Parsing the JSON to ABAP
SAP provides two classes /ui2/cl_json and /ui2/cl_data_access to work with JSONs and there are also many cool tools on https://dotabap.org/ for that.
Because it’s just a simple JSON I tried to avoid importing another class to the system. So I stayed with SAPs classes.
First deserialize the JSON with /ui2/cl_json.
" Constants for properties
CONSTANTS gc_filecontent TYPE string VALUE 'FILECONTENT' ##NO_TEXT.
CONSTANTS gc_filename TYPE string VALUE 'FILENAME' ##NO_TEXT.
CONSTANTS gc_doc_cat TYPE string VALUE 'DOCUMENTCATEGORY' ##NO_TEXT.
DATA: lr_data TYPE REF TO data.
/ui2/cl_json=>deserialize( EXPORTING json = lv_responce "the repsonse contains the json string
CHANGING data = lr_data ).
I found three similiar ways to use the class /ui2/cl_data_access to get the relevant data out of the JSON.
1. Using the class construktor and the value( ) method for earch property.
DATA: lv_filecontent_base64 TYPE string,
lv_filename TYPE string,
lv_documentcategory TYPE string.
/ui2/cl_data_access=>create( ir_data = lr_data iv_component = |D-{ gc_filecontent }| )->value( IMPORTING ev_data = lv_filecontent_base64 ).
/ui2/cl_data_access=>create( ir_data = lr_data iv_component = |D-{ gc_filename }| )->value( IMPORTING ev_data = lv_filename).
/ui2/cl_data_access=>create( ir_data = lr_data iv_component = |D-{ gc_doc_cat }| )->value( IMPORTING ev_data = lv_documentcategory ).
2. Create an instance as first step and pass the component. Reuse the instance with the value( ) method.
DATA: lv_filecontent_base64 TYPE string,
lv_filename TYPE string,
lv_documentcategory TYPE string.
DATA(lo_data_access) = /ui2/cl_data_access=>create( ir_data = lr_data
iv_component = |D-| ).
lo_data_access->at( |{ gc_filecontent }| )->value( IMPORTING ev_data = lv_filecontent_base64 ).
lo_data_access->at( |{ gc_filename }| )->value( IMPORTING ev_data = lv_filename ).
lo_data_access->at( |{ gc_doc_cat }| )->value( IMPORTING ev_data = lv_documentcategory ).
3. Use the ref( ) method to get a reference of a property value. Because it returns a generic data type (and you cannot dereference generic references) you have to use CAST combined with dereferencing (->*) to get the concret value.
DATA(lo_data_access) = /ui2/cl_data_access=>create( ir_data = lr_data
iv_component = |D-| ).
DATA(lv_filecontent_base64) = CAST string( lo_data_access->at( gc_filecontent )->ref( ) )->*.
DATA(lv_filename) = CAST string( lo_data_access->at( gc_filename )->ref( ) )->*.
DATA(lv_documentcategory) = CAST string( lo_data_access->at( gc_doc_cat )->ref( ) )->*.
In the end I stayed with version 3 because I prefere using inline declarations. The complete result looked like this:
" Constants for properties
CONSTANTS gc_filecontent TYPE string VALUE 'FILECONTENT' ##NO_TEXT.
CONSTANTS gc_filename TYPE string VALUE 'FILENAME' ##NO_TEXT.
CONSTANTS gc_doc_cat TYPE string VALUE 'DOCUMENTCATEGORY' ##NO_TEXT.
DATA: lr_data TYPE REF TO data.
/ui2/cl_json=>deserialize( EXPORTING json = lv_response "the repsonse contains the json string
CHANGING data = lr_data ).
DATA(lo_data_access) = /ui2/cl_data_access=>create( ir_data = lr_data
iv_component = |D-| ).
DATA(lv_filecontent_base64) = CAST string( lo_data_access->at( gc_filecontent )->ref( ) )->*.
DATA(lv_filename) = CAST string( lo_data_access->at( gc_filename )->ref( ) )->*.
DATA(lv_documentcategory) = CAST string( lo_data_access->at( gc_doc_cat )->ref( ) )->*.
" Decode BASE64 PDF to XString
DATA(lv_decodedx) = cl_http_utility=>if_http_utility~decode_x_base64( lv_filecontent_base64 ).
" XString to binary
DATA(lt_data) = cl_bcs_convert=>xstring_to_solix( lv_decodedx ).
" Download file
cl_gui_frontend_services=>gui_download( EXPORTING bin_filesize = xstrlen( lv_decodedx )
filename = lv_filename
filetype = 'BIN'
show_transfer_status = ' '
CHANGING data_tab = lt_data ).
When /ui2/cl_data_access is not available (SAP_UI has to be at least 7.51, see note 2526405), you can do it the oldschool way.
" Constants for properties
CONSTANTS gc_filecontent TYPE string VALUE 'FILECONTENT' ##NO_TEXT.
CONSTANTS gc_filename TYPE string VALUE 'FILENAME' ##NO_TEXT.
CONSTANTS gc_doc_cat TYPE string VALUE 'DOCUMENTCATEGORY' ##NO_TEXT.
