console.log(this.isDesktopWidth.value); But it doesn't display anything in the

问题 In service I have this defined: getAllHTTP(): Observable<IUser[]> { return this.http.get(`${this.url}/users`) .map(res => res.json()) .catch(err => Observable.throw(err)); } and in the component: ngOnInit() { const self = this; this._uService.getAllHTTP().subscribe( function (data) { console.log(data); self.listOfUsers = data }, (error) => console.error(error) ); } So now I wanted to filter the data before passing the observable to component and I did this: getAllHTTP(): Observable<IUser[]> {

问题 I have been trying to create a function that is similar to http.get(...) but not doing any http. Basically what I have done is that I defined a function async myFunc(): Observable<string> { var myObservable: Observable<string>; //..... // the rest of the function's code comes here // ... return myObservable; } But I always get an error that it is not compatible with ES5/ES3 and should return a Promise object? But I am wondering how it became possible with Angular 5's http.get function? Where
