MQTTnet AspNetCore AttributeRouting

This addon to MQTTnet provides the ability to define controllers and use attribute-based routing against message topics in a manner that is very similar to AspNet Core.

Features

Encapsulate your incoming message logic in controllers
Use familiar paradigms from AspNetCore in your MQTT logic
First-class support for dependency injection using existing ServiceProvider implementaiton in your AspNetCore project
Use together with any other MQTTnet options

Performance Note

This library has not been tested against a very high-load environment yet. Ensure you do your own load testing prior to use in production. All performance improvement PRs are welcome.

Supported frameworks

.NET Standard 2.0+
.NET Core 3.1+

Supported MQTT versions

5.0.0
3.1.1
3.1.0

Nuget

This library is available as a nuget package: https://www.nuget.org/packages/MQTTnet.AspNetCore.AttributeRouting/

Usage

Install this package and MQTTnet from nuget.

Modify your Startup.cs with the following options:

public void ConfigureServices(IServiceCollection services)
{
	// ... All your other configuration ...

	// Identify and build routes for the current assembly
	services.AddMqttControllers();

	services
		.AddHostedMqttServerWithServices(s =>
		{
			// Optionally set server options here
			s.WithoutDefaultEndpoint();

			// Enable Attribute routing
			s.WithAttributeRouting();
		})
		.AddMqttConnectionHandler()
		.AddConnections();
}

Create your controllers by inheriting from MqttBaseController and adding actions to it like so:

[MqttController]
[MqttRoute("[controller]")] // Optional route prefix
public class MqttWeatherForecastController : MqttBaseController
{
	private readonly ILogger<MqttWeatherForecastController> _logger;

	// Controllers have full support for dependency injection just like AspNetCore controllers
	public MqttWeatherForecastController(ILogger<MqttWeatherForecastController> logger)
	{
		_logger = logger;
	}

	// Supports template routing with typed constraints just like AspNetCore
	// Action routes compose together with the route prefix on the controller level
	[MqttRoute("{zipCode:int}/temperature")]
	public async Task WeatherReport(int zipCode)
	{
		// We have access to the MqttContext
		if (zipCode != 90210) { MqttContext.CloseConnection = true; }

		// We have access to the raw message
		var temperature = BitConverter.ToDouble(Message.Payload);

		_logger.LogInformation($"It's {temperature} degrees in Hollywood");

		if (temperature <= 0 && temperature >= 130)
		{
			// Example validation
			MqttContext.AcceptPublish = false;
		}
	}
}
