Overview

class HttpHandler {
  handle(req: HttpRequest<any>): Observable<HttpEvent<any>>
}

Description

Transforms an HttpRequest into a stream of HttpEvents, one of which will likely be a HttpResponse.

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.
