class
Transforms an HttpRequest
into a stream of HttpEvent
s, one of which will likely be a HttpResponse
.
abstract class HttpHandler { abstract handle(req: HttpRequest<any>): Observable<HttpEvent<any>> }
HttpHandler
is injectable. When injected, the handler instance dispatches requests to the first interceptor in the chain, which dispatches to the second, etc, eventually reaching the HttpBackend
.
In an HttpInterceptor
, the HttpHandler
parameter is the next interceptor in the chain.
