录播教室预约系统(五)-用户登陆

客户端登陆界面如下：

客户端代码：

Program.cs 中

                   //在全局处理函数中忽略相关消息 不添加日志
                   NetworkComms.IgnoreUnknownPacketTypes = true;

                    ConnectionInfo connInfo = new ConnectionInfo("127.0.0.1", 2539);
                 
          

                    Connection newTcpConnection = TCPConnection.GetConnection(connInfo);


                    //连接服务器完成******************************************

                    //初始化主窗口
                    MainForm mainForm = new MainForm();

                    //显示登录窗口
                    frmLogin loginForm = new frmLogin(applicationName, mainForm, newTcpConnection);

                   
                    //根据登陆窗口返回的信息，打开主窗口，或者是注册窗口
                    if (loginForm.ShowDialog() == DialogResult.OK)
                    {
                        if(loginForm.Register == 5)
                        { 

                        Application.Run(mainForm);

                        }
                        else
                        {

                          Register newRegister = new Register();

                          newRegister.Initialize(newTcpConnection);

                          Application.Run(newRegister);

                        }

                     }

登陆窗口中的登陆按钮相关代码

private void btnLogin_Click(object sender, EventArgs e)
        {
            // 如果通过输入验证
            if (UserInputCheck())
            {
                try
                {

                    bool isPass = false;

                    Users theUser = new Users();

                    theUser.UserID = txtLoginName.Text.Trim();
                    theUser.Password = txtUserPwd.Text.Trim(); 
                   //发送当前登陆用户的信息给服务器，并从服务器获取返回的信息
                    LoginResult loginResult = newTcpConnection.SendReceiveObject<LoginResult>("Login", "LoginResult", 5000, theUser);
                     

                    if (loginResult.Message=="登录成功")
                    {
                        //记录用户名


                        netConfiguration.UserID = theUser.UserID;

                        netConfiguration.Save();

                        //初始化主窗口中的属性

                        theUser.Department = loginResult.Department;
                        theUser.Name = loginResult.UserName;
                         
                        mainForm.InitiaLize(this.newTcpConnection, theUser);

                       
                        // 标识验证通过
                        isPass = true;
                        Register = 5;
                        this.DialogResult = DialogResult.OK;
                    }

                    // 如果未通过验证
                    if (!isPass)
                    {
                        
                        MessageBox.Show(loginResult.Message);
                    }
                }
                catch (Exception ex)
                {
                    ShowLoginLostToolTip(ex);
                }
            }
        }

Users实体类，支持Protobuf.net序列化

服务器端程序的处理代码：

 

在服务器端构造函数中声明针对登陆操作的处理器：

//用户验证处理器

            NetworkComms.AppendGlobalIncomingPacketHandler<Users>("Login", HandleUserVerify);

//用户登录验证
