Nginx透传获取客户端IP地址

nginx.conf配置:

 

Java代码  

1. location / {   
2.      proxy_pass http://127.0.0.1:8080/myweb/;  
3.      proxy_redirect    off;  
4.      proxy_set_header  Host             $host;  
5.      proxy_set_header  X-Real-IP        $remote_addr;  
6.      proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;  
7. }  

 myweb后端获取方式:

 

Java代码  

1. /*** 
2.  * 获取客户端IP地址;这里通过了Nginx获取;X-Real-IP, 
3.  * @param request 
4.  * @return 
5.  */  
6. public static String getClientIP(HttpServletRequest request) {  
7.     String fromSource = "X-Real-IP";  
8.     String ip = request.getHeader("X-Real-IP");  
9.     if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {  
10.         ip = request.getHeader("X-Forwarded-For");  
11.         fromSource = "X-Forwarded-For";  
12.     }  
13.     if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {  
14.         ip = request.getHeader("Proxy-Client-IP");  
15.         fromSource = "Proxy-Client-IP";  
16.     }  
17.     if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {  
18.         ip = request.getHeader("WL-Proxy-Client-IP");  
19.         fromSource = "WL-Proxy-Client-IP";  
20.     }  
21.     if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {  
22.         ip = request.getRemoteAddr();  
23.         fromSource = "request.getRemoteAddr";  
24.     }  
25.     appLog.info("App Client IP: "+ip+", fromSource: "+fromSource);  
26.     return ip;  
27. }
