Backwards-compatible with :class:`http.client.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 :class:`http.client.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 :class:`http.client.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. r\ ZdeflateNr] )i- i. i/ i3 i4 � r TFc C s" t |t�r || _nt|�| _|| _|| _|| _|| _|| _d| _| | _ || _ || _ d | _ d | _ d | _| | _d| _| | _|| _|rKt |tjtf�rK|| _ | | _| | _t|d�rY|| _d| _d | _| j�dd�� � }dd� |� d�D �}d |v ryd | _| � |�| _ |r�| j s�| j |d �| _ d S d S d S ) NFr �readztransfer-encodingr` c s s � | ]}|� � V qd S r& rG )rI �encr" r" r# � <genexpr> s � z(HTTPResponse.__init__.<locals>.<genexpr>rM �chunkedT��decode_content)!� isinstancer �headers�status�version�reason�strictrf �_has_decoded_content�retries�enforce_content_length� auto_close�_decoder�_body�_fp�_original_response�_fp_bytes_read�msg� _request_urlr Z string_typesr= �_pool� _connectionrB rd � chunk_left�get�lowerrR � _init_length�length_remainingra )r! �bodyrh ri rj rk rl Zpreload_contentrf �original_response�pool� connectionrv rn ro �request_methodZ request_urlrp �tr_encrW r" r" r# r$ � sF �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)ri �REDIRECT_STATUSESrh r{ 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& )rx ry Z _put_connr r" r" r# � release_conn s zHTTPResponse.release_connc C s2 z | j | jd� W dS ttttfy Y dS w )z� Read and discard any remaining HTTP response data in the response connection.
