For more information about cookies refer to + and +. This module also implements the +new style cookies described in I. +The two variants of cookies are supposed to be able to coexist happily. + +Instances of the class I are able to store a collection +of Set-Cookie2: and Set-Cookie: headers and are able to use this +information to initialize Cookie-headers in I objects. +The state of a I object can be saved in and restored from +files. + +=head1 METHODS + +The following methods are provided: + +=over 4 + +=item $cookie_jar = HTTP::Cookies->new + +The constructor takes hash style parameters. The following +parameters are recognized: + + file: name of the file to restore cookies from and save cookies to + autosave: save during destruction (bool) + ignore_discard: save even cookies that are requested to be discarded (bool) + hide_cookie2: do not add Cookie2 header to requests + +Future parameters might include (not yet implemented): + + max_cookies 300 + max_cookies_per_domain 20 + max_cookie_size 4096 + + no_cookies list of domain names that we never return cookies to + +=item $cookie_jar->add_cookie_header( $request ) + +The add_cookie_header() method will set the appropriate Cookie:-header +for the I object given as argument. The $request must +have a valid url attribute before this method is called. + +=item $cookie_jar->extract_cookies( $response ) + +The extract_cookies() method will look for Set-Cookie: and +Set-Cookie2: headers in the I object passed as +argument. Any of these headers that are found are used to update +the state of the $cookie_jar. + +=item $cookie_jar->set_cookie( $version, $key, $val, $path, $domain, $port, $path_spec, $secure, $maxage, $discard, \%rest ) + +The set_cookie() method updates the state of the $cookie_jar. The +$key, $val, $domain, $port and $path arguments are strings. The +$path_spec, $secure, $discard arguments are boolean values. The $maxage +value is a number indicating number of seconds that this cookie will +live. A value <= 0 will delete this cookie. %rest defines +various other attributes like "Comment" and "CommentURL". + +=item $cookie_jar->save + +=item $cookie_jar->save( $file ) + +This method file saves the state of the $cookie_jar to a file. +The state can then be restored later using the load() method. If a +filename is not specified we will use the name specified during +construction. If the attribute I is set, then we +will even save cookies that are marked to be discarded. + +The default is to save a sequence of "Set-Cookie3" lines. +"Set-Cookie3" is a proprietary LWP format, not known to be compatible +with any browser. The I sub-class can +be used to save in a format compatible with Netscape. + +=item $cookie_jar->load + +=item $cookie_jar->load( $file ) + +This method reads the cookies from the file and adds them to the +$cookie_jar. The file must be in the format written by the save() +method. + +=item $cookie_jar->revert + +This method empties the $cookie_jar and re-loads the $cookie_jar +from the last save file. + +=item $cookie_jar->clear + +=item $cookie_jar->clear( $domain ) + +=item $cookie_jar->clear( $domain, $path ) + +=item $cookie_jar->clear( $domain, $path, $key ) + +Invoking this method without arguments will empty the whole +$cookie_jar. If given a single argument only cookies belonging to +that domain will be removed. If given two arguments, cookies +belonging to the specified path within that domain are removed. If +given three arguments, then the cookie with the specified key, path +and domain is removed. + +=item $cookie_jar->clear_temporary_cookies + +Discard all temporary cookies. Scans for all cookies in the jar +with either no expire field or a true C flag. To be +called when the user agent shuts down according to RFC 2965. + +=item $cookie_jar->scan( \&callback ) + +The argument is a subroutine that will be invoked for each cookie +stored in the $cookie_jar. The subroutine will be invoked with +the following arguments: + + 0 version + 1 key + 2 val + 3 path + 4 domain + 5 port + 6 path_spec + 7 secure + 8 expires + 9 discard + 10 hash + +=item $cookie_jar->as_string + +=item $cookie_jar->as_string( $skip_discardables ) + +The as_string() method will return the state of the $cookie_jar +represented as a sequence of "Set-Cookie3" header lines separated by +"\n". If $skip_discardables is TRUE, it will not return lines for +cookies with the I attribute. + +=back + +=head1 SEE ALSO + +L, L + +=head1 COPYRIGHT + +Copyright 1997-2002 Gisle Aas + +This library is free software; you can redistribute it and/or +modify it under the same terms as Perl itself. + diff --git a/lib/HTTP/Cookies/Microsoft.pm b/lib/HTTP/Cookies/Microsoft.pm new file mode 100644 index 0000000..9c69fa3 --- /dev/null +++ b/lib/HTTP/Cookies/Microsoft.pm @@ -0,0 +1,329 @@ +package HTTP::Cookies::Microsoft; + +use strict; + +use vars qw(@ISA $VERSION); + +$VERSION = "6.00"; + +require HTTP::Cookies; +@ISA=qw(HTTP::Cookies); + +sub load_cookies_from_file +{ + my ($file) = @_; + my @cookies; + my ($key, $value, $domain_path, $flags, $lo_expire, $hi_expire); + my ($lo_create, $hi_create, $sep); + + open(COOKIES, $file) || return; + + while ($key = ) + { + chomp($key); + chomp($value = ); + chomp($domain_path= ); + chomp($flags = ); # 0x0001 bit is for secure + chomp($lo_expire = ); + chomp($hi_expire = ); + chomp($lo_create = ); + chomp($hi_create = ); + chomp($sep = ); + + if (!defined($key) || !defined($value) || !defined($domain_path) || + !defined($flags) || !defined($hi_expire) || !defined($lo_expire) || + !defined($hi_create) || !defined($lo_create) || !defined($sep) || + ($sep ne '*')) + { + last; + } + + if ($domain_path =~ /^([^\/]+)(\/.*)$/) + { + my $domain = $1; + my $path = $2; + + push(@cookies, {KEY => $key, VALUE => $value, DOMAIN => $domain, + PATH => $path, FLAGS =>$flags, HIXP =>$hi_expire, + LOXP => $lo_expire, HICREATE => $hi_create, + LOCREATE => $lo_create}); + } + } + + return \@cookies; +} + +sub get_user_name +{ + use Win32; + use locale; + my $user = lc(Win32::LoginName()); + + return $user; +} + +# MSIE stores create and expire times as Win32 FILETIME, +# which is 64 bits of 100 nanosecond intervals since Jan 01 1601 +# +# But Cookies code expects time in 32-bit value expressed +# in seconds since Jan 01 1970 +# +sub epoch_time_offset_from_win32_filetime +{ + my ($high, $low) = @_; + + #-------------------------------------------------------- + # USEFUL CONSTANT + #-------------------------------------------------------- + # 0x019db1de 0xd53e8000 is 1970 Jan 01 00:00:00 in Win32 FILETIME + # + # 100 nanosecond intervals == 0.1 microsecond intervals + + my $filetime_low32_1970 = 0xd53e8000; + my $filetime_high32_1970 = 0x019db1de; + + #------------------------------------ + # ALGORITHM + #------------------------------------ + # To go from 100 nanosecond intervals to seconds since 00:00 Jan 01 1970: + # + # 1.
