Mac环境下无input标签时Selenium Java上传CSV文件失败求助

点击上传按钮后会打开桌面应用窗口以选择CSV文件，但页面中没有file类型的input标签，导致Send Keys方法无法生效，Robot类也无法正常工作。

我尝试了Send Keys和Robot类两种方法，但都没能解决问题，希望能得到帮助。

我使用的Robot类代码如下：

StringSelection stringSelection= new StringSelection(file.getAbsolutePath());
//Copy to clipboard 
Toolkit.getDefaultToolkit().getSystemClipboard().setContents(stringSelection, null);
browserDriver.waitTime(MainConfig.timeout_for_AJAX);
Robot robot = new Robot();

// Cmd + Tab is needed since it launches a Java app and the browser looses focus
robot.keyPress(KeyEvent.VK_META);
robot.keyPress(KeyEvent.VK_TAB);
robot.delay(1000);
robot.keyRelease(KeyEvent.VK_META);
robot.keyRelease(KeyEvent.VK_TAB);
robot.delay(1000);

//Open Goto window
robot.keyPress(KeyEvent.VK_META);
robot.keyPress(KeyEvent.VK_SHIFT);
robot.keyPress(KeyEvent.VK_G);
robot.keyRelease(KeyEvent.VK_META);
robot.keyRelease(KeyEvent.VK_SHIFT);
robot.keyRelease(KeyEvent.VK_G);

//Paste the clipboard value
robot.keyPress(KeyEvent.VK_META);
robot.keyPress(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_META);
robot.keyRelease(KeyEvent.VK_V);

//Press Enter key to close the Goto window and Upload window
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
robot.delay(1000);
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
