== NAME

nng_http_handler_set_method - set HTTP handler method

== SYNOPSIS

[source, c]
-----------
#include <nng/nng.h>
#include <nng/supplemental/http/http.h>

int nng_http_handler_set_method(nng_http_handler *handler, const char *method);
-----------

== DESCRIPTION

The `nng_http_handler_set_method()` function sets the _method_ that the
_handler_ will be called for, such as "GET" or "POST".  (By default the
"GET" method is handled.)  If _method_ is `NULL`, then the request method
is not examined, and the handler will be executed regardless of the
method.

NOTE: The server will automatically call "GET" handlers if the client
sends a "HEAD" request, and will suppress HTTP body data in the responses
sent for such requests.

NOTE: No validation of the _method_ is performed, but HTTP specifications
insist that the actual method sent over the wire be capitalized.

The handler may always examine the actual method used using the
<<nng_http_req_get_method#,nng_http_req_get_method(3)>> function.

== RETURN VALUES

This function returns 0 on success, and non-zero otherwise.

== ERRORS

`NNG_ENOMEM`:: Insufficient free memory exists.
`NNG_ENOTSUP`:: No support for HTTP in the library.
