Question

使用Java机器人时，发送斜杠或反斜杠会引发异常。

例如：

public void slash() throws AWTException {
    Robot rob = new Robot();
    rob.keyPress(KeyEvent.VK_SLASH);
    rob.keyRelease(KeyEvent.VK_SLASH);
}

public void backSlash() throws AWTException {
    Robot rob = new Robot();
    rob.keyPress(KeyEvent.VK_BACK_SLASH);
    rob.keyRelease(KeyEvent.VK_BACK_SLASH);
}

然后，当我想输入那些时，我使用：

public void type() {

    try {
        slash();
    } catch (AWTException e) { System.out.println("Exception when typing slash."); }

    try {
        backSlash();
    } catch (AWTException e) { System.out.println("Exception when typing back slash."); }


}

我在控制台中收到两条错误消息。顺便说一句，我试图发送的所有其他击键工作正常。

我得到了斜线的下面的堆栈跟踪：

反斜杠工作，但也抛出IllegalArgumentException：

有什么方法可以发送斜杠和反斜杠击键吗？

Answer 1

好的，我找到了一个解决方案，对于使用不同键盘布局的用户来说可能很方便。它使用Alt代码。

public static void alt(int event1, int event2, int event3, int event4) throws Exception {

    Robot bot = new Robot();
    bot.delay(50); //Optional
        bot.keyPress(KeyEvent.VK_ALT);

            bot.keyPress(event1);
            bot.keyRelease(event1);

            bot.keyPress(event2);
            bot.keyRelease(event2);

            bot.keyPress(event3);
            bot.keyRelease(event3);

            bot.keyPress(event4);
            bot.keyRelease(event4);

        bot.keyRelease(KeyEvent.VK_ALT);

}

然后你这样称呼它：

对于反斜杠： alt(KeyEvent.VK_NUMPAD0, KeyEvent.VK_NUMPAD0, KeyEvent.VK_NUMPAD9, KeyEvent.VK_NUMPAD2);

对于普通人： alt(KeyEvent.VK_NUMPAD0, KeyEvent.VK_NUMPAD0, KeyEvent.VK_NUMPAD4, KeyEvent.VK_NUMPAD7);

没有例外。也适用于所有其他角色。但请确保在使用时启用Num Lock。

Answer 2

（对不起，我应该提到这不是一个答案，只是说它确实对我有用，所以我猜它是配置问题或其他什么 - 但我认为这是其他人可能会发现的方便。它应该是一个评论，但由于技术原因，我必须作出答复）

我没有搞乱机器人类，只花了半个小时搞砸了，并在这个很酷的java类之上加入了一些东西。

对我来说，发送斜杠和反斜杠工作正常。自VK _ ???东西很好地映射到ASCII字符，你可以发送'\'或'/'，它也可以工作。

我使用了Groovy，因为这是我现在玩的东西，但这里有一个很好的例子和一堆可重复使用的代码。它是作为脚本编写的，但可以很容易地转换为Groovy或Java中的类（我很快就会这样做）。

必须从“Priviliged”shell运行（例如右键单击命令提示符并选择“以管理员身份运行”）。

还必须有时间让你放开键盘！（了解到困难的方法），所以如果你使用groovyShell并使用alt-r来运行它，请确保在发送第一个键之前放置1秒延迟，否则你的ALT将成为按下的键的一部分。

import java.awt.*
import java.awt.event.*
import static java.awt.event.KeyEvent.*

r=new Robot()
r.autoWaitForIdle = true
r.autoDelay=200 // Usually works with 0 but sometimes that's too fast.

// This will alt-tab you to your "Previous" app.  While testing I edited this in notepad++
// then tabbed out to a shell to execute it, this tabbed back into my editor and typed
// the "test" text.
alt VK_TAB

send "backslash=\\ \nforward slash =/"

// This will send any string
def send(String s)
{
    def difference = ("a" as Character) - ("A" as Character)
    s.each {
        Character c=it as Character
        if(c.isUpperCase()) {
            shift c
        } else if(c.isLowerCase()) {
            send(c - difference)
        } 
        else send(c)
    }
}

// These will work for integers and chars, NOT strings
def send(key)
{
    press(key as Integer)
    release(key as Integer)
}
def alt(key)
{
    press VK_ALT
    send key
    release VK_ALT
}
def shift(key)
{
    press VK_SHIFT
    send key
    release VK_SHIFT
}

def press(key)
{
    r.keyPress(key as Integer)
}
def release(int key)
{
    r.keyRelease(key as Integer)
}
