Logging POST body

[keeyong]

I am using ngixing as a reverse proxy in front of apache (PHP) as a load
balancer and a logger. For some endpoints, I want to log their POST bodies
and I looked up the Web and found some solution requiring to install
HttpEchoModule. Is there any other way of achieving this? Preferably without
installing any new module?
