GetBucketCorsCommand

This operation is not supported for directory buckets.

Returns the Cross-Origin Resource Sharing (CORS) configuration information set for the bucket.

To use this operation, you must have permission to perform the s3:GetBucketCORS action. By default, the bucket owner has this permission and can grant it to others.

When you use this API operation with an access point, provide the alias of the access point in place of the bucket name.

When you use this API operation with an Object Lambda access point, provide the alias of the Object Lambda access point in place of the bucket name. If the Object Lambda access point alias in a request is not valid, the error code InvalidAccessPointAliasError is returned. For more information about InvalidAccessPointAliasError, see List of Error Codes .

For more information about CORS, see Enabling Cross-Origin Resource Sharing .

Use a bare-bones client and the command you need to make an API call.

const client = new S3Client(config);
const input = { // GetBucketCorsRequest
  Bucket: "STRING_VALUE", // required
  ExpectedBucketOwner: "STRING_VALUE",
};
const command = new GetBucketCorsCommand(input);
const response = await client.send(command);
