.net通过类组装数据转换为json并且传递给对方接口

本文主要是介绍.net通过类组装数据转换为json并且传递给对方接口，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1、根据传递字段创建一个类

public class User

{

public string code{ get; set; }

public string name{ get; set; }

public string? email{ get; set; }

public string? address{ get; set; }

}

2、根据对方返回字段创建一个类

public class Result
{
/// <summary>
/// 数据接收成功
/// </summary>
public string msg { get; set; }
/// <summary>
///
/// </summary>
public string code { get; set; }
}

3、组装数据并且转换为json传递给某个接口

private void TransferToJson（）

{

User user= new User();

user.code="zhangsan";

user.name="张三";

user.email="12334567890@163.com";

user.address="上海市静安区";

//转换为json串

string json = "[" + JsonConvert.SerializeObject(user) + "]";

string url="对方的接口地址";

HttpWebRequest req = GetWebRequest(url, "POST", null);
req.Headers.Add(HttpRequestHeader.AcceptCharset, "utf-8");
req.ContentType = "application/json";

byte[] postData = Encoding.UTF8.GetBytes(json);
Stream reqStream = req.GetRequestStream();
reqStream.Write(postData, 0, postData.Length);
reqStream.Close();

HttpWebResponse rsp = (HttpWebResponse)req.GetResponse();
var code = string.IsNullOrEmpty(rsp.CharacterSet) || "ISO-8859-1".Equals(rsp.CharacterSet, StringComparison.CurrentCultureIgnoreCase) ? "UTF-8" : rsp.CharacterSet;
Encoding encoding = Encoding.GetEncoding(code);
string response = GetResponseAsString(rsp, encoding);

Result rs = JsonConvert.DeserializeObject<Result>(response);
//对方返回的结果
if (rs.code == "200")
{

//记录到日志
Log(rs.msg + ":" + json);
}
else
{
throw new System.Exception(rs.msg);
}

}

4、日志函数

private void Log(string LogStr)
{
//Trace.WriteLine(LogStr);
//return;
StreamWriter sw = null;
try
{
LogStr = DateTime.Now.ToLocalTime().ToString() + "\n" + LogStr;
sw = new StreamWriter("C:\\PLMLoggerData\\DangAnData" + DateTime.Now.ToString("yyyy-MM-dd") + ".txt", true);
sw.WriteLine(LogStr);
}
catch
{
}
finally
{
if (sw != null)
{
sw.Close();
}
}
}
