Unity3D自学笔记——Photon服务器的后台架构实现（四）

ALI.ARPG.Domain
实现ICommand, ICommandHandler, IValidateHandler的一系列类

public class UserRegisterCommand : ICommand    {        public string Name;        public string Password;    }

public class UserRegisterHandler : ICommandHandler<UserRegisterCommand>    {        private readonly AccountRepository accountRepository;        private UnitOfWork unitOfWork;        public UserRegisterHandler()        {            unitOfWork = new UnitOfWork();            accountRepository = new AccountRepository(unitOfWork.Session);        }        public ICommandResult Excute(UserRegisterCommand command)        {        //这里用了AutoMapper，做了 Entity <-->ICommand之间的映射，AutoMapper的配置在Server层            AccountEntity account = Mapper.Map<AccountEntity>(command);            accountRepository.Add(account);            //通过unitOfWork将数据处理打包执行            unitOfWork.Commit();            return new CommandResult(true);        }    }

public IEnumerable<ValidationResult> Validate(UserRegisterCommand command)        {            //TODO 用户注册验证逻辑            //e.g.:            //if (string.IsNullOrEmpty(command.Name))            //{            //    yield return new ValidationResult("Name", "必须输入用户名");            //}            return null;        }

ALI.ARPG.Server

AutoMapper
配置，这里用的是AutoMapper5.0，稍微和前面的版本有些区别

public class AutoMapperConfiguration    {        public static void Configure()        {            Mapper.Initialize(x =>            {                x.AddProfile(new ViewModelToDomainMappingProfile());                x.AddProfile(new DomainToViewModelMappingProfile());            });        }    }

Entity -> Command

public class DomainToViewModelMappingProfile : Profile    {        public DomainToViewModelMappingProfile()        {            this.CreateMap<UserRegisterCommand, AccountEntity>();        }    }

Command -> Entity

public class ViewModelToDomainMappingProfile : Profile    {         public ViewModelToDomainMappingProfile()        {            this.CreateMap<AccountEntity, UserRegisterCommand>();        }    }

Application
Photon Server 的Host 类

public class Application : ApplicationBase    {        private static readonly ILogger log = ExitGames.Logging.LogManager.GetCurrentClassLogger();        protected override PeerBase CreatePeer(InitRequest initRequest)        {            return new AliPeer(initRequest.Protocol, initRequest.PhotonPeer);        }        protected override void Setup()        {            try {             //AutoMapper            AutoMapperConfiguration.Configure();            //Log            ExitGames.Logging.LogManager.SetLoggerFactory(Log4NetLoggerFactory.Instance);            GlobalContext.Properties["Photon:ApplicationLogPath"] = Path.Combine(this.ApplicationRootPath, "log");            GlobalContext.Properties["LogFileName"] = "ALI" + this.ApplicationName;            XmlConfigurator.ConfigureAndWatch(new FileInfo(Path.Combine(this.BinaryPath, "log4net.config")));            log.Debug("服务器启动成功");            }            catch(Exception ex)            {                log.Debug(ex.Message);            }        }        protected override void TearDown()        {            log.Debug("服务器关闭");        }    }

AliPeer
Photon Server 的Peer类，和客户端进行交互的类

public class AliPeer : PeerBase    {        private static readonly ILogger log = ExitGames.Logging.LogManager.GetCurrentClassLogger();        private ICommandBus commandBus;        public AliPeer(IRpcProtocol protocol, IPhotonPeer peer) : base(protocol, peer) {            commandBus = new CommandBus();        }        protected override void OnDisconnect(DisconnectReason reasonCode, string reasonDetail)        {        }        protected override void OnOperationRequest(OperationRequest operationRequest, SendParameters sendParameters)        {            if (AliPeer.log.IsDebugEnabled)            {                AliPeer.log.DebugFormat("OnOperationRequest. Code={0}", operationRequest.OperationCode);            }            //根据OpreationCode 去调度具体的方法            switch (operationRequest.OperationCode)            {                case (byte)OperationCode.Register:                    HandleRegisterOperation(operationRequest, sendParameters);                    break;                case (byte)OperationCode.Login:                    HandleLoginrOperation(operationRequest, sendParameters);                    break;                default:                    break;            }        }        protected virtual void HandleRegisterOperation(OperationRequest operationRequest, SendParameters sendParameters)        {        //获取客户端的消息，将Json转化为实体，用到LitJson.dll            object json;            operationRequest.Parameters.TryGetValue(operationRequest.OperationCode, out json);            AccountEntity account = JsonMapper.ToObject<AccountEntity>(json.ToString());            //AutoMapper, Entity -> Command            var command = Mapper.Map<AccountEntity, UserRegisterCommand>(account);            //通过CommandBus反射调用IValidateHandler, 执行消息验证            IEnumerable<ValidationResult> errors = commandBus.Validate(command);            OperationResponse response = new OperationResponse();            if(errors != null && errors.ToList().Count > 0)            {                response.ReturnCode = (short)ReturnCode.Error;            }            else            {                //通过CommandBus反射调用ICommandHandler, 执行Submit                var result = commandBus.Submit(command);                if (result.Success)                {                    response.ReturnCode = (short)ReturnCode.Sucess;                }                else                {                    response.ReturnCode = (short)ReturnCode.Faild;                }            }            //返回客户端处理结果            SendOperationResponse(response, sendParameters);        }        protected virtual void HandleLoginrOperation(OperationRequest operationRequest, SendParameters sendParameters)        {        }    }

OK 到此，服务端基本框架已完成，还可以加入AOP进行日志处理
