Question

我试图摆脱带有空格的 URL, 然后对 Ruby 的 URL 进行请求。

我犯的错误是

/Users/user/.rvm/rubies/ruby-1.9.2-p290/lib/ruby/1.9.1/net/http.rb:393:in `get_response : undefined method `host  for "http://google.com/?this%20is%20a%20stromg%20with%20spaces":String (NoMethodError)
from test_url.rb:6:in `<main>

这是目前的代码

require  rubygems 
require  net/http 

uri = URI.escape("http://google.com/?this is a string with spaces")
res = Net::HTTP.get_response(uri)
puts res.body if res.is_a?(Net::HTTPSuccess) 

Net::HTTP.start(uri.host, uri.port) do |http|
  request = Net::HTTP::Get.new uri.request_uri

  response = http.request request # Net::HTTPResponse object
end

URI.esape 只是逃脱了它,别无其他。您需要实际的 URI 实例才能传递到 get_ response :

uri = URI.parse(URI.escape("http://google.com/?this is a string with spaces"))
