Thanks for the update! Sometimes calling the native tools turns out to be the "easiest" way to go, in cases like that I usually make sure the interface is as clean as possible.

I've not actually integrated into my scripts, but as a proof of concept, it works.

A quick test shows me that something like this seems to work:

use IPC::Run3 'run3'; run3 ['powershell', '-Command', 'Invoke-WebRequest', '-Uri', $uri, '-OutFile', $filename, '-UseDefaultCredentials']; $? and die "run3 failed with \$?=$?";

(I'm using IPC::Run3 because newer versions use Win32::ShellQuote under the hood, and it allows redirection of STDIN/OUT/ERR if desired. For really complicated cases, I guess PowerShell's -EncodedCommand is probably the way to go.)

Update: Wrapped up in a function:

use File::Temp qw/tempfile/; use IPC::Run3 'run3'; sub invoke_webrequest { my $uri = shift; my ($tfh,$tfn) = tempfile(UNLINK=>1); close $tfh; run3 ['powershell', '-Command', 'Invoke-WebRequest', '-Uri', $uri, '-OutFile', $tfn, '-UseDefaultCredentials']; $? and die "run3 failed with \$?=$?"; open my $fh, '<', $tfn or die "$tfn: $!"; my $data = do { local $/; <$fh> }; close $fh; unlink $tfn; return $data; }
