Hash and Array in rails params：
https://rails.lighthouseapp.com/projects/8994/tickets/127-params-hash-is-incorrect-for-nested-arrays

<!-- first contact, 2 telephones -->
<input name="contact[][name]" ... />
<input name="contact[][telephone][][area_code]" ... />
<input name="contact[][telephone][][number]" ... />
<input name="contact[][telephone][][area_code]" ... />
<input name="contact[][telephone][][number]" ... />

等价下面：

{ "contact" => [
    { "name" => "nnn",
      "telephone" => [
        { "area_code" => "nnn", "number" => "nnn" },
        { "area_code" => "nnn", "number" => "nnn" }
      ]
    }
  ]
}

>> Hash[ *"a=1&b=2&c=3".split(/[=&]/)]
=> {"a"=>"1", "b"=>"2", "c"=>"3"}

original = Hash[*query_string.split(/[=&]/)]["original_uri"]
    URI.decode(original)
