-DeviceCommons现已全面支持.NET依赖注入（Dependency Injection），提供了更灵活、可扩展和易于测试的架构。 - -## 快速开始 - -### 1. 基本注册 - -```csharp -using DeviceCommons; -using Microsoft.Extensions.DependencyInjection; -using Microsoft.Extensions.Hosting; - -// 在Startup.cs或Program.cs中注册服务 -services.AddDeviceCommons(); - -// 或在.NET 6+的Minimal API中 -var builder = WebApplication.CreateBuilder(args); -builder.Services.AddDeviceCommons(); -var app = builder.Build(); -``` - -### 2. 使用配置选项 - -```csharp -services.AddDeviceCommons(options => -{ - options.DefaultEncryptionPassword = "your-secure-password"; - options.EnableDefaultAesEncryption = true; -}); -``` - -### 3. 注入和使用 - -```csharp -public class DeviceService -{ - private readonly IDeviceMessageBuilder _builder; - private readonly IDeviceMessageSerializer _serializer; - private readonly IDeviceMessageParser _parser; - - public DeviceService( - IDeviceMessageBuilder builder, - IDeviceMessageSerializer serializer, - IDeviceMessageParser parser) - { - _builder = builder; - _serializer = serializer; - _parser = parser; -

.Build(); - - return _builder.BuildHex(); - } -} -``` - -## 高级配置 - -### 1. 自定义加密配置 - -#### 使用AES加密 -```csharp -services.AddDeviceCommons() - .WithAesEncryption("your-encryption-password"); -``` - -#### 使用自定义加密函数 -```csharp -services.AddDeviceCommons() - .WithCustomEncryption( - encryptFunc: plainText => YourCustomEncrypt(plainText), - decryptFunc: cipherText => YourCustomDecrypt(cipherText) - ); -``` - -### 2. 自定义状态工厂 - -#### 方式一：使用泛型注册 -```csharp -services.AddDeviceCommons() - .AddStateFactory(deviceType: 0x99); -``` - -#### 方式二：使用工厂方法 -```csharp -services.AddDeviceCommons(); -services.RegisterStateFactory(0x88, provider => new CustomStateFactory()); -``` - -#### 方式三：批量注册 -```csharp -services.AddDeviceCommons(); -services.RegisterStateFactories( - (deviceType: 0x01, typeof(TemperatureStateFactory), ServiceLifetime.Singleton), - (deviceType: 0x02, typeof(HumidityStateFactory), ServiceLifetime.Transient) -); -``` - -#### 方式四：使用构建器模式 -```csharp -services.AddDeviceCommons(); -services.ConfigureStateFactories(builder => -{ - builder.AddFactory(0x01); - builder.AddFactory(0x02); - builder.AddFactory(0x03, provider => new PressureStateFactory()); -}); -``` - -### 3. 自定义状态工厂实现 - -```csharp -public class CustomStateFactory : IStateFactory -{ -

-var message = builder - .WithHeader() - .WithMainDevice("DEVICE001", 0x01) - .Build(); - -// 静态工厂注册仍然有效 -StateFactoryRegistry.RegisterFactory(0x55, () => new CustomStateFactory()); -``` - -## ASP.NET Core 集成示例 - -### Program.cs (Minimal API) -```csharp -using DeviceCommons; - -var builder = WebApplication.CreateBuilder(args); - -// 注册DeviceCommons服务 -builder.Services.AddDeviceCommons(options => -{ - options.DefaultEncryptionPassword = builder.Configuration["DeviceCommons:EncryptionPassword"]; - options.EnableDefaultAesEncryption = true; -}); - -// 注册自定义状态工厂 -builder.Services.ConfigureStateFactories(factoryBuilder => -{ - factoryBuilder.AddFactory(0x01); - factoryBuilder.AddFactory(0x02); -}); - -// 注册应用服务 -builder.Services.AddScoped(); - -var app = builder.Build(); - -app.MapPost("/device/message", async (DeviceService service, DeviceRequest request) => -{ - var messageHex = await service.CreateDeviceMessageAsync(request); - return Results.Ok(new { Message = messageHex }); -}); - -app.Run(); -``` - -### 控制器示例 -```csharp -[ApiController] -[Route("api/[controller]")] -public class DeviceController : ControllerBase -{ - private readonly IDeviceMessageBuilder _builder;
