SuperSocket 1.4系列文档(1) 第一个例子, EchoService

First example, EchoService

1. 新建一个名叫 “EchoService” 的空白项目
2. 添加SuperSocket的Common和SocketBase这两个dll或者项目引用到EchoService项目

3. 新增名为EchoServer和EchoSession的类，如下图

EchoSession.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using SuperSocket.SocketBase;

namespace SuperSocket.QuickStart.EchoService
{
    public class EchoSession : AppSession<EchoSession>
    {
        public override void StartSession()
        {
            SendResponse("Welcome to EchoServer!");
        }

        public override void HandleExceptionalError(Exception e)
        {
            SendResponse("Server side error occurred!");
        }
    }
}

EchoServer.cs

 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using SuperSocket.SocketBase;

namespace SuperSocket.QuickStart.EchoService
{
    public class EchoServer : AppServer<EchoSession>
    {

    }
}

4. 添加命令类

ECHO.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using SuperSocket.SocketBase.Command;

namespace SuperSocket.QuickStart.EchoService.Command
{
    public class ECHO : StringCommandBase<EchoSession>
    {
        #region CommandBase<EchoSession> Members

        public override void ExecuteCommand(EchoSession session, StringCommandInfo commandInfo)
        {
            session.SendResponse(commandInfo.Data);
        }

        #endregion
    }
}

注意: 命令类必须为public.

5. 编译项目 “EchoService” 然后拷贝项目输出到"SocketService"这个项目的输出目录 (请先提前编译SocketService项目)

6. 更新SocketService的配置文件app.config 来启用“EchoService”

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
        <section name="socketServer" type="SuperSocket.SocketEngine.Configuration.SocketServiceConfig, SuperSocket.SocketEngine"/>
    </configSections>
    <appSettings>
        <add key="ServiceName" value="EchoService"/>
    </appSettings>
    <socketServer loggingMode="IndependantFile">
        <servers>
            <server name="EchoServer"
                 serviceName="EchoService" ip="Any" port="911" mode="Async">
            </server>
        </servers>
        <services>
            <service name="EchoService"
                     type="SuperSocket.QuickStart.EchoService.EchoServer, SuperSocket.QuickStart.EchoService" />
        </services>
    </socketServer>
    <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0" />
    </startup>
</configuration>

请注意配置文件中的 "socketServer" 节点.

7. 运行“RunServer.bat” 然后输入任意键启动SuperSocket, 然后你就可以通过telnet client来测试你的EchoService了 (你也可以运行"InstallService.bat"来将SuperSocket安装成服务,  服务的名称是在app.config的appSetting以"ServiceName"为key的值，你可以按照项目需要修改它)，测试方式如下，输入“ECHO Any message”:
