The CloudFiles class provides an easy way to upload, download, and manage files and folders with multiple service providers.

Syntax

class cloudstorage.CloudFiles

Remarks

The CloudFiles class provides a single interface that can be used to work with a variety of services. By supporting multiple providers with a single API code may be written once and used to support multiple services. The following providers are currently supported by this class:

• Amazon S3
• Azure Blob
• Azure File
• Backblaze B2
• Box.com
• Digital Ocean Spaces
• Dropbox
• Google Cloud Storage
• Google Drive
• Hadoop DFS
• IBM Cloud Object Storage
• Linode Object Storage
• Microsoft OneDrive
• Wasabi

The class supports simple file and folder management as well as encryption. Capabilities include uploading and downloading files, strong encryption support, creating folders, and more.

To begin, first create an account and register your application. Consult the documentation of the individual service provider for instructions on this process.

Authentication

The following providers use OAuth 2.0 for authentication:

• Box.com
• Dropbox
• Google Cloud Storage*
• Google Drive
• Microsoft OneDrive

Use the OAuth class included in the toolkit, or any other OAuth implementation to perform authentication and retrieve an authorization string. Once you've obtained an authorization string like:

Bearer ya29.AHES6ZSZEJzATdZYjeihDn5W-VrXSsxEZu5p0pclxGdKKQ

To authenticate with the remaining providers, set the account properties shown in the table below:

*Google Cloud Storage supports two authentication methods. To authenticate with OAuth 2.0 (preferred) set the authorization property and the account_project_id property. To authenticate with an access and secret key, set the account_access_key and account_secret_key properties instead.

Selecting a Provider

To specify the provider simply set service_provider. This tells the class to which service requests will be made.

Listing Files and Folders

list_directory lists files and folder the path specified by remote_path.

The directory entries are provided through the on_dir_list event and also via the dir_list property. cloudfiles.RemoteFile = ""; //Clear filemask cloudfiles.RemotePath = "MyFolder"; cloudfiles.ListDirectory(); for (int i = 0; i < cloudfiles.DirList.Count; i++) { Console.WriteLine(cloudfiles.DirList[i].FileName); Console.WriteLine(cloudfiles.DirList[i].FileSize); Console.WriteLine(cloudfiles.DirList[i].FileTime); Console.WriteLine(cloudfiles.DirList[i].IsDir); }

The remote_file property may also be used as a filemask when listing files. For instance: component.RemoteFile = "*.txt" component.ListDirectory()

Note: Since remote_file is used as a filemask be sure to clear or reset this value before calling list_directory

Downloading Files

The download method downloads a specific file.

Set remote_file to the name the file to download before calling this method. If remote_file only specifies a filename it will be downloaded from the path specified by remote_path. remote_file may also be set to an absolute path.

If local_file is set the file will be saved to the specified location. If local_file is not set the file data will be held by resource_data.

To decrypt an encrypted file set encryption_algorithm and encryption_password before calling this method. cloudfiles.RemotePath = "My Folder"; cloudfiles.RemoteFile = "MyFile.zip"; cloudfiles.LocalFile = "../MyFile.zip"; cloudfiles.Download();

Resuming Downloads

The class also supports resuming failed downloads by using the start_byte property. If the download was interrupted, set start_byte to the appropriate offset before calling this method to resume the download. cloudfiles.RemotePath = myRemoteFolder; cloudfiles.RemoteFile = myRemoteFile; cloudfiles.LocalFile = downloadFile; cloudfiles.Download(); //The transfer is interrupted and Download() above fails. Later, resume the download: //Get the size of the partially downloaded file cloudfiles.StartByte = new FileInfo(downloadFile).Length; cloudfiles.RemotePath = myRemoteFolder; cloudfiles.RemoteFile = myRemoteFile; cloudfiles.LocalFile = downloadFile; cloudfiles.Download();

Resuming Encrypted File Downloads

Resuming encrypted file downloads is only supported when local_file was set in the initial download attempt. When beginning an encrypted download if local_file is set the class will create a temporary file in TempPath to hold the encrypted data until it is complete.

If the download is interrupted DownloadTempFile will be populated with the temporary file holding the partial data. When resuming, DownloadTempFile must be populated along with start_byte to allow the remainder of the encrypted data to be downloaded. Once the encrypted data is downloaded it will be decrypted and written to local_file. cloudfiles.RemotePath = myRemoteFolder; cloudfiles.RemoteFile = myRemoteFile; cloudfiles.LocalFile = downloadFile; cloudfiles.EncryptionPassword = "password"; cloudfiles.Download(); //The transfer is interrupted and Download() above fails. Later, resume the download: //Get the size of the partially download temp file cloudfiles.StartByte = new FileInfo(cloudfiles.Config("DownloadTempFile")).Length; cloudfiles.RemotePath = myRemoteFolder; cloudfiles.RemoteFile = myRemoteFile; cloudfiles.LocalFile = downloadFile; cloudfiles.EncryptionPassword = "password"; cloudfiles.Download();

Uploading Files

The upload method is used to upload files.

remote_file should be set to either a relative or absolute path. If remote_file is not an absolute path it will be uploaded relative to remote_path.

To encrypt a file before uploading set encryption_algorithm and encryption_password.

Note: Resuming uploads is not currently supported.

Code Example: //Upload with a relative path cloudfiles.LocalFile = "C:\localfile.txt" cloudfiles.RemoteFile = "remotefile.txt" cloudfiles.Upload() //Upload with an absolute path cloudfiles.LocalFile = "C:\localfile2.txt" cloudfiles.RemoteFile = "/folder/remotefile2.txt" cloudfiles.Upload()

Additional Functionality

The CloudFiles class offers advanced functionality beyond simple uploads and downloads. For instance:

• Encrypt and decrypt files using encryption_algorithm and encryption_password.
• delete_file provides a way to delete files.
• make_directory and remove_directory support creating and deleting folders.
• rename_file allows renaming of existing files on the server.
• And more!

In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.

If the class is connected, the local_host property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

Note: local_host is not persistent. You must always set it in code, and never in the property window.

proxy_auth_scheme should be set to authNone (3) when no authentication is expected.

By default, proxy_auth_scheme is authBasic (0), and if the proxy_user and proxy_password properties are set, the class will attempt basic authentication.

If proxy_auth_scheme is set to authDigest (1), digest authentication will be attempted instead.

If proxy_auth_scheme is set to authProprietary (2), then the authorization token will not be generated by the class. Look at the configuration file for the class being used to find more information about manually setting this token.

If proxy_auth_scheme is set to authNtlm (4), NTLM authentication will be used.

For security reasons, setting this property will clear the values of proxy_user and proxy_password.

download Method

Download the specified file.

Syntax

def download() -> None: ...

Remarks

This method downloads the specified file. Set remote_file to the name the file to download before calling this method. If remote_file only specifies a filename it will be downloaded from the path specified by remote_path. remote_file may also be set to an absolute path.

If local_file is set the file will be saved to the specified location. If local_file is not set the file data will be held by resource_data.

To decrypt an encrypted file set encryption_algorithm and encryption_password before calling this method. cloudfiles.RemotePath = "My Folder"; cloudfiles.RemoteFile = "MyFile.zip"; cloudfiles.LocalFile = "../MyFile.zip"; cloudfiles.Download();

Resuming Downloads

The class also supports resuming failed downloads by using the start_byte property. If the download was interrupted, set start_byte to the appropriate offset before calling this method to resume the download. cloudfiles.RemotePath = myRemoteFolder; cloudfiles.RemoteFile = myRemoteFile; cloudfiles.LocalFile = downloadFile; cloudfiles.Download(); //The transfer is interrupted and Download() above fails. Later, resume the download: //Get the size of the partially downloaded file cloudfiles.StartByte = new FileInfo(downloadFile).Length; cloudfiles.RemotePath = myRemoteFolder; cloudfiles.RemoteFile = myRemoteFile; cloudfiles.LocalFile = downloadFile; cloudfiles.Download();

Resuming Encrypted File Downloads

Resuming encrypted file downloads is only supported when local_file was set in the initial download attempt. When beginning an encrypted download if local_file is set the class will create a temporary file in TempPath to hold the encrypted data until it is complete.

If the download is interrupted DownloadTempFile will be populated with the temporary file holding the partial data. When resuming, DownloadTempFile must be populated along with start_byte to allow the remainder of the encrypted data to be downloaded. Once the encrypted data is downloaded it will be decrypted and written to local_file. cloudfiles.RemotePath = myRemoteFolder; cloudfiles.RemoteFile = myRemoteFile; cloudfiles.LocalFile = downloadFile; cloudfiles.EncryptionPassword = "password"; cloudfiles.Download(); //The transfer is interrupted and Download() above fails. Later, resume the download: //Get the size of the partially download temp file cloudfiles.StartByte = new FileInfo(cloudfiles.Config("DownloadTempFile")).Length; cloudfiles.RemotePath = myRemoteFolder; cloudfiles.RemoteFile = myRemoteFile; cloudfiles.LocalFile = downloadFile; cloudfiles.EncryptionPassword = "password"; cloudfiles.Download();

Fired when a directory entry is received.

Syntax

class CloudFilesDirListEventParams(object):
  @property
  def file_name() -> str: ...

  @property
  def is_dir() -> bool: ...

  @property
  def file_size() -> int: ...

  @property
  def file_time() -> str: ...

# In class CloudFiles:
@property
def on_dir_list() -> Callable[[CloudFilesDirListEventParams], None]: ...
@on_dir_list.setter
def on_dir_list(event_hook: Callable[[CloudFilesDirListEventParams], None]) -> None: ...

Remarks

This event fires once for each entry returned when list_directory is called.

FileName holds the name of the file or folder.

IsDir is True for directories and False for files.

FileSize is the size of the file in bytes. For some providers this also applies directories and will return the size of all files and folders within the directory.

The table below summarizes the applicability of this value on a per-provider basis:

FileTime is the modified date of the file. By default the datetime format used is "yyyy-MM-dd'T'HH:mm:ss". To modify this format set DateFormat.

Note: Modified times are not applicable to directories for the following providers:

• cspAmazonS3 (0)
• cspDropbox (2)
• cspWasabi (7)
• cspDigitalOcean (8)
• cspGoogleStorage (9)
• cspBackblazeB2 (12)
• cspIBMStorage (13)
• cspLinode (14)

Additionally, the following providers do not return modified times at all:

• cspAzureFile (11)

on_end_transfer Event

This event fires when a document finishes transferring.

Syntax

class CloudFilesEndTransferEventParams(object):
  @property
  def direction() -> int: ...

# In class CloudFiles:
@property
def on_end_transfer() -> Callable[[CloudFilesEndTransferEventParams], None]: ...
@on_end_transfer.setter
def on_end_transfer(event_hook: Callable[[CloudFilesEndTransferEventParams], None]) -> None: ...

Remarks

The on_end_transfer event is fired when the document text finishes transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

on_error Event

Fired when information is available about errors during data delivery.

Syntax

class CloudFilesErrorEventParams(object):
  @property
  def error_code() -> int: ...

  @property
  def description() -> str: ...

# In class CloudFiles:
@property
def on_error() -> Callable[[CloudFilesErrorEventParams], None]: ...
@on_error.setter
def on_error(event_hook: Callable[[CloudFilesErrorEventParams], None]) -> None: ...

Remarks

The on_error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

on_log Event

Fired once for each log message.

Syntax

class CloudFilesLogEventParams(object):
  @property
  def log_level() -> int: ...

  @property
  def message() -> str: ...

  @property
  def log_type() -> str: ...

# In class CloudFiles:
@property
def on_log() -> Callable[[CloudFilesLogEventParams], None]: ...
@on_log.setter
def on_log(event_hook: Callable[[CloudFilesLogEventParams], None]) -> None: ...

Remarks

This event is fired once for each log message generated by the class. The verbosity is controlled by the LogLevel setting.

LogLevel indicates the level of message. Possible values are as follows:

The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

Message is the log entry.

LogType identifies the type of log entry. Possible values are as follows:

• "Info"
• "RequestHeaders"
• "ResponseHeaders"
• "RequestBody"
• "ResponseBody"
• "ProxyRequest"
• "ProxyResponse"
• "FirewallRequest"
• "FirewallResponse"

on_progress Event

Fires during an upload or download to indicate transfer progress.

Syntax

class CloudFilesProgressEventParams(object):
  @property
  def direction() -> int: ...

  @property
  def bytes_transferred() -> int: ...

  @property
  def total_bytes() -> int: ...

  @property
  def percent_done() -> int: ...

# In class CloudFiles:
@property
def on_progress() -> Callable[[CloudFilesProgressEventParams], None]: ...
@on_progress.setter
def on_progress(event_hook: Callable[[CloudFilesProgressEventParams], None]) -> None: ...

Remarks

This event fires during an upload or download to indicate the progress of the transfer of the entire request. By default, this event will fire each time PercentDone increases by one percent; the ProgressStep configuration setting can be used to alter this behavior.

Direction indicates whether the transfer is an upload (0) or a download (1).

BytesTransferred reflects the number of bytes that have been transferred so far, or 0 if the transfer is starting (however, see note below).

TotalBytes reflects the total number of bytes that are to be transferred, or -1 if the total is unknown. This amount includes the size of everything in the request like HTTP headers.

PercentDone reflects the overall progress of the transfer, or -1 if the progress cannot be calculated.

Note: By default, the class tracks transfer progress absolutely. If a transfer is interrupted and later resumed, the values reported by this event upon and after resumption will account for the data that was transferred before the interruption.

For example, if 10MB of data was successfully transferred before the interruption, then this event will fire with a BytesTransferred value of 10485760 (10MB) when the transfer is first resumed, and then continue to fire with successively greater values as usual.

This behavior can be changed by disabling the ProgressAbsolute configuration setting, in which case the class will treat resumed transfers as "new" transfers. In this case, the BytesTransferred parameter will always be 0 the first time this event fires, regardless of whether the transfer is new or being resumed.

on_ssl_server_authentication Event

Fired after the server presents its certificate to the client.

Syntax

class CloudFilesSSLServerAuthenticationEventParams(object):
  @property
  def cert_encoded() -> bytes: ...

  @property
  def cert_subject() -> str: ...

  @property
  def cert_issuer() -> str: ...

  @property
  def status() -> str: ...

  @property
  def accept() -> bool: ...
  @accept.setter
  def accept(value) -> None: ...

# In class CloudFiles:
@property
def on_ssl_server_authentication() -> Callable[[CloudFilesSSLServerAuthenticationEventParams], None]: ...
@on_ssl_server_authentication.setter
def on_ssl_server_authentication(event_hook: Callable[[CloudFilesSSLServerAuthenticationEventParams], None]) -> None: ...

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

on_ssl_status Event

Fired when secure connection progress messages are available.

Syntax

class CloudFilesSSLStatusEventParams(object):
  @property
  def message() -> str: ...

# In class CloudFiles:
@property
def on_ssl_status() -> Callable[[CloudFilesSSLStatusEventParams], None]: ...
@on_ssl_status.setter
def on_ssl_status(event_hook: Callable[[CloudFilesSSLStatusEventParams], None]) -> None: ...

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

on_start_transfer Event

This event fires when a document starts transferring (after the headers).

Syntax

class CloudFilesStartTransferEventParams(object):
  @property
  def direction() -> int: ...

# In class CloudFiles:
@property
def on_start_transfer() -> Callable[[CloudFilesStartTransferEventParams], None]: ...
@on_start_transfer.setter
def on_start_transfer(event_hook: Callable[[CloudFilesStartTransferEventParams], None]) -> None: ...

Remarks

The on_start_transfer event is fired when the document text starts transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

on_transfer Event

Fired while a document transfers (delivers document).

Syntax

class CloudFilesTransferEventParams(object):
  @property
  def direction() -> int: ...

  @property
  def bytes_transferred() -> int: ...

  @property
  def percent_done() -> int: ...

  @property
  def text() -> bytes: ...

# In class CloudFiles:
@property
def on_transfer() -> Callable[[CloudFilesTransferEventParams], None]: ...
@on_transfer.setter
def on_transfer(event_hook: Callable[[CloudFilesTransferEventParams], None]) -> None: ...

Remarks

The Text parameter contains the portion of the document text being received. It is empty if data are being posted to the server.

The BytesTransferred parameter contains the number of bytes transferred in this Direction since the beginning of the document text (excluding HTTP response headers).

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.
