此例為上傳圖片：

ublic class up {

    public  static  void main(String[] args) throws Exception {

        //驅動設定
        System.setProperty("webdriver.chrome.driver", "D:\\driver\\chromedriver.exe");
        WebDriver driver = new ChromeDriver ();
        driver.manage ().window ().maximize ();
        driver.get ( "http://www.baidu.com" );

        //指定圖片路徑
        StringSelection ss=new StringSelection ( " C:\\Users\\quelingfei\\Desktop\\2018111601.jpg");

        //圖片路徑複製到剪貼簿
        Toolkit.getDefaultToolkit ().getSystemClipboard ().setContents ( ss,null );
        System.out.println ("selection" + ss);

        //點選相機按鈕
        driver.findElement ( By.xpath ("//*/span[@class='soutu-btn']") ).click ();

        //點選本地上傳圖片
        driver.findElement ( By.xpath ("//*/input[@class='upload-pic']") ).click ();

        Thread.sleep ( 2000 );

        Robot robot = new Robot ( );
        Thread.sleep ( 2000 );
        robot.keyPress ( KeyEvent.VK_ENTER );

        // 釋放回車
        robot.keyRelease(KeyEvent.VK_ENTER);

        // 按下 CTRL+V
        robot.keyPress(KeyEvent.VK_CONTROL);
        robot.keyPress(KeyEvent.VK_V);

        // 釋放 CTRL+V
        robot.keyRelease(KeyEvent.VK_CONTROL);
        robot.keyRelease(KeyEvent.VK_V);
        Thread.sleep(1000);

        // 點選回車 Enter
        robot.keyPress(KeyEvent.VK_ENTER);
        robot.keyRelease(KeyEvent.VK_ENTER);

        driver.quit ();
    }
