给Httparty这个gem写的一个hack补丁

Httparty是一个很好用的基于Ruby的net库的gem，自身非常小巧，用法很灵活。
但是他有个毛病，就是发送完http请求之后返回的是http小的html部分，而不是消息头，比如set-cookie,status code,location等。

为了满足需求，又要保持Httparty源代码和官方同步，下面写了这个补丁：


"httpartyHack.rb"

# 
# To change this template, choose Tools | Templates
# and open the template in the editor.
module HttpartyHack
  
  def self.included(base)
    
    class << base
      alias_method :_send_request,:send_request
      include HackMethods
      #private_class_method :send_request
      private :send_request
    end

  end
  
end

module HackMethods
  
  def self.included(base)
    #p "HackMethods been #{base} included"
  end
  def send_request(method, path, options={}) #:nodoc:
    raise ArgumentError, 'only get, post, put and delete methods are supported' unless %w[get post put delete].include?(method.to_s)
    raise ArgumentError, ':headers must be a hash' if options[:headers] && !options[:headers].is_a?(Hash)
    raise ArgumentError, ':basic_auth must be a hash' if options[:basic_auth] && !options[:basic_auth].is_a?(Hash)
    uri= URI.parse("#{base_uri}#{path}")
    existing_query = uri.query ? "#{uri.query}&" : ''
    uri.query= if options[:query].blank?
      existing_query + default_params.to_query
    else
      existing_query + (options[:query].is_a?(Hash) ? default_params.merge(options[:query]).to_query : options[:query])
    end
    klass = Net::HTTP.const_get method.to_s.downcase.capitalize
    request  = klass.new(uri.request_uri)
    request.body= options[:body].is_a?(Hash) ? options[:body].to_query : options[:body] unless options[:body].blank?
    basic_auth  = options.delete(:basic_auth) || @auth
    request.initialize_http_header headers.merge(options[:headers] || {})
    # note to self: self, do not put basic auth above headers because it removes basic auth
    request.basic_auth(basic_auth[:username], basic_auth[:password]) if basic_auth
    response = http(uri).request(request)
    class<<response
      attr :header
    end
    response
  end

end

使用Httparty的时候需要:

include Httparty

如果你需要这个补丁的话，请在include Httparty之后：

include HttpartyHack

此时通过Httparty的get或者post方法得到的便是完整的response，而且该response增加了一个header方法，可以通过header方法访问该response的头，类型为Hash。
