支付网关不向 URL 发送请求参数？

Question

这是我的自定义支付网关的以下代码。 当我试图在结帐页面下订单时，它显示连接到我创建的服务器异常。当我们在firebug中检查参数时，它只显示checkout并且响应失败。 我尝试将请求参数发送到网关 URL，但没有成功。 请告诉我我在哪里做错了？ 提前致谢..

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

    // Get this Order's information so that we know
    // who to charge and how much
    $customer_order = new WC_Order( $order_id );

    // Are we testing right now or is it a real transaction
    $environment = ( $this->environment == "yes" ) ? 'TRUE' : 'FALSE';

    // Decide which URL to post to
    $environment_url = ( "FALSE" == $environment ) 
                       ? 'https://www.qpayindia.com/wwws/Payment/PaymentDetails.aspx'
                       : 'https://www.qpayindia.com/wwws/Payment/PaymentDetails.aspx';

    //$r['response_reason_code']      = $resp[2];
    //$r['Message']      = $resp[3];

    // Test the code to know if the transaction went through or not.
    // 1 or 4 means the transaction was a success
    if ( ( $r['ResponseCode'] == 100 )  ) {
        // Payment has been successful
        $customer_order->add_order_note( __( 'Authorize.net payment completed.', 'spyr-authorizenet-aim' ) );

        // Mark order as Paid
        $customer_order->payment_complete();

        // Empty the cart (Very important step)
        $woocommerce->cart->empty_cart();

        // Redirect to thank you page
        return array(
            'result'   => 'success',
            'redirect' => $this->get_return_url( $customer_order ),
        );
    } else {
        // Transaction was not succesful
        // Add notice to the cart
        wc_add_notice( $r['Message'], 'error' );
        // Add note to the order for your reference
        $customer_order->add_order_note( 'Error: '. $r['Message'] );
    }

}

// Validate fields
public function validate_fields() {
    return true;
}

我认为你混淆了这里的逻辑：

if ( is_wp_error( $response ) ) 
    throw new Exception(....);
else
{
    throw new Exception(....); 
}

因此，无论响应如何，您都会抛出异常，这样您就永远不会更深入地访问代码。异常总是会中断当前流程，除非用“try...catch”捕获，否则它会中断程序。为了快速测试，试试这个（顺便注意大括号）：

if ( is_wp_error( $response ) ) {
    throw new Exception( __( 'We are currently experiencing problems trying to connect to this payment gateway. Sorry for the inconvenience.', 'spyr-authorizenet-aim' ) );
} else if ( empty( $response['body'] ) ) {
    throw new Exception( __( 'Authorize.net\'s Response was empty.', 'spyr-authorizenet-aim' ) );
} 

// Retrieve the body's resopnse if no errors found
// ...
