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
