CURLOPT_NOBODY - do the download request without getting the body

#include <curl/curl.h>

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

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, unsetting the option (with 0) will make 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 will get a body (unless the resource and server sends a zero byte body for the specific URL you request).

0, the body is transferred

Most

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); }

Always

Returns CURLE_OK
