使用 Ajax、jQuery、Java 读写文本文件
我需要在服务器端读取和写入大量文本文件。
我们如何使用 Ajax、Java 进行编写...对这些技术知之甚少，但我只需要一个想法来实现。之后我觉得我可以继续了。请你帮助我好吗？

首先，文本文件必须可供公众访问。它们不能存在于服务器上的私有上下文中，因为 JavaScript 是一种客户端技术。
一旦它们公开，您只需对文件位置执行 AJAX 请求，然后根据需要解析它们。
如果将它们放在公共位置会成为问题，那么您将需要一个仅向经过身份验证的帐户提供它们的页面，因此只有登录的人才能查看它们。这意味着它们必须在某个时刻通过服务器端脚本提供服务，然后 AJAX 请求可以根据需要获取该脚本。
但是，如果您采用这种方法，您不妨去掉 AJAX，只让服务器端脚本为您进行处理并输出结果。
Firstly the text files are going to have to be publicly accessible. They cannot exist in a private context on the server, as JavaScript is a client side technology.
Once they are public, you can simply do an AJAX request on the file location, and then parse them as required.
If having them in a public location is going to be a problem, you will need to have a page that serves them to authenticated accounts only, so only people that are logged in can view them. This means they will have to be served via a server side script at some point, which the AJAX request can then fetch as required.
However if you take this approach, you might as well take out the AJAX and just have the server side script do the processing for you and feed out the result.
