EnumerateChildren (containers)

GET /wopi/containers/(container_id)/children

The EnumerateChildren operation enumerates all the immediate children of a given container. Note that paging is deliberately not supported by this operation. Responses are expected to include all immediate children of the container.

Parameters

• container_id (string) – A string that specifies a container ID of a container managed by host. This string must be URL safe.

Query Parameters

• access_token (string) – An access token that the host will use to determine whether the request is authorized.

Request Headers

• X-WOPI-FileExtensionFilterList –

  A string value that the host must use to filter the returned child files. This header must be a list of comma-separated file extensions with a leading dot (.). There must be no whitespace and no trailing comma in the string. Wildcard characters are not permitted.

  If this header is included, the host must only return child files whose file extensions match the filter list, based on a case-insensitive match. For example, if this header is set to the value .doc,.docx, the host should include only files with the doc or docx file extension.

  This header value only affects the child files that are returned; it does not have any effect on child containers.

Status Codes

• 200 OK – Success

• 401 Unauthorized – Invalid access token

• 404 Not Found – Resource not found/user unauthorized

• 500 Internal Server Error – Server error

• 501 Not Implemented – Operation not supported

Response

The response to a EnumerateChildren call is JSON.

All optional values default to the following values based on their type:

Required response properties

The following properties must be present in all EnumerateChildren responses:

• ChildContainers - An array of JSON-formatted objects containing the following properties:

  • Name - The name of the container without a path. This value should match the Name property in a CheckContainerInfo response. Required.

  • Url - A URI to the container, including a valid access token. Required.

    Caution

    This property includes an access token, and thus has important security implications. See Preventing ‘token trading’ for more details.

  If there are no child containers, this property should be an empty array.

• ChildFiles - An array of JSON-formatted objects containing the following properties:

  • Name - Should match the BaseFileName property in CheckFileInfo. Required.

  • Size - Should match the Size property in CheckFileInfo. Required.

  • Url - A URI to the file, including a valid access token. Required.

  Caution

  This property includes an access token, and thus has important security implications. See Preventing ‘token trading’ for more details.

  • Version - Should match the Version property in CheckFileInfo. Required.

  • LastModifiedTime - Should match the LastModifiedTime property in CheckFileInfo. Optional.

  If there are no child files, this property should be an empty array.
