cors

问题 I created REST API using AWS API Gateway & AWS Lambda and when I configured CORS I faced with such issue - I was able to configure CORS response headers for OPTIONS method, but didn't for GET method. I made it according Amazon documentation, but when I called GET method I didn't see required headers (Access-Control-Allow-Methods, Access-Control-Allow-Headers, Access-Control-Allow-Origin) in response.

问题 I am trying to setup 2 CORS policies. One as an api default and the other to use on Controllers as I need them. The reason I want to do this is because I have an endpoint that takes in an object with email info and sends an email (to use with the contact me box on my webpage) and have it only accept requests from my domain.
