An extensible library for opening URLs using a variety of protocols The simplest way to use this module is to call the urlopen function, which accepts a string containing a URL or a Request object (described below). It opens the URL and returns the results as file-like object; the returned object has some extra methods described below. The OpenerDirector manages a collection of Handler objects that do all the actual work. Each Handler implements a particular protocol or option. The OpenerDirector is a composite object that invokes the Handlers needed to open the requested URL. For example, the HTTPHandler performs HTTP GET and POST requests and deals with non-error returns. The HTTPRedirectHandler automatically deals with HTTP 301, 302, 303 and 307 redirect errors, and the HTTPDigestAuthHandler deals with digest authentication. urlopen(url, data=None) -- Basic usage is the same as original urllib. pass the url and optionally data to post to an HTTP URL, and get a file-like object back. One difference is that you can also pass a Request instance instead of URL. Raises a URLError (subclass of IOError); for HTTP errors, raises an HTTPError, which can also be treated as a valid response. build_opener -- Function that creates a new OpenerDirector instance. Will install the default handlers. Accepts one or more Handlers as arguments, either instances or Handler classes that it will instantiate. If one of the argument is a subclass of the default handler, the argument will be installed instead of the default. install_opener -- Installs a new opener as the default opener. objects of interest: OpenerDirector -- Sets up the User Agent as the Python-urllib client and manages the Handler classes, while dealing with requests and responses. Request -- An object that encapsulates the state of a request. The state can be as simple as the URL. It can also include extra HTTP headers, e.g. a User-Agent. BaseHandler -- internals: BaseHandler and parent _call_chain conventions Example usage: import urllib.request # set up authentication info authinfo = urllib.request.HTTPBasicAuthHandler() authinfo.add_password(realm='PDQ Application', uri='https://mahler:8092/site-updates.py', user='klem', passwd='geheim$parole') proxy_support = urllib.request.ProxyHandler({"http" : "http://ahad-haam:3128"}) # build a new opener that adds authentication and caching FTP handlers opener = urllib.request.build_opener(proxy_support, authinfo, urllib.request.CacheFTPHandler) # install it urllib.request.install_opener(opener) f = urllib.request.urlopen('http://www.python.org/') � )�absolute_import�division�print_function�unicode_literals)�bytes�dict�filter�input�int�map�open�str)�PY2�PY3�raise_with_tracebackN)�email)�client� )�URLError� HTTPError�ContentTooShortError)�urlparse�urlsplit�urljoin�unwrap�quote�unquote� splittype� splithost� splitport� splituser� splitpasswd� splitattr� splitquery� splitvalue�splittag�to_bytes� urlunparse)� addinfourl� addclosehook)r )�Iterable)� SSLContextFT�Request�OpenerDirector� BaseHandler�HTTPDefaultErrorHandler�HTTPRedirectHandler�HTTPCookieProcessor� ProxyHandler�HTTPPasswordMgr� HTTPPasswordMgrWithDefaultRealm�AbstractBasicAuthHandler�HTTPBasicAuthHandler�ProxyBasicAuthHandler�AbstractDigestAuthHandler�HTTPDigestAuthHandler�ProxyDigestAuthHandler� HTTPHandler� FileHandler� FTPHandler�CacheFTPHandler�UnknownHandler�HTTPErrorProcessor�urlopen�install_opener� build_opener� pathname2url� url2pathname� getproxies� urlretrieve� urlcleanup� URLopener�FancyURLopener� c K s� d|kr|d }|d= nd}d|kr4|d }|d= nd }d|krP|d }|d= nd }|s`|s`|r�t sltd��tjtj�}| jtjO _tj|_|s�|r�|j ||� n|j � t |dd�}t |�} nt d kr�t � a } nt } | j| ||�S )N� cadefaultF�capath�cafilezSSL support not availableT)�context�check_hostname)� _have_ssl� ValueError�sslr+ �PROTOCOL_SSLv23�options� OP_NO_SSLv2� CERT_REQUIRED� verify_mode�load_verify_locations�set_default_verify_paths� HTTPSHandlerrC �_openerr ) �url�data�timeoutZ _3to2kwargsrL rM rN rO � https_handler�opener� rb �F/root/tmp/pip-build-3x0y2zol/future/future/backports/urllib/request.pyrA � s6 c C s | a d S )N)r\ )ra rb rb rc rB � s c C s4 t | �\}}tjt| |����}|j� }|dkrD| rDtjj|�|fS |rTt|d�}n t j dd�}|j }t j |� |�� ||f} d } d} d} d} d |kr�t|d �} |r�|| | | � xB|j| �}|s�P | t|�7 } |j|� | d7 } |r�|| | | � q�W W d Q R X W d Q R X | dk�r0| | k �r0td | | f | ��| S )aW Retrieve a URL into a temporary location on disk. Requires a URL argument. If a filename is passed, it is used as the temporary file location. The reporthook argument should be a callable that accepts a block number, a read size, and the total file size of the URL target. The data argument should be valid URL encoded data. If a filename is passed and the URL points to a local resource, the result is a copy from local file to new file. Returns a tuple containing the path to the newly created data file as well as the resulting HTTPMessage object. �file�wbF)�deletei � r r zcontent-lengthzContent-LengthNz1retrieval incomplete: got only %i out of %i bytesi ���)r � contextlib�closingrA �info�os�path�normpathr �tempfile�NamedTemporaryFile�name�_url_tempfiles�appendr �read�len�writer )r] �filename� reporthookr^ �url_typerm �fp�headers�tfp�result�bs�sizert �blocknum�blockrb rb rc rG � sD $c C sH x0t D ](} ytj| � W q tk r, Y qX qW t d d �= trDd ad S )N)rr rl �unlink�EnvironmentErrorr\ )� temp_filerb rb rc rH � s z:\d+$c C s< | j }t|�d }|dkr&| jdd�}tjd|d�}|j� S )z�Return request-host, as defined by RFC 2965.
