Interface HttpRequest<T>

Type Parameters:
T - the type of response body
public interface HttpRequest<T>
A client-side HTTP request.

Instances are created by an WebClient instance, via one of the methods corresponding to the specific HTTP methods such as WebClient.get(String), etc...

The request shall be configured prior sending, the request is immutable and when a mutator method is called, a new request is returned allowing to expose the request in a public API and apply further customization.

After the request has been configured, the methods

can be called. The sendXXX methods perform the actual request, they can be called multiple times to perform the same HTTP request at different points in time.

The handler is called back with

  • an HttpResponse instance when the HTTP response has been received
  • a failure when the HTTP request failed (like a connection error) or when the HTTP response could not be obtained (like connection or unmarshalling errors)

Most of the time, this client will buffer the HTTP response fully unless a specific BodyCodec is used such as

invalid reference 
BodyCodec#create(Handler)
.

    • port

      int port()
      Returns:
      the request port or 0 when none is set for absolute URI templates

      <U> HttpRequest<U> as(BodyCodec<U> responseCodec)
      Configure the request to decode the response with the responseCodec.
      Parameters:
      responseCodec - the response codec
      Returns:
      a reference to this, so the API can be used fluently

    • host

      HttpRequest<T> host(String value)
      Configure the request to use a new host value.

      HttpRequest<T> virtualHost(String value)
      Configure the request to use a virtual host value.

      Usually the header host (:authority pseudo header for HTTP/2) is set from the request host value since this host value resolves to the server IP address.

      Sometimes you need to set a host header for an address that does not resolve to the server IP address. The virtual host value overrides the value of the actual host header (:authority pseudo header for HTTP/2).

      The virtual host is also be used for SNI.
