In addition to using my blog Step by step to create QRCode in ABAP Webdynpro to generate a QR code using ABAP webdynpro, you can also generate a QR code by using the QR code to generate the service provided by the website online.
QR code online generation website:
http://www.makepic.com/qrcode.php
Enter the QR code data source, verification level and image size to be generated on the webpage, click Generate to see the generated QR code image:
The following is the code for generating a QR code using the above service using ABAP code:
DATA:ls_form type zcl_http_tool=>ty_name_pair,
lt_header type zcl_http_tool=>tt_name_pair,
lt_form type zcl_http_tool=>tt_name_pair,
lv_code type xstring.
ls_form = value #( name = 'data' value = 'testforQRCode' ).
APPEND ls_form TO lt_form.
ls_form = value #( name = 'level' value = 'M' ).
APPEND ls_form TO lt_form.
ls_form = value #( name = 'size' value = '6' ).
APPEND ls_form TO lt_form.
zcl_http_tool=>send_request( iv_url = 'http://www.makepic.com/qrcode.php'
iv_req_type = if_http_request=>co_request_method_post
it_form = lt_form ).
ls_form = value #( name = 'Referer' value = 'http://www.makepic.com/qrcode.php' ).
APPEND ls_form TO lt_header.
zcl_http_tool=>send_request( EXPORTING iv_url = 'http://www.makepic.com/mkqr.php?data=testforQRCode&level=M&size=6'
iv_req_type = if_http_request=>co_request_method_get
it_header = lt_header
IMPORTING ev_response = lv_code ).
testforQRCode corresponds to the generated QR code:
It can be successfully scanned with the QR code scanning application on the mobile phone:
The code of zcl_http_tool is on my github (because it is used for demo purposes, there is no corresponding error handling)
