CURLINFO_EFFECTIVE_METHOD - get the last used HTTP method

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_EFFECTIVE_METHOD,
 char **methodp);

Pass in a pointer to a char pointer and get the last used effective HTTP method. In cases when you've asked libcurl to follow redirects, the method may very well not be the same method the first request would use. The methodp pointer will be NULL or pointing to private memory you MUST NOT free - it gets freed when you call curl_easy_cleanup(3) on the corresponding CURL handle. HTTP(S)

CURL *curl = curl_easy_init();
if(curl) {
 CURLcode res;
 curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
 curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "data");
 curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
 res = curl_easy_perform(curl);
 if(res == CURLE_OK) {
 char *method = NULL;
 curl_easy_getinfo(curl, CURLINFO_EFFECTIVE_METHOD, &method);
 if(method)
 printf("Redirected to method: %s\\n", method);
 }
 curl_easy_cleanup(curl);
}

Added in 7.72.0 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. curl_easy_getinfo "(3), " curl_easy_setopt "(3), "
