Angular HttpInterceptor Empty

lucycodes42

The @Injectable() decorator registers the YourInterceptor class as a HTTP interceptor. The intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> function takes a req object and returns an Observable that emits HttpEvent objects. The handle(req: HttpRequest<any>) function of the next object receives a req object and calls the handle() method of the HttpHandler object that was passed as an argument.
