📦 version 1.11, in alpine 3.24

okay so bestie, this is the <hotpink>nng_http_req_get_header</hotpink> page from the NNG Reference Manual (3http section), and it’s giving “find me that header value” energy 💅✨

✨ NAME ✨

nng_http_req_get_header — return HTTP request header

🎀 SYNOPSIS 🎀

#include <nng/nng.h>
#include <nng/supplemental/http/http.h>

const char *nng_http_req_get_header(nng_http_req *req, const char *key);

💖 DESCRIPTION 💖

nng_http_req_get_header() looks for an HTTP header key in the request req, and returns the associated value if found, or NULL if not found. no cap 🫶

The key value is case insensitive, and it should not include the final colon in an HTTP header. For example, specifying Host or hOSt are equivalent, whereas the value Host: will not find anything. periodt 💅

🌸 RETURN VALUES 🌸

Returns the HTTP header value for key, if it exists, or NULL otherwise. that’s the whole vibe check 🦋

💀 ERRORS 💀

None. literally no error side quest here, bestie ✨
