Nginx透传获取客户端IP地址_JAVA_编程开发_程序员俱乐部

nginx.conf配置:

?

class="java" name="code">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";
