socket.core

This is a socket framework based on C # net standard2.0 write, can be used for .NET Framework / dotnet core assembly, can run in window (IOCP) / linux (epoll) .Use asynchronous connection, asynchronous send, asynchronous receive, Performance burst tables, and pass the stress test.
.NET Framework4.0 version https://github.com/fengma312/socket.framework

下面有中文文档

Install NuGet: https://www.nuget.org/packages/socket.core/
Package Manager: Install-Package socket.core
.Net CLI: dotnet add package socket.core
Paket CLI: paket add socket.core
One: TCP module introduction
Server socket.core.Server namespace, respectively, three modes push / pull / pack Under the socket.core.
Client namespace of the client, there are three modes of push / pull / pack

The main process and the corresponding methods and events introduced.
Note: connectId (guid) represents a connection object, data (byte []), success (bool)
  

    1. Initialize socket (corresponding to the three modes)

    Instantiate the server class TcpPushServer / TcpPullServer / TcpPackServer
    Instantiate the client class TcpPushClient / TcpPullClient / TcpPackClient Parameter introduction int numConnections maximum number of simultaneous connections, int receiveBufferSize buffer size (sink) for each socket I / O operation, int overtime timeout period in seconds (check every 10 seconds), When the value is 0, do not set the timeout, uint headerFlag Header tag range 0 ~ 1023 (0x3FF), when the header identifier is equal to 0, do not check the header

    1. Start monitoring / connecting server

    Server server.Start (port);
    Client client.Connect (ip, port);

    1. Trigger the connection event

    Server server.OnAccept (connectId); Received a connection id, can be used to send, receive, close the tag
    Client client.OnConnect(success); Receives whether to connect to the server successfully

    1. Send a message

    Server server.Send (connectId, data, offset, length);
    Client client.Send (data, offset, length);

    1. Trigger sent events

    Server server.OnSend (connectId, length);
    Client client.OnSend (length);

    1. Triggered receive events

    Server server.OnReceive (connectId, data);
    Client client.OnReceive (data);

    1. Close the connection

    Server server.Close (connectId);
    Client client.Close ();

    1. Trigger to close the connection event

    Server server.OnClose (connectId);
    Client client.OnClose ();

Three models introduction

  • One: push

    Will trigger the monitor event object OnReceive (connectId, data); the data immediately "pushed" to the application

  • Two: pull

    OnReceive (connectId, length), which tells the application how much data has been received. The application checks the length of the data. If it meets, it calls the Fetch (connectId, length) method of the component, Data "pulled" out

  • Three: pack

    pack The model component is a combination of the push and pull models. The application does not have to deal with subcontracts. The component guarantees that every application server.OnReceive (connectId, data) /client.OnReceive (data) event provides the application with a Complete data package Note: The pack model component automatically adds a 4-byte (32-bit) header to each packet sent by the application. When the component receives the data, it is automatically packetized based on the header information. Each complete packet is sent to OnReceive The event is sent to the application PACK header format(4 byte)4*8=32
    XXXXXXXXXXYYYYYYYYYYYYYYYYYYYYYY
    The first 10 X bits are the header identification bits, which are used for data packet verification. The effective header identification value ranges from 0 to 1023 (0x3FF). When the header identification equals 0, the header is not checked. The last 22 bits of Y are length bits. Package length. The maximum valid packet length can not exceed 4194303 (0x3FFFFF) bytes (bytes), the application can be set by the TcpPackServer / TcpPackClient constructor parameter headerFlag

Server other methods introduced

    1. bool SetAttached(int connectId, object data)

The server sets additional data for each client to prevent the user from establishing the user mapping table

    1. T GetAttached(int connectId)

Get additional data for the specified client

    1. Attributes:ConcurrentDictionary<int, string> ClientList

Get the client information being connected <connectId, ip and port>

Two: UDP module introduction

    1. Initialize the UDP implementation class UdpServer / UdpClients

    Server socket.core.Server.UdpServer
    Client socket.core.Client.UdpClients
    Parameters int receiveBufferSize Buffer size for each socket I / O operation (receiver)

    1. Send data

    Server server.Send (remoteEndPoint, data, offset, length)
    Client client.Send (data, offset, length)
    Client client.Send(remoteEndPoint,data,offset,length)

    1. Trigger sent events

    Server server.OnSend (remoteEndPoint, length)
    Client client.OnSend (length)

    1. Trigger the receiving event

    Server server.OnReceive (remoteEndPoint, data, offset, length)
    Client client.OnReceive (data, offset, length)

socket.core

这是一个基于C# .net standard2.0 写的socket框架,可使用于.net Framework/dotnet core程序集,能在window(IOCP)/linux(epoll)运行.使用异步连接,异步发送,异步接收,性能爆表,并且通过压力测试。

安装NuGet: https://www.nuget.org/packages/socket.core/
Package Manager: Install-Package socket.core
.Net CLI :dotnet add package socket.core
Paket CLI:paket add socket.core

一:TCP模块介绍

服务端所在socket.core.Server命名空间下,分别为三种模式 push/pull/pack
客户端所在socket.core.Client命名空间下,分别为三种模式 push/pull/pack

主要流程与对应的方法和事件介绍.
注:connectId(int)代表着一个连接对象,data(byte[]),success(bool)

  • 1.初始化TCP实现类(对应的三种模式)

    实例化服务端类 TcpPushServer/TcpPullServer/TcpPackServer
    实例化客户端类 TcpPushClient/TcpPullClient/TcpPackClient
    参数介绍int numConnections同时处理的最大连接数,int receiveBufferSize用于每个套接字I/O操作的缓冲区大小(接收端), int overtime超时时长,单位秒.(每10秒检查一次),当值为0时,不设置超时,uint headerFlag包头标记范围0~1023(0x3FF),当包头标识等于0时,不校验包头

  • 2.启动监听/连接服务器

    服务端 server.Start(port);
    客户端 client.Connect(ip,port);

  • 3.触发连接事件

    服务端 server.OnAccept(connectId); 接收到一个连接id,可用他来发送,接收,关闭的标记
    客户端 client.OnConnect(success); 接收是否成功连接到服务器

  • 4.发送消息

    服务端 server.Send(connectId,data,offset,length);
    客户端 client.Send(data,offset,length);

  • 5.触发已发送事件

    服务端 server.OnSend(connectId,length);
    客户端 client.OnSend(length);

  • 6.触发接收事件

    服务端 server.OnReceive(connectId, data);
    客户端 client.OnReceive(data);

  • 7.关闭连接

    服务端 server.Close(connectId);
    客户端 client.Close();

  • 8.触发关闭连接事件

    服务端 server.OnClose(connectId);
    客户端 client.OnClose();

三种模型简介

  • 一:push

    当接收到数据时会触发监听事件OnReceive(connectId,data);把数据立马“推”给应用程序

  • 二:pull

    当接收到数据时会触发监听事件OnReceive(connectId,length),告诉应用程序当前已经接收到了多少数据长度,应用程序可使用GetLength(connectId)方法检查已接收的数据的长度,如果满足则调用组件的Fetch(connectId,length)方法,把需要的数据“拉”出来

  • 三:pack

    pack模型组件是push和pull模型的结合体,应用程序不必要处理分包/合包,组件保证每个server.OnReceive(connectId,data)/client.OnReceive(data)事件都向应用程序提供一个完整的数据包
    注:pack模型组件会对应用程序发送的每个数据包自动加上4个字节(32bit)的包头,组件接收到数据时,根据包头信息自动分包,每个完整的数据包通过OnReceive(connectId, data)事件发送给应用程序
    PACK包头格式(4字节)4*8=32
    XXXXXXXXXXYYYYYYYYYYYYYYYYYYYYYY
    前10位X为包头标识位,用于数据包校验,有效包头标识取值范围0~1023(0x3FF),当包头标识等于0时,不校验包头,后22位Y为长度位,记录包体长度。有效数据包最大长度不能超过4194303(0x3FFFFF)字节(byte),应用程序可以通过TcpPackServer/TcpPackClient构造函数参数headerFlag设置

服务端其它方法介绍

    1. bool SetAttached(int connectId, object data)

    服务端为每个客户端设置附加数据,避免用户自己再建立用户映射表

    1. T GetAttached(int connectId)

    获取指定客户端的附加数据

    1. 属性:ConcurrentDictionary<int, string> ClientList

    获取正在连接的客户端信息<connectId,ip和端口>

二:UDP模块介绍

  • 1.初始化UDP实现类UdpServer/UdpClients

    服务端socket.core.Server.UdpServer
    客户端socket.core.Client.UdpClients
    参数int receiveBufferSize用于每个套接字I/O操作的缓冲区大小(接收端)

  • 2.发送数据

    服务端 server.Send(remoteEndPoint,data,offset,length)
    客户端 client.Send(data,offset,length)
    客户端 client.Send(remoteEndPoint,data,offset,length)

  • 3.触发已发送事件

    服务端 server.OnSend(remoteEndPoint,length)
    客户端 client.OnSend(length)

  • 3.触发接收事件

    服务端 server.OnReceive(remoteEndPoint,data,offset,length)
    客户端 client.OnReceive(data,offset,length)
