消息：类“PublicKeyLoader”未找到（phpseclib）

发布于 2025-01-13 07:25:06 字数 564 浏览 0 评论 0原文

我正在尝试使用 php (phpseclib) 使用私钥将 SSH 连接到 EC2 服务器。我已经从 GitHub 下载了 phpseclib 并将其添加到库文件夹中。

我的代码：

/* $dir --- contains my library folder path */
include($dir.'phpseclib3/Net/SSH2.php');
include($dir.'phpseclib3/Crypt/PublicKeyLoader.php');
$key = new PublicKeyLoader();
$key->loadPrivateKey(file_get_contents($ppkpath));

$ssh = new SSH2('ec2-xx-xxx-xxx-xxx.compute-1.amazonaws.com');
if (!$ssh->login('ec2-user', $key)) {
    exit('Login Failed');
}

执行此代码时出现以下错误

未找到“PublicKeyLoader”类

I am trying to connect SSH to EC2 server with privatekey using php (phpseclib). I've downloaded phpseclib from GitHub and added into libraries folder.

My code:

/* $dir --- contains my library folder path */
include($dir.'phpseclib3/Net/SSH2.php');
include($dir.'phpseclib3/Crypt/PublicKeyLoader.php');
$key = new PublicKeyLoader();
$key->loadPrivateKey(file_get_contents($ppkpath));

$ssh = new SSH2('ec2-xx-xxx-xxx-xxx.compute-1.amazonaws.com');
if (!$ssh->login('ec2-user', $key)) {
    exit('Login Failed');
}

while executing this I got the following error

Class 'PublicKeyLoader' not found

您不加载名称空间。

$key = new phpseclib3\Crypt\PublicKeyLoader();

如果您与 Composer 一起安装它，那么最好包含 Composer 自动加载器。

include_once('vendor/autoload.php');

然后使用 use 语句将类加载到当前名称空间中。

use phpseclib3\Crypt\PublicKeyLoader;

这样你的代码就会变成：

include_once('vendor/autoload.php');

use phpseclib3\Crypt\PublicKeyLoader;
use phpseclib3\Net\SSH2;

$key = new PublicKeyLoader();
$key->loadPrivateKey(file_get_contents($ppkpath));

$ssh = new SSH2('ec2-xx-xxx-xxx-xxx.compute-1.amazonaws.com');
if (!$ssh->login('ec2-user', $key)) {
    exit('Login Failed');
}

You don't load the namespace.

$key = new phpseclib3\Crypt\PublicKeyLoader();

Better would it be if you installed it with composer is that you include the composer autoloader.

include_once('vendor/autoload.php');

And then load the class in your current namespace with the use statement.

use phpseclib3\Crypt\PublicKeyLoader;

That way your code would become:

include_once('vendor/autoload.php');

use phpseclib3\Crypt\PublicKeyLoader;
use phpseclib3\Net\SSH2;

$key = new PublicKeyLoader();
$key->loadPrivateKey(file_get_contents($ppkpath));

$ssh = new SSH2('ec2-xx-xxx-xxx-xxx.compute-1.amazonaws.com');
if (!$ssh->login('ec2-user', $key)) {
    exit('Login Failed');
}

我按照@Tschallacka 所说尝试过。效果很好。但我稍微改变了代码如下。

include_once('vendor/autoload.php');

use phpseclib3\Crypt\PublicKeyLoader;
use phpseclib3\Net\SSH2;

$key = PublicKeyLoader::load(file_get_contents($ppkpath));

$ssh = new SSH2('ec2-xx-xxx-xxx-xxx.compute-1.amazonaws.com');
if (!$ssh->login('ec2-user', $key)) {
    exit('Login Failed');
}

I tried as @Tschallacka said. It works fine. But slightly I rechange the code as follows.

include_once('vendor/autoload.php');

use phpseclib3\Crypt\PublicKeyLoader;
use phpseclib3\Net\SSH2;

$key = PublicKeyLoader::load(file_get_contents($ppkpath));

$ssh = new SSH2('ec2-xx-xxx-xxx-xxx.compute-1.amazonaws.com');
if (!$ssh->login('ec2-user', $key)) {
    exit('Login Failed');
}
