== 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
|
||
|
xref:nng_http_req_get_method.3http.adoc[`nng_http_req_get_method()`] function.
|
||
|
|
||
|
== RETURN VALUES
|
||
|
|
||
|
This function returns 0 on success, and non-zero otherwise.
|
||
|
|
||
|
== ERRORS
