Creating a Custom Bucket Policy (JSON View)

If you are familiar with the JSON syntax and OBS bucket policies, you can code a bucket policy in the JSON view. There is no limit on the number of bucket policies (statements) for a bucket, but the JSON descriptions of all bucket policies in a bucket cannot exceed 20 KB in total.

Procedure

In the navigation pane of OBS Console, choose Object Storage.
In the bucket list, click the bucket you want to operate to go to the Objects page.
In the navigation pane, choose Permissions > Bucket Policies.
In the upper right corner of the page, click JSON and then Edit.

Edit the bucket policy. Below gives a bucket policy example in JSON:

{
   "Statement":[
       {
           "Action":[
               "CreateBucket",
               "DeleteBucket"
           ],
           "Effect":"Allow",
           "Principal":{
               "ID":[
                   "domain/account ID", 
                   "domain/account ID:user/User ID" 
               ]
           },
           "Condition":{
               "NumericNotEquals":{
                   "Referer":"sdf"
               },
               "StringNotLike":{
                   "Delimiter":"ouio"
               }
           },
           "Resource":"000-02/key01"
       }
   ]
 }
