FH でコマンドを使用してみてください。
ファイルをアップロードする CGI フォームの開始点として使用する Perl スクリプトを次に示します (フォームを表示してアップロードを行います)。
#!/usr/bin/perl
use strict;
use warnings;
use POSIX;
use CGI::Pretty qw(:standard -any -no_xhtml -oldstyle_urls *center);
use CGI::Carp qw(fatalsToBrowser set_message);
use Upload;
# Constants
my $FILE_DIR_INTERNAL = 'Z:\webroot\tmp';
# Variables
my $ACTION = param('action') || "";
if (! $ACTION) { UploadForm() }
elsif ($ACTION eq "UploadFile") {
my $file = UploadFile($FILE_DIR_INTERNAL, 1);
print "File uploaded to $file\n<pre>";
open(F, "$file");
while(<F>) { print }
close(F);
}
そして、そのスクリプトで使用される Perl モジュールは次のとおりです。
package Upload;
use strict;
use warnings;
use POSIX;
use File::Copy;
use CGI::Pretty qw(:standard -any -no_xhtml -oldstyle_urls *center);
use CGI::Carp qw(fatalsToBrowser); # supposed to echo STDERR to browser, too
use Exporter;
our $VERSION = do{ q$Revision: 1.5 $ =~ /(\d+)\.(\d*)([^ ]*)/; sprintf "%d.%02d%s", $1, $2, $3; };
our @ISA = qw(Exporter);
our @EXPORT = qw(UploadForm UploadFile);
my $FILE_UPLOAD_PARAM = "fileUploaded";
