是否可以在C＃中动态启用和禁用CORS？

Question

I have a api method, where it will give some result based on that result I have to conclude whether i have to send the response to the request or not. For that i need to enable CORS at runtime in c#. For each request it should enable or disable CORS . Is this scenario possible in c#?

Answer 1

This seems to be something that needs more work then just some standard configuration using EnableCors attributes as you would normally do.

I would advize to implement a custom CORS policy provider or factory, so you can filter requests on a one-by-one basis. (You just return another policy on the HTTP request.)

More information on implementing such provider or factory can be found in the documentation .
