Deleting a CORS Rule (SDK for Java)
Function
CORS is a browser-standard mechanism defined by the W3C. It allows a web client in one origin to interact with resources in another. For general web page requests, website scripts and contents in one origin cannot interact with those in another due to SOPs. OBS supports CORS, allowing the resources in OBS to be requested across origins.
This API deletes the CORS rules of a bucket.
If you have any questions during development, post them on the Issues page of GitHub.
Restrictions
- To delete the CORS configuration of a bucket, you must be the bucket owner or have the required permission (obs:bucket:PutBucketCORS in IAM or PutBucketCORS in a bucket policy). For details, see Introduction to OBS Access Control, IAM Custom Policies, and Creating a Custom Bucket Policy.
- The mapping between OBS regions and endpoints must comply with what is listed in Regions and Endpoints.
Method
