c# networkcomms 3.0实现模拟登陆总结

最近项目需要做一个客户查询状态系统,当前上位机缺少服务功能,于是找到了networkcomms 开源框架,作为项目使用.

新建服务器端

namespace AppServer
{
    public partial class MaiForm : Form
    {
        public MaiForm()
        {
            InitializeComponent();
        }
        SendReceiveOptions aboveOptions = new SendReceiveOptions(DPSManager.GetDataSerializer<ProtobufSerializer>(), null, null);
        private void button1_Click(object sender, EventArgs e)
        {
            //服务器开始监听客户端的请求
            Connection.StartListening(ConnectionType.TCP, new IPEndPoint(IPAddress.Parse(txtIP.Text), int.Parse(txtPort.Text)));
            //服务器开始监听客户端的请求
            //IPEndPoint thePoint = new IPEndPoint(IPAddress.Parse(txtIP.Text), int.Parse(txtPort.Text));
            //TCPConnection.StartListening(thePoint, false);
            button1.Text = "监听中";
            button1.Enabled = false;
            //button1.Text = "监听中";
            //button1.Enabled = false;

            //此方法中包含服务器具体的处理方法。
            StartListening();
        }

        private void StartListening()
        {
            //开启日志记录
            //配置日志记录器
            //ILogger logger = new LiteLogger(LiteLogger.LogMode.ConsoleAndLogFile, "ServerLogFile_" + NetworkComms.NetworkIdentifier + ".txt");
            //NetworkComms.EnableLogging(logger);

            //禁用日志记录  服务器端正式使用时，赢禁用日志记录
            NetworkComms.DisableLogging();

            //服务器端处理收到的消息
            //为简单起见，此示例中我们只处理字符类型的信息，也返回字符类型的信息。
            //处理的信息可以使自定义类，具体见下一个Demo
            NetworkComms.AppendGlobalIncomingPacketHandler<LoginContract>("ReqLogin", IncomingLoginRequest);

        }
        //处理某个具体的请求
        private void IncomingLoginRequest(PacketHeader header, Connection connection, LoginContract loginContract)
        {
            try
            {
                string resMsg = "";

                //为了简单，这里不调用数据库，而是模拟一下登录
                if (loginContract.UserID == "" && loginContract.PassWord == "")

                    resMsg = "登录成功";

                else

                    resMsg = "用户名密码错误";
                //把返回结果写入到契约类中，后面返回给客户端
                //ResMsgContract contract = new ResMsgContract();
                //contract.Message = resMsg;

                //connection.SendObject<ResMsgContract>("ResLogin", contract);
                ResMsgContract contract = new ResMsgContract();
                contract.Message = resMsg;

                connection.SendObject("ResLogin", contract);
            }
            catch (Exception ex)
            {
                // LogTools.LogException(ex, "IncomingMsgHandle");
            }
        }
    }
}

在别的帮助中往往少了这行:导致出现客户端发送时,类型打包出现问题. 这行代码是客户端服务器两端都要加上的,是指定传输方式

 SendReceiveOptions aboveOptions = new SendReceiveOptions(DPSManager.GetDataSerializer<ProtobufSerializer>(), null, null);

就是这个报错了

一下是客户端

using MessageContract;
using NetworkCommsDotNet;
using NetworkCommsDotNet.Connections;
using NetworkCommsDotNet.Connections.TCP;
using NetworkCommsDotNet.DPSBase;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace AppClient
{
    public partial class MainForm : Form
    {
        public MainForm()
        {
            InitializeComponent();
        }
        //连接信息对象
        public ConnectionInfo connInfo = null;
        //连接对象
        Connection newTcpConnection;
        SendReceiveOptions aboveOptions = new SendReceiveOptions(DPSManager.GetDataSerializer<ProtobufSerializer>(), null, null);
        private void button1_Click(object sender, EventArgs e)
        {
            //给连接信息对象赋值
            connInfo = new ConnectionInfo(txtIP.Text, int.Parse(txtPort.Text));

            //如果不成功，会弹出异常信息
            newTcpConnection = TCPConnection.GetConnection(connInfo);

            button1.Enabled = false;
            button1.Text = "连接成功";
        }

        private void btnlogin_Click(object sender, EventArgs e)
        {
            //给契约类赋值
            LoginContract contract = new LoginContract(txtUserName.Text, txtPassword.Text);
            //contract.UserID = txtUserName.Text;
            //contract.PassWord = txtPassword.Text;
            //向服务器发送登录信息并获取登录结果
              ResMsgContract resMsg = newTcpConnection.SendReceiveObject<LoginContract, ResMsgContract>("ReqLogin", "ResLogin", , contract);
            //向服务器发送登录信息并获取登录结果
           // ResMsgContract resMsg = newTcpConnection.SendReceiveObject<ResMsgContract>("ReqLogin", "ResLogin", 5000, contract);

            if (resMsg.Message == "登录成功")
            {
                MessageBox.Show("登录成功");

            }
            else
            {
                MessageBox.Show("用户名密码错误");
            }
        }
    }
}

契约类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace MessageContract
{
    [ProtoContract]
    public class LoginContract
    {
        [ProtoMember()]
        public string UserID { get; set; }

        [ProtoMember()]
        public string PassWord { get; set; }

        public LoginContract() { }

        public LoginContract(string userID, string passWord)
        {
            this.UserID = userID;
            this.PassWord = passWord;
        }
    }
}

using ProtoBuf;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace MessageContract
{
    [ProtoContract]
    public  class ResMsgContract
    {
        [ProtoMember()]
        public string Message;
        public ResMsgContract() { }
        public ResMsgContract(string message)
        {
            this.Message = message;
        }
    }
}

注意:

使用这个框架要配合谷歌的protobuf   要选好版本.本人没重复测试最高版本,因为在调试登录过程中出现别的问题过程中,也顺改了protobuf 的版本,至今未测试最高版本是否存在兼容问题.本人成功的使用的是2.0.0.668

    protobuf简介protobuf是google提供的一个开源序列化框架,类似于XML,JSON这样的数据表示语言,其最大的特点是基于二进制,因此比传统的XML表示高效短小

vs nuget添加方式

输入

版本选择自己指定一下,加大项目的契约类里边.这是自己定义传输对象的方式.

结果:
