WDA基础十三：常用模板管理

常用的模板一般是SMW0和OAOR，根据不同需求来的。

WAD有个不好的地方就是不支持GUI上的OLE和DOI，所以需要做转换，下面是常用的方式：

FUNCTION ZCRM_DOWNLOAD_TEMPLATE
*"----------------------------------------------------------------------
*"*"Local Interface:
*"  IMPORTING
*"     REFERENCE(IV_OBJID) TYPE  W3OBJID
*"----------------------------------------------------------------------
  DATA:
    LS_FILEKEY TYPE          WWWDATATAB,
    LT_MIME    TYPE TABLE OF W3MIME.

  DATA:
    LV_XSTRING          TYPE XSTRING,
    LV_FILENAME         TYPE STRING,
    LV_MIME_TYPE        TYPE STRING.

  LS_FILEKEY-RELID = 'MI'.
  LS_FILEKEY-OBJID = IV_OBJID.

  CALL FUNCTION 'WWWDATA_IMPORT'
    EXPORTING
      KEY    = LS_FILEKEY
    TABLES
      MIME   = LT_MIME
    EXCEPTIONS
      OTHERS = 1.

  IF sy-subrc <> 0.
    RETURN.
  ENDIF.

  CALL METHOD CL_BCS_CONVERT=>SOLIX_TO_XSTRING
    EXPORTING
      IT_SOLIX   = LT_MIME
*     IV_SIZE    =
    RECEIVING
      EV_XSTRING = LV_XSTRING.

  SELECT SINGLE VALUE INTO LV_MIME_TYPE
    FROM WWWPARAMS
    WHERE RELID = LS_FILEKEY-RELID
    AND OBJID = LS_FILEKEY-OBJID
    AND NAME = 'fileextension'.

  SELECT SINGLE VALUE INTO LV_FILENAME
    FROM WWWPARAMS
    WHERE RELID = LS_FILEKEY-RELID
    AND OBJID = LS_FILEKEY-OBJID
    AND NAME = 'filename'.

  CL_WD_RUNTIME_SERVICES=>ATTACH_FILE_TO_RESPONSE(
    EXPORTING
      I_FILENAME      = LV_FILENAME
      I_CONTENT       = LV_XSTRING
      I_MIME_TYPE     = LV_MIME_TYPE
      I_IN_NEW_WINDOW = ABAP_FALSE
      I_INPLACE       = ABAP_FALSE ).



ENDFUNCTION.

后来做FTP的时候就想到了另一个办法：

文件上传下载类型的模板。。。
