Backwards-compatible to httplib's HTTPResponse but the response ``body`` is loaded and decoded on-demand when the ``data`` property is accessed. This class is also compatible with the Python standard library's :mod:`io` module, and can hence be treated as a readable object in the context of that framework. Extra parameters for behaviour not present in httplib.HTTPResponse: :param preload_content: If True, the response's body will be preloaded during construction. :param decode_content: If True, will attempt to decode the body based on the 'content-encoding' header. :param original_response: When this HTTPResponse wrapper is generated from an httplib.HTTPResponse object, it's convenient to include the original for debug purposes. It's otherwise unused. :param retries: The retries contains the last :class:`~urllib3.util.retry.Retry` that was used during the request. :param enforce_content_length: Enforce content length checking. Body returned by server must match value of Content-Length header, if present. Otherwise, raise error. rR �deflateNrS )i- i. i/ i3 i4 � r TFc C s t |t�r|| _n t|�| _|| _|| _|| _|| _|| _| | _|| _ || _ d | _ d | _ d | _ | | _d| _| | _|| _|r�t |ttf�r�|| _ | | _| | _t|d�r�|| _ d| _d | _| j�dd��� }dd� |�d�D �}d |v r�d | _| � |�| _ |�r| j �s| j |d �| _ d S ) Nr �readFztransfer-encodingrW c s s | ]}|� � V qd S r# )rF )rG �encr r r! � <genexpr>� r z(HTTPResponse.__init__.<locals>.<genexpr>rJ �chunkedT��decode_content) � isinstancer �headers�status�version�reason�strictr] �retries�enforce_content_length� auto_close�_decoder�_body�_fp�_original_response�_fp_bytes_read�msg� _request_url� basestringr; �_pool� _connectionrA r[ � chunk_left�get�lowerrK � _init_length�length_remainingrX )r �bodyr_ r` ra rb rc �preload_contentr] �original_response�pool� connectionrl rd re �request_method� request_urlrf �tr_enc� encodingsr r r! r" � sB zHTTPResponse.__init__c C s | j | jv r| j�d�S dS )a Should we redirect and where to? :returns: Truthy redirect location string if we got a redirect status code and valid location. ``None`` if redirect status and no location. ``False`` if not a redirect status code. �locationF)r` �REDIRECT_STATUSESr_ rr r r r r! �get_redirect_location s z"HTTPResponse.get_redirect_locationc C s( | j r | jsd S | j �| j� d | _d S r# )ro rp � _put_connr r r r! � release_conn s zHTTPResponse.release_connc C s, z | � � W n ttttfy& Y n0 dS )z� Read and discard any remaining HTTP response data in the response connection.
