nginx获取真实客户端ip实现过程
作者：YiJavaMan
这段文章介绍了如何配置Nginx作为反向代理服务器以获取真实客户端IP,并并提供了在Java程序中通过特定头部获取该IP的方法;强调了配置Nginx以实现反向代理和获取真实IP的重要性
nginx作为反向代理服务器，即代理我们的服务端，下面介绍下如何配置nginx获取真实的客户端ip
1、配置nginx.con
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
proxy_pass http://127.0.0.1:8080;
root html;
index index.html index.htm;
#获取真实ip配置
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
2、在java程序中可以通过如下方式获取
@GetMapping(value = "/getRealIp")
public String getRealIp(){
log.info(request.getRemoteAddr());
log.info(request.getRequestURL().toString());
log.info("端口" + request.getRemotePort() + "");
log.info("======================");
log.info("真实ip：{}",getClientIP());
return request.getRemoteAddr() + "\n" +
request.getRequestURL();
}
/***
* 获取客户端IP地址;这里通过了Nginx获取;X-Real-IP
*/
public String getClientIP() {
String fromSource = "X-Real-IP";
String ip = request.getHeader("X-Real-IP");
log.info("X-Real-IP 初始化值的ip:{} ", ip);
// if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("X-Forwarded-For");
fromSource = "X-Forwarded-For";
log.info("X-Forwarded-For赋值成功ip:{} ", ip);
// }
// if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("Proxy-Client-IP");
fromSource = "Proxy-Client-IP";
log.info("Proxy-Client-IP赋值成功ip:{} ", ip);
// }
// if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("WL-Proxy-Client-IP");
fromSource = "WL-Proxy-Client-IP";
log.info("WL-Proxy-Client-IP赋值成功ip:{} ", ip);
// }
// if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getRemoteAddr();
fromSource = "request.getRemoteAddr";
log.info("RemoteAddr赋值成功ip:{} ", ip);
// }
return ip;
}这样就可以打印出真实ip了！
即request.getHeader("X-Real-IP")的值
总结
