Manpages - CURLINFO_EFFECTIVE_URL.3

CURLINFO_EFFECTIVE_URL - get the last used URL

#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.

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_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);
  }
