how to having tcp socket on body_filter_by_lua_file ?

https://github.com/openresty/lua-nginx-module#ngxsockettcphey guys
I want to create a tcp socket connection inside a lua file...

but my lua file is used on body_filter_by_lua_file tag !
I can see that tcp socket is just supported on rewrite_by_lua*, access_by_lua*, content_by_lua*, ngx.timer.*, ssl_certificate_by_lua*, ssl_session_fetch_by_lua*
https://github.com/openresty/lua-nginx-module#ngxsockettcp

so I want to get a perfect suggestion about calling a method from that lua file to creating a tcp socket connection!
I have to use it on body_filter_by_lua_file but I don't know how to connect to tcp socket from my body_filter_by_lua_file lua!
please help me,

thanks a lot...
Best...

Hello!

As the document mentinos, you cannot use Cosocket in body_filter_by_lua*. What about spawn a timer in body_filter_by_lua* and use Cosocket inside the timer?

Be careful because body filters can run multiple times per request. Caution and good design is needed here.

I used ngx.timer.at inside body_filter_by_lua_file script and then I defined a function which created tcp socket to sending data to the server and now it has no error like that!
so I see that timer can solve calling some classes in unavailable tags...
good luck...
