CURLINFO_EFFECTIVE_URL - Man Page

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_EFFECTIVE_URL, char **urlp);

Pass in a pointer to a char pointer and get the last used effective URL.

In cases when you have asked libcurl to follow redirects, it may not be the same value you set with CURLOPT_URL(3).

The urlp 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.

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