CURLINFO_REDIRECT_URL(3) Introduction to Library Functions

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(3). 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(3) 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

curl_easy_getinfo(3) returns a CURLcode indicating success or error.

occurred, see libcurl-errors(3).
