在 WooCommerce 中以编程方式对保存的信用卡收费

我正在 WooCommerce 中以编程方式创建订单，并且需要向默认保存的信用卡收费。我正在使用 WooCommerce stripe 插件，并已弄清楚如何设置正确的付款方式，但无法弄清楚如何实际向卡收费。下面是我到目前为止的代码。

$order = wc_create_order();

$order->add_product( wc_get_product( 52 ), 1 );
$order->set_address( $shipping_address, 'shipping' );
$order->set_address($user_info, 'billing');

$payment_gateways = WC()->payment_gateways->payment_gateways();
$order->set_payment_method($payment_gateways['stripe']);

$order->calculate_totals(); 
$order->update_status("Completed", 'First Partner Order', TRUE);
$order->save();

我找到了一个解决方案，虽然不是很优雅，但似乎可行。 基本前提是我们使用 stripe api 创建费用，然后手动添加所有自定义字段。这将导致成功收费，该费用会反映在 woocommerce 中，并且稍后可以通过管理员退款。下面是带注释的代码。我很想知道是否有人找到了更好的解决方案。

注意：您必须使用条纹 PHP API

$order = wc_create_order();

$order->add_product( wc_get_product( 52 ), 1 ); //Add product to order
$order->set_address( $shipping_address, 'shipping' ); //Add shipping address
$order->set_address($user_info, 'billing'); //Add billing address

//Set payment gateways
$payment_gateways = WC()->payment_gateways->payment_gateways();
$order->set_payment_method($payment_gateways['stripe']);

$order->calculate_totals(true); //setting true included tax 
//Try to charge stripe card
try {

  // Get stripe  test or secret key from woocommerce settings
  $options = get_option( 'woocommerce_stripe_settings' );
  $stripeKey = 'yes' === $options['testmode'] ? $options['test_secret_key'] : 
  $options['secret_key'] ;

  //Set the Stripe API Key
  \Stripe\Stripe::setApiKey($stripeKey);

  //Get Stripe customer token that was created when the card was saved in woo
  $tokenString = get_user_meta($user_id, '_stripe_customer_id', true);

  //Get total for the order as a number
  $total = intval($order->get_total());
  $totalNoDec = $total * 100;

  //Charge user via Stripe API
  $charge = \Stripe\Charge::create([
    'amount' => $totalNoDec,
    'currency' => 'usd',
    'customer' => $tokenString,
  ]);

  //Set all the meta data that will be needed
  $order->update_meta_data( '_transaction_id', $charge->id );
  $order->update_meta_data( '_stripe_source_id', $charge->payment_method );
  $order->update_meta_data( '_stripe_charge_captured', 'yes'  );
  $order->update_meta_data( '_stripe_currency', $charge->currancy);
  $order->update_meta_data( '_stripe_customer_id', $charge->customer);

} catch (\Stripe\Error\Base $e) {
  // Code to do something with the $e exception object when an error occurs
  echo($e->getMessage());
} catch (Exception $e) {
  echo($e->getMessage());
  // Catch any other non-Stripe exceptions
}

//Set order status to processing
$order->set_status("processing");
$order->save();
