java web判斷服務器是不是本機

1,如何獲取瀏覽器的ip

Java代碼  

1. /*** 
2.      * 獲取客戶端ip地址(能夠穿透代理) 
3.      * @param request 
4.      * @return  
5.      */  
6.     public static String getClientIpAddr(HttpServletRequest request) {    
7.         String ip = request.getHeader("X-Forwarded-For");    
8.         if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {    
9.             ip = request.getHeader("Proxy-Client-IP");    
10.         }    
11.         if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {    
12.             ip = request.getHeader("WL-Proxy-Client-IP");    
13.         }    
14.         if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {    
15.             ip = request.getHeader("HTTP_X_FORWARDED_FOR");    
16.         }    
17.         if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {    
18.             ip = request.getHeader("HTTP_X_FORWARDED");    
19.         }    
20.         if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {    
21.             ip = request.getHeader("HTTP_X_CLUSTER_CLIENT_IP");    
22.         }    
23.         if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {    
24.             ip = request.getHeader("HTTP_CLIENT_IP");    
25.         }    
26.         if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {    
27.             ip = request.getHeader("HTTP_FORWARDED_FOR");    
28.         }    
29.         if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {    
30.             ip = request.getHeader("HTTP_FORWARDED");    
31.         }    
32.         if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {    
33.             ip = request.getHeader("HTTP_VIA");    
34.         }    
35.         if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {    
36.             ip = request.getHeader("REMOTE_ADDR");    
37.         }    
38.         if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {    
39.             ip = request.getRemoteAddr();    
40.         }    
41.         return ip;    
42.     }  
43.     public static String getIpAddr(HttpServletRequest request) {  
44.         String ip = request.getHeader("X-Real-IP");  
45.         if (null != ip && !"".equals(ip.trim())  
46.                 && !"unknown".equalsIgnoreCase(ip)) {  
47.             return ip;  
48.         }  
49.         ip = request.getHeader("X-Forwarded-For");  
50.         if (null != ip && !"".equals(ip.trim())  
51.                 && !"unknown".equalsIgnoreCase(ip)) {  
52.             // get first ip from proxy ip  
53.             int index = ip.indexOf(',');  
54.             if (index != -1) {  
55.                 return ip.substring(0, index);  
56.             } else {  
57.                 return ip;  
58.             }  
59.         }  
60.         return request.getRemoteAddr();  
61.     }  

 

 

2,如何判斷服務器是不是本機

Java代碼  

1. /*** 
2.      * 服務器是不是本機 
3.      * @param request 
4.      * @return  
5.      */  
6.     public static boolean isLocalIp(HttpServletRequest request){  
7.         String ip=WebServletUtil.getClientIpAddr(request);  
8.         return ip.equals("127.0.0.1")||ip.equals("localhost")||ip.equals("0:0:0:0:0:0:0:1");  
9.     }  

 3,應用:

Java代碼  

1. /*** 
2.      * favicon.ico  
3.      * @throws IOException  
4.      */  
5.     @RequestMapping(value = "/favicon.ico")  
6.     public ResponseEntity<byte[]> faviconIco(HttpServletRequest request) throws IOException {  
7.         HttpHeaders headers = new HttpHeaders();  
8.         headers.setContentType(MediaType.IMAGE_PNG);  
9.         String faviconIcoName="sms-4.ico";  
10.         headers.set(Constant2.CONTENT_DISPOSITION,WebServletUtil.getContentDisposition(true, faviconIcoName));  
11.         ///home/whuang/software/apache-tomcat-7.0.53/webapps/ROOT/  
12.         String webappPath=null;  
13.         if(WebServletUtil.isLocalIp(request)){//服務器在本機(訪問ip爲127或localhost)  
14.             webappPath=WebServletUtil.getRealPath(request);  
15.         }else{  
16.             webappPath=DictionaryParam.get(Constant2.DICTIONARY_GROUP_GLOBAL_SETTING, "WEB-INF_LOC");  
17.         }  
18.         return new ResponseEntity<byte[]>(FileUtils.getBytes4File(  
19.                 webappPath  
20.                 +"WEB-INF/static/img/"+faviconIcoName),  
21.                                           headers, HttpStatus.CREATED);  
22.   
23.     }  

 

4,如何獲取服務器部署的本地路徑

Java代碼  

1. public static String getRealPath(HttpServletRequest request) {  
2.         return getRealPath(request,  "\\");  
3.     }  
4.     /** 
5.      * 獲取相對地址的絕對地址 
6.      *  
7.      * @param request 
8.      * @param relativePath 
9.      * @return 
10.      */  
11.     public static String getRealPath(HttpServletRequest request, String relativePath) {  
12.         return request.getSession().getServletContext().getRealPath(relativePath);  
13.     }
