Possible to get fd from ngx.req.socket

the last script is dynamic-ssl.lua script that I have changed it to load the default crt and key files when there is no any key or crt files to load!

Possible to get fd from ngx.req.socket

Is it possible to get the socket filedescriptor from ngx.req.socket?

Would like to use ffi to do:

getsockopt(fd, SOL_SOCKET, SO_PEERCRED, &ucred, &len)

Hello!

No. There is no way to achieve this, but you can code some C APIs by yourself.

There is a related PR that you may be interested in:

However, as agentzh said, exposing the underlying fd could break some
encapsulation behavior, so beware.
