Missing filename header

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks,
I am trying to download .exe file from the server, I can fetch that file but while running the exe file, I get below error,
"Missing filename header".
below is the code:

use strict;
use LWP::Simple;


my $url = "http://server:port/ws/1/console/webstart?full=true";
 

my $file = "Console.exe";


my $code = getstore($url, "$file");

print "CODE : $code\n";
[download]

Can you please help me to get rid of this error.
Thanks & Regards.

Have you read LWP::Simple? What filename to you expect the file to be stored in? Where does that filename come from? My guess is that if no filename is given by the program, `LWP::Simple::getstore` will fall back on the `Content-Disposition` header and the filename supplied there. But the error message suggests that the page is sending no such header. My suggestion is that you inspect the headers you get back, and also look at the content that is returned by that URL. ~~If all else fails, why don't you manually supply the filename?~~ You supply the filename, so are you really, really sure that the code you are running produces the error message you are seeing?

Your access to that URL is not authorized.	[reply]

Hi Hippo, This GET request does need authentication actually, I can download from the browser and working fine when downloaded from the browser. Thanks.	[reply]

I also tried with below, but it doesn't seem to be working. `print "Content-Type:application/vnd.microsoft.portable-executable\n"; print "Content-Disposition:attachment;filename='BCM_console.exe'\n\n";` [download]	[reply] [d/l]

HI Corion, I have given that filename as I wanted to store it by that name. I checked with the head($url) method of LWP::useragent, which returns nothing. why don't you manually supply the filename? Can you tell me, how do we do that. Thanks.	[reply]
