    RAM authorization

    The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

    • Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.

    • API: The API that you can call to perform the action.

    • Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.

    • Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.

      • For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.

      • For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.

    • Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.

    • Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

    DataEventSelectors

    string

    The configuration of the data event selector. This parameter is a JSON array that can contain a maximum of 20 elements.

    Each element in the JSON array includes the following elements:

    • ServiceName: The name of the Alibaba Cloud service that supports data events.

    • ReadWriteType: The type of data event. Valid values: Read, Write, and All.

      For example, the following configuration specifies that only GetObject, CopyObject, and AppendObject events are delivered:

      {"EventName":{"Equals":["GetObject","CopyObject","AppendObject"]}}

      If you specify NotEquals, events other than GetObject, CopyObject, and AppendObject are delivered.

    • ResourceArn: This element also contains the Equals and NotEquals fields, similar to EventName. For example:

      {"ResourceArn":{"Equals":[arn1,...,arnx]}}

    [{"EventName":{"Equals":["GetObject","CopyObject","AppendObject"]},"ReadWriteType":"All","ServiceName":"Oss"}]
