Delphi IdTcpServer IdTcpClient 传输简单文本

已经很久敲代码了，想找一段直接Delphi11 TCP简单文本传输，费劲！

其实非常简单，因为Delphi11已经基于宽字符串了，所以,老猿们会想多，不多说上代码：

服务端：

procedure TMainForm.IdTCPServer1Execute(AContext: TIdContext);
var
    s:String;
begin
    AContext.Connection.IOHandler.DefStringEncoding := IndyTextEncoding_UTF8;
    begin
        FStrStream.Clear;
        AContext.Connection.IOHandler.ReadStream(FStrStream, -1, False);
        FStrStream.Position := 0;
        ShowTip( FStrStream.DataString, 50000 );
    end;
end;

客户端：

procedure TMainForm.SpeedButton7Click(Sender: TObject);
var Len:Int64;
    s : String;
begin
try
    s   := Trim(TipContent.text);
    s   := StringReplace( s, #10, '',  [rfReplaceAll, rfIgnoreCase] );
    s   := StringReplace( s, #13, '',  [rfReplaceAll, rfIgnoreCase] );
    s   := StringReplace( s, ' ', '',  [rfReplaceAll, rfIgnoreCase] );
    Len := length( s );
    if (Len > 32) then
    begin
      TipSendInfo.Caption := ' 超过32字未发送.';
      Exit;
    end else if ( Len < 1 ) then
             begin
                TipSendInfo.Caption := ' 无内容...';
                Exit;
             end
             else
                TipSendInfo.Caption:='';
    if not IdTCPClient1.Connected then
    begin
        IdTCPClient1.Host:=FShowTipIP;
        IdTCPClient1.Port:=FShowTipPort;
        IdTCPClient1.ConnectTimeout:=3000;
        IdTCPClient1.Connect;
    end;
    if not IdTCPClient1.Connected then
        TipSendInfo.Caption:='链接失败'
    else
    begin
        FStringStream.Clear;
        WriteStringToStream(FStringStream, Trim(s), enUTF8);
        IdTCPClient1.IOHandler.Write( FStringStream,0,true );
        TipSendInfo.Caption:=' 发送完成';
    end;
Except
    On E : Exception Do
    TipSendInfo.Caption := ' 异常：'+E.Message;
end;
end;

FStringStream 、FStrStream ： FStringStream:=TStringStream.Create(‘’,TEncoding.UTF8);

无握手协议，简单文本传输（差一点去翻原生Socket代码），好了就这些，去加个心跳。
