尝试使用phpseclib在PHP中进行简单的SFTP文件传输。这是代码：
<?php
ini_set('display_errors', '1');
error_reporting(E_ALL);
include_once ('Net/SFTP.php');
define('NET_SSH2_LOGGING', NET_SSH2_LOG_COMPLEX);
$sftp = new Net_SFTP("foo.example.com");
if (!$sftp->login("username", "password")) {
echo($sftp->getLog());
exit('Login Failed');
}
echo($sftp->getLog());
$sftp->get("remotefile.txt", "localfile.txt");
?>
它可以在任何地方完美运行，但需要在Windows / Apache机器上运行。在Windows上，它会在传入的NET_SSH2_MSG_SERVICE_REQUEST处死亡。没有返回错误，但登录失败。每个人都在运行Apache 2.2和PHP 5.3。
这是日志：

问题在于它试图使用的算法之一。在Windows服务器上同时提供aes128-cbc和aes256-cbc时，它会被阻塞。将它们注释掉可以完成连接而不会出错：
在_key_exchange()中的Net / SSH2.php中：
//'aes128-cbc', // RECOMMENDED AES with a 128-bit key
'aes192-cbc', // OPTIONAL AES with a 192-bit key
//'aes256-cbc', // OPTIONAL AES in CBC mode, with a 256-bit key
