Deleting the CORS Configuration of a Bucket

Functions

This operation is used to delete the CORS configuration of a bucket. After the CORS configuration is deleted, the bucket and objects in it cannot be accessed by requests from other websites.

To perform this operation, you must have the PutBucketCORS permission.

Authorization Information

To call this API, you must be the bucket owner or have the permission to delete the CORS configuration of a bucket. You are advised to use IAM or bucket policies for authorization. For details about OBS authorization methods, see Differences Between OBS Permissions Control Methods.

• If you use IAM for authorization, you need to use either role/policy-based authorization or identity policy-based authorization and configure the required permissions:
  • If you use role/policy-based authorization (IAM v3 APIs in the old IAM version), you need to grant the obs:bucket:PutBucketCORS permission. For details, see Creating a Custom IAM Policy.
  • If you use identity policy-based authorization (IAM v5 APIs in the new IAM version), you need to grant the obs:bucket:putBucketCORS permission, as shown in the following table. For details, see Creating a Custom IAM Identity Policy.

    Action	Access Level	Resource Type (*: Required)	Condition Key	Alias	Dependencies
    obs:bucket:putBucketCORS	Write	bucket *	g:EnterpriseProjectId g:ResourceTag/<tag-key>	-	-
    		-	obs:EpochTime obs:SourceIp obs:TlsVersion obs:CustomDomain

• If you use bucket policies for authorization, you need to grant the obs:bucket:PutBucketCORS permission. For details, see Creating a Custom Bucket Policy.
