POST - 向指定的资源提交要被处理的数据
1.什么是WebAPI,详见:http://www.cxyclub.cn/n/25123/
 /// <summary>
        /// 获取post过来的数据
        /// </summary>
        /// <returns>返回解析的参数和值</returns>
        [HttpPost]
        private string GetResponseVal()
        {
            SortedDictionary<object, object> sorted = new SortedDictionary<object, object>();
            var request = HttpContext.Current.Request;
            Stream resStream = request.InputStream;
            int len = (int)resStream.Length;//post数据长度
            string res = string.Empty;
            if (len != 0)
            {
                byte[] inputByts = new byte[len];//字节数据,用于存储post数据
                resStream.Read(inputByts, 0, len);//将post数据写入byte数组中s
                resStream.Close();
                res = Encoding.UTF8.GetString(inputByts);//转为UTF8编码
            }
            return res;
        }
