The Basics---------- Importing is easy.. >>> import Cookie Most of the time you start by creating a cookie. Cookies come inthree flavors, each with slightly different encoding semantics, butmore on that later. >>> C = Cookie.SimpleCookie() >>> C = Cookie.SerialCookie() >>> C = Cookie.SmartCookie() [Note: Long-time users of Cookie.py will remember usingCookie.Cookie() to create an Cookie object. Although deprecated, itis still supported by the code. See the Backward Compatibility notesfor more information.] Once you've created your Cookie, you can add values just as if it werea dictionary. >>> C = Cookie.SmartCookie() >>> C["fig"] = "newton" >>> C["sugar"] = "wafer" >>> C.output() 'Set-Cookie: fig=newton\r\nSet-Cookie: sugar=wafer' Notice that the printable representation of a Cookie is theappropriate format for a Set-Cookie: header. This is thedefault behavior. You can change the header and printedattributes by using the .output() function >>> C = Cookie.SmartCookie() >>> C["rocky"] = "road" >>> C["rocky"]["path"] = "/cookie" >>> print C.output(header="Cookie:") Cookie: rocky=road; Path=/cookie >>> print C.output(attrs=[], header="Cookie:") Cookie: rocky=road The load() method of a Cookie extracts cookies from a string. In aCGI script, you would use this method to extract the cookies from theHTTP_COOKIE environment variable. >>> C = Cookie.SmartCookie() >>> C.load("chips=ahoy; vienna=finger") >>> C.output() 'Set-Cookie: chips=ahoy\r\nSet-Cookie: vienna=finger' The load() method is darn-tootin smart about identifying cookieswithin a string. Escaped quotation marks, nested semicolons, and othersuch trickeries do not confuse it. >>> C = Cookie.SmartCookie() >>> C.load('keebler="E=everybody; L=\\"Loves\\"; fudge=\\012;";') >>> print C Set-Cookie: keebler="E=everybody; L=\"Loves\"; fudge=\012;" Each element of the Cookie also supports all of the RFC 2109Cookie attributes. Here's an example which sets the Pathattribute. >>> C = Cookie.SmartCookie() >>> C["oreo"] = "doublestuff" >>> C["oreo"]["path"] = "/" >>> print C Set-Cookie: oreo=doublestuff; Path=/ Each dictionary element has a 'value' attribute, which gives youback the value associated with the key. >>> C = Cookie.SmartCookie() >>> C["twix"] = "none for you" >>> C["twix"].value 'none for you' A Bit More Advanced------------------- As mentioned before, there are three different flavors of Cookieobjects, each with different encoding/decoding semantics. Thissection briefly discusses the differences. SimpleCookie The SimpleCookie expects that all values should be standard strings.Just to be sure, SimpleCookie invokes the str() builtin to convertthe value to a string, when the values are set dictionary-style. >>> C = Cookie.SimpleCookie() >>> C["number"] = 7 >>> C["string"] = "seven" >>> C["number"].value '7' >>> C["string"].value 'seven' >>> C.output() 'Set-Cookie: number=7\r\nSet-Cookie: string=seven' SerialCookie The SerialCookie expects that all values should be serialized usingcPickle (or pickle, if cPickle isn't available). As a result ofserializing, SerialCookie can save almost any Python object to avalue, and recover the exact same object when the cookie has beenreturned. (SerialCookie can yield some strange-looking cookievalues, however.) >>> C = Cookie.SerialCookie() >>> C["number"] = 7 >>> C["string"] = "seven" >>> C["number"].value 7 >>> C["string"].value 'seven' >>> C.output() 'Set-Cookie: number="I7\\012."\r\nSet-Cookie: string="S\'seven\'\\012p1\\012."' Be warned, however, if SerialCookie cannot de-serialize a value (becauseit isn't a valid pickle'd object), IT WILL RAISE AN EXCEPTION. SmartCookie The SmartCookie combines aspects of each of the other two flavors.When setting a value in a dictionary-fashion, the SmartCookie willserialize (ala cPickle) the value *if and only if* it isn't aPython string. String objects are *not* serialized. Similarly,when the load() method parses out values, it attempts to de-serializethe value. If it fails, then it fallsback to treating the valueas a string. >>> C = Cookie.SmartCookie() >>> C["number"] = 7 >>> C["string"] = "seven" >>> C["number"].value 7 >>> C["string"].value 'seven' >>> C.output() 'Set-Cookie: number="I7\\012."\r\nSet-Cookie: string=seven' Backwards Compatibility----------------------- In order to keep compatibilty with earlier versions of Cookie.py,it is still possible to use Cookie.Cookie() to create a Cookie. Infact, this simply returns a SmartCookie. >>> C = Cookie.Cookie() >>> print C.__class__.__name__ SmartCookie Finis.""" #"# ^# |----helps out font-lock ## Import our required modules#import string try: from cPickle import dumps, loadsexcept ImportError: from pickle import dumps, loads import re, warnings __all__ = ["CookieError","BaseCookie","SimpleCookie","SerialCookie", "SmartCookie","Cookie"] _nulljoin = ''.join_semispacejoin = '; '.join_spacejoin = ' '.join ## Define an exception visible to External modules#class CookieError(Exception): pass # These quoting routines conform to the RFC2109 specification, which in# turn references the character definitions from RFC2068.
