如何序列化phpseclib? [英] how to serialize phpseclib?

问题描述

我一直在尝试序列化 phpseclib 连接，因为我正在从 ajax 加载一些 php 页面，我不想一次又一次地重新连接.

I have been trying to serialize phpseclib connection since I am loading some php pages from ajax and I dont want to reconnect again and again.

第 1 页 - 首先定义 SSH2

require("Net/SSH2.php");
session_start();
$ssh = new Net_SSH2 ("localhost");
if ($ssh->login($username, $pass)) {
$_SESSION['obj'] = serialize($ssh);

}else{
echo "Invalid Login !!!";
}

第 2 页 - 通过反序列化获取存储的会话

session_start();
require("Net/SSH2.php");
$ssh = unserialize($_SESSION['obj']);
echo $ssh->exec('ls');

我也想将登录信息放在 $_SESSION['obj'] 中，所以每当我在那个 php 页面上时，我只是 $ssh = unserialize($_SESSION['obj']); 然后 $ssh->exec('pwd') ..

I want to put Login information in $_SESSION['obj'] too so Whenever I am on that php page i just $ssh = unserialize($_SESSION['obj']); and then $ssh->exec('pwd') ..

是否有解决办法，或者每当我在那个 PHP 页面上时，我都必须始终连接/登录到 Net/SSH2.php ???

Is there work around or will I have to always connect/login to Net/SSH2.php whenever I am on that PHP page ???

推荐答案

拥有持久连接的唯一方法是实际让脚本不断运行以保持连接打开.这意味着您有一个带有永无止境的 while (true) { ... } 循环的脚本，它打开一次连接并保持它.然后，您需要找到一种与此脚本通信的方法，以使其执行命令.AMQP、ØMQ、Gearman、套接字和类似技术可以用于此目的.

The only way to have a persistent connection is to actually have a script constantly running which is keeping the connection open. Which means you have one script with a never ending while (true) { ... } loop which opens a connection once and keeps it. You then need to find a way to communicate with this script to make it execute commands. AMQP, ØMQ, Gearman, sockets and similar techniques can be employed for that.
