调用带参数的网络连接返回对象的两种方法

第一种，这种方法对汉字进行了加密，会出现乱码，但解析之后就是正常汉字了。

代码如下

StringBuilder serviceUrl = new StringBuilder();

serviceUrl.Append("http://xxx/queryOrderOne?");

serviceUrl.AppendFormat("id={0}", _id);

string _result = ExcuteGet1(serviceUrl.ToString(),"");

ExcuteGet1方法代码

public static string ExcuteGet1(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", "lvkang");  //设置信息头用户名
        request.Headers.Add("password", "12345"); //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("GBK");

        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;
    }
}

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

这种方法就是返回的result里的中文是乱码，但是使用json的转换之后又好了，原理不是很理解。

OrderList _addResult = _jsonResult.JsonTodeserialize(Encoding.Default);

public static T JsonTodeserialize(this string json, Encoding _encoding)
        {
            using (null)
            {
                try
                {
                    DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(T));
                    T obj = default(T);
                    using (MemoryStream ms = new MemoryStream(_encoding.GetBytes(json)))
                    {
                        obj = (T)serializer.ReadObject(ms);
                        ms.Close();
                    }
                    return obj;
                }
                catch (Exception)
                {
                    return default(T);
                }
            }
        }

解析的方法如上。

第二种，简单

ExcuteGet2方法代码

public static string ExcuteGet2(string url)
        {
            var request = (HttpWebRequest)WebRequest.Create(url);
            var response = (HttpWebResponse)request.GetResponse();
            return new StreamReader(response.GetResponseStream()).ReadToEnd();
        }

解析结果用的方法是

JsonConvert.DeserializeObject(_result)

用的是Newtonsoft.Json.dll里的一个方法。

Order和OrderList均是我自己构建的类。
