我猜终端经过F5访问Server吧？那就需要在F5上开x-forwarded-for，然后才能用request.getHeader("x-forwarded-for")拿到终端的IP
获取不到IP有可能是客户端不是http请求：建议你 public String getIpAddr(HttpServletRequest request) { String ip = request.getHeader("x-forwarded-for");if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("http_client_ip");} if ...
request.getHeader("x-forwarded-for")这是什么意思 request.getHeader,简单的说就是获取请求的头部信息,根据http协议,它能获取到用户访问链接的信息,以下是我们常用的: request.getHeader("referer"),它主要是用于获取链接的上一个引用。比如,从a.jsp跳转到b.jsp,那在b.jsp中获取到的引用就是a.jsp,如果手动刷...

使用场景:nginx+tomcat,nginx起反向代理作用,由于没有做以下配置,结果在tomcat部署的jia-web通过request.getHeader("X-Forwarded-For")总是返回127.0.0.1: 代码语言:javascript 复制 server{listen80;server_name xx.com;proxy_set_headerX-Real-IP$remote_addr;proxy_set_headerX-Forwarded-For $proxy_add_x_for...
可以使用`request.getHeaderNames()`获取所有请求头的名称列表,然后通过`request.getHeader(String name)`来获取特定请求头的值。 ### 示例代码: ```java Enumeration<String> headerNames = request... java获取ip地址示例 if (request.getHeader("x-forwarded-for") == null) { return request.getR...
原因出在了Squid上。squid.conf 的配制文件 forwarded_for 项默认是为on,如果 forwarded_for 设成了 off 则:X-Forwarded-For: unknown 于是可得出获得客户端真实IP地址的方法二: public String getIpAddr(HttpServletRequest request) { String ip = request.getHeader("x-forwarded-for");...
