CURLOPT_COOKIELIST - add to or manipulate cookies held in memory
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIELIST, char *cookie);
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 will also enable the cookie engine. This adds that single cookie to the internal cookie store.
If you use the Set-Cookie format and don't specify a domain then the cookie is sent for any domain and will not be modified. If a server sets a cookie of the same name (or maybe you've imported one) then both will be sent on a future transfer to that server, likely not what you intended. Either set a domain in Set-Cookie (doing that will include sub domains) or use the Netscape format as shown in EXAMPLE.
Starting in 7.43.0 the aforementioned any-domain cookies will not appear in the lists exported by CURLINFO_COOKIELIST(3) and CURLOPT_COOKIEJAR.
Additionally, there are commands available that perform actions if you pass in these exact strings:
erases all cookies held in memory
erases all session cookies held in memory
writes all known cookies to the file specified by CURLOPT_COOKIEJAR
loads all cookies from the files specified by CURLOPT_COOKIEFILE
/* This example shows an inline import of a cookie in Netscape format. You can set the cookie as HttpOnly to prevent XSS attacks by prepending #HttpOnly_ to the hostname. That may be useful if the cookie will later be imported by a browser. */ #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 will 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 won't be 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 */ res = curl_easy_perform(curl); /* cookies imported from cookies.txt */ curl_easy_cleanup(curl); /* cookies exported to cookies.txt */
