Most of the classes and functions provided by this module are used by the wrappers, but they are useful on their own, too, especially if the response and request objects are not used. This covers some of the more HTTP centric features of WSGI, some other utilities such as cookie handling are documented in the `werkzeug.utils` module. :copyright: (c) 2014 by the Werkzeug Team, see AUTHORS for more details. :license: BSD, see LICENSE for more details. i����N( t timet gmtime( t parsedate_tz( t parse_http_list( t datetimet timedelta( t md5( t _cookie_quotet _make_cookie_domaint _cookie_parse_impl( t to_unicodet iteritemst text_typet string_typest try_coerce_nativet to_bytest PY2t integer_typest latin1s* ([^\s;,]+)(?:[^,]*?;\s*q=(\d*(?:\.\d+)?))?sM !#$%&'*+-.0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ^_`abcdefghijklmnopqrstuvwxyz|~s& ([Ww]/)?(?:"(.*?)"|(.*?))(?:\s*,\s*|$)s ()<>@,;:"/[]?={} s "[^"\\]*(?:\\.[^"\\]*)*"s* ;\s*(%s|[^\s;=]+)\s*(?:=\s*(%s|[^;]+))?\s*t allows content-encodings content-languages content-lengths content-locations content-md5s content-ranges content-typet expiress last-modifiedt connections keep-alives proxy-authenticates proxy-authorizationt tet trailers transfer-encodingt upgradet Continueid s Switching Protocolsie t Processingif t OKi� t Createdi� t Acceptedi� s Non Authoritative Informationi� s No Contenti� s Reset Contenti� s Partial Contenti� s Multi Statusi� s IM Usedi� s Multiple Choicesi, s Moved Permanentlyi- t Foundi. s See Otheri/ s Not Modifiedi0 s Use Proxyi1 s Temporary Redirecti3 s Bad Requesti� t Unauthorizedi� s Payment Requiredi� t Forbiddeni� s Not Foundi� s Method Not Allowedi� s Not Acceptablei� s Proxy Authentication Requiredi� s Request Timeouti� t Conflicti� t Gonei� s Length Requiredi� s Precondition Failedi� s Request Entity Too Largei� s Request URI Too Longi� s Unsupported Media Typei� s Requested Range Not Satisfiablei� s Expectation Failedi� s I'm a teapoti� s Unprocessable Entityi� t Lockedi� s Failed Dependencyi� s Upgrade Requiredi� s Precondition Requiredi� s Too Many Requestsi� s Request Header Fields Too Largei� s Retry Withi� s Internal Server Errori� s Not Implementedi� s Bad Gatewayi� s Service Unavailablei� s Gateway Timeouti� s HTTP Version Not Supportedi� s Insufficient Storagei� s Not Extendedi� c C s t | t � r | S| j d � S( s8 coerce wsgi unicode represented bytes to real ones R ( t isinstancet bytest encode( t data( ( s< /opt/imh-python/lib/python2.7/site-packages/werkzeug/http.pyt wsgi_to_bytesy s c C s$ t | t � r | S| j d � Sd S( NR ( R$ t strt decode( R' ( ( s< /opt/imh-python/lib/python2.7/site-packages/werkzeug/http.pyt bytes_to_wsgi� s t c C s| t | t � r t | � } n t | � } | r\ t t | � B} t | � j | � r\ | Sn d | j d d � j d d � S( s Quote a header value if necessary. .. versionadded:: 0.5 :param value: the value to quote. :param extra_chars: a list of extra characters to skip quoting. :param allow_token: if this is enabled token values are returned unchanged. s "%s"s \s \\t "s \"( R$ R% R+ R) t _token_charst sett issubsett replace( t valuet extra_charst allow_tokent token_chars( ( s< /opt/imh-python/lib/python2.7/site-packages/werkzeug/http.pyt quote_header_value� s c C sq | rm | d | d k o% d k n rm | d d !} | sN | d d k rm | j d d � j d d � Sn | S( s� Unquotes a header value.

The `cls` parameter was added. :param header: the header to be used to parse the cookie. Alternatively this can be a WSGI environment. :param charset: the charset for the cookie values. :param errors: the error behavior for the charset decoding. :param cls: an optional dict class to use. If this is not specified or `None` the default :class:`TypeConversionDict` is used. t HTTP_COOKIER, R R1 c 3 sb x[ t � � D]M \ } } t | � � d t �} t | � � d t �} t | � | f Vq Wd S( Nt allow_none_charset( R R R� R ( R? t val( t charsett errorsR< ( s< /opt/imh-python/lib/python2.7/site-packages/werkzeug/http.pyt _parse_pairsX s N( R$ RA Rz R9 R R& t TypeConversionDict( R< R� R� RL R� ( ( R� R� R< s< /opt/imh-python/lib/python2.7/site-packages/werkzeug/http.pyt parse_cookie6 s R� c C s t | | � } t | | � } | d k r< t | | � } n t | � } t | t � rv | j d d d | j } n | d k r� t | t � s� t | � } q� n. | d k r� | r� t t t � | � � } n | d t | � g } xd | t f d | t f d | t f d | d f d | d f d | t f f D]� \ } } } | d k rn| r7| j | � q7q7n | d k r�q7n t | � } t | t t f � s�t t | � | � } n | r�t | � } n | d | 7} | j t | � � q7Wd j | � } t s| j d � } n | S( s� Creates a new Set-Cookie header without the ``Set-Cookie`` prefix The parameters are the same as in the cookie Morsel object in the Python standard library but it accepts unicode data, too. On Python 3 the return value of this function will be a unicode string, on Python 2 it will be a native string. In both cases the return value is usually restricted to ascii as the vast majority of values are properly escaped, but that is no guarantee. If a unicode string is returned it's tunneled through latin1 as required by PEP 3333. The return value is not ASCII safe if the key contains unicode characters. This is technically against the specification but happens in the wild. It's strongly recommended to not use non-ASCII values for the keys. :param max_age: should be a number of seconds, or `None` (default) if the cookie should last only as long as the client's browser session. Additionally `timedelta` objects are accepted, too. :param expires: should be a `datetime` object or unix timestamp. :param path: limits the cookie to a given path, per default it will span the whole domain. :param domain: Use this if you want to set a cross-domain cookie. For example, ``domain=".example.com"`` will set a cookie that is readable by the domain ``www.example.com``, ``foo.example.com`` etc. Otherwise, a cookie will only be readable by the domain that set it. :param secure: The cookie will only be available via HTTPS :param httponly: disallow JavaScript to access the cookie. This is an extension to the cookie standard and probably not supported by all browsers. :param charset: the encoding for unicode values. :param sync_expires: automatically set expires if max_age is defined but expires not. i< i RJ t Domaint Expiress Max-Aget Securet HttpOnlyt Paths ; R N( R R9 t iri_to_uriR R$ R t daysR� R R� R R R� R� R: t bytearrayR% R R; R R* ( R?
