SignalR
ASP.NET SignalR 是爲 ASP.NET 開發人員提供的一個庫,可以簡化開發人員將實時 Web 功能添加到應用程序的過程。實時 Web 功能是指這樣一種功能:當所連接的客戶端變得可用時服務器代碼可以立即向其推送內容,而不是讓服務器等待客戶端請求新的數據。
服務端:控制檯應用程序----可以看到客戶端連接掉線的消息,給那個客戶端發送了消息
客戶端:windows服務---通過命令註冊到windows服務裏開機自動啓動用到Topshelf、定時調度Quartz,同時客戶端又是一個服務端來給UDP客戶端發送消息。
本來想實現Quartz的job調度,但是這樣注入不到windows服務裏,最後還是選擇了用 System.Timers.Timer
客戶端實現如下:
1、新建控制檯程序起名叫SignalRClient
2、引入如下nuget包
Microsoft.AspNet.SignalR.Client
log4net
Quartz
Topshelf
3、普通的控制檯程序是無法注入到windows服務裏,必須用Topshelfc纔可以注入到windows服務裏,並且可以啓動停止。
注入的命令很簡單打開dos命令
4、客戶端代碼如下:
新建TopshelfService類
using Microsoft.AspNet.SignalR.Client;
using SignalRClient.Entity;
using System;
using System.Configuration;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading;
namespace SignalRClient
{
public class TopshelfService
{
private static Socket udpServer;
private static string _message = "";
static HubConnection connection = null;
static IHubProxy myHub = null;
static string url = ConfigurationManager.AppSettings.Get("url");
public void Start()
{
//服務邏輯
try
{
double time = double.Parse(ConfigurationManager.AppSettings["timeout"]);
System.Timers.Timer t = new System.Timers.Timer(time);//實例化Timer類,設置間隔時間爲10000毫秒;
t.Elapsed += new System.Timers.ElapsedEventHandler(theout);//到達時間的時候執行事件;
t.AutoReset = true;//設置是執行一次(false)還是一直執行(true);
t.Enabled = true;//是否執行System.Timers.Timer.Elapsed事件;
t.Start();
//以下是有開啓了一個socket當作服務端給本地socket發送消息
udpServer = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
//udpServer.Bind(new IPEndPoint(IPAddress.Parse("127.0.0.1"), 6678));//綁定端口號和IP
Console.WriteLine("socket服務端開啓成功!");
//Thread t1 = new Thread(ReciveMsg);//開啓接收消息線程
//t1.Start();
Thread t2 = new Thread(sendMsg);//開啓發送消息線程
t2.Start();
Console.ReadKey();
}
catch (Exception ex)
{
LogHelper.WriteLog(ex.Message.ToString(), ex);
}
}
public void Stop()
{
}
private static void theout(object source, System.Timers.ElapsedEventArgs e)
{
NewMethod();
}
/// <summary>
/// UDP服務端向特定ip的主機的端口發送數據報

static void sendMsg()
{
EndPoint point = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 6677);
while (true)
{
string msg = CommonMsg.Message;
if (!string.IsNullOrWhiteSpace(msg))
{
udpServer.SendTo(Encoding.UTF8.GetBytes(msg), point);
//_message = "";
}
}
}
/// <summary>
/// 一直等待服務端推送消息
/// </summary>
private static void NewMethod()
{
string clientName = ConfigurationManager.AppSettings.Get("clientName");
Console.WriteLine("客戶端: " + "設備id =》" + clientName + "開啓");
connection = new HubConnection(url, "clientName=" + clientName);
//類名必須與服務端一致
myHub = connection.CreateHubProxy("BroadcastHub");
//方法名必須與服務端一致
myHub.On<string>("ReceiveMsg", ReceiveMsg);
connection.Start().ContinueWith(task =>
{
if (!task.IsFaulted)
{
Console.WriteLine("與服務器連接成功");
}
else
{
Console.WriteLine("與服務器連接失敗,請確認服務器是否開啓!");
}
}).Wait();
}
/// <summary>
/// 從服務端接收到的消息
/// </summary>
/// <param name="message"></param>
private static void ReceiveMsg(string message)
{
CommonMsg.Message = message;
Console.WriteLine("來自服務器的消息:" + message);
}
/// <summary>
/// 接收發送給本機ip對應端口號的數據報
/// </summary>
static void ReciveMsg()
{
while (true)
{
EndPoint point = new IPEndPoint(IPAddress.Any, 0);//用來保存發送方的ip和端口號
byte[] buffer = new byte[1024];
int length = udpServer.ReceiveFrom(buffer, ref point);//接收數據報
string message = Encoding.UTF8.GetString(buffer, 0, length);
Console.WriteLine(point.ToString() + message);
}
}
}
}
新建一個公共接收消息類CommonMsg
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace SignalRClient.Entity
{
public class CommonMsg
{
public static string Message = "";
}
}
新建一個日誌幫助類LogHelper
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace SignalRClient
{
public class LogHelper
{
public static readonly log4net.ILog loginfo = log4net.LogManager.GetLogger("loginfo");
public static readonly log4net.ILog logerror = log4net.LogManager.GetLogger("logerror");
public static void WriteLog(string info)
{
if (loginfo.IsInfoEnabled)
{
loginfo.Info(info);
}
}
public static void WriteLog(string info, Exception ex)
{
if (logerror.IsErrorEnabled)
{
logerror.Error(info, ex);
}
}
}
}
新建一個日誌config文件
