启用CORS不在全球范围内工作

Question

In my Web API project I have enabled CORS globally by adding following line in WebApiConfig

config.EnableCors();

but it still give me error while I request service from other App Domain.

However it works fine if I apply [EnableCors("*", "*", "*")] on controller level.

Why it doesn't work for application level?

If you want to define a global rule, you can pass that into EnableCors :

EnableCorsAttribute cors = new EnableCorsAttribute("*", "*", "*");
config.EnableCors(cors);

By calling EnableCors , you just enable the framework, nothing more.
