CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTPGET, long useget);
When setting CURLOPT_HTTPGET(3) to 1, it will automatically set CURLOPT_NOBODY(3) to 0 and CURLOPT_UPLOAD(3) to 0.
Setting this option to zero has no effect. Applications need to explicitly select which HTTP request method to use, they cannot deselect a method. To reset a handle to default method, consider curl_easy_reset(3).
curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
/* use a GET to fetch this */
curl_easy_setopt(curl, CURLOPT_HTTPGET, 1L);
/* Perform the request */
curl_easy_perform(curl);
}
