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.

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. r� Nr )r� r� )r� �supports_chunked_readsr� r r� rp r� r� )r' r� r� r! r( r( r) r� s zHTTPResponse.streamc C s dS )NTr( r, r( r( r) �readable* s zHTTPResponse.readablec C s< | j s| jr| j�� | jr&| j�� | js8tj�| � d S r# )r r� r� r� r� ru �IOBaser, r( r( r) r� - s zHTTPResponse.closec C sT | j stjj�| �S | jd u r"dS t| jd�r8| j�� S t| jd�rL| jjS dS d S )NTr� r )r� ru r r �__get__r� rL r� r, r( r( r) r 7 s zHTTPResponse.closedc C s6 | j d u rtd��n t| j d�r*| j �� S td��d S )Nz-HTTPResponse has no file to get a fileno from�filenozOThe file-like object this HTTPResponse is wrapped around has no file descriptor)r� r� rL r r, r( r( r) r D s �zHTTPResponse.filenoc C s2 | j d ur.t| j d�r.t| j dd�s.| j �� S d S )Nr- r F)r� rL r r- r, r( r( r) r- O s � � �zHTTPResponse.flushc C s t | jd�S )a Checks if the underlying file-like object looks like a :class:`http.client.HTTPResponse` object.
