如何使用Net :: SFTP识别项目是文件还是目录？

#!/usr/bin/perl

use strict;
use warnings;
use Net::SFTP;

# 连接到远程服务器
my $sftp = Net::SFTP->new('example.com', user => 'username', password => 'password');

# 检查连接是否成功
die "Unable to connect to remote server" unless $sftp;

# 获取要检查的项目的路径
my $path = '/path/to/item';

# 获取项目的属性
my $attrs = $sftp->stat($path);

# 判断项目是文件还是目录
if ($attrs->is_file) {
    print "$path is a file\n";
} elsif ($attrs->is_dir) {
    print "$path is a directory\n";
} else {
    print "$path is neither a file nor a directory\n";
}

# 关闭连接
$sftp->disconnect;
