简介

DotNettySocket是一个.NET跨平台Socket框架(支持.NET4.5+及.NET Standard2.0+),同时支持TcpSocket、WebSocket和UdpSocket,其基于微软强大的DotNetty框架,力求为Socket通讯提供简单高效优雅的操作方式。

安装方式:Nuget安装DotNettySocket即可

项目地址:https://github.com/Coldairarrow/DotNettySocket

产生背景

两年前最开始接触物联网的时候,需要用到Tcp及Udp通讯,为了方便使用,将原始的Socket进行了简单的封装,基本满足了需求,并将框架开源。但是由于精力及实力有限,没有进一步优化原框架。后来发现了强大的DotNetty框架,DotNetty是微软Azure团队开源基于Java Netty框架的移植版,其性能优异、维护团队强大,许多.NET强大的框架都使用它。DotNetty功能强大,但是用起来还是不够简洁(或许是个人感觉),刚好最近项目需要用到WebSocket,因此鄙人抽时间基于DotNetty进行简单封装了下,撸出一个力求简单、高效、优雅的Socket框架。

使用方式

TcpSocket

Tcp是面向连接的,所以服务端对连接的管理就至关重要,框架支持各种事件的处理、给连接设置连接名(身份标识)、通过连接名找到特定连接、连接收发数据、分包、粘包处理。

  • 服务端
using Coldairarrow.DotNettySocket;
using System;
using System.Text;
using System.Threading.Tasks;

namespace TcpSocket.Server
{
    class Program
    {
        static async Task Main(string[] args)
        {
            var theServer = await SocketBuilderFactory.GetTcpSocketServerBuilder(6001)
                .SetLengthFieldEncoder(2)
                .SetLengthFieldDecoder(ushort.MaxValue, 0, 2, 0, 2)
                .OnConnectionClose((server, connection) =>
                {
                    Console.WriteLine($"连接关闭,连接名[{connection.ConnectionName}],当前连接数:{server.GetConnectionCount()}");
                })
                .OnException(ex =>
                {
                    Console.WriteLine($"服务端异常:{ex.Message}");
                })
                .OnNewConnection((server, connection) =>
                {
                    connection.ConnectionName = $"名字{connection.ConnectionId}";
                    Console.WriteLine($"新的连接:{connection.ConnectionName},当前连接数:{server.GetConnectionCount()}");
                })
                .OnRecieve((server, connection, bytes) =>
                {
                    Console.WriteLine($"服务端:数据{Encoding.UTF8.GetString(bytes)}");
                    connection.Send(bytes);
                })
                .OnSend((server, connection, bytes) =>
                {
                    Console.WriteLine($"向连接名[{connection.ConnectionName}]发送数据:{Encoding.UTF8.GetString(bytes)}");
                })
                .OnServerStarted(server =>
                {
                    Console.WriteLine($"服务启动");
                }).BuildAsync();

            Console.ReadLine();
        }
    }
}
  • 客户端
using Coldairarrow.DotNettySocket;
using System;
using System.Net;
using System.Text;
using System.Threading.Tasks;

namespace UdpSocket.Client
{
    class Program
    {
        static async Task Main(string[] args)
        {
            var theClient = await SocketBuilderFactory.GetUdpSocketBuilder()
                .OnClose(server =>
                {
                    Console.WriteLine($"客户端关闭");
                })
                .OnException(ex =>
                {
                    Console.WriteLine($"客户端异常:{ex.Message}");
                })
                .OnRecieve((server, point, bytes) =>
                {
                    Console.WriteLine($"客户端:收到来自[{point.ToString()}]数据:{Encoding.UTF8.GetString(bytes)}");
                })
                .OnSend((server, point, bytes) =>
                {
                    Console.WriteLine($"客户端发送数据:目标[{point.ToString()}]数据:{Encoding.UTF8.GetString(bytes)}");
                })
                .OnStarted(server =>
                {
                    Console.WriteLine($"客户端启动");
                }).BuildAsync();

            while (true)
            {
                await theClient.Send(Guid.NewGuid().ToString(), new IPEndPoint(IPAddress.Parse("127.0.0.1"), 6003));
                await Task.Delay(1000);
            }
        }
    }
}

WebSocket

WebSocket与TcpSocket接口基本保持一致,仅有的区别就是TcpSocket支持字节的收发并且需要自行处理分包粘包。而WebSocket直接收发字符串(UTF-8)编码,并且无需考虑分包粘包。框架目前没有支持WSS,建议解决方案是使用Nginx转发即可(相关资料一搜便有)

  • 服务端
using Coldairarrow.DotNettySocket;
using System;
using System.Threading.Tasks;

namespace WebSocket.Server
{
    class Program
    {
        static async Task Main(string[] args)
        {
            var theServer = await SocketBuilderFactory.GetWebSocketServerBuilder(6002)
                .OnConnectionClose((server, connection) =>
                {
                    Console.WriteLine($"连接关闭,连接名[{connection.ConnectionName}],当前连接数:{server.GetConnectionCount()}");
                })
                .OnException(ex =>
                {
                    Console.WriteLine($"服务端异常:{ex.Message}");
                })
                .OnNewConnection((server, connection) =>
                {
                    connection.ConnectionName = $"名字{connection.ConnectionId}";
                    Console.WriteLine($"新的连接:{connection.ConnectionName},当前连接数:{server.GetConnectionCount()}");
                })
                .OnRecieve((server, connection, msg) =>
                {
                    Console.WriteLine($"服务端:数据{msg}");
                    connection.Send(msg);
                })
                .OnSend((server, connection, msg) =>
                {
                    Console.WriteLine($"向连接名[{connection.ConnectionName}]发送数据:{msg}");
                })
                .OnServerStarted(server =>
                {
                    Console.WriteLine($"服务启动");
                }).BuildAsync();

            Console.ReadLine();
        }
    }
