php - WP 休息 API : new route return rest_invalid_handler

Question

这是一个用于创建新路由的简单测试脚本:

add_action( 'rest_api_init', function () {
  register_rest_route( 'ass', '/ativar', array(
    'methods' => 'GET',
    'callback' => 'testing_route',
  ) );
} );

function testing_route($data){
    return array( 'message' => 'testing route' );
}

但它返回错误信息:

rest_invalid_handler

Answer 1

解决了!

'callback' => __NAMESPACE__ . '\\testing_route',
