事件

MQTT 客户端

MQTTNet 服务器

ABP vNext 模块

PostgreSQL / Redis

后台处理作业

📦 三、依赖包准备

dotnet add package MQTTnet
dotnet add package Volo.Abp.BackgroundWorkers
dotnet add package Volo.Abp.EventBus

npm install -g mqtt-benchmark

🧪 四、动手实战：快速搭建 MQTT 服务

🧱 以下代码展示了如何注册和配置一个 ABP 模块内的 MQTT 服务器，以及消息验证和日志记录逻辑：

public class MqttModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
// 注册并配置 MQTT Server
context.Services
.AddMqttServer(options =>
{
options.WithDefaultEndpointPort(1883)
.WithEncryptedEndpointPort(8883)
.WithTlsEndpointCertificate("certs/server.pfx", "your_password")
.WithConnectionValidator(c =>
{
if (c.Username != "iot_user" || c.Password != "secure_password")
c.ReasonCode = MqttConnectReasonCode.BadUserNameOrPassword;
else
c.ReasonCode = MqttConnectReasonCode.Success;
})
.WithApplicationMessageInterceptor(c =>
{
var payload = Encoding.UTF8.GetString(c.ApplicationMessage.Payload);
var logger = c.Context.ServiceProvider.GetRequiredService<ILogger<MqttModule>>();
logger.LogInformation("收到消息: {Topic} – {Payload}", c.ApplicationMessage.Topic, payload);
});
})
.AddHostedMqttServerHostedService()
.AddSingleton<IApplicationMessageInterceptor, DeviceDataHandler>()
.AddSingleton<IDeviceDataRepository, DeviceDataRepository>()
.AddBackgroundWorker<DeviceDataWorker>();
}

public override void OnPostApplicationInitialization(ApplicationInitializationContext context)
{
var logger = context.ServiceProvider.GetRequiredService<ILogger<MqttModule>>();
logger.LogInformation("▶ MQTT Module 已初始化完毕，正在监听 1883/8883 端口");
}
}

🔄 五、ABP 模块事件交互

📢 ABP vNext 中本地事件用 ILocalEventBus，分布式用 IDistributedEventBus。

public class DeviceDataHandler : IApplicationMessageInterceptor
{
private readonly IDistributedEventBus _eventBus;
private readonly ILogger<DeviceDataHandler> _logger;

public DeviceDataHandler(IDistributedEventBus eventBus, ILogger<DeviceDataHandler> logger)
{
_eventBus = eventBus;
_logger = logger;
}

public Task InterceptApplicationMessagePublishAsync(ApplicationMessageInterceptorContext context)
{
var payload = Encoding.UTF8.GetString(context.ApplicationMessage.Payload);
try
{
var data = JsonSerializer.Deserialize<DeviceData>(payload);
if (data != null)
{
return _eventBus.PublishAsync(new DeviceDataReceivedEto
{
DeviceId = data.DeviceId,
Temperature = data.Temperature,
Timestamp = data.Timestamp
});
}
_logger.LogWarning("无效负载: {Payload}", payload);
}
catch (Exception ex)
{
_logger.LogError(ex, "处理 MQTT 负载时出错: {Payload}", payload);
}
return Task.CompletedTask;
}
}

⚡ 六、性能优化建议

🧪 延迟 P95/P99：用于评估峰值响应；Inflight 控制对延迟尤为关键。

⚙️ 压测命令示例：

mqtt-benchmark -broker tcp://localhost:1883 -num-clients 1000 -num-messages 100000 -qos 1 –report results.csv

🔐 七、安全增强建议

builder.WithEncryptedEndpoint()
.WithEncryptedEndpointPort(8883)
.WithTlsEndpointCertificate("path/to/cert.pfx", "password");

• 👤 设置用户名/密码验证和 TLS 加密
• 🔑 接入 JWT 鉴权与 Topic 白名单控制
• 🛡️ IP 白名单与连接速率限制
• 🧾 使用 ABP 权限系统进行订阅权限校验
• 📜 启用连接日志与审计日志

ABP JWT 配置片段（appsettings.json）：

"Authentication": {
"JwtBearer": {
"Authority": "https://your-auth-server",
"RequireHttpsMetadata": true
}
}

✅ 八、总结

• 🛰️ MQTT 是构建 IoT 系统通信的高效协议
• 🏗️ ABP vNext 提供了完备的模块化与扩展支持
• 🧱 配置消息中间件与权限系统可提升系统鲁棒性
