问题描述
我已切换为使用Amazon AWS Elastic Load Balancer，现在我获得了$_SERVER['REMOTE_ADDR']的私有IP地址-该地址过去曾为我提供客户端的IP地址.
I've switched to using an Amazon AWS Elastic Load Balancer and now I'm getting a private IP address for $_SERVER['REMOTE_ADDR'] - which used to give me the client's IP address.
我现在如何获取客户端的IP地址?
推荐答案
您的Web服务器从Amazon ELB接收HTTP请求.因此，远程地址将始终是ELB ip地址之一. 如果需要从ELB后面获取远程主机的地址，请从HTTP标头"X-Forwarded-For"中获取.
Your webserver receives HTTP requests from the Amazon ELB. Therefore, the remote address will always be one of the ELB ip addresses. If you need the remote host's address from behind the ELB, get it from HTTP header "X-Forwarded-For".
