Error: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource
amazon-s3, axios, get, xmlhttprequest
Solution
`Access-Control-Allow-Origin` is a response header, not a request header. You can't fix this locally, because it's a problem on the other end.
You need CORS (Cross Origin Resource Sharing) enabled and configured on the S3 bucket you are trying to access.

Problem
I requests s3 server through axios, and I got `Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.` Also, before that, I got `OPTIONS https://s3.ap-northeast-2.amazonaws.com/.../... 403 (Forbidden)` I should solve this problem in client-side. I am hosting my files on my local machine. My request codes are below. ``` axios({ url: 'https://s3.ap-northeast-2.amazonaws.com/.../...', method: 'get', withCredentials: true, headers: { 'Content-Type': 'image/jpeg', 'Access-Control-Allow-Origin': 'http://*, https://*', } ``` }) I tried - `start chrome --disable-web-security` using git - Installed chrome plugin - Allow-Control-Allow-Origin: * nothing worked... How can I solve this problem?
