如何发送和接收原始JSON

本文关键字：原始 JSON 何发送 | 更新日期: 2023-09-27 18:26:43

我需要一些帮助来确定这个方向。我只需要程序在给定的IP和端口向服务器发送一个固定的原始简单JSON格式的消息，然后它需要在给定的端口上侦听响应，然后将原始响应写入控制台。

我发现了一些关于处理JSONhttp请求的主题，但我认为我没有走上正轨。这是我正在尝试调整的代码。

public static void send_json()
{
    HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://10.211.55.5:7752");
    request.ContentType = "application/json; charset=utf-8";
    request.Accept = "application/json";
    request.Method = "POST";
    using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))
    {
        writer.Write("{'"request'": '"get_menu'", '"checksum'": '"'", '"table_state'": {'"table_id'": '"1'", '"waiter_id'": '"1001'"}}");
    }
    WebResponse response = request.GetResponse();
    Stream stream = response.GetResponseStream();
    string json = "";
    using (StreamReader reader = new StreamReader(stream))
    {
        while (!reader.EndOfStream)
        {
            json += reader.ReadLine();
        }
        Console.Write(json);
    }
}

如何发送和接收原始JSON

下面的代码终于工作了！谢谢你们给我指明了正确的方向！

private void pos_test_button_Click(object sender, EventArgs e)
    {
        System.Net.Sockets.TcpClient clientSocket = new System.Net.Sockets.TcpClient();
        clientSocket.Connect("127.0.0.1", 7777);
        string get_menu_request = "{'"request'": '"get_menu'"}";
        NetworkStream serverStream = clientSocket.GetStream();
        byte[] outStream = System.Text.Encoding.ASCII.GetBytes(get_menu_request);
        serverStream.Write(outStream, 0, outStream.Length);
        serverStream.Flush();
        byte[] inStream = new byte[10025];
        serverStream.Read(inStream, 0, (int)clientSocket.ReceiveBufferSize);
        string _returndata = System.Text.Encoding.ASCII.GetString(inStream);
        test_log_box.AppendText("'r'n'r'nPOS Connection Test: " + "'r'n" + _returndata);
    }
