Using vv_out to download IFS stream file in ASCII text format

[jcallahan]

Want to build a self service web app with NAB to allow users to select and download 80 column ASCII text files already created in an IFS directory /usr/local/myDownloads. Files are encoded in CCSID 1252 and I want them transferred as is (binary mode)

vvOut.download = '1';
vvOut.file = 'myFile80.txt';
vvOut_file('/usr/local/myDownloads/myFile80.txt':vvOut);

Just want to confirm that the IFS path is absolute and doesn't require an alias in the web server configuration

That is correct, the IFS path is absolute.

Almost there. Can display the list of available files in the directory, click on the grid item, text file transfers via the browser download mechanism, BUT..

getting this appended to the end of the source file:

Cache-Control: no-cache
Content-type: application/json

{"success" : true , "info" : "Download ISOLOS1221.txt" }

Running Valence Framework 6.1.20220405.1

Assuming that you are using the EXNABBTN base template, correct? If that is the case, you must have a couple of SetResponse procedure calls running after your call to vvOut_file.

[jcallahan]

Correct. Should I change the order of execution?

 path_name = getselectionCHAR(1:'PATH_NAME');
file_name = getselectionCHAR(1:'FILE_NAME');

vvOut.download = '1';
vvOut.file = %trim(file_name);
vvOut_file(%trim(path_name):vvOut);
//
SetResponse('success':'true');
SetResponse('info':'Download ' + %trim(file_name));

Since you're streaming a file, you should just remove the SetResponse lines altogether.

Issue resolved. Thank you.
