MQTTnet 的Asp.Net Core 认证事件的扩展

MQTTnet 的数据接收 连接 等事件都很丰富， 唯独客户端连接验证不能依赖注入也不能很舒服的使用事件的方式， 因此MQTTnet.AspNetCoreEx 就出现了。 
示例如下:
在  public void ConfigureServices(IServiceCollection services) 中加入 

  public void ConfigureServices(IServiceCollection services)

在    public void Configure(IApplicationBuilder app, IHostingEnvironment env）中加入:

   app.UseMqttServerEx(server =>
            {
                server.ClientConnectedHandler = new MqttServerClientConnectedHandlerDelegate(args => mqttEventsHandler.Server_ClientConnected(server, args));
            //ClientConnectionValidatorHandler 
                server.ClientConnectionValidatorHandler = new MqttServerClientConnectionValidatorHandlerDelegate(args => mqttEventsHandler.Server_ClientConnectionValidator(server, args));
            });
