#### Installation
Install with [abapGit](https://abapgit.org)  and create a new HTTP service with the following handler:
##### Standard ABAP 🏠
```abap
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.
```
##### ABAP for Cloud :cloud:
```abap
METHOD if_http_service_extension~handle_request.
DATA(lt_header) = request->get_header_fields( ).
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(
body = request->get_text( )
path_info = lt_header[ name = `~path_info` ]-value ) ).
response->set_header_field( i_name = `cache-control` i_value = `no-cache` ).
response->set_status( 200 )->set_text( lv_resp ).
ENDMETHOD.
