# DeleteBucketCors
<a name="API_DeleteBucketCors"></a>

**Note**  
This operation is not supported for directory buckets.

Deletes the `cors` configuration information set for the bucket.

To use this operation, you must have permission to perform the `s3:PutBucketCORS` action. The bucket owner has this permission by default and can grant this permission to others. 

For information about `cors`, see [Enabling Cross-Origin Resource Sharing](https://docs.amazonaws.cn/AmazonS3/latest/dev/cors.html) in the *Amazon S3 User Guide*.

**Important**  
You must URL encode any signed header values that contain spaces. For example, if your header value is `my file.txt`, containing two spaces after `my`, you must URL encode this value to `my%20%20file.txt`.
