azure - 如何将 access-control-allow-origin header 从 Web 应用程序转发到前门？

Question

我目前有一个在容器中运行的 Web 应用程序，并在其上正确配置了 access-control-allow-origin header 。但是，当我检查此 Web 应用程序前面的前门时，相同的 header 具有选项“*”——接受所有类型的请求，与配置的请求不同。

如何让前门传播此 Web 应用 header ？

这是关于此的官方文档:Azure Front Door Rule Set

On Azure Front Door, you can create a rule in the Azure Front DoorRules Set to check the Origin header on the request. If it's a validorigin, your rule will set the Access-Control-Allow-Origin header withthe correct value. In this case, the Access-Control-Allow-Originheader from the file's origin server is ignored and the AFD's rulesengine completely manages the allowed CORS origins.
