How to configure bucket's CORS in AWS.

Because we sometimes need cross-domain access.

Please refer to the article:

https://docs.aws.amazon.com/AmazonS3/latest/dev/cors.html#how-do-i-enable-cors

Content.

The following configuration parameters are the configuration parameters of the rule:

<CORSConfiguration>
 <CORSRule>
   <AllowedOrigin>http://www.example1.com</AllowedOrigin>

   <AllowedMethod>PUT</AllowedMethod>
   <AllowedMethod>POST</AllowedMethod>
   <AllowedMethod>DELETE</AllowedMethod>

   <AllowedHeader>*</AllowedHeader>
 </CORSRule>
 <CORSRule>
   <AllowedOrigin>http://www.example2.com</AllowedOrigin>

   <AllowedMethod>PUT</AllowedMethod>
   <AllowedMethod>POST</AllowedMethod>
   <AllowedMethod>DELETE</AllowedMethod>

   <AllowedHeader>*</AllowedHeader>
 </CORSRule>
 <CORSRule>
   <AllowedOrigin>*</AllowedOrigin>
   <AllowedMethod>GET</AllowedMethod>
 </CORSRule>
</CORSConfiguration>

If you want to open to all domain names you visit, you only need to configure one

<AllowedOrigin>*</AllowedOrigin>

The rules are fine.

The specific configuration location is in your bucket.
