CURLINFO_EFFECTIVE_METHOD - Man Page

#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 have asked libcurl to follow redirects, the method may not be the same method the first request would use.

The methodp pointer is NULL or points to private memory. You MUST NOT free - it gets freed when you call curl_easy_cleanup(3) on the corresponding CURL handle.

This functionality affects http only

int main(void)
{
  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 curl 7.72.0

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
