我正在尝试通过使用phpseclib在laravel 5.7框架上运行的Web应用程序测试SFTP连接。这是验证码，仅使用密码验证。 SFTP服务器还使用IP白名单作为附加安全性。
$sftp = new SFTP(env('SFTP_HOST'));
if (!$sftp->login(env('SFTP_USER'), env('SFTP_PASSWORD'))) {
echo $sftp->getLog();
}
以及结果日志

奇怪的是，当我在测试服务器内SSH（它的IP被列入白名单）并直接在终端内使用相同的用户名和密码进行SFTP连接时，登录正常，但没有问题，但是通过phpseclib失败，我有也尝试使用Laravel的League / flysystem-sftp，但同样失败。任何人都有任何线索可能有什么问题吗？

它曾经工作的前一天不知道现在发生了什么，即使SSH / SFTP从我的测试服务器到SFTP服务器（该服务器属于一个外部组织）也失败了，不确定他们端是否有任何更改会验证。
这是从我的测试服务器到sftp服务器的完整sftp连接日志。

-vvv日志几乎使我想知道服务器是否正在使用多因素身份验证。就像您必须同时提供RSA密钥和密码一样。如果是这样，您应该能够这样实现：
$key = new RSA;
$key->loadKey(file_get_contents('/home/forge/.ssh/id_rsa'));
$sftp = new SFTP(env('SFTP_HOST'));
if (!$sftp->login(env('SFTP_USER'), $key, env('SFTP_PASSWORD'))) {
echo $sftp->getLog();
}
-vvv日志还表明它正在直接跳至键盘交互式身份验证-甚至没有尝试进行密码身份验证。您可以通过执行$sftp->login(env('SFTP_USER'), ['Password:' => env('SFTP_PASSWORD')])而不是您正在执行的操作来强制phpseclib进行键盘交互。
也许这两个技巧的组合会帮助您。
