.. py:class:: FTPHook(ftp_conn_id = default_conn_name)

   Bases: :py:obj:`airflow.hooks.base.BaseHook`

   Interact with FTP.

   Errors that may occur throughout but should be handled downstream.
   You can specify mode for data transfers in the extra field of your
   connection as ``{"passive": "true"}``.

   :param ftp_conn_id: The :ref:`ftp connection id <howto/connection:ftp>`
       reference.

   .. py:method:: __enter__(self)


   .. py:method:: __exit__(self, exc_type, exc_val, exc_tb)


   .. py:method:: get_conn(self)

      Returns a FTP connection object


   .. py:method:: close_conn(self)

      Closes the connection. An error will occur if the
      connection wasn't ever opened.


   .. py:method:: describe_directory(self, path)

      Returns a dictionary of {filename: {attributes}} for all files
      on the remote system (where the MLSD command is supported).

      :param path: full path to the remote directory


   .. py:method:: list_directory(self, path)

      Returns a list of files on the remote system.

      :param path: full path to the remote directory to list


   .. py:method:: create_directory(self, path)

      Creates a directory on the remote system.

      :param path: full path to the remote directory to create


   .. py:method:: delete_directory(self, path)

      Deletes a directory on the remote system.

      :param path: full path to the remote directory to delete


   .. py:method:: retrieve_file(self, remote_full_path, local_full_path_or_buffer, callback=None)

      Transfers the remote file to a local location.

      If local_full_path_or_buffer is a string path, the file will be put
      at that location; if it is a file-like buffer, the file will
      be written to the buffer but not closed.

      :param remote_full_path: full path to the remote file
      :param local_full_path_or_buffer: full path to the local file or a
          file-like buffer
      :param callback: callback which is called each time a block of data
          is read. if you do not use a callback, these blocks will be written
          to the file or buffer passed in. if you do pass in a callback, note
          that writing to a file or buffer will need to be handled inside the
          callback.

              print_progress(percent_progress)


          hook.retrieve_file(remote_path, None, callback=write_to_file_with_progress)

          # without a custom callback data is written to the local_path
          hook.retrieve_file(remote_path, local_path)


   .. py:method:: store_file(self, remote_full_path, local_full_path_or_buffer)

      Transfers a local file to the remote location.

      If local_full_path_or_buffer is a string path, the file will be read
      from that location; if it is a file-like buffer, the file will
      be read from the buffer but not closed.

      :param remote_full_path: full path to the remote file
      :param local_full_path_or_buffer: full path to the local file or a
          file-like buffer


   .. py:method:: delete_file(self, path)

      Removes a file on the FTP Server.

      :param path: full path to the remote file


   .. py:method:: rename(self, from_name, to_name)

      Rename a file.

      :param from_name: rename file from name
      :param to_name: rename file to name


   .. py:method:: get_mod_time(self, path)

      Returns a datetime object representing the last time the file was modified

      :param path: remote file path


   .. py:method:: get_size(self, path)

      Returns the size of a file (in bytes)

      :param path: remote file path


   .. py:method:: test_connection(self)

      Test the FTP connection by calling path with directory


.. py:class:: FTPSHook(ftp_conn_id = default_conn_name)

   Bases: :py:obj:`FTPHook`

   Interact with FTPS.

   .. py:method:: get_conn(self)

      Returns a FTPS connection object.
