小小练习：测试获取用户信息接口

简单分享一下，是如何对淘宝的用户信息如何获取！Util类，是封装的 TOP请求签名、组装普通文本、TOP API POST 请求，这可以在08或10编辑器下运行，

主要是有MD5加密，还有HttpWebRequest类的一些方法、属性，在WP7环境下，不完全支持！

public class Util

        /// <returns>签名</returns>

        {

            IEnumerator<KeyValuePair<string, string>> dem = sortedParams.GetEnumerator();
            StringBuilder query = new StringBuilder(secret);
            while (dem.MoveNext())
            {

                string value = dem.Current.Value;
                if (!string.IsNullOrEmpty(key) && !string.IsNullOrEmpty(value))
                {

                }

            MD5 md5 = MD5.Create();
            byte[] bytes = md5.ComputeHash(Encoding.UTF8.GetBytes(query.ToString()));
            StringBuilder result = new StringBuilder();
            for (int i = 0; i < bytes.Length; i++)
            {
                string hex = bytes[i].ToString("X");

控制台下Progrom中，调用上面的类，传入对应的参数，有单用户API和多用户请求的API，返回对应的XML！对于多用户解注释！：

//这是你申请开放合作伙伴的appKey和appSecret
string appKey = "test";
string appSecret = "test";
//他用类型且是获取私有数据的需要传递 sessionkey(对于公共数据，不许授权的数据可以为空，但隐私信息，需要session,如，用户个人的生日、是否绑定阿里账号。。。)
string session = "";
//这是淘宝API接口
string method = null;
//这是请求的环境，现在测试，用沙箱环境
//沙箱地址：http://gw.api.tbsandbox.com/router/rest
//正式地址：http://gw.api.taobao.com/router/rest
string url = "http://gw.api.tbsandbox.com/router/rest";

            #region taobao.user.get 单用户信息获取
            method = "taobao.user.get";
            IDictionary<string, string> param = new Dictionary<string, string>();

            param.Add("fields", "user_id,uid,nick,location");
            param.Add("nick", "alipublic01");
            string xml = Util.Post(url, appKey, appSecret, method, session, param);
            Console.Write("结果：" + xml);
            #endregion

            #region taobao.users.get 多用户信息获取
            //method = "taobao.users.get";
            //IDictionary<string, string> param = new Dictionary<string, string>();
            //param.Add("fields", "user_id,uid,nick,buyer_credit,seller_credit,type,sex,promoted_type,alipay_account,alipay_no,avatar");
            //param.Add("fields", "user_id,uid,nick,buyer_credit,location");
            //param.Add("nicks", "alipublic01,sandbox_c_1");
            //string xml = Util.Post(url, appKey, appSecret, method, session, param);
            //Console.Write("结果：" + xml);
            #endregion

这是单用户请求返回结果：
