CURLINFO_COOKIELIST(3) Library Functions Manual CURLINFO_COOKIELIST(3)

CURLINFO_COOKIELIST - get all known cookies

#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_COOKIELIST,
                           struct curl_slist **cookies);

Pass a pointer to a 'struct curl_slist *' to receive a linked-list of all cookies curl knows (expired ones, too). Do not forget to call curl_slist_free_all(3) on the list after it has been used. If there are no cookies (cookies for the handle have not been enabled or simply none have been received) the 'struct curl_slist *' is made a NULL pointer.

Since 7.43.0 cookies that were imported in the Set-Cookie format without a domain name are not exported by this option.

    /* enable the cookie engine */
    curl_easy_setopt(curl, CURLOPT_COOKIEFILE, "");
    res = curl_easy_perform(curl);
    if(!res) {
      /* extract all known cookies */
      struct curl_slist *cookies = NULL;
      res = curl_easy_getinfo(curl, CURLINFO_COOKIELIST, &cookies);
      if(!res && cookies) {
        /* a linked list of cookies in cookie file format */
        struct curl_slist *each = cookies;
        while(each) {
          printf("%s\n", each->data);
          each = each->next;
        }
        /* we must free these cookies when we are done */
        curl_slist_free_all(cookies);
      }
    }
    curl_easy_cleanup(curl);
  }
}
