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