WindowsService使用SuperWebSocket
日期:2019-03-22 点击:3307 来源:PB2.CN
SuperWebSocket在WebService中的应用
1. 新建Windows服务项目【TestWindowsService】，重命名Service1为MyWebSocketService
2. 打开MyWebSocketService设计视图，右键，添加安装程序，自动添加ProjectInstaller.cs。
打开设计视图，选中ServiceInstaller1，右键修改属性：
ServiceName（服务名）:这里改为我们刚重命名的MyWebSocketService
StartType（启动方式）:改为自动启动Automatic
DelayedAutoStart（延迟加载）
选中serviceProcessInstaller1，右键修改属性：
Account（账户类型）：这里改为LocalSystem
3. 添加安装和卸载文件。注意添加文件请使用ANSI编码。推荐使用EditPlus等工具新建文件，然后通过项目添加现有项。
注意替换TestWindowsService.exe和MyWebSocketService。右键属性，设置复制到输出目录。
Install.bat:
%SystemRoot%\Microsoft.NET\Framework\v4.0.30319\installutil.exe TestWindowsService.exe sc config MyWebSocketService start= auto Net Start MyWebSocketService pause
Uninstall.bat
%SystemRoot%\Microsoft.NET\Framework\v4.0.30319\installutil.exe /u TestWindowsService.exe
4. 添加App.config，配置IP和Port。
IP地址为本地连接地址，端口号自定义。确保端口号不被占用。
<configuration> <startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" /> </startup> <appSettings> <add key="APWebSocketIP" value="192.168.1.199"/> <add key="APWebSocketPort" value="8200"/> </appSettings> </configuration>
5. 修改MyWebSocketService服务代码。
推荐手动加载dll，通过Nuget加载时，添加依赖的Log4net版本与SuperWebSocket中调用的Log4net版本存在冲突。
log4net版本为1.2.11.0
项目右键，管理Nuget程序包，搜索SuperWebSocket。
WebSocketServer server;
protected override void OnStart(string[] args)
{
var ip = ConfigurationManager.AppSettings["APWebSocketIP"];
var port = ConfigurationManager.AppSettings["APWebSocketPort"];
//WebSocket服务器端启动
server = new WebSocketServer();
if (!server.Setup(ip, int.Parse(port)))
{
//Debug.Write("WebSocket服务器端启动失败");
//处理启动失败消息
return;
}
//新的会话连接时
server.NewSessionConnected += server_NewSessionConnected;
//会话关闭
server.SessionClosed += server_SessionClosed;
//接收到新的消息时
server.NewMessageReceived += server_NewMessageReceived;
if (!server.Start())
{
//Debug.Write(string.Format("开启WebSocket服务侦听失败:{0}:{1}", server.Config.Ip, server.Config.Port));
//处理监听失败消息
return;
}
}
string KSessionId;
string VSessionId;
Dictionary<string, List<string>> msgDictionary = new Dictionary<string, List<string>>();
private void server_NewMessageReceived(WebSocketSession session, string value)
{
Debug.WriteLine("接收到新的消息：{0} 来自：{1} 时间:{2:HH:MM:ss}", value, session.RemoteEndPoint, DateTime.Now);
if (value.StartsWith("K"))
{
KSessionId = session.SessionID;
//页面已链接
if (!String.IsNullOrEmpty(VSessionId))
SendMsgToRemotePoint(VSessionId, string.Format("考场发来消息：{0}", value));
//页面未链接
else
{
AddMsgToSessionId(VSessionId);
}
}
else if (value.StartsWith("S"))
{
VSessionId = session.SessionID;
//考场已链接
if (!String.IsNullOrEmpty(KSessionId))
SendMsgToRemotePoint(KSessionId, string.Format("学生A发来消息：{0}", value));
//考场已断开
else
{
AddMsgToSessionId(KSessionId);
}
}
}
/// <summary>
/// 添加会话消息
/// </summary>
/// <param name="value"></param>
private void AddMsgToSessionId(string value)
{
if (value != null)
{
//消息列表包含页面会话ID
if (msgDictionary.ContainsKey(value))
{
msgDictionary[value].Add(value);
}
//消息列表不包含页面会话ID
else
msgDictionary.Add(value, new List<string>() { value });
}
}
/// <summary>
/// 会话关闭
/// </summary>
/// <param name="session"></param>
/// <param name="value"></param>
private void server_SessionClosed(WebSocketSession session, SuperSocket.SocketBase.CloseReason value)
{
Debug.WriteLine("会话关闭，关闭原因：{0} 来自：{1} 时间:{2:HH:MM:ss}", value, session.RemoteEndPoint, DateTime.Now);
if (session.SessionID == KSessionId)
SendMsgToRemotePoint(VSessionId, "考场已断开");
else if (session.SessionID == VSessionId)
SendMsgToRemotePoint(KSessionId, "学生A已断开");
}
/// <summary>
/// 新的会话链接
/// </summary>
/// <param name="session"></param>
private void server_NewSessionConnected(WebSocketSession session)
{
Debug.WriteLine("新的会话连接 来自：{0} SessionID:{1} 时间:{2:HH:MM:ss}", session.RemoteEndPoint, session.SessionID, DateTime.Now);
if (msgDictionary.ContainsKey(session.SessionID))
msgDictionary[session.SessionID].ForEach(item => session.Send(item));
}
/// <summary>
/// 发送消息到
/// </summary>
/// <param name="sessionId"></param>
/// <param name="msg"></param>
private void SendMsgToRemotePoint(string sessionId, string msg)
{
var allSession = server.GetAppSessionByID(sessionId);
if (allSession != null)
allSession.Send(msg);
}6.添加log4net配置文件log4net.config。查看日志。
由于SuperWebSocket已经有日志功能，只需要添加配置文件，即可查看日志。
<?xml version="1.0" encoding="utf-8" ?><log4net> <appender name="errorAppender" type="log4net.Appender.RollingFileAppender"> <filter type="log4net.Filter.LevelMatchFilter"> <levelToMatch value="ERROR" /> </filter> <filter type="log4net.Filter.DenyAllFilter" /> <File value="Logs\err.log" /> <appendToFile value="true" /> <rollingStyle value="Date" /> <datePattern value="yyyyMMdd" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" /> </layout> </appender> <appender name="infoAppender" type="log4net.Appender.RollingFileAppender"> <filter type="log4net.Filter.LevelMatchFilter"> <levelToMatch value="INFO" /> </filter> <filter type="log4net.Filter.DenyAllFilter" /> <File value="Logs\info.log" /> <appendToFile value="true" /> <rollingStyle value="Date" /> <datePattern value="yyyyMMdd" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" /> </layout> </appender> <appender name="debugAppender" type="log4net.Appender.RollingFileAppender"> <filter type="log4net.Filter.LevelMatchFilter"> <levelToMatch value="DEBUG" /> </filter> <filter type="log4net.Filter.DenyAllFilter" /> <File value="Logs\debug.log" /> <appendToFile value="true" /> <rollingStyle value="Date" /> <datePattern value="yyyyMMdd" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" /> </layout> </appender> <appender name="perfAppender" type="log4net.Appender.RollingFileAppender"> <filter type="log4net.Filter.LevelMatchFilter"> <levelToMatch value="INFO" /> </filter> <filter type="log4net.Filter.DenyAllFilter" /> <File value="Logs\perf.log" /> <appendToFile value="true" /> <rollingStyle value="Date" /> <datePattern value="yyyyMMdd" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date %logger - %message%newline" /> </layout> </appender> <root> <level value="ALL" /> <appender-ref ref="errorAppender" /> <appender-ref ref="infoAppender" /> <appender-ref ref="debugAppender" /> </root> <logger name="Performance" additivity="false"> <level value="ALL" /> <appender-ref ref="perfAppender" /> </logger></log4net>
在html中使用WebSocket
1、首先考虑浏览器兼容问题。一些低版本浏览器不支持。
2、创建websocket对象，设置ip和端口。
var ws;
var url = "ws://192.168.1.199:8200";
$("#btnConnection").click(function () {
if ("WebSocket" in window) {
ws = new WebSocket(url);
}
else if ("MozWebSocket" in window) {
ws = new MozWebSocket(url);
}
else
alert("浏览器版本过低，请升级您的浏览器。\r\n浏览器要求：IE10+/Chrome14+/FireFox7+/Opera11+");
//注册各类回调
ws.onopen = function () {
$("#msg").append("连接服务器成功<br/>");
ws.send("S:学生A已链接");
}
ws.onclose = function () {
$("#msg").append("与服务器断开连接<br/>");
}
ws.onerror = function () {
$("#msg").append("数据传输发生错误<br/>");
}
ws.onmessage = function (receiveMsg) {
$("#msg").append(receiveMsg.data + "<br/>");
}
});这篇文档对您是否有帮助？
