`lua_need_request_body` ask Nginx to fill `$request_body` variable using nginx-lua	`log_format` specify custom log format to log request body
`$request_body` this variable will contain request body	`content_by_lua` nginx-lua module directive to execute specified Lua code
`ngx.say("ok")` just outputs `ok` so the client gets something in return	`access_log` set access log path and format
`/var/log/nginx/lua.log` path to access log

Usage example

curl localhost --data "test123"
tail /var/log/nginx/lua.log

output

[22/Mar/2022:16:15:22 +0000] "POST / HTTP/1.1" "test123"
