示例
使用本组件库可以非常简单方便的构造属于你自己的websocket服务器,从而实现和其他的客户端进行通信,尤其是和网页进行通讯,
简单的实例化
// 定义一个对象
// Define an object
public WebSocketServer webSocketServer;

public void Start( )
{
    try
    {
        webSocketServer = new WebSocketServer( );
        webSocketServer.ServerStart( 1883 );
    }
    catch(Exception ex)
    {
        Console.WriteLine( ex.Message );
    }
}
当客户端发送数据给服务器的时候,会发一个事件,并且把当前的会话暴露出来,下面举例打印消息,并且演示一个例子,发送数据给指定的会话。
接触数据
public WebSocketServer webSocketServer;

public void Start( )
{
    try
    {
        webSocketServer = new WebSocketServer( );
        webSocketServer.OnClientApplicationMessageReceive += WebSocketServer_OnClientApplicationMessageReceive;
        // 如果要控制心跳时间,需要在ServerStart方法调用之前
        webSocketServer.KeepAliveSendInterval = TimeSpan.FromSeconds( 20 ); // 默认间隔30秒发送客户端一次心跳
        webSocketServer.KeepAlivePeriod = TimeSpan.FromSeconds( 100 );      // 如果100秒之内都没有任何的心跳回复,就认为掉线了
        webSocketServer.ServerStart( 1883 );
    }
    catch (Exception ex)
    {
        Console.WriteLine( ex.Message );
    }
}

private void WebSocketServer_OnClientApplicationMessageReceive( WebSocketSession session, WebSocketMessage message )
{
    // 当接收到客户端的数据的时候触发,session参数就是会话信息,你可以选择打印数据,或是回发数据
    // Triggered when data is received from the client. The session parameter is the session information. You can choose to print the data or send it back.
    Console.WriteLine( message.ToString( ) );
    webSocketServer.SendClientPayload( session, "I hava received your data, thank you" );
}
也可以在其他地方发送数据给所有的客户端,只要调用一个方法就可以了。
发送数据
// 以下的信息会发布到所有的连接的客户端,包括网页端或是桌面程序
// The following information will be published to all connected clients, including web or desktop
private void Button1_Click(object sender, EventArgs e )
{
    webSocketServer.PublishAllClientPayload( "This is sample data, thank you for use hslcommunication" );
}
当客户端上线之后也触发了当前的事件,我们可以手动捕获到
捕获上线事件
public WebSocketServer webSocketServer;

public void Start( )
{
    try
    {
        webSocketServer = new WebSocketServer( );
        webSocketServer.OnClientApplicationMessageReceive += WebSocketServer_OnClientApplicationMessageReceive;
        webSocketServer.OnClientConnected += ( WebSocketSession session ) =>
        {
            Console.WriteLine( session.Remote.ToString( ) + " Online" );
        };
        webSocketServer.ServerStart( 1883 );
    }
    catch (Exception ex)
    {
        Console.WriteLine( ex.Message );
    }
}


private void WebSocketServer_OnClientApplicationMessageReceive( WebSocketSession session, WebSocketMessage message )
{
    // 当接收到客户端的数据的时候触发,session参数就是会话信息,你可以选择打印数据,或是回发数据
    // Triggered when data is received from the client. The session parameter is the session information. You can choose to print the data or send it back.
    Console.WriteLine( message.ToString( ) );
    webSocketServer.SendClientPayload( session, "I hava received your data, thank you" );
}
我们再来看看一个高级的操作,实现订阅,大多数的情况,websocket被设计成了订阅发布的操作。基本本服务器可以扩展出非常复杂功能的系统,我们来看一种最简单的操作。
客户端给服务器发的数据都视为主题(topic),这样服务器就可以辨认出主题信息,并追加主题。如下这么操作。
订阅实现
public WebSocketServer webSocketServer;

public void Start( )
{
    try
    {
        webSocketServer = new WebSocketServer( );
        webSocketServer.OnClientApplicationMessageReceive += WebSocketServer_OnClientApplicationMessageReceive;
        webSocketServer.ServerStart( 1883 );
    }
    catch (Exception ex)
    {
        Console.WriteLine( ex.Message );
    }
}

private void WebSocketServer_OnClientApplicationMessageReceive( WebSocketSession session, WebSocketMessage message )
{
    // 客户端发过来的数据就是订阅的主题,服务器在收到数据后加入到订阅的数据信息里去,假如订阅的数据已经存在,会自动推送数据
    // The data sent by the client is the subject of the subscription. After receiving the data, the server adds it to the subscribed data information. 
    // If the subscribed data already exists, it will automatically push the data.
    Console.WriteLine( message.ToString( ) );
    string topic = Encoding.UTF8.GetString( message.Payload );
    if(!string.IsNullOrEmpty( topic ))
    {
        webSocketServer.AddSessionTopic( session, topic );
    }
}
然后在发布的时候,调用下面的代码。
发布数据
// 以下的信息会发布到所有的连接的客户端,包括网页端或是桌面程序
// The following information will be published to all connected clients, including web or desktop
private void Button1_Click( object sender, EventArgs e )
{
    webSocketServer.PublishClientPayload( "A", "This is sample data, thank you for use hslcommunication" );
}
可以看到,我们这里只有订阅操作,如果想要实现更为复杂的操作怎么办?丰富客户端发来的数据,携带命令,数据,就可以区分了。比如json数据。具体的实现需要看各位能力了。
