Looking for a way to dump the request information (headers, etc) during an HTTPD request to the output response body (IDFGH-15185)

Is your feature request related to a problem?

I've been building up an ASP like HTTP server framework for ESP32s. I've been relying on the HTTPD facilities in the ESP-IDF instead of rolling my own.
However, I've hit a hard wall.
I need the request headers. All of them.
In fact, I need the entire request, not something I need to play go-fish with.

How do I enumerate every request header from httpd_req_t?

Describe the solution you'd like.

I just want a way to get the entire HTTP request packet, whether i have to parse it myself, or whether through the HTTPD facilities. If there's a way to do it, the documentation isn't saying.

Describe alternatives you've considered.

I've considered eliminating asynchronicity in my responses, and just forwarding requests from headers to httpd_req_t, but this kills performance, and just forwards the same problem to my end user.

Additional context.

Hi @codewitch-honey-crisis, you do not need to parse anything the httpd will parse it itself (you can refer httpd_parse.c file). And regarding dumping all the header information in response body. In the URI handler, you can get the information regarding the request like query params, methods, headers, URI. Thus just provide all these information in the response body. For this you can refer http_server/simple example, refer how the handlers are used and how to output the response.

I realize it parses itself. And then it makes you play go fish with the result. I can't play go fish. I need to know what headers there are. Anyway, I ended up copying a private struct from the ESP-IDF header files and using that to get at the request info. It's less than ideal of course, but Espressif in their infinite wisdom decided I'd never need to enumerate the headers.

Adding a way to enumerate the headers (e.g. httpd_req_get_hdr_count, httpd_req_get_hdr_name, or something iterator-based) would help in what you were trying to do, is that right?
