== NAME
|
|
|
|
nng_http_res_get_header - return HTTP response header
|
|
|
|
== SYNOPSIS
|
|
|
|
[source, c]
|
|
----
|
|
#include <nng/nng.h>
|
|
#include <nng/supplemental/http/http.h>
|
|
|
|
const char *nng_http_res_get_header(nng_http_res *res, const char *key);
|
|
----
|
|
|
|
== DESCRIPTION
|
|
|
|
The `nng_http_res_get_header()` looks for an HTTP header _key_ in
|
|
the response _res_, and returns the associated value if found,
|
|
or `NULL` if not found.
|
|
|
|
The value of _key_ is case insensitive, and 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.
|
|
|
|
|
|
== RETURN VALUES
|
|
|
|
HTTP header value for _key_, if it exists, or NULL otherwise.
|
|
|
|
== ERRORS
|
|
|
|
None.
