问题描述

如何在Java Glassfish的Websocket API中获取远程对等方的IP地址?

How can I get the IP address of the remote peer in Websocket API for Java Glassfish ?

推荐答案

另一种方法，基于

Another method, based on this answer to another question, is to get the headers of the HandshakeRequest. The headers you are looking for are either of the following.

origin: [IP Address]
x-forwarded-for: [Possibly a separate IP]

为清楚起见，这是我的设置以及如何发现它:

Just for clarity, here's my setup, and how I discovered this:

• MyMachine上的Wamp 2.5:6060.这将托管一个客户端HTML页面.
• LabMachine:6060(正常连接)和LabMachine:6443(安全连接)上的Wamp 2.5.这充当代理.
• 在MyMachine:8080(正常)和MyMachine:8181(SSL)上运行的GlassFish 4.0.这是终点.

我通过自己的计算机，实验室计算机和同事的计算机连接到客户端页面.在每种情况下，WebSocket请求的原始标头都是

I connected to the client page via my own machine, the lab machine, and a colleague's machine. In every case, the origin header of the WebSocket request was

http://MyMachine:6060

但是，在每种情况下， x-forwarded-host 标头都不同，与实际客户端的IP地址匹配.

However, in each case the x-forwarded-host header was different, matching the IP addresses of the actual client.
