##
Constructors

- .new(name : String, value : String, path : String | Nil = nil, expires : Time | Nil = nil, domain : String | Nil = nil, secure : Bool | Nil = nil, http_only : Bool = false, samesite : SameSite | Nil = nil, extension : String | Nil = nil, max_age : Time::Span | Nil = nil, creation_time : Time = Time.utc)

Constructor Detail

def self.new(name : String, value : String, path : String | Nil = nil, expires : Time | Nil = nil, domain : String | Nil = nil, secure : Bool | Nil = nil, http_only : Bool = false, samesite : SameSite | Nil = nil, extension : String | Nil = nil, max_age : Time::Span | Nil = nil, creation_time : Time = Time.utc) #

Creates a new `Cookie` instance.

Raises `IO::Error` if name or value are invalid as per RFC 6265 §4.1.1. Raises `ArgumentError` if name has a security prefix but the requirements are not met as per RFC 6265 bis §4.1.3. Alternatively, if name has a security prefix, and the related properties are `nil`, the prefix will automatically be applied to the cookie.

Instance Method Detail

def ==(other : self) #
Description copied from class Reference

Returns `true` if this reference is the same as other. Invokes `same?`.

def creation_time : Time #
def domain : String | Nil #
def domain=(domain : String | Nil) #
def expiration_time : Time | Nil #

Returns the expiration time of this cookie.

def expired?(time_reference = Time.utc) : Bool #

Returns the expiration status of this cookie as a `Bool`.

time_reference can be passed to use a different reference time for comparison. Default is the current time (`Time.utc`).

def expires : Time | Nil #
def expires=(expires : Time | Nil) #
def extension : String | Nil #
def extension=(extension : String | Nil) #
def hash(hasher) #
Description copied from class Reference

See `Object#hash(hasher)`

def http_only : Bool #
def http_only=(http_only : Bool) #
def max_age : Time::Span | Nil #
def max_age=(max_age : Time::Span | Nil) #
def name : String #
def name=(name : String) #

Sets the name of this cookie.

Raises `IO::Error` if the value is invalid as per RFC 6265 §4.1.1.

def path : String | Nil #
def path=(path : String | Nil) #
def samesite : SameSite | Nil #
def samesite=(samesite : SameSite | Nil) #
def secure : Bool #

Returns `true` if this cookie has the Secure flag.

def secure=(secure : Bool) : Bool #
def to_cookie_header(io) : Nil #
def to_cookie_header : String #
def to_set_cookie_header : String #
def valid? : Bool #

Returns `false` if `#name` has a security prefix but the requirements are not met as per RFC 6265 bis §4.1.3, otherwise returns `true`.

def validate! : self #

Raises `ArgumentError` if `self` is not `#valid?`.

def value : String #
def value=(value : String) #

Sets the value of this cookie.

Raises `IO::Error` if the value is invalid as per RFC 6265 §4.1.1.
