How to create new built-in variables of nginx on openresty?
Because when we use apisix, there are certain requirements for the format
of access.log, and the format needs to be similar to the following:
[$ http_host] [$ route_id] [$ upstream_id] [$ uri] [$ scheme] [rsp_st: $
status] [ups_st: $ upstream_status]
For example, route_id is the id of the route object. This kind of data is
not the default built-in variable of nginx. How can I create the built-in
variable nginx of route_id?

This method is more difficult and less flexible.

Hi, hui,
you can also use `set` of Nginx[1], not only the C module.

In the past, a new built-in nginx variable was implemented through the
nginx c module
For example, define the ngx_http_variable_t nginx built-in variable on the
nginx module, and then set the nginx built-in variable through various ffi
callback methods
The statement is as follows:
{ngx_string ("app_id"), NULL,
ngx_http_appid_variable, 0,
NGX_HTTP_VAR_NOCACHEABLE, 0},

1. we can add a new variable `route_id` in nginx.conf .
2. update it in Lua land.
3. use it in access log format.
