This is a nginx module for log base on ngx_lua_module

syntax: sml_log path [tail=on | off] level

default: sml_log logs/biz.log tail=off info

context: http, server, location

this command record log dispatch from nginx log

NOTE: when a request have debug_uri or debug_header or debug_body, then it can print this information log for online debug

example:

curl localhost:/xxx?debug_uri=true&debug_header=*&debug_body=true

then in lua land

local sml = require "sml"
sml.log(sml.info, ...)

the log will add request uri and all headers and body if have one in the log tail

we also can set debug_header to any header such as host etc...
