模拟http请求返回json数据的接口并解析

工作中用到，记录方便以后：

思路：http请求restful接口，返回json字符串，然后将字符串解析为对象。

1，先看看浏览器中请求返回的结果。

3，GetWebContent 方法代码：

        /// <summary>
        /// 用Get方式获取HTML页面内容
        /// </summary>
        /// <param name="url"></param>
        /// <param name="encode"></param>
        /// <returns></returns>
        public static string GetWebContent(string url, string encode)
        {
            string strResult = "";
            try
            {
                var request = (HttpWebRequest)WebRequest.Create(url);
                //声明一个HttpWebRequest请求   
                request.Timeout = 30000;
                //设置连接超时时间   
                request.Headers.Set("Pragma", "no-cache");
                var response = (HttpWebResponse)request.GetResponse();
                Stream streamReceive = response.GetResponseStream();
                Encoding encoding = Encoding.GetEncoding(string.IsNullOrEmpty(encode) ? "gb2312" : encode);
                if (streamReceive != null)
                {
                    var streamReader = new StreamReader(streamReceive, encoding);
                    strResult = streamReader.ReadToEnd();
                }
            }
            catch (Exception ex)
            {

            }
            return strResult;
        }
