I am following this tutorial to create custom end points to WP-API .
I am always getting this error on hitting /wp-json/custom-plugin/v2/get-all-post-ids/ on postman to test :
{
"code": "rest_no_route",
"message": "No route was found matching
the URL and request method ",
"data": {
"status": 404
}
}
I have created a custom-plugin.php file in /plugins/custom-plugin/ directory .
<?php
if ( ! defined( 'ABSPATH' ) ) exit;
add_action( 'rest_api_init', 'dt_register_api_hooks' );
function dt_register_api_hooks() {
register_rest_route( 'custom-plugin/v2', '/get-all-post-ids/', array(
'methods' => 'GET',
'callback' => 'dt_get_all_post_ids',
)
);
}
// Return all post IDs
function dt_get_all_post_ids() {
if ( false === ( $all_post_ids = get_transient( 'dt_all_post_ids' ) ) ) {
$all_post_ids = get_posts( array(
'numberposts' => -1,
'post_type' => 'post',
'fields' => 'ids',
) );
// cache for 2 hours
set_transient( 'dt_all_post_ids', $all_post_ids, 60*60*2 );
}
return $all_post_ids;
}
?>
Ensure your callback to add_action( 'rest_api_init', 'dt_register_api_hooks' );
is being run.
In my case, my callback was not being called because I was using add_action('rest_api_init', ...)
too late; the action had already fired. As in, my call to register_rest_route()
never even happened.
