我创建了一个名为 delivery_date 的新自定义订单属性，并在销售订单网格中显示了相同的属性，但我没有在我的订单 Api 响应中获取自定义属性。

我得到的错误是致命错误：未捕获的错误：调用未定义的方法 Magento\Sales\Api\Data\OrderExtension::setTipAndTrickAttribute()

请帮忙。

要回答有关错误的问题，您使用了错误的魔术功能。您对该属性的神奇功能是setDeliveryDate().

您还需要确保您的 events.xml 具有适合观察者的类。

<observer name="sales_order_load_delivery_date" instance="Magestore\TipAndTrick\Observer\Sales\OrderLoadAfter" />

虽然您的观察者课程是：Amos\CustomOrder\Observer\Sales\OrderLoadAfter

当您使用示例材料时，请不要忘记在需要时更改类、命名空间和函数名称等。您可能还需要一个订单存储库插件才能将其实际放入 API 响应中。

<type name="Magento\Sales\Api\OrderRepositoryInterface">
    <plugin name="your_name_here_extension_attribute"
                type="<Vendor>\<Module>\Plugin\OrderRepositoryPlugin" />
</type>
