Persist Cookies to XML Files and Auto Re-Send

See more HTTP Examples

Demonstrates how to persist incoming cookies to XML files and automatically re-send in subsesquent HTTP requests. Lua

local chilkat = require("chilkat")

-- This example assumes the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

local http = chilkat.Http.new()

-- To save cookies to XML files (per domain) in a specific
-- directory, set the CookieDir property (the directory must
-- already exist and be writeable by the caller).  Also,
-- set the SaveCookies property:
http.cookie_dir = "/cookieDir"
http.save_cookies = true

-- Any methods that do a GET, POST, etc. will save cookies
-- to the CookieDir:
local html = http:quick_get_str("https://www.paypal.com/")

-- After running this code, a "paypal_com.xml" file should appear
-- in /cookieDir.

-- It's content will look something like this:

-- <cookies>
--     <cookie key=".paypal.com,/" v="0" secure="yes">
--         <navcmd>_home-general</navcmd>
--         <HttpOnly />
--         <cwrClyrK4LoCV1fydGbAxiNL6iG>9cz...</cwrClyrK4LoCV1fydGbAxiNL6iG>
--     </cookie>
-- </cookies>

-- To cause cached cookies to be sent with
-- subsequent HTTP requests, set the SendCookies
-- property = true.
http.send_cookies = true

-- If another HTTP request is sent, the cookies should
-- be added:
html = http:quick_get_str("https://www.paypal.com/")

-- Check the LastHeader property to see the MIME header
-- of the last HTTP request sent.
-- The "Cookie" header field should be present.
print("--- LastHeader ---")
print(http.last_header)
