CURLINFO_REDIRECT_URL explained

Name

CURLINFO_REDIRECT_URL - get the URL a redirect would go to

Synopsis

#include <curl/curl.h>
 
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_REDIRECT_URL, char **urlp);

Description

Pass a pointer to a char pointer to receive the URL a redirect would take you to if you would enable CURLOPT_FOLLOWLOCATION. This can come handy if you think using the built-in libcurl redirect logic is not good enough for you but you would still prefer to avoid implementing all the magic of figuring out the new URL.

This URL is also set if the CURLOPT_MAXREDIRS limit prevented a redirect to happen (since 7.54.1).

Protocols

This functionality affects http only

Example

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

Availability

Added in curl 7.18.2

Return value

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