在prestashop 1.6中从http HTTP / 1.1 200更改为HTTP / 1.1 202

Question

我正在尝试处理脚本，根据需求，在获取xml查询后必须返回HTTP / 1.1 202的答案，但它返回200个答案，是否可以理解是什么原因？

<?php

if ( isset( $_POST['xml'] ) ) {
$respond = stripslashes( $_POST['xml'] );
$xml = simplexml_load_string($respond ); 
$cart = new Cart($xml->order_number);
$currency = new Currency( intval( $cart->id_currency ) );
if ($currency->iso_code != 'RUB')
    exit; 
$sign_bank = Configuration::get('shopexample_av_sign');
$shop_id = Configuration::get('shopexample_shop_id');
$signature = strtoupper( md5( strtoupper( md5($sign_bank) . md5( $shop_id .    (string)$xml->order_number . (string)$xml->amount ) ) ) );
    if ( $signature == $xml->signature ) {
    $amount_paid = (int)$xml->amount / 100;
    $avangard->validateOrder( $cart->id, _PS_OS_PAYMENT_, $amount_paid,  $avangard->displayName, NULL, NULL );
    $order = new Order( $avangard->currentOrder );
    if ( $avangard->setStatus( $xml->ticket, $xml->status_desc ) )
        unlink( dirname(__FILE__).'/'.INPUT_FILENAME );
    header("HTTP/1.1 202 ACCEPTED");
  }
}
else {
Tools::redirectLink(__PS_BASE_URI__.'order.php');
}

?>
