nng_http_req_set_data - set HTTP request body

NAME

nng_http_req_set_data − set HTTP request body

SYNOPSIS

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

int nng_http_req_set_data(nng_http_req *req, const void *body, size_t size);

The nng_http_req_set_data() sets the HTTP body associated with the request req to body, and the size of the body to size. This body data will be automatically sent with the request when it is sent using nng_http_conn_write_req().

This also updates the relevant Content−Length header of req.

Note

The current framework does not support sending data via chunked transfer−encoding.

The body is not copied, and the caller must ensure that it is available until the req is deallocated.

Tip

To have a local copy allocated with req that will be automatically deallocated when req is freed, see nng_http_req_copy_data().

Tip

It is a good idea to also set the Content−Type header.

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.
