tomcat 获取Nginx的真实用户IP

需要：添加 proxy_set_header X-Real-IP $remote_addr;

upstream tomcat_server { 
            server localhost:8080 weight=1;
    } 

    server {
        listen       80;
        server_name 192.168.40.116;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

	location ~* "\.(jsp|do)$" { #当请求的是jsp或do文件时直接到tomcat上去取
     	 	#root  html;
      	 	#index index.html index.htm;
         	#proxy_pass http://192.168.18.201/;
          	proxy_pass http://tomcat_server;
		client_max_body_size     2048m;
       		client_body_buffer_size  128k;
       		proxy_connect_timeout    600;
       		proxy_read_timeout       600;
       		proxy_send_timeout       6000;
       		proxy_buffer_size        16k;
       		proxy_buffers            64k;
       		proxy_busy_buffers_size 64k;
       		proxy_temp_file_write_size 64k;
        }

        location / {
           #发布目录/data/www 
        #    root   /home/ding/ITsoftware/tomcat/webapps/100mshCloud;
	#   fastcgi_pass   192.168.40.116:8080;
  	   proxy_set_header  X-Real-IP  $remote_addr;  
 	   proxy_pass http://tomcat_server/; #注释默认两行，新增一行。
        #    index  index.html index.htm;
        }

tomcat 获取：

public static String getRemoteAddrIp(HttpServletRequest request) {  
    String ipFromNginx = getHeader(request, "X-Real-IP");  
    System.out.println("ipFromNginx:" + ipFromNginx);  
    System.out.println("getRemoteAddr:" + request.getRemoteAddr());  
    return StringUtil.isEmpty(ipFromNginx) ? request.getRemoteAddr() : ipFromNginx;  
}  
  
  
private static String getHeader(HttpServletRequest request, String headName) {  
    String value = request.getHeader(headName);  
    return !StringUtils.isBlank(value) && !"unknown".equalsIgnoreCase(value) ? value : "";  
}  

以上就介绍了tomcat 获取Nginx的真实用户IP，包括了方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
