# File lib/httparty/hash_conversions.rb, line 28 def self.normalize_param(key, value) normalized_keys = normalize_keys(key, value) normalized_keys.flatten.each_slice(2).inject(''.dup) do |string, (k, v)| string << "#{ERB::Util.url_encode(k)}=#{ERB::Util.url_encode(v.to_s)}&" end end
@param key<Object> The key for the param. @param value<Object> The value for the param.
@return <String> This key value pair as a param
@example normalize_param
(:name, “Bob Jones”) #=> “name=Bob%20Jones&”

@return <String> This hash as a query string
@example
{ 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."
