Queries the list and information of text chunks.
Operation description
- For document search knowledge bases, this operation queries all chunks of a specified file. For data query or image Q&A knowledge bases, this operation retrieves information about all text chunks.
- Resource Access Management (RAM) users must first obtain API permissions for Model Studio (requires
AliyunBailianDataFullAccess, which includes the sfm:ChunkList permission), and join a workspace before invoking this operation. Alibaba Cloud accounts can invoke this operation directly without authorization. Use the latest Model Studio SDK to invoke this operation. - Before invoking this operation, make sure that your knowledge base has been created and has not been deleted (that is, the knowledge base ID
IndexIdis valid). - This operation has idempotence.

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
Actionelement 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
Resourceelement of the policy. - For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the
Resourceelement of the policy.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the
- 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.
