If a ``path`` parameter is a directory, this function will parse the ``Content-Disposition`` header on the response to determine the name of the file as reported by the server, and return a file path in the specified directory. If ``path`` is empty or None, this function will return a path relative to the process' current working directory. If path is a full file path, return it. :param response: A Response object from requests :type response: requests.models.Response :param str path: Directory or file path. :returns: full file path to download as :rtype: str :raises: :class:`requests_toolbelt.exceptions.StreamingError` s content-dispositiont s' No filename given to stream response to( R R t isdirR t headerst gett exct StreamingErrort join( t responseR t path_is_dirt filepatht response_filename( ( sJ /usr/lib/python2.7/site-packages/requests_toolbelt/downloadutils/stream.pyt get_download_file_path s c C s� t } d } d } | rW t t | d d � t j � rW t } | } t | d d � } nF t | | � } t j j | � r� t j d | � � n t | d � } x' | j d | � D] } | j | � q� W| s� | j � n | S( s7 Stream a response body to the specified file. Either use the ``path`` provided or use the name provided in the ``Content-Disposition`` header. .. warning:: If you pass this function an open file-like object as the ``path`` parameter, the function will not close that file for you. .. warning:: This function will not automatically close the response object passed in as the ``response`` parameter. If a ``path`` parameter is a directory, this function will parse the ``Content-Disposition`` header on the response to determine the name of the file as reported by the server, and return a file path in the specified directory. If no ``path`` parameter is supplied, this function will default to the process' current working directory. .. code-block:: python import requests from requests_toolbelt import exceptions from requests_toolbelt.downloadutils import stream r = requests.get(url, stream=True) try: filename = stream.stream_response_to_file(r) except exceptions.StreamingError as e: # The toolbelt could not find the filename in the # Content-Disposition print(e.message) You can also specify the filename as a string. This will be passed to the built-in :func:`open` and we will read the content into the file. .. code-block:: python import requests from requests_toolbelt.downloadutils import stream r = requests.get(url, stream=True) filename = stream.stream_response_to_file(r, path='myfile') If the calculated download file path already exists, this function will raise a StreamingError. Instead, if you want to manage the file object yourself, you need to provide either a :class:`io.BytesIO` object or a file opened with the `'b'` flag. See the two examples below for more details. .. code-block:: python import requests from requests_toolbelt.downloadutils import stream with open('myfile', 'wb') as fd: r = requests.get(url, stream=True) filename = stream.stream_response_to_file(r, path=fd) print('{0} saved to {1}'.format(url, filename)) .. code-block:: python import io import requests from requests_toolbelt.downloadutils import stream b = io.BytesIO() r = requests.get(url, stream=True) filename = stream.stream_response_to_file(r, path=b) assert filename is None :param response: A Response object from requests :type response: requests.models.Response :param path: *(optional)*, Either a string with the path to the location to save the response content, or a file-like object expecting bytes. :type path: :class:`str`, or object with a :meth:`write` :param int chunksize: (optional), Size of chunk to attempt to stream (default 512B). :returns: The name of the file, if one can be determined, else None :rtype: str :raises: :class:`requests_toolbelt.exceptions.StreamingError` t writet names File already exists: %st wbt chunk_sizeN( t FalseR t isinstancet getattrt collectionst Callablet TrueR R R t existsR R t opent iter_contentR t close( R R t chunksizet pre_openedt fdR t chunk( ( sJ /usr/lib/python2.7/site-packages/requests_toolbelt/downloadutils/stream.pyt stream_response_to_fileG s W$ ( t __doc__R! t os.pathR t reR R R t _QUOTED_STRING_REt compileR t _DEFAULT_CHUNKSIZER R R R, ( ( ( sJ /usr/lib/python2.7/site-packages/requests_toolbelt/downloadutils/stream.pyt <module> s +
