.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", "123456"); //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, 0, 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; }
}
