CURLOPT_NOBODY(3) Introduction to Library Functions CURLOPT_NOBODY(3)

NAME

CURLOPT_NOBODY - do the download request without getting the body

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_NOBODY, long opt);

DESCRIPTION

A long parameter set to 1 tells libcurl to not include the body-part
in the output when doing what would otherwise be a download. For
HTTP(S), this makes libcurl do a HEAD request. For most other
protocols it means just not asking to transfer the body data.

For HTTP operations when CURLOPT_NOBODY(3) has been set, disabling
this option (with 0) makes it a GET again - only if the method is
still set to be HEAD. The proper way to get back to a GET request is
to set CURLOPT_HTTPGET(3) and for other methods, use the POST or
UPLOAD options.

Enabling CURLOPT_NOBODY(3) means asking for a download without a
body.

If you do a transfer with HTTP that involves a method other than
HEAD, you get a body (unless the resource and server sends a zero
byte body for the specific URL you request).

DEFAULT

0, the body is transferred

PROTOCOLS

This functionality affects all supported protocols

EXAMPLE

int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

/* get us the resource without a body - use HEAD */
curl_easy_setopt(curl, CURLOPT_NOBODY, 1L);

/* Perform the request */
curl_easy_perform(curl);
}
}

AVAILABILITY

Added in curl 7.1

RETURN VALUE

curl_easy_setopt(3) returns a CURLcode indicating success or error.

CURLE_OK (0) means everything was OK, non-zero means an error
occurred, see libcurl-errors(3).
