Policy Syntax
CAM policy:
{     
        "version":"2.0", 
        "statement": 
        [ 
           { 
              "effect":"effect", 
              "action":["action"], 
              "resource":["resource"], 
               "condition": {"key":{"value"}} 
           } 
       ] 
}
version is required. Currently, only the "2.0" value is allowed.
statement describes the details of one or more permissions. This element contains a permission or permission set of other elements such as effect, action, resource, and condition. Each policy has one statement element.
1.1 action describes the action to be allowed or denied. An action can be an API (described using the prefix "name") or a feature set (a set of specific APIs described with the prefix "permid"). This element is required.
1.2 resource describes the details of authorization. A resource is described in a six-piece format. Detailed resource definitions vary by product. For more information on how to specify a resource, see the documentation for the product whose resources you are writing a statement for. This element is required.
1.3 condition describes the condition for the policy to take effect. A condition consists of an operator, an action key, and an action value. A condition value may contain information such as the time and IP address. Some services allow you to specify additional values in a condition. This element is optional.
1.4 effect describes whether the result produced by the statement is "allow" or "deny". This element is required.
VPC Operations
In the statement of a CAM policy, you can specify any API action from any service that supports CAM. For VPC, use APIs with the prefix "name/vpc:", for example, name/vpc:Describe or name/vpc:CreateRoute.
To specify multiple actions in a single statement, separate them with commas, as shown below:
"action":["name/vpc:action1","name/vpc:action2"]
You can also specify multiple actions by using a wildcard. For example, you can specify all actions whose names begin with "Describe", as shown below:
"action":["name/vpc:Describe*"]
To specify all actions in VPC, use the wildcard "*" as follows:
"action": ["name/vpc:*"]
VPC Resource Paths
Each CAM policy statement has its own resources.
The general format of a resource path is as follows:
****qcs**:project_id:service_type:region:account:resource**
project_id: project information. This element is only used to enable compatibility with legacy CAM logic and can be left empty.
service_type: the product abbreviation, such as VPC.
region: region information, such as bj.
account: the root account of the resource owner, such as uin/164256472.
resource: resource details of each product, such as vpc/vpc_id1 or vpc/*.
For example, you can specify an instance (vpc-d08sl2zr in this case) in the statement, as shown below:
"resource":[ "qcs::vpc:bj:uin/164256472:instance/vpc-d08sl2zr"]
You can also use the wildcard "*" to specify all instances under a specific account, as shown below:
"resource":[ "qcs::vpc:bj:uin/164256472:instance/*"]
To specify all resources or if any API action does not support resource-level permissions, you can use the wildcard "*" in the Resource element, as shown below:
"resource": ["*"]
To specify multiple resources in one instruction, separate them with commas. In the following example, two resources are specified:
"resource":["resource1","resource2"]
The following table describes the resources that can be used by VPC and the corresponding methods of describing these resources.
In the following table, the words prefixed with "$" are all alternative names.
project indicates the project ID.
region indicates the region.
account indicates the account ID.
