Magento 2 Klarna结账

Question

我需要将Klarna Checkout模块集成到magento 2.1.2中。我使用的是"klarna/m2-checkout module“的版本: 4.2.2。选择交付方式时，弹出窗口总是会出现错误：

抱歉，无法处理您选择的交付选项。请选择其他传送选项。

当我选择发货方式时，我会得到这样的响应：

这里我不喜欢这个区块：

 "errors": {
        "generic": ["shipping_service_failed"]
    }

有人知道怎么修吗？

传送错误：

Answer 1

当您设置address_update回调和时，会出现此错误，但处理方式不正确。如果您需要更新order的地址，则应设置该回调，并且该回调的时间不超过10秒。

下面是一个例子：https://developers.klarna.com/api/#checkout-api-callbacks-address-update

和一些最佳实践：https://developers.klarna.com/documentation/klarna-checkout/best-practices/#address-updated

Answer 2

如果您在localhost上运行Klarna Checkout，那么您应该使localhost-based应用程序可以通过HTTP协议从Klarna访问(例如，用于address_update回调)。

你可以通过像Ngrok这样的服务做到这一点。
