Submodules

com.vmware.content.library.item.downloadsession_client module

The Content Library Item Download Session module provides classes and classes for downloading files in a session.

class com.vmware.content.library.item.downloadsession_client.File(config)

Bases: vmware.vapi.bindings.stub.VapiInterface

The File class provides methods for accessing files within a download session.

After a download session is created against a library item, the File class can be used to retrieve all downloadable content within the library item. Since the content may not be available immediately in a downloadable form on the server side, the client will have to prepare the file and wait for the file status to become File.PrepareStatus.PREPARED.

See com.vmware.content.library.item_client.DownloadSession.

Parameters: config (vmware.vapi.bindings.stub.StubConfiguration) – Configuration to be used for creating the stub.

class EndpointType(string)

Bases: vmware.vapi.bindings.enum.Enum

The File.EndpointType class defines the types of endpoints used to download the file.

Note

This class represents an enumerated type in the interface language definition. The class contains class attributes which represent the values in the current version of the enumerated type. Newer versions of the enumerated type may contain new values. To use new values of the enumerated type in communication with a server that supports the newer version of the API, you instantiate this class. See enumerated type description page.

Parameters: string (str) – String value for the EndpointType instance.

DIRECT = EndpointType(string='DIRECT'): A direct download endpoint indicating the location of the file on storage. The caller is responsible for retrieving the file from the storage location directly.

HTTPS = EndpointType(string='HTTPS'): An https download endpoint.

class Info(name=None, size=None, bytes_transferred=None, status=None, download_endpoint=None, checksum_info=None, error_message=None)

Bases: vmware.vapi.bindings.struct.VapiStruct

The File.Info class defines the downloaded file.

Tip

The arguments are used to initialize data attributes with the same names.

Parameters

name (str) – The name of the file.
size (long or None) – The file size, in bytes. This attribute may not be available immediately. It is guaranteed to be set when the client finishes downloading the file.
bytes_transferred (long) – The number of bytes that have been transferred by the server so far for making this file prepared for download. This value may stay at zero till the client starts downloading the file.
status (File.PrepareStatus) – The preparation status (UNPREPARED, PREPARE_REQUESTED, PREPARING, PREPARED, ERROR) of the file.
download_endpoint (com.vmware.content.library.item_client.TransferEndpoint or None) – Endpoint at which the file is available for download. The value is valid only when the File.Info.status is File.PrepareStatus.PREPARED. This attribute won’t be set until the file status is File.PrepareStatus.PREPARED.
checksum_info (com.vmware.content.library.item_client.File.ChecksumInfo or None) – The checksum information of the file. When the download is complete, you can retrieve the checksum from the File.get() method to verify the checksum for the downloaded file. The checksum is always calculated for the downloaded file, but this attribute won’t be set until the download is complete.
error_message (com.vmware.vapi.std_client.LocalizableMessage or None) – Error message for a failed preparation when the prepare status is File.PrepareStatus.ERROR. This attribute won’t be set unless there was an error with the file transfer.

class PrepareStatus(string)

Bases: vmware.vapi.bindings.enum.Enum

The File.PrepareStatus class defines the state of the file in preparation for download.

Note

This class represents an enumerated type in the interface language definition. The class contains class attributes which represent the values in the current version of the enumerated type.

To use new values of the enumerated type in communication with a server that supports the newer version of the API, you instantiate this class. See enumerated type description page.

Parameters: string (str) – String value for the SourceType instance.

NONE = SourceType(string='NONE'): No source type has been requested.

PULL = SourceType(string='PULL'): The server is pulling content from a URL. The URL scheme can be http, https, file, or ds.

PUSH = SourceType(string='PUSH'): The client is uploading content using HTTP(S) PUT requests.

class ValidationError(name=None, error_message=None)

Bases: vmware.vapi.bindings.struct.VapiStruct

The File.ValidationError class defines the validation error of a file in the session.

Tip

The arguments are used to initialize data attributes with the same names.

Parameters

name (str) – The name of the file.

missing_files (set of str) – A set containing the names of the files that are required but the client hasn’t added.
invalid_files (list of File.ValidationError) – A list containing the files that have been identified as invalid and details about the error.

add(update_session_id, file_spec)

Requests file content to be changed (either created, or updated). Depending on the source type of the file, this method will either return an upload endpoint where the client can push the content, or the server will pull from the provided source endpoint. If a file with the same name already exists in this session, this method will be used to update the content of the existing file.

When importing a file directly from storage, where the source endpoint is a file or datastore URI, you will need to have the ContentLibrary.ReadStorage privilege on the library item. If the file is located in the same directory as the library storage backing folder, the server will move the file instead of copying it, thereby allowing instantaneous import of files for efficient backup and restore scenarios. In all other cases, a copy is performed rather than a move.

Parameters

update_session_id (str) – Identifier of the update session to be modified. The parameter must be an identifier for the resource type: com.vmware.content.library.item.UpdateSession.
file_spec (File.AddSpec) – Specification for the file that needs to be added or updated. This includes whether the client wants to push the content or have the server pull it.

Return type

File.Info

Returns

An File.Info class containing upload links as well as server side state tracking the transfer of the file.

Raise

com.vmware.vapi.std.errors_client.InvalidArgument if the file_spec is invalid.

Raise

com.vmware.vapi.std.errors_client.NotFound if the update session doesn’t exist.

Raise

com.vmware.vapi.std.errors_client.Unauthorized if the caller doesn’t have ContentLibrary.ReadStorage privilege on the library item of the update session and source type File.SourceType.PULL is requested for a file or datastore source endpoint (that is, not HTTP or HTTPs based endpoint).
