.normalize_param(key, value) ⇒ String

Returns This key value pair as a param

Examples:

normalize_param(:name, “Bob Jones”) #=> “name=Bob%20Jones&”

  normalized_keys = normalize_keys(key, value)

  normalized_keys.inject('') do |string, (k, v)|
    string + "#{k}=#{ERB::Util.url_encode(v.to_s)}&"
  end
end

.to_params(hash) ⇒ String

Returns This hash as a query string

Examples:

{ name: "Bob",
  address: {
    street: '111 Ruby Ave.',
    city: 'Ruby Central',
    phones: ['111-111-1111', '222-222-2222']
  }
}.to_params
  #=> "name=Bob&address[city]=Ruby Central&address[phones][]=111-111-1111&address[phones][]=222-222-2222&address[street]=111 Ruby Ave."
