.net通过类组装数据转换为json并且传递给对方接口

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
{
    ///

    public string msg {get; set;}
    ///

    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(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:PLMLoggerDataDangAnData” + DateTime.Now.ToString(“yyyy-MM-dd”) + “.txt”, true);
        sw.WriteLine(LogStr);
    }
    catch
    {
    }
    finally
    {
        if (sw != null)
        {
            sw.Close();
        }
    }
}
