本文为大家分享了NancyFx框架检测任务管理器的具体方法，供大家参考，具体内容如下

先建一个空的项目和之前的NancyFx系列一样的步骤

然后建三个文件夹Models，Module，Views

然后分别安装一下组件

jQuery

Microsoft.AspNet.SignalR

Microsoft.Owin

Nancy

Nancy.Owin

然后往Model类里面添加CPUHub类，Broadcaster类

CPUHub类

public class CPUHub:Hub  {    private readonly Broadcaster broadcaster;    public CPUHub():this(Broadcaster.broadcaster)    {    }    public CPUHub(Broadcaster broadcaster)    {      this.broadcaster = broadcaster;    }  }

Broadcaster类

public class Broadcaster  {    private readonly static Lazy<Broadcaster> lazy = new Lazy<Broadcaster>(()=>new Broadcaster(GlobalHost.ConnectionManager.GetHubContext<CPUHub>().Clients));    private readonly TimeSpan timeSpan = TimeSpan.FromMilliseconds(1000);    private readonly Timer timer;    public static Broadcaster broadcaster    {      get { return lazy.Value; }    }    private IHubConnectionContext hubConnectionContext    {      get;      set;    }    private Broadcaster(IHubConnectionContext hubConnectionContexts)    {      hubConnectionContext = hubConnectionContexts;      timer = new Timer(BroadcastCpuUsage,null,timeSpan,timeSpan);    }    private void BroadcastCpuUsage(object o)    {      string cpu = GetCurrentCpu();    }    private string GetCurrentCpu()    {      string currentCpu = "";      HttpClient httpClient = new HttpClient();      httpClient.BaseAddress = new Uri("http://localhost:3039");      var response = httpClient.GetAsync("api/cpu").Result;      if (response.IsSuccessStatusCode)      {        currentCpu = response.Content.ReadAsStringAsync().Result;      }      return currentCpu;    }  }

然后在往Module里面添加CPUModule类

public class CPUModule:NancyModule  {    PerformanceCounter performanceCounter;    public CPUModule():base("api/cpu")    {      InitializePerformanceCounter();      Get("/",Lexan=>       {        int cpu = (int)Math.Ceiling(performanceCounter.NextValue());        return Response.AsText(cpu.ToString());      });    }    private void InitializePerformanceCounter()    {      performanceCounter = new PerformanceCounter();      performanceCounter.CategoryName = "";      performanceCounter.CounterName = "";      performanceCounter.InstanceName = "";      performanceCounter.NextValue();      Thread.Sleep(1000);    }  }

然后添加index.html页面在根目录下

<!DOCTYPE html><html><head>  <title>NancyTaskManager</title></head><body>  <label id="lblVal"></label>  <br />  <canvas id="cvPercentage"></canvas>  <br />  <br />  <canvas id="cvGraph" height="450" width="600"></canvas>  <script src="Scripts/jquery-2.1.0.js"></script>  <script src="Scripts/jquery.signalR-2.0.2.js"></script>  <script src="Scripts/Chart.js"></script>  <script src="/signalr/hubs"></script>  <script src="Scripts/taskManager.js"></script></body></html>

继续往根目录里面添加Startup类

[assembly:OwinStartup(typeof( NancyFxTaskManager.Startup))]namespace NancyFxTaskManager{  public class Startup  {    public void Configuration(IAppBuilder app)    {      app.MapSignalR().UseNancy();          }  }}
