需要获取用户的公共IP，但获取部署应用程序的服务器的IP [英] need to obtain the public IP of the user but getting the IP of the server where the app is deployed

问题描述

可能重复：

用Java查找您的网站访问者IP地址

我想维护我网站的日志。为此，我需要存储访客的公共IP。我怎样才能做到这一点 ？直到知道我这就是我一直在做的事情：

I want to maintain logs for my website. For that I need to store the public IP of the visitor. How can I do that ? Till know I this was what I have been doing :

         URL ip = new URL("http://api.externalip.net/hostname/");
        BufferedReader br = new BufferedReader(new InputStreamReader(ip.openStream()));
        String publicIP = br.readLine();

但这会返回服务器的IP，我想这是托管页面的位置。例如，我总是得到IP： 76.xxxxxxxx 但是当我从查看时 whatismyip 我有类似 106.xxxxxxx 的内容。

but this returns me the IP of the server , I guess where the page is hosted. For example I always get the IP as : 76.xxxxxxxx but when I check from whatismyip I have something like 106.xxxxxxx .

我如何获得此IP？哪个是访问该网站的用户的公共IP。

How can I get this IP ? Which is the public IP of the user from which it visits the website.

推荐答案

每个请求到您的Web应用程序，客户端的IP也被发送。所以你需要做的就是过滤 请。获取并存储您喜欢的任何信息。

With every Request to your web application, client's IP is sent too. So all you need to do is to have Filter over Requests. Gain and store any information you like.
