Parametrized get request in Ruby?

Question

How do I make an HTTP GET request with parameters in Ruby?

It's easy to do when you're POSTing:

  require 'net/http'   require 'uri'    HTTP.post_form URI.parse('http://www.example.com/search.cgi'),                  { "q" => "ruby", "max" => "50" } 

But I see no way of passing GET parameters as a hash using 'net/http'.

Answer 1

Since version 1.9.2 (I think) you can actually pass the parameters as a hash to the URI::encode_www_form method like this:

require 'uri'  uri = URI.parse('http://www.example.com/search.cgi') params = { :q => "ruby", :max => "50" }  # Add params to URI uri.query = URI.encode_www_form( params ) 

and then fetch the result, depending on your preference

require 'open-uri'  puts uri.open.read 

or

require 'net/http'  puts Net::HTTP.get(uri) 

Answer 2

Use the following method:

require 'net/http' require 'cgi'  def http_get(domain,path,params)     return Net::HTTP.get(domain, "#{path}?".concat(params.collect { |k,v| "#{k}=#{CGI::escape(v.to_s)}" }.join('&'))) if not params.nil?     return Net::HTTP.get(domain, path) end  params = {:q => "ruby", :max => 50} print http_get("www.example.com", "/search.cgi", params)
