在一个步骤中解析URI对象，并从中获取响应

Posted 2021-02-27

URI objects can be opened directly by open-uri

require "open-uri"
 
uri="http://www.ruby-lang.org/en/"
 
html=URI.parse(uri).read # string representation is the response body
 
http_headers=URI.parse(uri).read.meta # this hash's keys are also accessible as OpenURI instance methods, e.g. html.content_type
