我尝试使用另一个字段来扩展carts资源，该字段应输出Cart::getSummaryDetails调用的结果。我已经扩展CartCore类来添加新参数和相应的方法，如下所示：
class Cart extends CartCore
{
protected $webserviceParameters = [
'fields' => [
'id_address_delivery' => ['xlink_resource' => 'addresses'],
'id_address_invoice' => ['xlink_resource' => 'addresses'],
'id_currency' => ['xlink_resource' => 'currencies'],
'id_customer' => ['xlink_resource' => 'customers'],
'id_guest' => ['xlink_resource' => 'guests'],
'id_lang' => ['xlink_resource' => 'languages'],
],
'associations' => [
'cart_rows' => [
'resource' => 'cart_row',
'virtual_entity' => true,
'fields' => [
'id_product' => ['required' => true, 'xlink_resource' => 'products'],
'id_product_attribute' => ['required' => true, 'xlink_resource' => 'combinations'],
'id_address_delivery' => ['required' => true, 'xlink_resource' => 'addresses'],
'quantity' => ['required' => true],
],
],
'summary' => [
'getter' => 'getWsSummaryDetails',
'setter' => false,
'virtual_entity' => true,
],
],
];
public function getWsSummaryDetails()
{
$result = $this->getSummaryDetails(null, true);
unset($result['carrier']);
unset($result['delivery']);
unset($result['invoice']);
return $result;
}
}
预期的输出应该是这样的：
<?xml version="1.0" encoding="UTF-8"?>

但我得到<summary>[Array]</summary>或xml解析错误。
我尝试添加cart_summary的另一种方法是创建包含所需CartSummary字段的$webserviceParameters对象。但我无法了解如何从此字段中获取值以及如何将此cart_summary对象与carts资源相关联。
答案 0 :(得分：0)
嗯，调试是一个灵丹妙药。事实证明，扩展carts资源比我想象的要容易一些。
首先，没有必要提供任何额外的资源。我们唯一需要的是列出我们需要的字段并设置它们的getter。我的扩展Cart课程：
class Cart extends CartCore
{
protected $webserviceParameters = [
'fields' => [
'id_address_delivery' => ['xlink_resource' => 'addresses'],
'id_address_invoice' => ['xlink_resource' => 'addresses'],
'id_currency' => ['xlink_resource' => 'currencies'],
'id_customer' => ['xlink_resource' => 'customers'],
'id_guest' => ['xlink_resource' => 'guests'],
'id_lang' => ['xlink_resource' => 'languages'],
],
'associations' => [
'cart_rows' => [
'resource' => 'cart_row',
'virtual_entity' => true,
'fields' => [
'id_product' => ['required' => true, 'xlink_resource' => 'products'],
'id_product_attribute' => ['required' => true, 'xlink_resource' => 'combinations'],
'id_address_delivery' => ['required' => true, 'xlink_resource' => 'addresses'],
'quantity' => ['required' => true],
],
],
'cart_summary' => [
'resource' => 'cart_summary_row',
'virtual_entity' => true,
'setter' => false,
'fields' => [
'id' => '',
'is_virtual_cart' => '',
'total_discounts' => '',
'total_discounts_tax_exc' => '',
'total_wrapping' => '',
'total_wrapping_tax_exc' => '',
'total_shipping' => '',
'total_shipping_tax_exc' => '',
'total_products_wt' => '',
'total_products' => '',
'total_price' => '',
'total_tax' => '',
'total_price_without_tax' => '',
'is_multi_address_delivery' => '',
'free_ship' => '',
],
],
],
];
/**
* @return array
*/
public function getWsCartSummary()
{
$result = $this->getSummaryDetails(null, true);
unset($result['carrier']);
unset($result['delivery']);
unset($result['invoice']);
$result['id'] = $this->id;
return ['cart_summary' => $result];
}
}
WebserviceOutputBuilder不适合处理对象，它需要制作更复杂的字段列表和getter。我只需要标量值。所以我取消了carrier，delivey和invoice个对象。
Prestashop默认搜索字段getWsCartSummary()的getter cart_summary。如果您有any_other字段，则为getWsAnyOther()。
我得到的结果：
