Problems Downloading binary file with HTTP_GET

Hi Gurus!

I need to download a .ZIP file from internet, and write it in a specified path. After writing the file, I try to execute it, and I get a message that the file is corrupt. If I want to download a .TXT file, the operation works well.

Here is my code:


REPORT  z_http_test.


PARAMETERS : uri(100) LOWER CASE
DEFAULT 'http://www.sdn.sap.com/irj/boc/index?rid=/library/uuid/a0a1c942-2d81-2b10-48b5-a5ab5f35a5cb&overridelayout=true' .

PARAMETERS:  p_file_i    TYPE rlgrap-filename MEMORY ID filei OBLIGATORY default 'D:usrsapInterfacesdk.zip'.


AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_file_i.

  DATA: vl_path LIKE  dxfields-longpath.

  CALL FUNCTION 'F4_DXFILENAME_TOPRECURSION'
    EXPORTING
      i_location_flag = 'A'
      i_server        = ' '
      i_path          = 'D:usrsapInterfacesdk.zip'
      filemask        = '*.*'
      fileoperation   = 'R'
    IMPORTING
      o_path          = vl_path
    EXCEPTIONS
      rfc_error       = 1
      error_with_gui  = 2
      OTHERS          = 3.

  IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
            WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ELSE.
    p_file_i = vl_path.
  ENDIF.

  OPEN DATASET p_file_i FOR OUTPUT IN BINARY MODE.

  IF sy-subrc <> 0.
  ELSE.

    LOOP AT t_response_body INTO wa_response_body.

      TRANSFER wa_response_body TO p_file_i.

    ENDLOOP.

  ENDIF.

  CLOSE DATASET p_file_i.

Any ideas what I´m doing wrong?

Thanks in advance.

Esteban

That's because you are putting data into CHAR table, plus blankstocrlf = 'X' - corrupts lines by putting CRLF in them

Take for example


DATA:   t_response_body    TYPE truxs_xml_table.



CALL FUNCTION 'HTTP_GET'
    EXPORTING
          blankstocrlf                      = ' '
