通过AJAX调用访问Ruby中的通用FTP连接资源池的方法？ [英] A way to access common FTP connection resource pool in Ruby across AJAX calls?

问题描述

我有一个Web应用程序与外部服务器建立许多FTP或SFTP连接。它的接口使用AJAX，通过AJAX我在远程FTP服务器上获取文件列表并返回到客户端浏览器。

I have a web application which establishes many FTP or SFTP connections with outside servers. Its interface uses AJAX, and via AJAX I get file listings on remote FTP servers and return those to the client browser.

每次运行AJAX调用时，重新连接到远程服务器并重新进行身份验证。这需要额外的时间。

Each time I run an AJAX call, I have to reconnect to the remote server and reauthenticate. This takes a ton of extra time.

有一种方式，我可以以某种方式存储FTP连接资源对象在一些公共内存池和重新访问连接资源对象与未来的AJAX调用？我试过Memcached，但它看起来像是不可能存储连接资源。也许我可以将它们存储在一个线程，以某种方式访问​​他们在那里？任何其他想法？

Is there a way I can somehow store FTP connection resource objects in some common memory pool and re-access to the connection resource objects with future AJAX calls? I tried Memcached, but it looks like it's not possible to store connection resources there. Maybe I could store them in a thread and somehow access them there? Any other ideas?

我总是可以有一个守护程序管理连接并充当代理，但是感觉过分。

I could always have a daemon manage connections and act as a proxy, but that feels overkill.

推荐答案

我最后使用全局变量（例如$ my_global）。我有一个ConnectionPooler单例类管理存储在哈希中的连接。很容易做馅饼。

I ended up making this work using global variables (eg. $my_global). I have a ConnectionPooler singleton class which manages connections stored in a hash. Easy as pie.
