Downloading attachment from Exchange message with Perl - perl

Question

I am automatically downloading mails from an Exchange 2010 server via perl. So far I have managed to access the message via Exchange Web Services (EWS) and parse headers. Now I wonder how I can download the attachments of a message to a local temporary folder.
I am new to Perl language and cannot find the source code or documentation for the message data structure. Any help is appreciated.
use Email::Folder::Exchange;
use Email::Simple;
# some more code here....
my $folder = Email::Folder::Exchange->new($url, $user, $pass);
for my $message ($folder->messages) {
if ($message->header('Subject') =~ /Downloadable Message/) {
// How to access message's attachments?
}
}

Answer 1

So basically the trick is to convert the Email::Simple to Email::MIME and use Email::MIME::Attachment::Stripper to parse through each attachment. Easy ;-)
! I only copied the relevant parts... so you might need to extend it a little for reuse.
use Email::Folder::Exchange;
use Email::Simple;
use Email::MIME::Attachment::Stripper;
# some more code here....
my $folder = Email::Folder::Exchange->new($url, $user, $pass);
for my $message ($folder->messages) {
my $tmpMsg = Email::MIME->new($message->as_string);
my $stripper = Email::MIME::Attachment::Stripper->new($tmpMsg);
for my $a ($stripper->attachments()) {
next if $a->{'filename'} !~ /csv/i; #only csv attachments
my $tempdir = "C:\\temp\\";
my $tmpPath = $tmpdir . $a->{'filename'};
# Save file to temporary path
my $f = new IO::File $tmpPath, "w" or die "Cannot create file " . $tmpPath;
print $f $a->{'payload'};
}
}
