How to show file name when calling GET_STREAM

This document is about how to enhancement our OData service  – Download File.


Currently base on training material, we usually redefine GET_STREAM method and pass mime type and stream value to the result.

ls_streammime_type = outputreturnMIME_TYPE .
ls_stream
-value = outputreturnDOCUMENT_STREAM .
copy_data_to_ref
( EXPORTING is_data = ls_stream
CHANGING  cr_data = er_stream ).

This works, however the problem is if you trigger the service in Chrome. You can only get a document with named ‘entity’.

Problem

  • What if customer has already stored file name in ECM or in Database? They want to see the real name.
  • What if customer don’t want to direct download, they may want to review the file before download.

Solution

Solution to this is to set a header to http framework. I attached code below.

DATA ls_lheader TYPE ihttpnvp.
“DATA lv_filename TYPE string.
“lv_filename = escape( val = lv_filename format = cl_abap_format=>e_url ).
ls_lheader
name = ‘Content-Disposition’.
ls_lheader
value = ‘outline; filename=”Mobile.pdf”;’.
set_header
( is_header = ls_lheader ).

ls_streammime_type = outputreturnMIME_TYPE .
ls_stream
value = outputreturnDOCUMENT_STREAM .
copy_data_to_ref
( EXPORTING is_data = ls_stream
CHANGING  cr_data = er_stream ).

Let’s test the result now:

If customer want to preview the document instead of directly download, please change code as below.

ls_lheadervalue = ‘inline; filename=”Mobile.pdf”;’.

Let’s test the result:

A new page was opened for preview, you can right click and choose to save. File name ‘Mobile.pdf’ comes up.

      Hi,

      I have a Master-Detail app. The pdf file opens successfully in the browser as planned.

      But the file is still titled $value.pdf, and switching outline/inline has no effect.

      ls_stream-value = pdf_stream.
      ls_stream-mime_type = 'application/pdf'.
      ls_header-name = 'Content-Disposition'.
      ls_header-value = 'inline; filename="Report.pdf";'.
      
      set_header( is_header = ls_header ).
      copy_data_to_ref( EXPORTING is_data = ls_stream
                        CHANGING  cr_data = er_stream ).

      Best Regards.

      ls_header-value = |attachment; filename="test.pdf"|.

      You have to change inline to attachment to enable direct download request from your browser.

      Just noticed that if you want to download the file, you should choose "attachment" instead of "outline", more information here: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Disposition
