TWebSocketClient
支持WEBSOCKET通讯协议的客户端控件。
连接WEBSOCKET SERVER的代码演示:
WebSocketClient1.HostName := ‘88.198.69.227‘;
WebSocketClient1.Port := 8888;
WebSocketClient1.Disconnect;
WebSocketClient1.Connect;
接收数据事件:
procedure TForm43.WebSocketClient1DataReceived(Sender: TObject; Origin: string; Data: TJSObject); var it: TTMSFNCListBoxItem; sl: TStringList; s: String; n: string; v: string; begin lst.BeginUpdate; it := lst.Items.Add; s := Data.toString; sl := TStringList.Create; try TTMSFNCUtils.Split(‘~‘, s, sl); if sl.Count > 2 then begin n := ‘<font color="‘+sl[0]+‘" size="16">‘+sl[1]; v := sl[2]; it.Text := n + ‘ says: </font><font size="16">‘ + v+‘</font>‘; end; finally sl.Free; end; lst.EndUpdate; end;
发送数据演示:
procedure TForm43.SendMessage; var s: string; begin if FConnected and (WebEdit2.Text <> ‘‘) then begin s := TTMSFNCGraphics.ColorToHTML(TMSFNCColorPicker1.SelectedColor) + ‘~‘ + WebEdit1.Text + ‘~‘ + WebEdit2.Text; // limit message length s := Copy(s,1,256); WebSocketClient1.Send(s); WebEdit2.Text := ‘‘; end; end;
