CURLOPT_NOBODY explained

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 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 and for other methods, use the POST or UPLOAD options.

Enabling CURLOPT_NOBODY 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);
  }
}
