3 kinds of API requests to the server
1. // Request for a full page from the theme
kickpress_is_fullpage();
2. // Request for a page fragment via Ajax
kickpress_is_ajax();
3. // Remote API request or action
kickpress_is_remote_api();
1. Full Page Requests
Triggering the KickPress API
{site}.com/how-to/ {Archive page for custom post type called “How To”}
{site}.com/how-to/api/add/
{site}.com/how-to/api/save/
{site}.com/how-to/using-powerpoint/api/edit/
More Examples:
{site}.com/2012/02/18/wordcamp/api/edit/
{site}.com/2012/02/18/wordcamp/api/save/
{site}.com/2012/02/18/wordcamp/api/delete/
{site}.com/2012/02/18/wordcamp/api/bookmark/
{site}.com/2012/02/18/wordcamp/api/add_term[category]/featured/
API Parameters are appended to the end of the standard WordPress permalinks:
2. Ajax Requests
Theme Modifications Add an extra conditional comment to the top of these theme files:
header.php footer.php sidebar.php
<?php
if ( kickpress_is_ajax() ) { return; }
?>
Theme Modifications Add a conditional blocks for any code that should be ignored on AJAX requests:
<?php get_header(); ?>
<?php if ( kickpress_is_fullpage() ) : ?>
<div id="content-wrapper">
<?php endif; ?>
<?php $post_type = get_post_type(); ?>
<?php get_template_part( 'loop', $post_type ); ?>
<?php $args = array( 'post_type', $post_type );
<?php kickpress_ajax_reload( $args, 'content-wrapper‘ ); ?>
<?php kickpress_is_fullpage( '</div>‘ ); ?>
<?php get_sidebar(); ?>
<?php get_footer(); ?>
3. Remote API Requests
Authentication
Photo by Jon Worth
Every registered user is assigned a “token” and a “secret” to be used in generating signatures for making ReSTful OAuth style API calls to the Web App.
Authentication credentials are available on the user’s profile page
$token = '{token-from-profile-page}';
$secret = '{secret-from-profile-page}';
$timestamp = time();
$method = 'GET';
$host = 'www.{your domain}.com';
// Create the string to sign
$string_to_sign = $method . "\n" . $host . "\n" . $timestamp . "\n";
// Calculate signature with SHA1 and base64-encoding
$signature = base64_encode(
hash_hmac( 'sha1', $string_to_sign, $secret, true )
);
$authentication_params = array(
'signature' => $signature,
'timestamp' => $timestamp,
'token' => $token
);
// Normalize the query string parameters
$query_parts = normalized_query_parameters( $authentication_params );
$query_string = implode('&', $query_parts);
// Build the URL for the remote API request
$url = 'http://' . $host . '/{post type}/api/{action}/?' . $query_string;
