• easy to use – implement just one interface for a standalone UI5 application
• pure ABAP – development using 100% ABAP (no JavaScript, DDL, EML or Customizing)
• low system footprint – based on a plain http handler (no BSP, OData, CDS, BOPF or RAP)
• cloud and on-premise ready – works with both language versions (ABAP for Cloud, Standard ABAP)
• high system compatibility – runs on all ABAP releases (from NW 7.02 to ABAP 2305)
• easy installation – abapGit project, no additional app deployment needed

• BTP ABAP Environment (ABAP for Cloud)
• S/4 Public Cloud ABAP Environment (ABAP for Cloud)
• S/4 Private Cloud or On-Premise (ABAP for Cloud, Standard ABAP)
• R/3 NetWeaver AS ABAP 7.50 or higher (Standard ABAP)
• R/3 NetWeaver AS ABAP 7.02 to 7.42 - use the downport repository

Install with abapGit and create a new HTTP service with the following handler:

METHOD if_http_extension~handle_request.

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

   DATA(lv_resp) = SWITCH #( server->request->get_method( )
      WHEN 'GET'  THEN z2ui5_cl_http_handler=>http_get( )
      WHEN 'POST' THEN z2ui5_cl_http_handler=>http_post(
         body      = server->request->get_cdata( ) 
         path_info = lt_header[ name = `~path_info` ]-value ) ).

   server->response->set_header_field( name = `cache-control` value = `no-cache` ).
   server->response->set_cdata( lv_resp ).
   server->response->set_status( code = 200 reason = `success` ).

ENDMETHOD.

METHOD if_http_service_extension~handle_request.
