游戏战斗服务器

实现一个高扩展、高性能、高可配置的C#版游戏战斗服务器是一个复杂的任务，涉及多个方面的设计和实现。以下是一个详细的实现示例，涵盖了玩家管理、战斗逻辑、网络通信、并发处理、日志记录等方面。

1. 项目结构

首先，我们定义项目的结构：

GameServer ├── Controllers │   ├── BattleController.cs │   └── PlayerController.cs ├── Models │   ├── Player.cs │   ├── Battle.cs │   └── BattleResult.cs ├── Services │   ├── PlayerService.cs │   ├── BattleService.cs │   └── AuthService.cs ├── Utils │   ├── Logger.cs │   └── Config.cs ├── Program.cs └── Startup.cs 

2. 依赖项

我们需要以下依赖项：

• ASP.NET Core
• Entity Framework Core
• Serilog
• JWT (JSON Web Token)
• AutoMapper

3. 配置文件

在appsettings.json中配置数据库连接字符串和JWT密钥：

{   "ConnectionStrings": {     "DefaultConnection": "Server=localhost;Database=GameServer;User Id=sa;Password=your_password;"   },   "Jwt": {     "Key": "your_secret_key",     "Issuer": "your_issuer",     "Audience": "your_audience"   },   "Serilog": {     "MinimumLevel": {       "Default": "Information",       "Override": {         "Microsoft": "Warning",         "System": "Warning"       }     },     "WriteTo": [       { "Name": "Console" },       { "Name": "File", "Args": { "path": "Logs/log.txt", "rollingInterval": "Day" } }     ]   } } 

4. 数据模型

4.1 Player.cs

namespace GameServer.Models {     public class Player     {         public int Id { get; set; }         public string Username { get; set; }         public int Level { get; set; }         public int Health { get; set; }         public int Attack { get; set; }         public int Defense { get; set; }     } } 

4.2 Battle.cs

namespace GameServer.Models {     public class Battle     {         public int Id { get; set; }         public int Player1Id { get; set; }         public int Player2Id { get; set; }         public DateTime StartTime { get; set; }         public DateTime EndTime { get; set; }         public BattleResult Result { get; set; }     } } 

4.3 BattleResult.cs

namespace GameServer.Models {     public enum BattleResult     {         Player1Win,         Player2Win,         Draw     } }

using GameServer.Models; using Microsoft.EntityFrameworkCore; using System; using System.Collections.Concurrent; using System.Threading.Tasks;  namespace GameServer.Services {     public class BattleService     {         private readonly GameDbContext _dbContext;         private readonly PlayerService _playerService;         private readonly ConcurrentQueue<Func<Task>> _battleQueue = new ConcurrentQueue<Func<Task>>();          public BattleService(GameDbContext dbContext, PlayerService playerService)         {             _dbContext = dbContext;             _playerService = playerService;         }          public async Task<Battle> StartBattleAsync(int player1Id, int player2Id)         {             var player1 = await _playerService.GetPlayerAsync(player1Id);             var player2 = await _playerService.GetPlayerAsync(player2Id);              if (player1 == null || player2 == null)             {                 throw new Exception("Player not found");             }              var battle = new Battle             {                 Player1Id = player1Id,                 Player2Id = player2Id,                 StartTime = DateTime.UtcNow             };              _dbContext.Battles.Add(battle);             await _dbContext.SaveChangesAsync();              return battle;         }          public async Task<BattleResult> ExecuteBattleAsync(int battleId)         {             var tcs = new TaskCompletionSource<BattleResult>();             _battleQueue.Enqueue(async () =>             {                 var battle = await _dbContext.Battles.FindAsync(battleId);                 if (battle == null)                 {                     tcs.SetException(new Exception("Battle not found"));                     return;                 }                  var player1 = await _playerService.GetPlayerAsync(battle.Player1Id);                 var player2 = await _playerService.GetPlayerAsync(battle.Player2Id);                  if (player1 == null || player2 == null)                 {                     tcs.SetException(new Exception("Player not found"));                     return;                 }                  var result = SimulateBattle(player1, player2);                  battle.EndTime = DateTime.UtcNow;                 battle.Result = result;                  _dbContext.Battles.Update(battle);                 await _dbContext.SaveChangesAsync();                  tcs.SetResult(result);             });              await ProcessQueueAsync();             return await tcs.Task;         }          private async Task ProcessQueueAsync()         {             while (_battleQueue.TryDequeue(out var battleTask))             {                 await battleTask();             }         }          private BattleResult SimulateBattle(Player player1, Player player2)         {             // 简单的战斗模拟逻辑             var player1Power = player1.Attack - player2.Defense;             var player2Power = player2.Attack - player1.Defense;              if (player1Power > player2Power)             {                 return BattleResult.Player1Win;             }             else if (player2Power > player1Power)             {                 return BattleResult.Player2Win;             }             else             {                 return BattleResult.Draw;             }         }     } } 

12. 配置管理

我们可以使用配置文件来管理游戏参数，例如战斗参数、玩家属性等。

12.1 appsettings.json

{   "GameSettings": {     "DefaultPlayerHealth": 100,     "DefaultPlayerAttack": 10,     "DefaultPlayerDefense": 5   } } 

12.2 Config.cs

using Microsoft.Extensions.Configuration;  namespace GameServer.Utils {     public class Config     {         private readonly IConfiguration _configuration;          public Config(IConfiguration configuration)         {             _configuration = configuration;         }          public int DefaultPlayerHealth => _configuration.GetValue<int>("GameSettings:DefaultPlayerHealth");         public int DefaultPlayerAttack => _configuration.GetValue<int>("GameSettings:DefaultPlayerAttack");         public int DefaultPlayerDefense => _configuration.GetValue<int>("GameSettings:DefaultPlayerDefense");     } } 

13. 日志记录

我们可以增强日志记录，便于调试和监控。

13.1 Logger.cs

using Serilog;  namespace GameServer.Utils {     public static class Logger     {         public static void LogInformation(string message)         {             Log.Information(message);         }          public static void LogWarning(string message)         {             Log.Warning(message);         }          public static void LogError(string message)         {             Log.Error(message);         }     } } 

13.2 BattleService.cs

using GameServer.Models; using GameServer.Utils; using Microsoft.EntityFrameworkCore; using System; using System.Collections.Concurrent; using System.Threading.Tasks;  namespace GameServer.Services {     public class BattleService     {         private readonly GameDbContext _dbContext;         private readonly PlayerService _playerService;         private readonly ConcurrentQueue<Func<Task>> _battleQueue = new ConcurrentQueue<Func<Task>>();          public BattleService(GameDbContext dbContext, PlayerService playerService)         {             _dbContext = dbContext;             _playerService = playerService;         }          public async Task<Battle> StartBattleAsync(int player1Id, int player2Id)         {             var player1 = await _playerService.GetPlayerAsync(player1Id);             var player2 = await _playerService.GetPlayerAsync(player2Id);              if (player1 == null || player2 == null)             {                 Logger.LogError("Player not found");                 throw new Exception("Player not found");             }              var battle = new Battle             {                 Player1Id = player1Id,                 Player2Id = player2Id,                 StartTime = DateTime.UtcNow             };              _dbContext.Battles.Add(battle);             await _dbContext.SaveChangesAsync();              Logger.LogInformation($"Battle started between Player {player1Id} and Player {player2Id}");              return battle;         }          public async Task<BattleResult> ExecuteBattleAsync(int battleId)         {             var tcs = new TaskCompletionSource<BattleResult>();             _battleQueue.Enqueue(async () =>             {                 var battle = await _dbContext.Battles.FindAsync(battleId);                 if (battle == null)                 {                     Logger.LogError("Battle not found");                     tcs.SetException(new Exception("Battle not found"));                     return;                 }                  var player1 = await _playerService.GetPlayerAsync(battle.Player1Id);                 var player2 = await _playerService.GetPlayerAsync(battle.Player2Id);                  if (player1 == null || player2 == null)                 {                     Logger.LogError("Player not found");                     tcs.SetException(new Exception("Player not found"));                     return;                 }                  var result = SimulateBattle(player1, player2);                  battle.EndTime = DateTime.UtcNow;                 battle.Result = result;                  _dbContext.Battles.Update(battle);                 await _dbContext.SaveChangesAsync();                  Logger.LogInformation($"Battle {battleId} ended with result: {result}");                  tcs.SetResult(result);             });              await ProcessQueueAsync();             return await tcs.Task;         }          private async Task ProcessQueueAsync()         {             while (_battleQueue.TryDequeue(out var battleTask))             {                 await battleTask();             }         }          private BattleResult SimulateBattle(Player player1, Player player2)         {             // 简单的战斗模拟逻辑             var player1Power = player1.Attack - player2.Defense;             var player2Power = player2.Attack - player1.Defense;              if (player1Power > player2Power)             {                 return BattleResult.Player1Win;             }             else if (player2Power > player1Power)             {                 return BattleResult.Player2Win;             }             else             {                 return BattleResult.Draw;             }         }     } } 

14. 结论

通过添加缓存机制、并发处理、配置管理和增强日志记录，我们进一步优化了游戏战斗服务器的性能和可扩展性。这些改进使得服务器能够更高效地处理玩家请求，并且更容易进行调试和监控。

希望这些内容能帮助你更好地理解和实现一个高扩展、高性能、高可配置的游戏战斗服务器。如果你有任何问题或需要进一步的帮助，请随时提问。

好的，我们可以继续扩展和优化游戏战斗服务器。接下来，我们将添加以下功能：

1. 身份验证和授权：确保只有经过身份验证的用户才能访问服务器资源。
2. 错误处理和异常管理：增强错误处理机制，确保系统的稳定性和可靠性。
3. 单元测试和集成测试：确保代码的正确性和稳定性。
4. 性能监控和分析：使用工具监控和分析服务器性能。

15. 身份验证和授权

我们可以使用JWT（JSON Web Token）来实现身份验证和授权。

15.1 安装必要的NuGet包

dotnet add package Microsoft.AspNetCore.Authentication.JwtBearer dotnet add package Microsoft.IdentityModel.Tokens 

15.2 配置JWT身份验证

在Startup.cs中配置JWT身份验证。

using Microsoft.AspNetCore.Authentication.JwtBearer; using Microsoft.IdentityModel.Tokens; using System.Text;  public class Startup {     public void ConfigureServices(IServiceCollection services)     {         services.AddControllers();          var key = Encoding.ASCII.GetBytes("YourSecretKeyHere");         services.AddAuthentication(x =>         {             x.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;             x.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;         })         .AddJwtBearer(x =>         {             x.RequireHttpsMetadata = false;             x.SaveToken = true;             x.TokenValidationParameters = new TokenValidationParameters             {                 ValidateIssuerSigningKey = true,                 IssuerSigningKey = new SymmetricSecurityKey(key),                 ValidateIssuer = false,                 ValidateAudience = false             };         });          services.AddAuthorization();     }      public void Configure(IApplicationBuilder app, IWebHostEnvironment env)     {         if (env.IsDevelopment())         {             app.UseDeveloperExceptionPage();         }          app.UseRouting();          app.UseAuthentication();         app.UseAuthorization();          app.UseEndpoints(endpoints =>         {             endpoints.MapControllers();         });     } } 

15.3 创建身份验证控制器

创建一个控制器来处理用户登录和生成JWT。

using Microsoft.AspNetCore.Mvc; using Microsoft.IdentityModel.Tokens; using System; using System.IdentityModel.Tokens.Jwt; using System.Security.Claims; using System.Text;  namespace GameServer.Controllers {     [ApiController]     [Route("api/[controller]")]     public class AuthController : ControllerBase     {         [HttpPost("login")]         public IActionResult Login([FromBody] LoginModel model)         {             // 这里应该验证用户的用户名和密码             if (model.Username == "test" && model.Password == "password")             {                 var tokenHandler = new JwtSecurityTokenHandler();                 var key = Encoding.ASCII.GetBytes("YourSecretKeyHere");                 var tokenDescriptor = new SecurityTokenDescriptor                 {                     Subject = new ClaimsIdentity(new Claim[]                     {                         new Claim(ClaimTypes.Name, model.Username)                     }),                     Expires = DateTime.UtcNow.AddHours(1),                     SigningCredentials = new SigningCredentials(new SymmetricSecurityKey(key), SecurityAlgorithms.HmacSha256Signature)                 };                 var token = tokenHandler.CreateToken(tokenDescriptor);                 var tokenString = tokenHandler.WriteToken(token);                  return Ok(new { Token = tokenString });             }              return Unauthorized();         }     }      public class LoginModel     {         public string Username { get; set; }         public string Password { get; set; }     } } 

15.4 保护控制器

在需要保护的控制器上添加[Authorize]属性。

using Microsoft.AspNetCore.Authorization; using Microsoft.AspNetCore.Mvc;  namespace GameServer.Controllers {     [Authorize]     [ApiController]     [Route("api/[controller]")]     public class PlayerController : ControllerBase     {         private readonly PlayerService _playerService;          public PlayerController(PlayerService playerService)         {             _playerService = playerService;         }          [HttpGet("{id}")]         public async Task<IActionResult> GetPlayer(int id)         {             var player = await _playerService.GetPlayerAsync(id);             if (player == null)             {                 return NotFound();             }             return Ok(player);         }          // 其他方法...     } } 

16. 错误处理和异常管理

我们可以使用全局异常处理来捕获和处理所有未处理的异常。

16.1 创建异常处理中间件

using Microsoft.AspNetCore.Http; using Serilog; using System; using System.Net; using System.Threading.Tasks;  namespace GameServer.Middleware {     public class ExceptionMiddleware     {         private readonly RequestDelegate _next;          public ExceptionMiddleware(RequestDelegate next)         {             _next = next;         }          public async Task InvokeAsync(HttpContext httpContext)         {             try             {                 await _next(httpContext);             }             catch (Exception ex)             {                 Log.Error($"Something went wrong: {ex}");                 await HandleExceptionAsync(httpContext, ex);             }         }          private Task HandleExceptionAsync(HttpContext context, Exception exception)         {             context.Response.ContentType = "application/json";             context.Response.StatusCode = (int)HttpStatusCode.InternalServerError;              return context.Response.WriteAsync(new ErrorDetails()             {                 StatusCode = context.Response.StatusCode,                 Message = "Internal Server Error from the custom middleware."             }.ToString());         }     }      public class ErrorDetails     {         public int StatusCode { get; set; }         public string Message { get; set; }          public override string ToString()         {             return Newtonsoft.Json.JsonConvert.SerializeObject(this);         }     } } 

16.2 注册中间件

在Startup.cs中注册异常处理中间件。

public void Configure(IApplicationBuilder app, IWebHostEnvironment env) {     if (env.IsDevelopment())     {         app.UseDeveloperExceptionPage();     }     else     {         app.UseMiddleware<ExceptionMiddleware>();     }      app.UseRouting();      app.UseAuthentication();     app.UseAuthorization();      app.UseEndpoints(endpoints =>     {         endpoints.MapControllers();     }); } 

17. 单元测试和集成测试

我们可以使用xUnit和Moq来编写单元测试和集成测试。

17.1 安装必要的NuGet包

dotnet add package xunit dotnet add package Moq dotnet add package Microsoft.AspNetCore.Mvc.Testing 

17.2 编写单元测试

创建一个测试项目，并编写单元测试。

using GameServer.Controllers; using GameServer.Models; using GameServer.Services; using Moq; using System.Threading.Tasks; using Xunit;  public class PlayerControllerTests {     [Fact]     public async Task GetPlayer_ReturnsPlayer_WhenPlayerExists()     {         // Arrange         var mockService = new Mock<PlayerService>(null, null);         mockService.Setup(service => service.GetPlayerAsync(1)).ReturnsAsync(new Player { Id = 1, Name = "TestPlayer" });          var controller = new PlayerController(mockService.Object);          // Act         var result = await controller.GetPlayer(1);          // Assert         var okResult = Assert.IsType<OkObjectResult>(result);         var player = Assert.IsType<Player>(okResult.Value);         Assert.Equal(1, player.Id);         Assert.Equal("TestPlayer", player.Name);     }      // 其他测试... } 

18. 性能监控和分析

我们可以使用Application Insights或其他性能监控工具来监控和分析服务器性能。

18.1 安装Application Insights

dotnet add package Microsoft.ApplicationInsights.AspNetCore 

18.2 配置Application Insights

在Startup.cs中配置Application Insights。

public void ConfigureServices(IServiceCollection services) {     services.AddControllers();     services.AddApplicationInsightsTelemetry(Configuration["ApplicationInsights:InstrumentationKey"]); } 

18.3 使用Application Insights

在代码中使用Application Insights记录自定义事件和指标。

using Microsoft.ApplicationInsights;  public class BattleService {     private readonly TelemetryClient _telemetryClient;      public BattleService(TelemetryClient telemetryClient)     {         _telemetryClient = telemetryClient;     }      public async Task<BattleResult> ExecuteBattleAsync(int battleId)     {         _telemetryClient.TrackEvent("BattleStarted", new Dictionary<string, string> { { "BattleId", battleId.ToString() } });          // 其他代码...          _telemetryClient.TrackEvent("BattleEnded", new Dictionary<string, string> { { "BattleId", battleId.ToString() } });          return result;     } } 

19. 结论

通过添加身份验证和授权、错误处理和异常管理、单元测试和集成测试以及性能监控和分析，我们进一步增强了游戏战斗服务器的安全性、稳定性和可维护性。这些改进使得服务器能够更好地应对各种挑战，并且更容易进行调试和优化。
