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 OSError); 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$parole') proxy_support = urllib.request.ProxyHandler({"http" : "http://ahad-haam:3128"}) # build a new opener that adds authentication and caching FTP handlers opener = urllib.request.build_opener(proxy_support, authinfo, urllib.request.CacheFTPHandler) # install it urllib.request.install_opener(opener) f = urllib.request.urlopen('http://www.python.org/') � N)�URLError� HTTPError�ContentTooShortError)�urlparse�urlsplit�urljoin�unwrap�quote�unquote� splittype� splithost� splitport� splituser� splitpasswd� splitattr� splitquery� splitvalue�splittag�to_bytes�unquote_to_bytes� urlunparse)� addinfourl� addclosehookFT�Request�OpenerDirector� BaseHandler�HTTPDefaultErrorHandler�HTTPRedirectHandler�HTTPCookieProcessor� ProxyHandler�HTTPPasswordMgr� HTTPPasswordMgrWithDefaultRealm�AbstractBasicAuthHandler�HTTPBasicAuthHandler�ProxyBasicAuthHandler�AbstractDigestAuthHandler�HTTPDigestAuthHandler�ProxyDigestAuthHandler� HTTPHandler� FileHandler� FTPHandler�CacheFTPHandler� DataHandler�UnknownHandler�HTTPErrorProcessor�urlopen�install_opener� build_opener� pathname2url� url2pathname� getproxies� urlretrieve� urlcleanup� URLopener�FancyURLopener� �cafile�capath� cadefault�contextc C s� | s | s | r� | d k r- t d � � n t sB t d � � n t j t j j d | d | �} t d | � } t | � } nF | r� t d | � } t | � } n" t d k r� t � a } n t } | j | | | � S)NzDYou can't pass both context and any of cafile, capath, and cadefaultzSSL support not availabler: r; r= ) � ValueError� _have_ssl�sslZcreate_default_contextZPurposeZ SERVER_AUTH� HTTPSHandlerr1 �_opener�open) �url�data�timeoutr: r; r< r= Z https_handler�opener� rH �3/opt/alt/python34/lib64/python3.4/urllib/request.pyr/ � s$ c C s | a d S)N)rB )rG rH rH rI r0 � s c C s� t | � \ } } t j t | | � � �E} | j � } | d k rb | rb t j j | � | f S| rz t | d � } n( t j d d � } | j } t j | � | �� | | f } d } d } d } d } d | k r� t | d � } n | r| | | | � n x] | j | � } | s!Pn | t | � 7} | j | � | d 7} | r| | | | � qqWWd QXWd QX| d k r�| | k r�t d | | f | � � n | 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�wbZdeleteFi � � r zcontent-lengthzContent-LengthNz1retrieval incomplete: got only %i out of %i bytesi ���)r � contextlib�closingr/ �info�os�path�normpathrC �tempfileZNamedTemporaryFile�name�_url_tempfiles�append�int�read�len�writer )rD �filename� reporthookrE Zurl_typerS �fp�headers�tfp�result�bs�sizerZ �blocknum�blockrH rH rI r5 � sD #c C sW x4 t D], } y t j | � Wq t k r2 Yq Xq Wt d d � =t rS d a n d S)z0Clean up temporary files from urlretrieve calls.N)rW rR �unlink�OSErrorrB )Z temp_filerH rH rI r6 � s z:\d+$c C sY | j } t | � d } | d k r: | j d d � } n t j d | d � } | j � S)z�Return request-host, as defined by RFC 2965.
