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)� 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��t�tj�}| jtjO _tj|_|s�|r�|� ||� n|� � t |dd�}t |�} nt d kr�t � a } nt } | �| ||�S )N� cadefaultF�capath�cafilezSSL support not availableT)�context�check_hostname)� _have_ssl� ValueError�sslr* ZPROTOCOL_SSLv23�optionsZ OP_NO_SSLv2Z CERT_REQUIREDZ verify_modeZload_verify_locationsZset_default_verify_paths� HTTPSHandlerrB �_openerr ) �url�data�timeoutZ _3to2kwargsrK rL rM rN Z https_handler�opener� rZ �P/opt/alt/python37/lib/python3.7/site-packages/future/backports/urllib/request.pyr@ � s6 c C s | a d S )N)rU )rY rZ rZ r[ rA � s c C s2 t | �\}}t�t| |����}|�� }|dkrB|sBtj�|�|fS |rRt|d�}n t j dd�}|j }t � |� |�� ||f} d} d} d} d} d|kr�t|d �} |r�|| | | � xB|�| �}|s�P | t|�7 } |�|� | d 7 } |r�|| | | � q�W W d Q R X W d Q R X | dk�r.| | k �r.td | | 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 zcontent-lengthzContent-Lengthr Nz1retrieval incomplete: got only %i out of %i bytes)r � contextlib�closingr@ �info�os�path�normpathr �tempfileZNamedTemporaryFile�name�_url_tempfiles�appendr �read�len�writer )rV �filename� reporthookrW Zurl_typerd �fp�headers�tfp�result�bs�sizerj �blocknum�blockrZ rZ r[ rF � sD $c C sH x0t D ](} yt�| � W q tk r, Y qX qW t d d �= trDd ad S )N)rh rc �unlink�EnvironmentErrorrU )Z temp_filerZ rZ r[ rG � s z:\d+$c C s< | j }t|�d }|dkr&| �dd�}t�d|d�}|�� S )z�Return request-host, as defined by RFC 2965.

According to RFC 3986, having an authority component means the URL must have two slashes after the scheme: >>> _parse_proxy('file:/ftp.example.com/') Traceback (most recent call last): ValueError: proxy URL with no authority: 'file:/ftp.example.com/' The first three items of the returned tuple may be None. Examples of authority parsing: >>> _parse_proxy('proxy.example.com') (None, None, None, 'proxy.example.com') >>> _parse_proxy('proxy.example.com:3128') (None, None, None, 'proxy.example.com:3128') The authority component may optionally include userinfo (assumed to be username:password): >>> _parse_proxy('joe:password@proxy.example.com') (None, 'joe', 'password', 'proxy.example.com') >>> _parse_proxy('joe:password@proxy.example.com:3128') (None, 'joe', 'password', 'proxy.example.com:3128') Same examples, but with URLs instead: >>> _parse_proxy('http://proxy.example.com/') ('http', None, None, 'proxy.example.com') >>> _parse_proxy('http://proxy.example.com:3128/') ('http', None, None, 'proxy.example.com:3128') >>> _parse_proxy('http://joe:password@proxy.example.com/') ('http', 'joe', 'password', 'proxy.example.com') >>> _parse_proxy('http://joe:password@proxy.example.com:3128') ('http', 'joe', 'password', 'proxy.example.com:3128') Everything after the authority is ignored: >>> _parse_proxy('ftp://joe:password@proxy.example.com/rubbish:3128') ('ftp', 'joe', 'password', 'proxy.example.com') Test for no trailing '/' case: >>> _parse_proxy('http://joe:password@proxy.example.com') ('http', 'joe', 'password', 'proxy.example.com') r Nz//z proxy URL with no authority: %rr� r_ )r r� rQ r� r r! ) �proxyr Zr_scheme� authority�endZuserinfo�hostport�user�passwordrZ rZ r[ � _parse_proxy� s 2 r c @ s" e Zd ZdZddd�Zdd� ZdS )r1 �d Nc C s^ |d krt � }t|d�s td��|| _x2|�� D ]&\}}t| d| ||| jfdd�� q0W d S )N�keyszproxies must be a mappingz%s_openc S s || ||�S )NrZ )�rr r� r� rZ rZ r[ �<lambda>) s z'ProxyHandler.__init__.<locals>.<lambda>)rE r� �AssertionError�proxiesr� �setattrr� )r� r# r� rV rZ rZ r[ r� " s zProxyHandler.__init__c C s� |j }t|�\}}}}|d kr"|}|jr6t|j�r6d S |rv|rvdt|�t|�f } t�| �� ��d�} |� dd| � t|�}|� ||� ||ks�|dkr�d S | j j ||j d�S d S )Nz%s:%s�asciizProxy-authorizationzBasic r� )rX )r� r r� � proxy_bypassr �base64� b64encode�encoder� r� r� r� r rX ) r� r� r r� Z orig_typeZ proxy_typer r r Z user_passZcredsrZ rZ r[ r� , s zProxyHandler.proxy_open)N)r� r� r� r� r� r� rZ rZ rZ r[ r1 s c @ s6 e Zd Zdd� Zdd� Zdd� Zd dd �Zd d � Zd S )r2 c C s i | _ d S )N)�passwd)r� rZ rZ r[ r� J s zHTTPPasswordMgr.__init__c s` t |t�r|g}|�jkr$i �j|< x6dD ].� t� �fdd�|D ��}||f�j| |< q*W d S )N)TFc s g | ]}�� |� ��qS rZ )� reduce_uri)r �u)� default_portr� rZ r[ � <listcomp>U s z0HTTPPasswordMgr.add_password.<locals>.<listcomp>)r� r r* �tuple)r� �realmr r r* Z reduced_urirZ )r- r� r[ � add_passwordM s z HTTPPasswordMgr.add_passwordc C s` | j �|i �}xLdD ]D}| �||�}x2|�� D ]&\}}x |D ]}| �||�r<|S q<W q.W qW dS )N)TF)NN)r* r� r+ r� � is_suburi) r� r0 �authuriZdomainsr- Zreduced_authuriZurisZauthinfor rZ rZ r[ �find_user_passwordX s z"HTTPPasswordMgr.find_user_passwordTc C s� t |�}|d r.|d }|d }|d p*d}n d}|}d}t|�\}}|r~|dkr~|dk r~ddd��|�} | dk r~d || f }||fS ) z@Accept authority or URI and extract only the authority and path.r r r� r N�P i� )r� r� z%s:%d)r r r� ) r� r r- �partsr r rd r� �portZdportrZ rZ r[ r+ b s zHTTPPasswordMgr.reduce_uric C sR ||kr dS |d |d kr dS t �|d |d f�}t|�t|d �krNdS dS )zcCheck if test is below base in a URI tree Both args must be URIs in reduced form.
