NancyFx框架检测任务管理器详解

时间：2021-05-20

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(); } }}

好了我们准备就绪，看看运行效果
