nng_http_req_set_header(3http)

NAME

nng_http_req_set_header - set HTTP request header

SYNOPSIS

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

int nng_http_req_set_header(nng_http_req *req, const char *key,
    const char *val);

DESCRIPTION

The nng_http_req_set_header() sets the HTTP header for the request req and the key to the val. The key and val are copied. Any previous header with the same key is replaced.

See nng_http_req_add_header() to add additional headers with the same key without replacing them.

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: is not a legal header key.

RETURN VALUES

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

ERRORS

NNG_ENOMEM

Insufficient memory to perform the operation.
NNG_ENOTSUP

No support for HTTP in the library.
