.net从网络接口地址获取json，然后解析成对象（一）

整理代码，今天遇到一个问题，就是从一个场景接口获取json，然后解析成对象。之前的时候都好好的，这次返回的json字符串里，由于字符编码的问题，格式上不能转换。一直以为是解析的过程编码有误，试了utf-8，gb2312，Default、Unicode，发现都不行，转回头去找获取的时候字符编码，发现是gbk，那就了然了。果断统一改成utf-8之后，数据获取就正常了。

这段代码从获取到解析，还不是很熟练，所以把整个过程都捋一遍。

首先是根据网络地址和参数获取的方法：

 public static string CreateOrderList(string _tid, string _dateFrom, string _dateTo, string _state, int _page)
 {
     try
     {
         StringBuilder serviceUrl = new StringBuilder();
         serviceUrl.Append("http://10.10.10.10/queryOrderOne?");
         serviceUrl.AppendFormat("tid={0}&createDateFrom={1}&createDateTo={2}&pageNum={4}&pageSize=10&orderState={3}", _tid, _dateFrom, _dateTo, _state, _page);
         string _result = ExcuteGet(serviceUrl.ToString(),"");
         return _result;
 }
     catch (Exception e)
     {
         AddLog(_tid, "获取订单List异常：" + e.Message, "GetOrderList");
         return "";
     }
 }

ExcuteGet方法是获取地址的具体方法，代码如下：

 public static string ExcuteGet(string serviceUrl, string ReqInfo)
 {
     using (null)
     {
         ServicePointManager.ServerCertificateValidationCallback += ValidateServerCertificate;
         ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;
         ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls;
         HttpWebRequest request = (HttpWebRequest)WebRequest.Create(serviceUrl);
         request.CookieContainer = new CookieContainer();
         request.Headers.Add("userName", "test");  //设置信息头用户名
         request.Headers.Add("password", ""); //设置信息头密码
         request.KeepAlive = true;
         request.Method = "GET";
         request.ContentType = "application/x-www-form-urlencoded";
         //添加发送数据
         Encoding encoding = Encoding.GetEncoding("utf-8");
         if (!ReqInfo.Equals(""))
         {
             ReqInfo = "request=" + ReqInfo;
             byte[] postData = encoding.GetBytes(ReqInfo);
             request.ContentLength = postData.Length;
             Stream requestStream = request.GetRequestStream();
             requestStream.Write(postData, , postData.Length);
         }
         HttpWebResponse response = (HttpWebResponse)request.GetResponse();
         //获取返回数据
         Stream responseStream = response.GetResponseStream();
         if (responseStream == null) return "";
         StreamReader streamReader = new StreamReader(responseStream, encoding);
         string retString = streamReader.ReadToEnd();
         streamReader.Close();
         responseStream.Close();
         return retString;
     }
 }

还有一部分：

 private static bool ValidateServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
 {
     return true;
 }

之后就是解析了，方法如下：

 public static List<OrderList> GetOrderIList(string _dStrat, string _dEnd, string _tid, string _billState, int _page)
 {
     using (null)
     {
         try
         {
             string _jsonResult = CreateOrderList(_tid, _dStrat, _dEnd, _billState, _page);
             OrderList _addResult = _jsonResult.JsonTodeserialize<OrderList>(Encoding.GetEncoding("utf-8"));
             List<OrderList> _searchList = new List<OrderList>();
 　　　　　　　_searchList.Add(_addResult);
            return _searchList;
         }
         catch (Exception)
         {
             return new List<OrderList>();
         }
     }
 }

orderlist对象如下：

 public class OrderList
 {
     public List<resultList> resultList { get; set; }
     public string totalRecord { get; set; }
     public string totalPage { get; set; }
 }
 public class resultList
 {
     public string orderState { get; set; }
     public string Name { get; set; }
     public string orderNum { get; set; }
     public string productTypes { get; set; }
 }
