关于在python CGI中获取客户端ip地址

Question

I am trying to get the original client ip address in a python cgi script. The client connect to the web server with a proxy. Following code always returns the proxy ip address. I tested all the env variable, HTTP_CLIENT_IP and HTTP_X_FORWARDED_FOR all return None. Is there any other way to get the client ip behind a proxy? like can I read the http header in a python cgi?

ipaddr = (getenv("HTTP_CLIENT_IP") or
getenv("HTTP_X_FORWARDED_FOR") or
getenv("REMOTE_ADDR") or
"UNKNOWN")

Answer 1

Do you want to:

• find the client's IP address in the headers

• use some sort of javascript to tell you?

For the former, you need the proxy to give you the client address.
Have you tried cgi.print_environ_usage() and looking for the IP address?
