改了一下淘宝api demo..

改了一下淘宝api domo
改前:

#此DEMO的功能：查询手机类的淘客商品
require 'digest/md5'
require 'net/http'
require 'open-uri'
require 'iconv'

#获得当前时间
t = Time.new();

#组装参数
paramArray = {
	#组装协议参数
  	'app_key'=>'test',
  	'method'=>'taobao.taobaoke.items.get',
  	'format'=>'xml',
  	'v'=>'1.0',
  	'timestamp'=>t.strftime("%Y-%m-%d %H:%M:%S"),
  	#组装应用参数
  	'fields'=>'iid,title,nick,pic_url,price,click_url',
  	'pid' => 'mm_5410_0_0',
  	'cid' => '1512',
  	'page_no' => '1',
  	'page_size' => '6'
}

#生成签名
def sign(param,sercetCode)
	array = param.sort()
  	i = 0
  	str = sercetCode
  	while i < param.length()
    	temp = array[i]
      	str = str + temp[0] + temp[1]
      	i = i + 1    
  	end
  	str = Digest::MD5.hexdigest(str)
  	return str.upcase()
end

#组装请求参数
def createRequestParam(paramArray)
	array = paramArray.sort()
  	i = 0
  	str = ''
  	while i < paramArray.length()
    	temp = array[i]
    	str = str + temp[0] + '=' + temp[1] + '&'
    	i = i + 1    
  	end
  	return str
end

#URL encode
def URLEncode(str)
	return str.gsub!(/[^\w$&\-+.,\/:;=?@]/) { |x| x = format("%%%x", x[0])}  
end

#把str的编码转化为GBK编码
def to_gbk(str)
	Iconv.iconv("GBK//IGNORE","UTF-8//IGNORE",str).to_s
end
	url = 'http://gw.sandbox.taobao.com/router/rest?'
	url = url + createRequestParam(paramArray)+'sign=' + sign(paramArray,'test')
	parsedURL = URI.parse(URLEncode(url))

	#请求生成的URL，把结果输出
	Net::HTTP.version_1_2
	open(parsedURL)do|http|
    puts to_gbk(http.read)
end

My code:

require'md5'

require'cgi'

require'open-uri'

params = {
               'app_key'    => 'test',
               'method'      => 'taobao.taobaoke.items.get',
               'format'      => 'xml',
               'v'              => '1.0',
               'timestamp' => Time.now.strftime("%Y-%m-%d %H:%M:%S"),
               'fields'      => 'iid,title,nick,pic_url,price,click_url',
               'pid'           => 'mm_5410_0_0',
               'cid'           => '1512',
               'page_no'    => '1',
               'page_size' => '6'}

def sign(params,secret_code)
  Digest::MD5.hexdigest(params.sort.flatten.unshift(secret_code).join).upcase
end

def create_request_params params
  params.map{|key,value| "#{key}=#{CGI.escape(value)}"}.join("&")
end

url = 'http://gw.sandbox.taobao.com/router/rest?'

url = url + create_request_params(params.merge('sign' =>sign(params,'test')))

open(url) do |resp|
  p resp.read
end
