在網頁上輸入要生成的二維碼數據源，校驗級別和圖片大小，點生成即可看到生成的二維碼圖片：

下面是用ABAP code 利用上述service生成二維碼的代碼：

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對應生成的二維碼：

用手機上的二維碼掃描應用能夠成功掃描出來：

zcl_http_tool的代碼在我的github上（因為用於demo用途，沒有加對應的出錯處理）
