cpp-netlib | The C++ Network Library Project | HTTP library

I created an HTTP listener that accepts POST requests for files. I followed this template almost exactly: https://github.com/cpp-netlib/cpp-netlib/blob/main/libs/network/example/http/echo_async_server.cpp

I start my listener like so: ./build/http_listener 0.0.0.0 8000

Then post file to the listener using curl: curl --form "fileupload=@file1.txt" -X POST http://127.0.0.1:8000/

I noticed that the variable body__, which gets populated with the text of the file also gets populated with header data. I do not want this. How do I populate the variable body__ without any header data?

This is what it looks like:
