使用 phpseclib 时的意外行为 [英] Unexpected behavior when using phpseclib

问题描述

我最近尝试实现 phpseclib 库以登录 SFTP 服务器以列​​出目录中的所有文件并下载它们.下载后，将它们移动到服务器上的不同目录.

I've recently tried to implement the phpseclib library to log into a SFTP server to list all the files in a directory and download them. After downloading them, move them to a different directory on the server.

我运气不好...所以直接从 他们的网站上遵循代码，但添加了日志记录.

I'm not having much luck... So following the code straight from their site, but added logging.

set_include_path(get_include_path() . PATH_SEPARATOR . 'phpseclib');

require('Net\SSH2.php');
require('Crypt\RSA.php');   

define('NET_SSH2_LOGGING', 2);
$ssh = new Net_SSH2('host_name', 'port');
$key = new Crypt_RSA();
$key->loadKey(file_get_contents('path_to_rsa_file'));
if (!$ssh->login('username', $key)) {
  exit('Login Failed');
}

$ssh->exec("pwd");

这会导致以下错误:

Unable to request pseudo-terminal

诚然，这是一个较旧的版本，我不确定到底是哪个版本，所以我想也许我应该更新一下.通过 Composer 获取最新版本并运行与上述相同的代码后，我没有收到任何错误，但我在日志中看到了这一点:

Admittedly this is an older version, I'm not sure exactly which one, so I thought maybe I should update. After pulling in the latest version via composer, and running the same code as above, I get no errors, but I get this in the logs:

<- NET_SSH2_MSG_USERAUTH_SUCCESS (since last: 0.1395, network: 0.1394s)

00000000  00:00:00:00                                      ....

有人有什么想法吗?我也尝试过使用 SFTP 类，但由于其他问题注意:连接过早关闭"而失败.

Any one have any ideas? I've also tried using the SFTP class, but it failed with other problems "Notice: Connection closed prematurely".

感谢您的帮助！

推荐答案

看起来服务器不支持 exec().read()/write():

Looks like the server just doesn't support exec(). You might have better luck with read() / write():

至于 SFTP...我需要查看日志才能有任何想法.

As for SFTP... I'd need to see logs to have any ideas.
