This parameter is ignored in Python 3. :param timeout: Socket timeout in seconds for each individual connection. This can be a float or integer, which sets the timeout for the HTTP request, or an instance of :class:`urllib3.util.Timeout` which gives you more fine-grained control over request timeouts. After the constructor has been parsed, this is always a `urllib3.util.Timeout` object. :param maxsize: Number of connections to save that can be reused. More than 1 is useful in multithreaded situations. If ``block`` is set to false, more connections will be created but they will not be saved once they've been used. :param block: If set to True, no more than ``maxsize`` connections will be used at a time. When no free connections are available, the call will block until a connection has been released. This is a useful side effect for particular multithreaded situations where one does not want to use more than maxsize connections per host to prevent flooding. :param headers: Headers to include with all requests, unless other headers are given explicitly. :param _proxy: Parsed proxy URL, should not be used directly, instead, see :class:`urllib3.connectionpool.ProxyManager`" :param _proxy_headers: A dictionary with proxy headers, should not be used directly, instead, see :class:`urllib3.connectionpool.ProxyManager`" �httpNFr c K s� t j | | | � t j | | � | | _ t | t � sM t j | � } n | | _ | j | � | _ | | _ | | _ | p� i | _ x$ t | � D] } | j j d � q� Wd | _ d | _ t j d k r� | j d d � n | | _ d S)Nr � � �source_address)r3 r4 )r! r( r �strict� isinstancer � from_floatr r0 �pool�block�proxy� proxy_headers�xrange�put�num_connections� num_requests�sys� version_info�pop�conn_kw) r% r# r$ r6 r �maxsizer: �headers�_proxy�_proxy_headersrD �_r& r& r' r( � s" zHTTPConnectionPool.__init__c C s� | j d 7_ t j d | j | j f � | j d | j d | j d | j j d | j | j � } | j d k r� d | _ n | S) z9 Return a fresh :class:`HTTPConnection`. r z%Starting new HTTP connection (%d): %sr# r$ r r6 Nr ) r? �log�infor# � ConnectionClsr$ r �connect_timeoutr6 rD r; � tcp_nodelay)r% �connr& r& r' � _new_conn� s z HTTPConnectionPool._new_connc C s� d } y" | j j d | j d | � } WnM t k rK t | d � � Yn- t k rw | j rs t | d � � n Yn X| r� t | � r� t j d | j � | j � n | p� | j � S)a� Get a connection.

This is the lowest level call for making a request, so you'll need to specify all the raw details. .. note:: More commonly, it's appropriate to use a convenience method provided by :class:`.RequestMethods`, such as :meth:`request`. .. note:: `release_conn` will only behave as expected if `preload_content=False` because we want to make `preload_content=False` the default behaviour someday soon without breaking backwards compatibility. :param method: HTTP request method (such as GET, POST, PUT, etc.) :param body: Data to send in the request body (useful for creating POST requests, see HTTPConnectionPool.post_url for more convenience). :param headers: Dictionary of custom headers to send, such as User-Agent, If-None-Match, etc. If None, pool headers are used. If provided, these headers completely replace any pool-specific headers. :param retries: Number of retries to allow before raising a MaxRetryError exception. If `False`, then retries are disabled and any exception is raised immediately. :param redirect: If True, automatically handle redirects (status codes 301, 302, 303, 307, 308). Each redirect counts as a retry. Disabling retries will disable redirect, too. :param assert_same_host: If ``True``, will make sure that the host of the pool requests is consistent else will raise HostChangedError. When False, you can use the pool on an HTTP proxy and request foreign hosts. :param timeout: If specified, overrides the default timeout for this one request. It may be a float (in seconds) or an instance of :class:`urllib3.util.Timeout`. :param pool_timeout: If set and the pool is set to block=True, then this method will block for ``pool_timeout`` seconds and raise EmptyPoolError if no connection is available within the time period. :param release_conn: If False, then the urlopen call will not release the connection back into the pool once a response is received (but will release if you read the entire contents of the response such as when `preload_content=True`). This is useful if you're not preloading the response's content immediately. You will need to call ``r.release_conn()`` on the response ``r`` to return the connection back into the pool. If None, it takes the value of ``response_kw.get('preload_content', True)``. :param \**response_kw: Additional parameters are passed to :meth:`urllib3.response.HTTPResponse.from_httplib` Nr F�preload_contentTr r2 r �bodyrF r9 � connectionz"No pool connections are available.zCannot connect to proxy.zConnection failed.zARetrying (%d attempts remain) after connection broken by '%r': %s� pool_timeout� release_conni/ �GETzRedirecting %s -> %s)!rF r rQ r{ r r/ �copy�updater< rT rw r � from_httplibr r r r r r r ri rS r7 r; r r rV rJ rU �urlopen�get_redirect_locationrn rK )r% rp rq r~ rF �retries�redirect�assert_same_hostr r� r� � response_kwrO �errrt � response_conn�responseru �redirect_locationr& r& r' r� � sx H zHTTPConnectionPool.urlopen)r* r, r- r. r/ r rL r rb r( rP rT rV rY rW rw rS r{ r� r& r& r& r' r1 U s 3 !

When Python is compiled with the :mod:`ssl` module, then :class:`.VerifiedHTTPSConnection` is used, which *can* verify certificates, instead of :class:`.HTTPSConnection`. :class:`.VerifiedHTTPSConnection` uses one of ``assert_fingerprint``, ``assert_hostname`` and ``host`` in this order to verify connections. If ``assert_hostname`` is False, no verification is done. The ``key_file``, ``cert_file``, ``cert_reqs``, ``ca_certs`` and ``ssl_version`` are only used if :mod:`ssl` is available and are fed into :meth:`urllib3.util.ssl_wrap_socket` to upgrade the connection socket into an SSL socket. �httpsNFr c K s� t j d k r" | j d d � n t j | | | | | | | | | | | � | | _ | | _ | | _ | | _ | | _ | | _ | | _ | | _ d S)Nr3 r4 r5 )r3 r4 ) rA rB rC r1 r( �key_file� cert_file� cert_reqs�ca_certs� ssl_version�assert_hostname�assert_fingerprintrD )r% r# r$ r6 r rE r: rF rG rH r� r� r� r� r� r� r� rD r& r& r' r( W s z HTTPSConnectionPool.__init__c C s� t | t � rj | j d | j d | j d | j d | j d | j d | j � | j | _ | j | _ n | j d k r� y | j } Wn t k r� | j } Yn X| | j | j | j � | j � n | S)z� Prepare the ``connection`` for :meth:`urllib3.util.ssl_wrap_socket` and establish the tunnel if proxy is used. r� r� r� r� r� r� N)r7 r �set_certr� r� r� r� r� r� r� rD r; � set_tunnelrR � _set_tunnelr# r$ r< �connect)r% rO r� r& r& r' � _prepare_connn s" z!HTTPSConnectionPool._prepare_connc C s | j d 7_ t j d | j | j f � | j sE | j t k rT t d � � n | j } | j } | j d k r� | j j } | j j } n i } t j s� | j | d <n | j | j � | j d | d | d | j j | � } | j d k rd | _ n | j | � S) zB Return a fresh :class:`httplib.HTTPSConnection`. r z&Starting new HTTPS connection (%d): %szCCan't connect to HTTPS URL because the SSL module is not available.Nr6 r# r$ r r )r? rJ rK r# rL r r r$ r; r �PY3r6 r� rD r rM rN r� )r% � actual_host� actual_port� extra_paramsrO r& r& r' rP � s( z HTTPSConnectionPool._new_conn) r* r, r- r. r/ r rL r( r� rP r& r& r& r' r� B s r� c K sK t | � \ } } } | d k r4 t | d | | �St | d | | �Sd S)a� Given a url, return an :class:`.ConnectionPool` instance of its host.

Port is optional. :param \**kw: Passes additional parameters to the constructor of the appropriate :class:`.ConnectionPool`.
