nginx.conf配置:
- location / {
- proxy_pass http://127.0.0.1:8080/myweb/;
- proxy_redirect off;
- proxy_set_header Host $host;
- proxy_set_header X-Real-IP $remote_addr;
- proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
- }
myweb后端获取方式:
- /***
- * 获取客户端IP地址;这里通过了Nginx获取;X-Real-IP,
- * @param request
- * @return
- */
- public static String getClientIP(HttpServletRequest request) {
- String fromSource = "X-Real-IP";
- String ip = request.getHeader("X-Real-IP");
- if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
- ip = request.getHeader("X-Forwarded-For");
- fromSource = "X-Forwarded-For";
- }
- if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
- ip = request.getHeader("Proxy-Client-IP");
- fromSource = "Proxy-Client-IP";
- }
- if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
- ip = request.getHeader("WL-Proxy-Client-IP");
- fromSource = "WL-Proxy-Client-IP";
- }
- if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
- ip = request.getRemoteAddr();
- fromSource = "request.getRemoteAddr";
- }
- appLog.info("App Client IP: "+ip+", fromSource: "+fromSource);
- return ip;
- }
