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

local http = chilkat.Http.new()

-- Use your WordPress login, such as "admin", not the application name.
http.login = "wp_username"
-- Use the application password, such as "Nths RwVH eDJ4 weNZ orMN jabq"
-- See WordPress Application Passwords Plugin
http.password = "app_password"
http.basic_auth = true

-- Note: For this to work, you'll likely need to update your .htaccess file on your WordPress server.
-- Otherwise you'll get this error:
--
-- 401 : Sorry, you are not allowed to create posts as this user
--
-- Your default .htaccess file probably looks like this:
--
-- <IfModule mod_rewrite.c>
-- RewriteEngine On
-- RewriteBase /
-- RewriteRule ^index\.php$ - [L]
-- RewriteCond %{REQUEST_FILENAME} !-f
-- RewriteCond %{REQUEST_FILENAME} !-d
-- RewriteRule . /index.php [L]
-- </IfModule>
-- # END WordPress
--
-- Add the following line immediately after the "RewriteEngine On" line:    RewriteRule .* - [E=REMOTE_USER:%{HTTP:Authorization}]
-- Your .htaccess file should look like this after the edit:
--
-- <IfModule mod_rewrite.c>
-- RewriteEngine On
-- RewriteRule .* - [E=REMOTE_USER:%{HTTP:Authorization}]
-- RewriteBase /
-- RewriteRule ^index\.php$ - [L]
-- RewriteCond %{REQUEST_FILENAME} !-f
-- RewriteCond %{REQUEST_FILENAME} !-d
-- RewriteRule . /index.php [L]
-- </IfModule>
-- # END WordPress
