如何在 ruby 中处理 URL 以提取组成部分（方案、用户名、密码、主机等）？

我正在尝试使用 ruby （和 Net::SSH）创建一个程序来连接到服务器并执行一些任务。服务器的详细信息应以如下形式提供：

ssh://user:pass@host:port (for a host that does not yet have SSH keys)

或

user@host

Net::SSH 需要以下格式：

Net::SSH.start('host', 'user', :password => "password")

是否有 gem/stdlib 可以将 URL 处理为这种格式？或者一个可以匹配不同部分的简单正则表达式？

注意：我知道并使用 capistrano，但在这种情况下我需要较低级别的控制。

I'm trying create a program using ruby (and Net::SSH) to connect to servers and perform some tasks. The details of the server are to be provided as something like:

ssh://user:pass@host:port (for a host that does not yet have SSH keys)

user@host

Net::SSH expects the following format:

Net::SSH.start('host', 'user', :password => "password")

Is there are gem/stdlib that can process the URL into this format? Or a simple regex that can match the different parts?

Note: I'm aware of, and use, capistrano but in this case I need lower level control.

URI 和 Addressable::URI 可以解析 URL 并让您将它们分解为各个组件。

URI 包含在 Ruby 的标准库中，这很好，但是 Addressable::URI 有更多功能，当我必须对 URL 进行大量工作时，我会使用它。

require 'addressable/uri'

uri = Addressable::URI.parse('ssh://user:[email protected]:81') 
uri.host # => "www.example.com"
uri.user # => "user"
uri.password # => "pass"
uri.scheme # => "ssh"
uri.port # => 81

require 'uri'
uri = URI.parse('ssh://user:[email protected]:81')
uri.host # => "www.example.com"
uri.user # => "user"
uri.password # => "pass"
uri.scheme # => "ssh"
uri.port # => 81

Both URI and Addressable::URI can parse URLs and let you break them down into their components.

URI is included in Ruby's Standard Library, which is nice, but Addressable::URI has more features, and is what I use when I have to do a lot of work on URLs.

require 'addressable/uri'

uri = Addressable::URI.parse('ssh://user:[email protected]:81') 
uri.host # => "www.example.com"
uri.user # => "user"
uri.password # => "pass"
uri.scheme # => "ssh"
uri.port # => 81

require 'uri'
uri = URI.parse('ssh://user:[email protected]:81')
uri.host # => "www.example.com"
uri.user # => "user"
uri.password # => "pass"
uri.scheme # => "ssh"
uri.port # => 81
