用Java發送斜槓和反斜槓

使用Java機器人時，發送斜槓或反斜槓時會引發異常。用Java發送斜槓和反斜槓

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); 
}

然後，當我要輸入這些，我用：

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."); } 


}

我在控制檯中看到兩個錯誤信息。順便說一句，我試圖發送的所有其他擊鍵工作正常。

我得到斜線follwowing堆棧跟蹤：

反斜線的工作，而且還拋出IllegalArgumentException：

有什麼辦法，我可以送斜線和反斜線按鍵嗎？

如果適用，請*總是*包含'e.printStackTrace（）'的結果。 – Vulcan

那麼，而不是隻是打印出那裏*是一個例外，爲什麼不打印出例外的細節？ –

好的，我會添加它。 –

好的，我發現了一個解決方案，可以方便用戶使用不同的鍵盤佈局。它使用Alt代碼。

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); 

}

然後調用它像這樣：

對於反斜槓： alt(KeyEvent.VK_NUMPAD0, KeyEvent.VK_NUMPAD0, KeyEvent.VK_NUMPAD9, KeyEvent.VK_NUMPAD2);

對於常年偏多： alt(KeyEvent.VK_NUMPAD0, KeyEvent.VK_NUMPAD0, KeyEvent.VK_NUMPAD4, KeyEvent.VK_NUMPAD7);

沒有例外。也適用於所有其他角色。但在使用這個時確保你有Num Lock。

+1，創造性思維。如果這是您的最終解決方案，請將其標記爲已接受 – Vulcan

爲了改進，不要在每次調用該方法時都使用新的'Robot'。 – Vulcan

@Vulcan這是一個好主意......順便說一下，感謝+1 –

（對不起，我應該提到這不是一個答案，只是說它對我有用，所以我猜這是一個配置問題或某事 - 但我認爲這是別人可能會發現的方便。它應該是一個評論，但由於技術原因，我必須使它成爲答案）

我沒有與機器人類搞砸了，只是花了一個有趣的半小時搞亂和建立在這個很酷的Java類頂部的一些東西。

對於我發送斜槓和反斜槓工作正常。由於VK _？東西很好地映射到ASCII字符，你可以發送'\'或'/'，它也可以工作。

我使用了Groovy，因爲這就是我在這些日子裏玩的，但這裏有一個很好的例子和一堆我剛纔想到的可重用代碼。它被編寫成腳本，但可以很容易地轉換爲Groovy或Java中的類（我將盡快這樣做）。

這必須從「Priviliged」shell運行（例如，右鍵單擊命令提示符並選擇「以管理員身份運行」）。

它也必須有時間讓你放開鍵盤！（瞭解到這一點很困難），所以如果你使用groovyShell並使用alt-r來運行它，那麼一定要在發送第一個鍵之前放置1秒的延遲，否則你的ALT將成爲按下鍵的一部分。

 
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) 
}
