Constructor Details
#initialize(options = nil) ⇒ CookieJar
Generates a new cookie jar.
Available option keywords are as below:
:store : The store class that backs this jar. (default: ‘:hash`) A symbol or an instance of a store class is accepted. Symbols are mapped to store classes, like `:hash` to HTTP::CookieJar::HashStore and `:mozilla` to HTTP::CookieJar::MozillaStore.
Any options given are passed through to the initializer of the specified store class. For example, the ‘:mozilla` (HTTP::CookieJar::MozillaStore) store class requires a `:filename` option. See individual store classes for details.

Instance Method Details
#add(cookie) ⇒ Object Also known as: <<
Adds a cookie to the jar if it is acceptable, and returns self in any case. A given cookie must have domain and path attributes set, or ArgumentError is raised.
Whether a cookie with the ‘for_domain` flag on overwrites another with the flag off or vice versa depends on the store used. See individual store classes for that matter.
### Compatibility Note for Mechanize::Cookie users
In HTTP::Cookie, each cookie object can store its origin URI (cf. #origin). While the origin URI of a cookie can be set manually by #origin=, one is typically given in its generation. To be more specific, HTTP::Cookie.new takes an ‘:origin` option and HTTP::Cookie.parse takes one via the second argument.
# Mechanize::Cookie
jar.add(origin, )
jar.add!() # no acceptance check is performed
# HTTP::Cookie
jar.origin = origin
jar.add() # acceptance check is performed

# File 'lib/http/cookie_jar.rb', line 90 def add() @store.add() if begin .acceptable? rescue RuntimeError => e raise ArgumentError, e. end self end |
#cleanup(session = false) ⇒ Object
Removes expired cookies and returns self. If ‘session` is true, all session cookies are removed as well.
317 318 319 320 |
# File 'lib/http/cookie_jar.rb', line 317 def cleanup(session = false) @store.cleanup session self end |
#clear ⇒ Object
Clears the cookie jar and returns self.
310 311 312 313 |
# File 'lib/http/cookie_jar.rb', line 310 def clear @store.clear self end |
#cookies(url = nil) ⇒ Object
Gets an array of cookies sorted by the path and creation time. If ‘url` is given, only ones that should be sent to the URL/URI are selected, with the access time of each of them updated.
115 116 117 |
# File 'lib/http/cookie_jar.rb', line 115 def (url = nil) each(url).sort end |
#delete(cookie) ⇒ Object
Deletes a cookie that has the same name, domain and path as a given cookie from the jar and returns self.
How the ‘for_domain` flag value affects the set of deleted cookies depends on the store used. See individual store classes for that matter.
107 108 109 110 |
# File 'lib/http/cookie_jar.rb', line 107 def delete() @store.delete() self end |
#each(uri = nil, &block) ⇒ Object
Iterates over all cookies that are not expired in no particular order.
An optional argument ‘uri` specifies a URI/URL indicating the destination of the cookies being selected. Every cookie yielded should be good to send to the given URI, i.e. cookie.valid_for_uri?(uri) evaluates to true.
If (and only if) the ‘uri` option is given, last access time of each cookie is updated to the current time.

#empty?(url = nil) ⇒ Boolean
Tests if the jar is empty. If ‘url` is given, tests if there is no cookie for the URL.

#initialize_copy(other) ⇒ Object
The copy constructor. Not all backend store classes support cloning.

#load(readable, *options) ⇒ Object
call-seq:
jar.load(filename_or_io, **)
jar.load(filename_or_io, format = :yaml, **)
Loads cookies recorded in a file or an IO in the format specified into the jar and returns self. If a given object responds to #read it is taken as an IO, or taken as a filename otherwise.
Available option keywords are below:
-
‘:format`
<dl class="rdoc-list note-list"> <dt>:yaml</dt> <dd>YAML structure (default)</dd> <dt>:cookiestxt</dt> <dd>Mozilla's cookies.txt format</dd> </dl>
All options given are passed through to the underlying cookie saver module’s constructor.

#parse(set_cookie, origin, options = nil) ⇒ Object
Parses a Set-Cookie field value ‘set_cookie` assuming that it is sent from a source URL/URI `origin`, and adds the cookies parsed as valid and considered acceptable to the jar. Returns an array of cookies that have been added.
If a block is given, it is called for each cookie and the cookie is added only if the block returns a true value.
‘jar.parse(set_cookie, origin)` is a shorthand for this:
HTTP::Cookie.parse(, origin) { ||
jar.add()
}
See HTTP::Cookie.parse for available options.

#save(writable, *options) ⇒ Object
call-seq:
jar.save(filename_or_io, **)
jar.save(filename_or_io, format = :yaml, **)
Saves the cookie jar into a file or an IO in the format specified and returns self. If a given object responds to #write it is taken as an IO, or taken as a filename otherwise.
Available option keywords are below:
-
‘:format`
<dl class="rdoc-list note-list"> <dt>:yaml</dt> <dd>YAML structure (default)</dd> <dt>:cookiestxt</dt> <dd>Mozilla's cookies.txt format</dd> </dl>

All options given are passed through to the underlying cookie saver module’s constructor.
