CURLOPT_COOKIELIST(3) libcurl CURLOPT_COOKIELIST(3)
NAME
CURLOPT_COOKIELIST - add to or manipulate cookies held in memory
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIELIST,
char *cookie);
DESCRIPTION
Pass a char * to a cookie string.
Such a cookie can be either a single line in Netscape / Mozilla format
or just regular HTTP-style header (Set-Cookie: ...) format. This option
also enables the cookie engine. This adds that single cookie to the
internal cookie store.
We strongly advice against loading cookies from a HTTP header file, as
that is an inferior data exchange format.
Exercise caution if you are using this option and multiple transfers
may occur. If you use the Set-Cookie format and the string does not
specify a domain, then the cookie is sent for any domain (even after
redirects are followed) and cannot be modified by a server-set cookie.
If a server sets a cookie of the same name (or maybe you have imported
one) then both are sent on future transfers to that server, likely not
what you intended. To address these issues set a domain in Set-Cookie
(doing that includes subdomains) or much better: use the Netscape file
format.
Additionally, there are commands available that perform actions if you
pass in these exact strings:
ALL erases all cookies held in memory
SESS erases all session cookies held in memory
FLUSH writes all known cookies to the file specified by CURLOPT_COOK-
IEJAR(3)
RELOAD loads all cookies from the files specified by CURLOPT_COOK-
IEFILE(3)
DEFAULT
NULL
PROTOCOLS
HTTP
EXAMPLE
/* an inline import of a cookie in Netscape format. */
#define SEP "\t" /* Tab separates the fields */
char *my_cookie =
"example.com" /* Hostname */
SEP "FALSE" /* Include subdomains */
SEP "/" /* Path */
SEP "FALSE" /* Secure */
SEP "0" /* Expiry in epoch time format. 0 == Session */
SEP "foo" /* Name */
SEP "bar"; /* Value */
/* my_cookie is imported immediately via CURLOPT_COOKIELIST. */
curl_easy_setopt(curl, CURLOPT_COOKIELIST, my_cookie);
/* The list of cookies in cookies.txt are not be imported until right
before a transfer is performed. Cookies in the list that have the same
hostname, path and name as in my_cookie are skipped. That is because
libcurl has already imported my_cookie and it's considered a "live"
cookie. A live cookie is not replaced by one read from a file.
*/
curl_easy_setopt(curl, CURLOPT_COOKIEFILE, "cookies.txt"); /* import */
/* Cookies are exported after curl_easy_cleanup is called. The server
may have added, deleted or modified cookies by then. The cookies that
were skipped on import are not exported.
*/
curl_easy_setopt(curl, CURLOPT_COOKIEJAR, "cookies.txt"); /* export */
curl_easy_perform(curl); /* cookies imported from cookies.txt */
curl_easy_cleanup(curl); /* cookies exported to cookies.txt */
