How Create VCL WebSocket Client

Example: open a websocket connection to echo.websocket.org

  1. Create a new VCL Forms Application 

  2. Drop a TsgcWebSocketClient in a Form and configure Host and Port Properties to connect to Server.

    sgcWebSocketClient1.Host := 'echo.websocket.org';

    sgcWebSocketClient1.Port := 80;

  3. Drop a TButton in a Form, Double Click and type this code:

   sgcWebSocketClient1.Active := True;

  4. Drop a TButton in a Form, Double Click and type this code:

   sgcWebSocketClient1.WriteData('Hello Server From VCL Client');

  5. Build Project and that's all, you have configured a basic WebSocket Client.

How Create VCL WebSocket Server

Example: create a server which listen on port 80

  1. Create a new VCL Forms Application 

  2. Drop a TsgcWebSocketServer in a Form and set listening port

      sgcWebsocketServer1.Port := 80;

  3. On Events Tab, Double click OnMessage Event, and type following code:

      ShowMessage('Message Received From Client: ' + Text);

  4. Drop a TButton in a Form, Double Click and type this code:

      sgcWebSocketServer1.Active := True;

   5. Build Project and that's all, you have configured a basic WebSocket Server.

How Create Linux WebSocket Server

Example: Simple Server listening on port 5000.

program sgcWebSockets_linux;

{$APPTYPE CONSOLE}

{$R *.res}

uses

  System.SysUtils, sgcWebSocket;

var

  oServer: TsgcWebSocketServer;

begin

  try

    oServer := TsgcWebSocketServer.Create(nil);

    oServer.Port := 5000;

    oServer.Active := True;

 

    while oServer.Active do

      Sleep(10);

  except

    on E: Exception do

      Writeln(E.ClassName, ': ', E.Message);

  end;

 

end.

WebBrowser Client

Example: open a websocket connection to 127.0.0.1:8000

  1. Create a new html file

  2. Open file with a text editor and copy following code:

<html>

<head>

<script type="text/javascript" src="http://127.0.0.1:8000/sgcWebSockets.js"></script>

</head>

<body>

<a href="javascript:var socket = new sgcWebSocket('ws://127.0.0.1:8000');">Open</a>

<a href="javascript:socket.send('Hello Server From Web Browser');">Send</a>

</body>

</html>
