Constructor Detail

def self.from_client_headers(headers) : self #

Creates a new instance by parsing the Cookie headers in the given HTTP::Headers.

See HTTP::Client::Response#cookies.


[View source]
def self.from_headers(headers) : self #

Creates a new instance by parsing the Cookie and Set-Cookie headers in the given HTTP::Headers.

See HTTP::Request#cookies and HTTP::Client::Response#cookies.

DEPRECATED Use .from_client_headers or .from_server_headers instead.


[View source]
def self.from_server_headers(headers) : self #

Creates a new instance by parsing the Set-Cookie headers in the given HTTP::Headers.

See HTTP::Request#cookies.


[View source]
def self.new #

Creates a new empty instance.

Instance Method Detail

def <<(cookie : Cookie) #

Adds the given cookie to this collection, overrides an existing cookie with the same name if present.

response.cookies << HTTP::Cookie.new("foo", "bar", http_only: true)

[View source]
def [](key) : Cookie #

Gets the current HTTP::Cookie for the given key.

request.cookies["foo"].value # => "bar"

[View source]
def []=(key, value : String) #

Sets a new cookie in the collection with a string value. This creates a never expiring, insecure, not HTTP-only cookie with no explicit domain restriction and no path.

require "http/client"

request = HTTP::Request.new "GET", "/"
request.cookies["foo"] = "bar"

[View source]
def []=(key, value : Cookie) #

Sets a new cookie in the collection to the given HTTP::Cookie instance. The name attribute must match the given key, else ArgumentError is raised.

require "http/client"

response = HTTP::Client::Response.new(200)
response.cookies["foo"] = HTTP::Cookie.new("foo", "bar", "/admin", Time.utc + 12.hours, secure: true)

[View source]
def []?(key) : Cookie | Nil #

Gets the current HTTP::Cookie for the given key or nil if none is set.

require "http/client"

request = HTTP::Request.new "GET", "/"
request.cookies["foo"]? # => nil
request.cookies["foo"] = "bar"
request.cookies["foo"]?.try &.value # > "bar"

[View source]
def add_request_headers(headers) #

Adds Cookie headers for the cookies in this collection to the given HTTP::Headers instance and returns it. Removes any existing Cookie headers in it.


[View source]
def add_response_headers(headers) #

Adds Set-Cookie headers for the cookies in this collection to the given HTTP::Headers instance and returns it. Removes any existing Set-Cookie headers in it.


[View source]
def clear : Hash(String, HTTP::Cookie) #

Clears the collection, removing all cookies.


[View source]
def delete(key) : Cookie | Nil #

Deletes and returns the HTTP::Cookie for the specified key, or returns nil if key cannot be found in the collection. Note that key should match the name attribute of the desired HTTP::Cookie.


[View source]
def each(& : Cookie -> ) #

Yields each HTTP::Cookie in the collection.


[View source]
def each #

Returns an iterator over the cookies of this collection.


[View source]
def empty? : Bool #

Whether the collection contains any cookies.


[View source]
def fill_from_client_headers(headers) : self #

Filling cookies by parsing the Cookie headers in the given HTTP::Headers.


[View source]
def fill_from_headers(headers) #

Filling cookies by parsing the Cookie and Set-Cookie headers in the given HTTP::Headers.

DEPRECATED Use #fill_from_client_headers or #fill_from_server_headers instead.


[View source]
def fill_from_server_headers(headers) : self #

Filling cookies by parsing the Set-Cookie headers in the given HTTP::Headers.


[View source]
def has_key?(key) : Bool #

Returns true if a cookie with the given key exists.

request.cookies.has_key?("foo") # => true

[View source]
def size : Int32 #

Returns the number of cookies contained in this collection.


[View source]
def to_h : Hash(String, Cookie) #

Returns this collection as a plain Hash.
