Angular2 CORS access-Control-allow-headers

Question

Edit: Realized my mistake. "Access-Control-Allow-Request-Headers" should be "Access-Control-Allow-Headers"

I am trying to use a get api with a header, but I keep getting Request header field Authorization is not allowed by Access-Control-Allow-Headers in preflight response.

I am using angular2 and calling a webapi using asp.net on an iis10 server

I edited my IIS10 already, and I edited the web.config... What else can I do?

The error message talks about a header named Access-Control-Allow-Headers while you set the Access-Control-Allow-Request-Headers in the config file.

I'd also suggest considering moving the CORS configuration in the Web API config as it's a matter related to your application.

*sigh.. "Access-Control-Allow-Request-Headers" should really be

"Access-Control-Allow-Headers"
