WooCommerce REST API v2：如何处理付款？

  由于helgatheviking同意，目前还没有办法使用WooCommerce REST API处理订单付款 .

  我最终在 woocommerce_api_create_order 过滤器中写了一个钩子，它在创建订单时立即处理付款订单 . 如果处理失败，则将错误添加到 order->post->post_excerpt 字段，使其在JSON响应中显示为 order->note .

  为此，我还必须扩展支付网关，以便其 process_payment() 方法接受 $user_id 作为输入 . 这是因为它是开箱即用的，可以对当前登录的用户进行操作，在我的情况下，在大多数情况下，可能是REST客户端登录的系统用户，而不是实际用户进行购买 .

  扩展网关的另一个好处是，现在可以返回错误而不是写入 wc_add_notice() . 由于这是一个REST服务，所以没有看到 wc_add_notice() 的输出

  add_filter('woocommerce_api_create_order', 'acme_on_api_create_order', 10, 3);
  
  /**
   * When order is created in REST client, actually make them pay for it
   * @param int $id order id
   * @param array $data order data posted by client
   * @param WC_API_Orders $api not used
   * @return array the data passed back unaltered
   */
  function acme_on_api_create_order($id, $data, $api) {
      if($data['payment_details']['method_id'] == 'acme_rest_gateway') {
          $order = wc_get_order($id);
          $order->calculate_totals();
          $acme_gateway = new WC_Acme_Gateway_For_Rest();
          $payment = $acme_gateway->process_payment($id, $data['customer_id']);
          if($payment["result"] == "success") {
              $order->update_status('completed');
          }
          else {
              $order->update_status("cancelled");
              wp_update_post(array(
                  'ID' => $id,
                  'post_excerpt' => json_encode($payment)
              ));
          }
      }
      return $data;
  }
  
  // Register the payment gateway
  add_filter('woocommerce_payment_gateways', 'acme_add_payment_gateway_class');
  
  function acme_add_payment_gateway_class($methods) {
      $methods[] = 'WC_Acme_Gateway_For_Rest';
      return $methods;
  }
  
  // Load the new payment gateway needed by REST client
  add_action('after_setup_theme', 'acme_init_rest_gateway_class');
  
  function acme_init_rest_gateway_class() {
  
      /**
       * Extend the payment gateway to work in the REST API context
       */
      class WC_Acme_Gateway_For_Rest extends WC_Acme_Gateway {
  
          /**
           * Constructor for the gateway.
           */
          public function __construct() {
              parent::__construct();
              $this->id = 'acme_rest_gateway';
          }
  
          /**
           * Process Payment. This is the same as the parent::process_payment($order_id) except that we're also passing

          function process_payment($order_id, $user_id) {
                  $order = wc_get_order( $order_id );
              /* 
               * todo: code sending da moneez to da bank

                  return array(
                      'result'   => 'success',
                      'redirect' => $this->get_return_url( $order )
                  );
          }
      }
  }

  谢谢你给我的方向 .

  我做了一些改动和简化的步骤 .

  如下：

  add_filter('woocommerce_api_order_response', 'intercept_api_response', 1, 4);
  /**
  * Here, intercept api's response to include the url of payment
  **/
  function intercept_api_response($order_data, $order)
  {
      $order_data['payment_url'] = $order->payment_url;
  
      return $order_data;
  }
  
  add_filter('woocommerce_api_create_order', 'intercept_on_api_create_order', 10, 3);
  
  
  function intercept_on_api_create_order($id, $data, $api)
  {
      if (in_array($data['payment_details']['method_id'], ['pagseguro', 'paypal'])) {
          $order = wc_get_order($id);
          $order->calculate_totals();
  
          if ($data['payment_details']['method_id'] == 'paypal') {
              $paypal = new WC_Gateway_Paypal();
              $payment = $paypal->process_payment($id);
          }
          update_post_meta($id, '_payment_url', $payment['redirect']);
      }
      return $payment;
  }
  

  我希望这可以帮助别人 . 经过大量的反复试验，这是一项艰苦的工作 .
