Overview
FastSocket是一个轻量级易扩展的c#异步socket通信库，项目开始于2011年，经过近3年不断调整与改进，目前在功能和性能上均有不错的表现。
项目地址:https://github.com/devhong/FastSocket.Net
FastSocket内置了命令行、二进制、thrift协议，基于此开发了Zookeeper, Redis, Thrift等c#异步客户端，接下来将会一一公开。
Requirements
.Net 4.0 or Mono 2.6
Example Usage
简单的命令行服务
新建控制台项目，添加FastSocket.SocketBase,FastSocket.Server引用
自定义服务实现MyService
using System;
using Sodao.FastSocket.Server;
using Sodao.FastSocket.Server.Command;
using Sodao.FastSocket.SocketBase; /// <summary>
/// 实现自定义服务
/// </summary>
public class MyService : CommandSocketService<StringCommandInfo>
{
/// <summary>
/// 当连接时会调用此方法
/// </summary>
/// <param name="connection"></param>
public override void OnConnected(IConnection connection)
{
base.OnConnected(connection);
Console.WriteLine(connection.RemoteEndPoint.ToString() + " connected");
connection.BeginSend(PacketBuilder.ToCommandLine("welcome"));
}
/// <summary>
/// 当连接断开时会调用此方法
/// </summary>
/// <param name="connection"></param>
/// <param name="ex"></param>
public override void OnDisconnected(IConnection connection, Exception ex)
{
base.OnDisconnected(connection, ex);
Console.ForegroundColor = ConsoleColor.Red;
Console.WriteLine(connection.RemoteEndPoint.ToString() + " disconnected");
Console.ForegroundColor = ConsoleColor.Gray;
}
/// <summary>
/// 当发生错误时会调用此方法
/// </summary>
/// <param name="connection"></param>
/// <param name="ex"></param>
public override void OnException(IConnection connection, Exception ex)
{
base.OnException(connection, ex);
Console.WriteLine("error: " + ex.ToString());
}
/// <summary>
/// 处理未知命令
/// </summary>
/// <param name="connection"></param>
/// <param name="commandInfo"></param>
protected override void HandleUnKnowCommand(IConnection connection, StringCommandInfo commandInfo)
{
commandInfo.Reply(connection, "unknow command:" + commandInfo.CmdName);
}
}
Exit命令
/// <summary>
/// 退出命令
/// </summary>
public sealed class ExitCommand : ICommand<StringCommandInfo>
{
/// <summary>
/// 返回命令名称
/// </summary>
public string Name
{
get { return "exit"; }
}
/// <summary>
/// 执行命令
/// </summary>
/// <param name="connection"></param>
/// <param name="commandInfo"></param>
public void ExecuteCommand(IConnection connection, StringCommandInfo commandInfo)
{
connection.BeginDisconnect();//断开连接
}
}
App.config配置
<?xml version="1.0"?>
<configuration> <configSections>
<section name="socketServer"
type="Sodao.FastSocket.Server.Config.SocketServerConfig, FastSocket.Server"/>
</configSections> <socketServer>
<servers>
<server name="cmdline"
port="8400"
socketBufferSize="8192"
messageBufferSize="8192"
maxMessageSize="102400"
maxConnections="20000"
serviceType="CommandLine.MyService, CommandLine"
protocol="commandLine"/>
</servers>
</socketServer> </configuration>
初始化及启动服务
static void Main(string[] args)
{
SocketServerManager.Init();
SocketServerManager.Start(); Console.ReadLine();
}
启动服务，然后在cmd中运行telnet 127.0.0.1 8400, 运行截图如下：
其中welcome中当连接建立时服务端发送到终端的。
connection.BeginSend(PacketBuilder.ToCommandLine("welcome"));
unknow command:Hello是因为没有对应的"Hello"命令实现由HandleUnKnowCommand输出的
/// <summary>
/// 处理未知命令
/// </summary>
/// <param name="connection"></param>
/// <param name="commandInfo"></param>
protected override void HandleUnKnowCommand(IConnection connection, StringCommandInfo commandInfo)
{
commandInfo.Reply(connection, "unknow command:" + commandInfo.CmdName);
}
当在终端中键入exit时，触发了ExitCommand.ExecuteCommand方法，服务端主动断开连接，终端退出。
