wordpress - Woocommerce 限制 API

Question

我在使用 Wocommerce API 时遇到了一些问题。我知道这并不理想，但我使用一个唯一键来读取/写入我网站上的一些资源。为了防止有人使用密钥获取其他用户的数据，我编写了一个函数，在登录时生成一个唯一令牌，每个请求都需要该令牌，然后使用rest_pre_dispatch过滤器对其进行验证。它有效，但不幸的是，该过滤器没有有关请求的详细信息，因此我正在尝试找到一种更实用的方法来做到这一点。我在GitHub 问题上找到了以下代码：

class App_API_Validation {

  public function __construct(){
        add_filter( 'woocommerce_api_create_order_data', array( $this, 'validate_customer_on_resource_creation' ), 999999 );
        add_filter( 'woocommerce_api_dispatch_args', array( $this, 'validate_request' ), 999999 );
  }
    /**
     * Validate REST API's request
     *
     * It is hooked on 'woocommerce_api_dispatch_args' filter.
     * With our custom validation we ensure that user has access
     * only to his resources, which means:
     * #1 - User doesn't have access ability to make CRUD operations to other users profiles
     * #2 - User doesn't have access to others users resources (we are validating ownership)
     * #3 - User doesn't have access to any resource list - for example to get all customers or orders.
     *
     * @param array $args Data sent by REST API client
     * @param array $callback Function to process REST API's request

问题是过滤器woocommerce_api_dispatch_args没有被调用，所以没有任何工作了。你有什么想法让这项工作再次发挥作用吗？谢谢！
