### Question
When accessing through IP+port number, the real IP address obtained by the
server is that of the shenyu server
shenyu version: 2.6.0
Use http method to register, websocket to synchronize data, and divide
plug-in method.
Reproduction method:
Request server IP address: 172.17.91.11 intranet
shenyu-gateway server ip address: 172.17.90.58 intranet
Server server IP address: 172.17.90.58
How to get the real IP on the server side:
`
public static String getIpAddr(HttpServletRequest request) {
try {
String ip = request.getHeader("x-forwarded-for");
if (ip == null || ip.length() == 0 ||
(INVALID_URL.equalsIgnoreCase(ip))) {
ip = request.getHeader("Proxy-Client-IP");
}
if (ip == null || ip.length() == 0 ||
(INVALID_URL.equalsIgnoreCase(ip))) {
ip = request.getHeader("WL-Proxy-Client-IP");
}
if (ip == null || ip.length() == 0 ||
(INVALID_URL.equalsIgnoreCase(ip))) {
ip = request.getHeader("X-Real-IP");
}
if (ip == null || ip.length() == 0 ||
(INVALID_URL.equalsIgnoreCase(ip))) {
ip = request.getRemoteAddr();
}
if (ip != null) {
String[] ips = ip.split(",");
ip = ips[0];
}
return ip;
} catch (Exception e) {
log.info("error=>", e);
}
return null;
}`
Reproduction process:
Calling method ==> curl --location
'http://172.17.90.58:9195/user/shenyu/test01'
Expected: The server log prints ip==>172.17.91.11
Actual: The server log prints ip==>172.17.90.58
