我几乎肯定做了一些愚蠢的事 - 或者说不做我应该做的事情。我正在编写一个插件来通过http POST公开一个函数,所以我可以将JSON发送到我的wordpress应用程序并将其存储在数据库中。我正在使用WP REST API插件并遵循“添加自定义端点”指南http://v2.wp-api.org/extending/adding/
我的插件如下: -
# Exit if accessed directly
if ( ! defined( 'ABSPATH' ) ) {
exit;
}
require_once(ABSPATH . 'wp-content/plugins/rest-api/plugin.php');
require_once(dirname(__FILE__) . '/classes/myPlugin.php');
require_once(dirname(__FILE__) . '/classes/myController.php');
// Action hook to initialize the plugin
add_action('rest_api_init', array('myPlugin_Class', 'init' ));
register_activation_hook(__FILE__, array('myPlugin_Class', 'on_activation'));
register_deactivation_hook(__FILE__, array('myPlugin_Class', 'on_deactivation'));
register_uninstall_hook(__FILE__, array('myPlugin_Class', 'on_uninstall'));
myPlugin_Class只是主要插件位的封装...它包含对静态类myController的引用,它扩展了WP_REST_Controller。插件类摘录及其init方法和构造函数如下: -
class MyPlugin_Class
{
private static $instance;
private static $myController = null;
public static function init()
{
if(self::$instance == null) {
self::$instance = new MyPlugin_Class();
}
return self::$instance;
}
private function __construct()
{
Static::$myController = MyController::init();
Static::$myController->register_routes();
flush_rewrite_rules();
}
public static function on_activation()
{
Static::init();
if ( ! current_user_can( 'activate_plugins' ) )
return;
$plugin = isset( $_REQUEST['plugin'] ) ? $_REQUEST['plugin'] : '';
check_admin_referer( "activate-plugin_{$plugin}" );
//Register routes and don't forget to flush
$this->myController->register_routes();
flush_rewrite_rules();
}
}
Controller类摘录如下: -
class MyController extends WP_REST_Controller {
private static $instance;
private $namespace = 'api/vendor/v1';
private $base = 'default';
private function __construct(){
}
public static function init() {
if(self::$instance == null) {
self::$instance = new MyController();
}
return self::$instance;
}
/**
* Register the routes for the objects of the controller.
*/
public function register_routes() {
$base = $this->default-base;
register_rest_route( $this->namespace, '/' . $base, array(
array(
'methods' => WP_REST_Server::READABLE,
'callback' => array( $this, 'get_items' ),
'permission_callback' => array( $this, 'get_items_permissions_check' ),
'args' => array(
),
),
array(
'methods' => WP_REST_Server::CREATABLE,
'callback' => array( $this, 'create_item' ),
'permission_callback' => array( $this, 'create_item_permissions_check' ),
'args' => $this->get_endpoint_args_for_item_schema( true ),
),
) );
}
}
我无法获得注册路线。激活后,在对register_rest_route的调用中,我收到错误: -
Fatal error: Call to a member function register_route() on null in .../wp-content/plugins/rest-api/plugin.php on line 92
REST API插件中的函数register_route()
function register_rest_route( $namespace, $route, $args = array(), $override = false ) {
/** @var WP_REST_Server $wp_rest_server */
global $wp_rest_server;
if ( isset( $args['callback'] ) ) {
// Upgrade a single set to multiple
$args = array( $args );
}
$defaults = array(
'methods' => 'GET',
'callback' => null,
'args' => array(),
);
foreach ( $args as $key => &$arg_group ) {
if ( ! is_numeric( $arg_group ) ) {
// Route option, skip here
continue;
}
$arg_group = array_merge( $defaults, $arg_group );
}
if ( $namespace ) {
$full_route = '/' . trim( $namespace, '/' ) . '/' . trim( $route, '/' );
} else {
// Non-namespaced routes are not allowed, with the exception of the main
// and namespace indexes. If you really need to register a
// non-namespaced route, call `WP_REST_Server::register_route` directly.
_doing_it_wrong( 'register_rest_route', 'Routes must be namespaced with plugin name and version', 'WPAPI-2.0' );
$full_route = '/' . trim( $route, '/' );
}
$wp_rest_server->register_route( $namespace, $full_route, $args, $override );
}
这个全局$ wp_rest_server在哪里创建(或者我的情况下没有创建)?
即。我忘记做了什么?
加分问题:
我应该在rest_api_init挂钩,register_activation_hook或两者中调用flush_rewrite_rules()吗?
答案 0 :(得分:0)
您对add_action('rest_api_init', array('myPlugin_Class', 'init' ));
的来电很晚,而且在插件激活挂钩之前
register_activation_hook(__FILE__, array('myPlugin_Class', 'on_activation'));
正在接受调用。因此无效。
