Description

Addressable is a replacement for the URI implementation that is part of Ruby's standard library. It more closely conforms to the relevant RFCs and adds support for IRIs and URI templates. Additionally, it provides extensive support for URI templates.

Reference

• {Addressable::URI}
• {Addressable::Template}

Example usage

require "addressable/uri"

uri = Addressable::URI.parse("http://example.com/path/to/resource/")
uri.scheme
#=> "http"
uri.host
#=> "example.com"
uri.path
#=> "/path/to/resource/"

uri = Addressable::URI.parse("http://www.詹姆斯.com/")
uri.normalize
#=> #<Addressable::URI:0xc9a4c8 URI:http://www.xn--8ws00zhy3a.com/>

require "addressable/template"

template = Addressable::Template.new("http://example.com/{-list|+|query}/")
template.expand({
  "query" => "an example query".split(" ")
})
#=> #<Addressable::URI:0xc9d95c URI:http://example.com/an+example+query/>

template = Addressable::Template.new(
  "http://example.com/{-join|&|one,two,three}/"
)
template.partial_expand({"one" => "1", "three" => 3}).pattern
#=> "http://example.com/?one=1{-prefix|&two=|two}&three=3"

template = Addressable::Template.new(
  "http://{host}/{-suffix|/|segments}?{-join|&|one,two,bogus}\#{fragment}"
)
uri = Addressable::URI.parse(
  "http://example.com/a/b/c/?one=1&two=2#foo"
)
template.extract(uri)
#=>
# {
#   "host" => "example.com",
#   "segments" => ["a", "b", "c"],
#   "one" => "1",
#   "two" => "2",
#   "fragment" => "foo"
# }
