Is it possible to initiate an http request before another ongoing http request finishes (For example, fetching a token/refresh token from the server before the current request completes)?
I successfully implemented this functionality using Angular 5's httpInterceptor, but I am facing challenges with Angular 7.
intercept(request: HttpRequest<any>,next: HttpHandler): Observable<HttpEvent<any>> {
return Observable.fromPromise(this.handleAccess(request, next))
.map(response => {
console.log(response);
this.globalService.showOrShowloadingModel("hide");
return response;
})
.catch(error => {
console.log("HTTP error", error);
return Observable.of(error);
});
}
private async handleAccess(request: HttpRequest<any>,next: HttpHandler): Promise<HttpEvent<any>> {
//logic to trigger token API
await this.globalService.validateAccessToken();
return next.handle(request).toPromise();
}
