Ruby HTTP get with params

I know this post is old but for the sake of those brought here by google, there is an easier way to encode your parameters in a URL safe manner. I'm not sure why I haven't seen this elsewhere as the method is documented on the Net::HTTP page. I have seen the method described by Arsen7 as the accepted answer on several other questions also.

Mentioned in the Net::HTTP documentation is URI.encode_www_form(params):

# Lets say we have a path and params that look like this:path = "/search"params = {q: => "answer"}# Example 1: Replacing the #path_with_params method from Arsen7def path_with_params(path, params)   encoded_params = URI.encode_www_form(params)   [path, encoded_params].join("?")end# Example 2: A shortcut for the entire example by Arsen7uri = URI.parse("http://localhost.com" + path)uri.query = URI.encode_www_form(params)response = Net::HTTP.get_response(uri)

Which example you choose is very much dependent on your use case. In my current project I am using a method similar to the one recommended by Arsen7 along with the simpler #path_with_params method and without the block format.

# Simplified example implementation without response# decoding or error handling.require "net/http"require "uri"class Connection  VERB_MAP = {    :get    => Net::HTTP::Get,    :post   => Net::HTTP::Post,    :put    => Net::HTTP::Put,    :delete => Net::HTTP::Delete  }  API_ENDPOINT = "http://dev.random.com"  attr_reader :http  def initialize(endpoint = API_ENDPOINT)    uri = URI.parse(endpoint)    @http = Net::HTTP.new(uri.host, uri.port)  end  def request(method, path, params)    case method    when :get      full_path = path_with_params(path, params)      request = VERB_MAP[method].new(full_path)    else      request = VERB_MAP[method].new(path)      request.set_form_data(params)    end    http.request(request)  end  private  def path_with_params(path, params)    encoded_params = URI.encode_www_form(params)    [path, encoded_params].join("?")  endendcon = Connection.newcon.request(:post, "/account", {:email => "test@test.com"})=> #<Net::HTTPCreated 201 Created readbody=true> 

I assume that you understand the examples on the Net::HTTP documentation page but you do not know how to pass parameters to the GET request.

You just append the parameters to the requested address, in exactly the same way you type such address in the browser:

require 'net/http'res = Net::HTTP.start('localhost', 3000) do |http|  http.get('/users?id=1')endputs res.body

If you need some generic way to build the parameters string from a hash, you may create a helper like this:

require 'cgi'def path_with_params(page, params)  return page if params.empty?  page + "?" + params.map {|k,v| CGI.escape(k.to_s)+'='+CGI.escape(v.to_s) }.join("&")endpath_with_params("/users", :id => 1, :name => "John&Sons")# => "/users?name=John%26Sons&id=1"
