Hi folks! I've just kicked out OpenResty 1.7.7.1 RC2 for testing: http://openresty.org/download/ngx_openresty-1.7.7.1rc2.tar.gz Changes since the last...

port of nginx http request

Hi,

Is there any ngx lua api to extract the port from the http request.

e.g. in this http proxy request, api should return <port>

"GET https://<host>:<port>/uri?args HTTP/1.1"

I see ngx lua has api to return uri and host with ngx.var.uri and ngx.var.host respectively.

Regards,

Vijay

I think what you need is just the $server_port nginx variable:

http://nginx.org/en/docs/http/ngx_http_core_module.html#var_server_port

All the (indexed) nginx variables can be accessed from within Lua via
the ngx.var API:

I think perhaps you're looking for ngx.var.server_port ?

With ngx.var.* [1] you can read/write to any Nginx variables [2], though you can only write to those which have already been defined.
