# MqttNet.DependencyInjection
基于MqttNet进行的服务封装中间件
## Mqtt服务配置
### 添加服务配置
首先在 Startup.cs文件进行配置：
```cs
public void ConfigureServices(IServiceCollection services)
{
//......
services.AddMqttClient(options => {
options.Server = "127.0.0.1"; //Mqtt服务器ip
options.Port = 60005; //端口
options.UserName = ""; //用户名
options.Passowrd = ""; //密码
options.ClientId = "ClientId"; //配置ClientId
}).AddEventHandler() //Topic配置和消息处理 handler类，
//开启心跳
.WithHeartBeat(options =>
{
options.EnableHeartBeat = true; //启用
options.PubHeartBeatTopic = "Clould/HeartBeat"; //发送心跳的Topic
options.HeartBeatinterval = TimeSpan.FromSeconds(1); //时间间隔
options.DeviceNo = "deviceNo"; //设备Id
options.CustmData = new{}; //自定义数据，心跳自动携带
})
//开启动态订阅和退订
.WithDynamicScribe(options =>
{
options.EnableDynamicSubcribe = true; //启用
options.SubcribeHeartBeatTopic = "Clould/HeartBeat"; //接收心跳的Topic
options.DynamicSubcribeinterval = TimeSpan.FromSeconds(1); //时间间隔
});
}
```
### 处理类编写
需要继承 AbsractClientHandler 抽象类
```cs
public class MqttClientEventHandler : AbsractClientHandler
{
public MqttClientEventHandler(IMqttPublisher mqttPublisher) : base(mqttPublisher)
{
}
//设置需要订阅的Topic列表，
//未开启动态订阅，将遍历所有主题全部订阅
//开启动态订阅，通过心跳解析，对其对应的ClientId下的Topic列表进行订阅和退订
public override void SetTopic(out List mqttClient)
{
mqttClient = new List()
{
new ClientTopic(){
DeviceNo = "deviceNo",
TopicList = new List
{
"topic1",
"topic2"
}
}
};
}
//心跳处理方法
public override void HeartBeatReceived(HeartBeatArgs args)
{
}
//消息处理方法，
public override void MessageReceived(MessageReceiveArgs args)
{
_mqttPublisher.PublishAsync(); //内置的发送信息服务
Console.WriteLine("### 收到来自服务器端的消息 ###");
// 收到的消息主题
string topic = args.Topic;
// 收到的的消息内容
string payload = args.Message;
// 收到的发送级别(Qos)
var qos = args.QosLevel;
// 收到的消息保持形式
bool retain = args.Retain;
args.AcknowledgeAsync(new CancellationTokenSource().Token);
var message = $"主题: [{topic}] 内容: [{payload}] Qos: [{qos}] Retain:[{retain}]";
Console.WriteLine(message);
}
}
```
### 发送消息
通过依赖注入获取发送信息接口服务
```cs
public class WeatherForecastController : ControllerBase
{
private static readonly string[] Summaries = new[]
{
"Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"
};
private readonly ILogger _logger;
private readonly IMqttPublisher _mqttPublisher;
public WeatherForecastController(ILogger logger,IMqttPublisher mqttPublisher)
{
_logger = logger;
_mqttPublisher = mqttPublisher; //依赖注入赋值对象
}
[HttpGet]
public IEnumerable Get()
{
_mqttPublisher.PublishAsync("topic","message"); //调用发送信息方法
var rng = new Random();
return Enumerable.Range(1, 5).Select(index => new WeatherForecast
{
Date = DateTime.Now.AddDays(index),
TemperatureC = rng.Next(-20, 55),
Summary = Summaries[rng.Next(Summaries.Length)]
})
.ToArray();
}
}
```
