推荐答案

2019 年，URI.encode 已过时，不应使用.

In 2019, URI.encode is obsolete and should not be used.

require 'uri'

URI.encode("Hello there world")
#=> "Hello%20there%20world"
URI.encode("hello there: world, how are you")
#=> "hello%20there:%20world,%20how%20are%20you"

URI.decode("Hello%20there%20world")
#=> "Hello there world"
