解决方法
只需注意：但是您将编写它,不要将其保存在可从Web服务器访问的位置.
现在到了这一点：下面是我用了一段时间进行照片上传的脚本.它可能需要一些调整,但应该告诉你的方式.
由于图像没有上传到网络可访问的目录,我们有单独的过程检查它,调整大小,放置水印并将其放置在可以访问的位置.
#!/usr/bin/perl -wT
use strict;
use CGI;
use CGI::Carp qw ( fatalsToBrowser );
use File::Basename;
$CGI::POST_MAX = 1024 * 5000;
my $safe_filename_characters = "a-zA-Z0-9_.-";
my $upload_dir = "/home/www/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;

my $upload_filehandle = $query->upload("photo");

close UPLOADFILE;
