struct HTTP::Headers
inherits Struct
¶
A Hash-like object that holds HTTP headers.
Two headers are considered the same if their downcase representation is the same
(in which _ is the downcase version of -).

Class methods¶
Methods¶
#==(other : self)
¶
(other : self)
Equality operator.
Returns true if other is equal to self.
Keys are matched case-insensitive. String values are treated equal to an array values with the same string as single element.
HTTP::Headers{"Foo" => "bar"} == HTTP::Headers{"Foo" => "bar"} # => true
HTTP::Headers{"Foo" => "bar"} == HTTP::Headers{"foo" => "bar"} # => true
HTTP::Headers{"Foo" => "bar"} == HTTP::Headers{"Foo" => ["bar"]} # => true
HTTP::Headers{"Foo" => "bar"} == HTTP::Headers{"Foo" => "baz"} # => false
#dup
¶
Returns a shallow copy of this object.
Because Value is a value type, this method returns self,
which already involves a shallow copy of this object because
value types are passed by value.
#empty?
¶
Returns true if self is empty, false otherwise.
([] of Int32).empty? # => true
([1]).empty? # => false
#includes_word?(key, word)
¶
(key, word)
Returns if among the headers for key there is some that contains word as a value. The word is expected to match between word boundaries (i.e. non-alphanumeric chars).
require "http/headers"
headers = HTTP::Headers{"Connection" => "keep-alive, Upgrade"}
headers.includes_word?("Connection", "Upgrade") # => true
#inspect(io : IO) : Nil
¶
(io : IO) : Nil
Appends this struct's name and instance variables names and values to the given IO.
struct Point
def initialize(@x : Int32, @y : Int32)
end
end
p1 = Point.new 1, 2
p1.to_s # "Point(@x=1, @y=2)"
p1.inspect # "Point(@x=1, @y=2)"
