Question

请参阅下面的上传脚本。它的工作原理，但我想要做的是使用我的FTP站点用于 Upload_dir ，而不是我的网站的本地目录，该目录由我的服务提供商托管。

请建议我应该做些什么来使这项工作！提前谢谢

#!/usr/bin/perl
use CGI::Carp qw(fatalsToBrowser);
use CGI;
use File::Basename;
$CGI::POST_MAX = 1024 * 5000;
my $safe_filename_characters = "a-zA-Z0-9_.-";
my $upload_dir = "MyWebsite/upload";
my $query = new CGI;
my $filename = $query->param("photo");
my $email_address = $query->param("email_address");
if ( !$filename ) { print $query->header ( );
print "There was a problem uploading your photo (try a smaller file).";
exit; } my ( $name, $path, $extension ) = fileparse ( $filename, '\..*' );
$filename = $name . $extension;
$filename =~ tr/ /_/;
$filename =~ s/[^$safe_filename_characters]//g;
if ( $filename =~ /^([$safe_filename_characters]+)$/ ) { $filename = $1;
} else { die "Filename contains invalid characters";
} my $upload_filehandle = $query->upload("photo");
open ( UPLOADFILE, ">$upload_dir/$filename" ) or die "$!";
binmode UPLOADFILE;
print $query->header();
while ( <$upload_filehandle> )
{
  print UPLOADFILE;
}
close UPLOADFILE;
print $query->header ( ); print qq~

我想最简单的方法是像你一样上传到本地文件。上传文件后，您应该添加sime Net :: FTP代码，将文件从Web服务器发送到您的FTP服务器。您的服务提供商需要允许传出FTP才能正常工作。

use Net::FTP;
...
close UPLOADFILE;
my $ftp = Net::FTP->new( $your_ftp )         || die "$@";
$ftp->login($ftp_user,$ftp_pswd)             || die $ftp->message;
$ftp->cwd($ftp_dir)                          || die $ftp->message;
$ftp->binary();
$ftp->pasv();   # optional. May be required
$ftp->put("$upload_dir/$filename",$filename) || die $ftp->message;
undef $ftp;
...

顺便说一下，我通常使用自动生成的本地文件名来确保两个用户同时使用相同的名称上传不会导致问题。我通常使用像time().'-'.$$

这样的东西
