【问题描述】：

我正在尝试创建一个自定义 Woocommerce 支付网关，将客户重定向到支付网关页面以完成结帐，我正在使用process_payment 代码，如下所示：

    public function process_payment( $order_id )
    {
        global $woocommerce;

        // we need it to get any order details
        $order = wc_get_order( $order_id );

        //setting up needed variables for POST
        $moovpay = new MoovPaySDK;
        $paymentURL = //payment gateway API URL;
        $time = date('YmdHis');
        $secretKey = $this->private_key;
        $merchant_code = $this->merchant_code;
        $mid = $this->mid;
        $orderID = zeroise($order_id, 8);
        $backend_URL = //callback_URL;
        $order_amount = $order->get_total();
        $order_amount_CNY = wc_format_decimal( $order_amount * 5, 2 );;
        $order_amount_CNY_no_dot = str_replace(".", "", $order_amount_CNY);
        //initiate payment
        $response = $moovpay->purchase($secretKey, '', $backend_URL, $merchant_code, $mid, $orderID, $time, '', $order_amount_CNY_no_dot, '');

API 会返回此响应（我删除了这些值）：

如何使用响应重定向到支付网关？我不确定以前是否有人问过这个问题，但我似乎找不到任何解决方案。任何帮助或指导将不胜感激。

我设法让它工作，我会在这里发布我的答案，以防有人需要解决这个问题。

我所做的是将响应输出到 php 文件，然后使用它执行重定向。

public function process_payment( $order_id )
{
  global $woocommerce;
  
  // we need it to get any order details
  $order = wc_get_order( $order_id );
  
  //setting up needed variables for POST
  $moovpay = new MoovPaySDK;
  $paymentURL = ''; //payment gateway API URL;
  $time = date('YmdHis');
  $secretKey = $this->private_key;
  $merchant_code = $this->merchant_code;
  $mid = $this->mid;
  $orderID = zeroise($order_id, 8);
  $backend_URL = '' //callback_URL;
  $order_amount = $order->get_total();
  $order_amount_CNY = wc_format_decimal( $order_amount * 5, 2 );;
  $order_amount_CNY_no_dot = str_replace(".", "", $order_amount_CNY);
  //initiate payment
  $response = $moovpay->purchase($secretKey, '', $backend_URL, $merchant_code, $mid, $orderID, $time, '', $order_amount_CNY_no_dot, '');
  $fh = fopen(plugin_dir_path(__FILE__).'redirect.php', 'w+');
  fwrite($fh, $response);
  fclose($fh);
  $redirect_url = plugin_dir_url(__FILE__).'redirect.php';
  
  return array(
    'result' => 'success',
    'redirect' => $redirect_url
  );
}
