The enterprise account, CompanyExample (ownerUin: 12345678; appID: 1250000000), has a sub-account, Developer, that requires read permissions for files under the dir1 directory of the Bucket1 bucket of the COS service in Shanghai region under the CompanyExample enterprise account.

Solution A:

Step 1: create the following policy by using policy syntax.

    "version": "2.0",
         "effect": "allow",
         "action":  [
         "resource": "qcs::cos:ap-shanghai:uid/1250000000:Bucket1-1250000000/dir1/*"

Step 2: associate the sub-account with the policy. To learn how to associate a policy with a user account, see Authorization Management.

Solution B:

Configure the policy and ACL in the COS Console. For more information, see the COS documentation.
