class Cookie |
| |
HTTP Cookie.
This class represents both Netscape and RFC 2965 cookies.
This is deliberately a very simple class. It just holds attributes. It's
possible to construct Cookie instances that don't comply with the cookie
standards. CookieJar.make_cookies is the factory function for Cookie
objects -- it deals with cookie parsing, supplying defaults, and
normalising to the representation used in this class. CookiePolicy is
responsible for checking them to see whether they should be accepted from
and returned to the server.
Note that the port may be present in the headers, but unspecified ("Port"
rather than"Port=80", for example); if this is the case, port is None.

class CookieJar |
| |
Collection of HTTP cookies.
You may not need to know about this class: try
urllib2.build_opener(HTTPCookieProcessor).open(url).
|
| |
Methods defined here:
- __init__(self, policy=None)
- __iter__(self)
- __len__(self)
- Return number of contained cookies.
- __repr__(self)
- __str__(self)
- add_cookie_header(self, request)
- Add correct Cookie: header to request (urllib2.Request object).
The Cookie2 header is also added unless policy.hide_cookie2 is true.
- clear(self, domain=None, path=None, name=None)
- Clear some cookies.
Invoking this method without arguments will clear all cookies. 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 name, path and domain is removed.
Raises KeyError if no matching cookie exists.
- clear_expired_cookies(self)
- Discard all expired cookies.
You probably don't need to call this method: expired cookies are never
sent back to the server (provided you're using DefaultCookiePolicy),
this method is called by CookieJar itself every so often, and the
.save() method won't save expired cookies anyway (unless you ask
otherwise by passing a true ignore_expires argument).
- clear_session_cookies(self)
- Discard all session cookies.
Note that the .save() method won't save session cookies anyway, unless
you ask otherwise by passing a true ignore_discard argument.
- extract_cookies(self, response, request)
- Extract cookies from response, where allowable given the request.
- make_cookies(self, response, request)
- Return sequence of Cookie objects extracted from response object.
- set_cookie(self, cookie)
- Set a cookie, without checking whether or not it should be set.
- set_cookie_if_ok(self, cookie, request)
- Set a cookie if policy says it's OK to do so.
- set_policy(self, policy)

|
class CookiePolicy |
| |
Defines which cookies get accepted from and returned to server.
May also modify cookies, though this is probably a bad idea.
The subclass DefaultCookiePolicy defines the standard rules for Netscape
and RFC 2965 cookies -- override that if you want a customised policy.
|
| |
Methods defined here:
- domain_return_ok(self, domain, request)
- Return false if cookies should not be returned, given cookie domain.
- path_return_ok(self, path, request)
- Return false if cookies should not be returned, given cookie path.
- return_ok(self, cookie, request)
- Return true if (and only if) cookie should be returned to server.
- set_ok(self, cookie, request)
- Return true if (and only if) cookie should be accepted from server.
Currently, pre-expired cookies never get this far -- the CookieJar
class deletes such cookies itself.
|

class LWPCookieJar(cookielib.FileCookieJar) |
| |
The LWPCookieJar saves a sequence of "Set-Cookie3" lines.
"Set-Cookie3" is the format used by the libwww-perl libary, not known
to be compatible with any browser, but which is easy to read and
doesn't lose information about RFC 2965 cookies.

class MozillaCookieJar(cookielib.FileCookieJar) |
| |
WARNING: you may want to backup your browser's cookies file if you use
this class to save cookies. I *think* it works, but there have been
bugs in the past!
This class differs from CookieJar only in the format it uses to save and
load cookies to and from a file. This class uses the Mozilla/Netscape
`cookies.txt' format. lynx uses this file format, too.
Don't expect cookies saved while the browser is running to be noticed by
the browser (in fact, Mozilla on unix will overwrite your saved cookies if
you change them on disk while it's running; on Windows, you probably can't
save at all while the browser is running).
Note that the Mozilla/Netscape format will downgrade RFC2965 cookies to
Netscape cookies on saving.
In particular, the cookie version and port number information is lost,
together with information about whether or not Path, Port and Discard were
specified by the Set-Cookie2 (or Set-Cookie) header, and whether or not the
domain as set in the HTTP header started with a dot (yes, I'm aware some
domains in Netscape files start with a dot and some don't -- trust me, you
really don't want to know any more about this).
Note that though Mozilla and Netscape use the same format, they use
slightly different headers. The class saves cookies using the Netscape
header by default (Mozilla can cope with that).
