Previously we have discussed how to generate QRcode with SAP standard functionality:
(1) Generate QRcode with ABAP Webdynpro
(2) Generate QRcode with ABAP Code plus Adobe form template
Both solutions will generate QRCode within a PDF file.
If your requirement is to generate the QRCode in a picture file, you can use the solution described in this blog.
There are lots of websites which provide free QRCode generation service. Just google it:
DATA:ls_form type zcl_http_tool=>ty_name_pair,
lt_form type zcl_http_tool=>tt_name_pair,
lv_code type xstring.
ls_form = value #( name = 'type' value = 'TEXT' ).
APPEND ls_form TO lt_form.
ls_form = value #( name = 'foreground_color' value = '000000' ).
APPEND ls_form TO lt_form.
ls_form = value #( name = 'ecc_level' value = 'L' ).
APPEND ls_form TO lt_form.
ls_form = value #( name = 'width_pixels' value = '200' ).
APPEND ls_form TO lt_form.
ls_form = value #( name = 'dpi' value = '72' ).
APPEND ls_form TO lt_form.
ls_form = value #( name = 'file_type' value = 'png' ).
APPEND ls_form TO lt_form.
ls_form = value #( name = 'text' value = 'testforQRCode' ).
APPEND ls_form TO lt_form.
zcl_http_tool=>send_request( EXPORTING iv_url = 'http://www.qrstuff.com/generate.generate'
iv_req_type = if_http_request=>co_request_method_get
it_form = lt_form
IMPORTING ev_response = lv_code ).
