CURLINFO_EFFECTIVE_URL(3) Introduction to Library Functions

NAME

CURLINFO_EFFECTIVE_URL - get the last used URL

SYNOPSIS

#include <curl/curl.h>

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

DESCRIPTION

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 is NULL or points to private memory. You MUST NOT
free - it gets freed when you call curl_easy_cleanup(3) on the
corresponding curl handle.

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");
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);
}
}

AVAILABILITY

Added in curl 7.4

RETURN VALUE

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

occurred, see libcurl-errors(3).
