Backwards-compatible to httplib's HTTPResponse but the response ``body`` is loaded and decoded on-demand when the ``data`` property is accessed. 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, attempts to decode specific content-encoding's based on headers (like 'gzip' and 'deflate') will be skipped and raw data will be used instead. :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. r �deflatei- i. i/ i3 i4 � Nr Tc C s� t � | _ | r% | j j | � n | | _ | | _ | | _ | | _ | | _ d | _ | rv t | t � rv | n d | _ d | _ | | _ d | _ | | _ | | _ t | d � r� | | _ n | r� | j r� | j d | � | _ n d S)Nr �read�decode_content)r �headers�update�status�version�reason�strictr$ �_decoder� isinstance� basestring�_body�_fp�_original_response�_fp_bytes_read�_pool� _connection�hasattrr# ) r �bodyr% r' r( r) r* �preload_contentr$ �original_response�pool� connectionr r r r P s& $ zHTTPResponse.__init__c C s& | j | j k r" | j j d � Sd S)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% �get)r r r r �get_redirect_locationl s z"HTTPResponse.get_redirect_locationc C s8 | j s | j r d S| j j | j � d | _ d S)N)r2 r3 � _put_conn)r r r r � release_conny s zHTTPResponse.release_connc C s- | j r | j S| j r) | j d d � Sd S)N� cache_contentT)r. r/ r# )r r r r r � s zHTTPResponse.datac C s | j S)z� Obtain the number of bytes pulled over the wire so far.

If specified, caching is skipped because it doesn't make sense to cache partial content as the full response. :param decode_content: If True, will attempt to decode the body based on the 'content-encoding' header. :param cache_content: If True, will save the returned data such that the same result is returned despite of the state of the underlying file object. This is useful if you want the ``.data`` property to continue working after having ``.read()`` the file object.

A call will block until ``amt`` bytes have been read from the connection or until the connection is closed. :param amt: How much of the content to read. The generator will return up to much data per iteration, but may return less. This is particularly likely when using compressed data. However, the empty string will never be returned. :param decode_content: If True, will attempt to decode the body based on the 'content-encoding' header. rI r$ N)r r/ r# )r rI r$ r r r r �stream� s zHTTPResponse.streamc K s� t � } x* | j � D] \ } } | j | | � q Wt | d d � } | d | d | d | j d | j d | j d | d | | � S) a Given an :class:`httplib.HTTPResponse` instance ``r``, return a corresponding :class:`urllib3.response.HTTPResponse` object.
