ABAP for Cloud:

METHOD if_http_service_extension~handle_request.

   z2ui5_cl_http_handler=>client = VALUE #(
      t_header = request->get_header_fields( )
      t_param  = request->get_form_fields( )
      body     = request->get_text( ) ).

   DATA(lv_resp) = SWITCH #( request->get_method( )
      WHEN 'GET'  THEN z2ui5_cl_http_handler=>http_get( )
      WHEN 'POST' THEN z2ui5_cl_http_handler=>http_post( ) ).

   response->set_status( 200 )->set_text( lv_resp ).

ENDMETHOD.

Standard ABAP:

METHOD if_http_extension~handle_request.

   DATA lt_header TYPE tihttpnvp.
   server->request->get_header_fields( CHANGING fields = lt_header ).

   DATA lt_param TYPE tihttpnvp.
   server->request->get_form_fields( CHANGING fields = lt_param ).

   z2ui5_cl_http_handler=>client = VALUE #(
      t_header = lt_header
      t_param  = lt_param
      body     = server->request->get_cdata( ) ).

   DATA(lv_resp) = SWITCH #( server->request->get_method( )
