Args

String

Description

Public setter for the host component v (with validation).

See also URI::Generic.check_host.

Usage

require 'uri'

uri = URI.parse("http://my.example.com")
uri.host = "foo.com"
uri.to_s  #=> "http://foo.com"

Extract the host part of the URI and unwrap brackets for IPv6 addresses.

This method is the same as URI::Generic#host except brackets for IPv6 (and future IP) addresses are removed.

uri = URI("http://[::1]/bar")
uri.hostname      #=> "::1"
uri.host          #=> "[::1]"

Sets the host part of the URI as the argument with brackets for IPv6 addresses.

This method is the same as URI::Generic#host= except the argument can be a bare IPv6 address.

uri = URI("http://foo/bar")
uri.hostname = "::1"
uri.to_s  #=> "http://[::1]/bar"

If the argument seems to be an IPv6 address, it is wrapped with brackets.
