Amazon S3 image CORS issue

' from origin 'http://example.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://example.com' is therefore not allowed access.

I am using amazon cloudfront for CDN. can someone please tell me why i am still not able to see Access-Control-Allow-Origin:"*"?

Solution

  • This is my setup, you need both edit the CORS in S3 as well in the CloudFront

    <?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<CORSRule>
    <AllowedOrigin>*</AllowedOrigin>
    <AllowedMethod>GET</AllowedMethod>
    <AllowedMethod>HEAD</AllowedMethod>
    <MaxAgeSeconds>3000</MaxAgeSeconds>
    <AllowedHeader>*</AllowedHeader>
</CORSRule>
</CORSConfiguration>

    I don't know if it's part of the protocol, but it's the only way I could set up for a CORS call

    you also need to whitelist the Origin of your CDN behavior

    like:
