Here's a sample session to show how to use this module. At the moment, this is the only documentation. The Basics ---------- Importing is easy... >>> from http import cookies Most of the time you start by creating a cookie. >>> C = cookies.SimpleCookie() Once you've created your Cookie, you can add values just as if it were a dictionary. >>> C = cookies.SimpleCookie() >>> 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 the appropriate format for a Set-Cookie: header. This is the default behavior. You can change the header and printed attributes by using the .output() function >>> C = cookies.SimpleCookie() >>> 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 a CGI script, you would use this method to extract the cookies from the HTTP_COOKIE environment variable. >>> C = cookies.SimpleCookie() >>> 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 cookies within a string. Escaped quotation marks, nested semicolons, and other such trickeries do not confuse it. >>> C = cookies.SimpleCookie() >>> 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 2109 Cookie attributes. Here's an example which sets the Path attribute. >>> C = cookies.SimpleCookie() >>> C["oreo"] = "doublestuff" >>> C["oreo"]["path"] = "/" >>> print(C) Set-Cookie: oreo=doublestuff; Path=/ Each dictionary element has a 'value' attribute, which gives you back the value associated with the key. >>> C = cookies.SimpleCookie() >>> C["twix"] = "none for you" >>> C["twix"].value 'none for you' The SimpleCookie expects that all values should be standard strings. Just to be sure, SimpleCookie invokes the str() builtin to convert the value to a string, when the values are set dictionary-style. >>> C = cookies.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' Finis.

In a cookie, each such pair may have several attributes, so this class is used to keep the attributes associated with the appropriate key,value pair. This class also includes a coded_value attribute, which is used to hold the network representation of the value. This is most useful when Python objects are pickled for network transit. expiresZPathCommentZDomainzMax-AgeZSecureZHttpOnlyZVersion)r/pathcommentZdomainzmax-agesecurehttponlyversionr3r4cCs4d|_|_|_x|jD]}t||dqWdS)Nr)_key_value _coded_value _reserveddict __setitem__)selfkeyr r r __init__ s zMorsel.__init__cCs|jS)N)r6)r<r r r r=(sz Morsel.keycCs|jS)N)r7)r<r r r value,sz Morsel.valuecCs|jS)N)r8)r<r r r coded_value0szMorsel.coded_valuecCs2|}||jkr td|ft|||dS)NzInvalid attribute %r)lowerr9rr:r;)r<KVr r r r;4s zMorsel.__setitem__NcCs.|}||jkr td|ft|||S)NzInvalid attribute %r)rAr9rr: setdefault)r<r=valr r r rD:s zMorsel.setdefaultcCs>t|tstSt||o<|j|jko<|j|jko<|j|jkS)N) isinstancer.NotImplementedr:__eq__r7r6r8)r<morselr r r rH@s     z Morsel.__eq__cCs$t}t|||j|j|S)N)r.r:update__dict__)r<rIr r r copyJs z Morsel.copycCsVi}x@t|D]0\}}|}||jkr:td|f|||<qWt||dS)NzInvalid attribute %r)r:itemsrAr9rrJ)r<valuesdatar=rEr r r rJPs  z Morsel.updatecCs||jkS)N)rAr9)r<rBr r r isReservedKeyYszMorsel.isReservedKeycCsH||jkrtd|ft|s2td|f||_||_||_dS)Nz Attempt to set a reserved key %rzIllegal key %r)rAr9rrr6r7r8)r<r=rEZ coded_valr r r set\sz Morsel.setcCs|j|j|jdS)N)r=r?r@)r6r7r8)r<r r r __getstate__gszMorsel.__getstate__cCs"|d|_|d|_|d|_dS)Nr=r?r@)r6r7r8)r<stater r r __setstate__ns  zMorsel.__setstate__ Set-Cookie:cCsd|||fS)Nz%s %s) OutputString)r<attrsheaderr r r outputssz Morsel.outputcCsd|jj|fS)Nz<%s: %s>) __class__rrV)r<r r r __repr__xszMorsel.__repr__cCsd||ddS)Nz rz\")rVreplace)r<rWr r r js_output{szMorsel.js_outputcCs(g}|j}|d|j|jf|dkr,|j}t|}x|D]\}}|dkrPq>||krZq>|dkrt|tr|d|j|t|fq>|dkrt|tr|d|j||fq>|dkrt|t r|d|j|t |fq>||j kr|r|t |j|q>|d|j||fq>Wt |S)Nz%s=%srr/zmax-agez%s=%dr2) r r=r@r9sortedrMrFr#r-rr_flags_semispacejoin)r<rWresultr rMr=r?r r r rVs,  zMorsel.OutputString)N)NrU)N)N)rrr __doc__r9r_r>propertyr=r?r@r;rDrHobject__ne__rLrJrPrQrRrTrY__str__r[r]rVr r r r r.s:        r.z,\w\d!#%&'~_`><@,:/\$\*\+\-\.\^\|\)\(\?\}\{\=z\[\]z \s* # Optional whitespace at start of cookie (?P # Start of group 'key' [a ]+? # Any word of at least one letter ) # End of group 'key' ( # Optional group: there may not be a value. \s*=\s* # Equal Sign (?P # Start of group 'val' "(?:[^\\"]|\\.)*" # Any doublequoted string | # or \w{3},\s[\w\d\s-]{9,11}\s[\d:]{8}\sGMT # Special case for "expires" attr | # or [a-]* # Any word or empty string ) # End of group 'val' )? # End of optional value group \s* # Any number of spaces.
