php - 扩展 prestashop webservice 资源

标签 php web-services api prestashop

我正在尝试扩展 carts多一个字段的资源应该输出 Cart::getSummaryDetails 的结果称呼。我延长了 CartCore类添加新的参数和相应的方法是这样的:

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"?>

            <summary nodeType="cart_summary" api="summary">

                ... <!-- and so on -->
            </summary>
        </associations>
    </cart>
</carts>
</prestashop>

但我得到 <summary>[Array]</summary>或 xml 解析错误。

我尝试添加的另一种方式 cart_summary是创造CartSummary需要的对象 $webserviceParameters领域。但是我不知道如何从这个字段中获取值以及如何关联这个 cart_summary对象 carts资源。

最佳答案

好吧，调试是 Elixir 。事实证明，扩展 carts 资源比我想象的要容易一些。 首先，不需要制作任何额外的资源。我们唯一需要做的就是列出我们需要的字段并为它们设置 getter。我的扩展 Cart 类:

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 对象的设置。 默认情况下，Prestashop 为字段 cart_summary 搜索 getter getWsCartSummary()。如果您有 any_other 字段，它将是 getWsAnyOther()。

我得到的结果:
