看一個具體的例子：

https://github.com/SAP/spartacus/issues/11730

backport of #11744 to maintanance branch

As described in the Angular docs, a HttpResponse.url can be null or string. Therefore it should be checked in the AnonymousConsentsInterceptor before accessing it with startsWith.

By the way, now we export AnonymousConsentsInterceptor in the public API. There is no reason to hide it in the private API.

因為根據Angular文檔，url 可以為null，因此在調用其方法之前，要先檢查其是否可用。

關于TypeScript雙問號的用法，請查看我這篇TypeScript里的空值合并運算符(雙問號)用法.

在index.ts里，將AnonymousConsentsInterceptor使用export暴露給外部消費者即可。

關于 Spartacus API place order (下單) 的問題：

How are transactions handled in Spartacus? How many API requests are launched to create the order? If we use a WAF with Rate Limiting feature enabled, if one of the order related API request gets blocked is there any risk of payment not appearing to be created which could cause customer resending payment request, hence causing duplicated payments?

回復：

should be just one request in the end to place the order based on all the previously captured products, coupon, payment, addresses, shipping method, … which have more interaction bases APIs
so no worries, there should not be such an edge case as you explained, unless SPA is miss-customised
