You can just use ngx_lua's ngx.location.capure() API function to
capture the subrequest's response. See
https://github.com/chaoslawful/lua-nginx-module#ngxlocationcapture
and also
https://github.com/agentzh/lua-rds-parser#readme
Because you'll be using Lua, you're recommended to switch over to
lua-resty-mysql instead, which is more flexible:
https://github.com/agentzh/lua-resty-mysql
BTW, you're recommended to join the openresty-en mailing list for such
questions: https://groups.google.com/group/openresty-en I'm cc'ing
this list :)
