Selenium Java UnsupportedCommandException 未知命令：文件上传期间的 session/9845d50a442f6c23dc498210a0d253d7/se/file

Question

我正在使用 Selenium 版本：“4.12.1”和浏览器版本 112。但在文件上传过程中遇到困难。我正在使用

sendKeys

方法发送 xpath

//input[@type='file']

的文件路径。

规格：

我正在使用版本112的google chromedriver和版本4.1的selenium

驱动程序：RemoteWebDriver

代码：

WebElement fileInput = driver.findElement(By.xpath("//input[@type='file']"));  
String filePath = "/path/to/file.txt";  
fileInput.sendKeys(filePath);

堆栈跟踪：

我尝试了什么：

1. 我尝试使用 JavaScriptExecutor 使元素可见，但没有成功，因为问题在于 fileupload 向其发送请求的端点
2. 看到这篇文章链接，其中被告知要覆盖 UPLOAD_FILE 命令，但遇到了一些问题

使用Java中的Robot类实现文件路径复制粘贴，可以按照以下步骤操作：

使用 setClipboardData 函数将文件路径复制到剪贴板。 使用Robot类来模拟粘贴剪贴板内容并按Enter键的键盘动作。

公共类 FilePathPaster {

public static void setClipboardData(String filePath) {
    StringSelection stringSelection = new StringSelection(filePath);
    Toolkit.getDefaultToolkit().getSystemClipboard().setContents(stringSelection, null);
}

public static void pasteFilePath() throws AWTException {
    Robot robot = new Robot();

    // Simulate Ctrl+V
    robot.keyPress(KeyEvent.VK_CONTROL);
    robot.keyPress(KeyEvent.VK_V);
    robot.keyRelease(KeyEvent.VK_V);
    robot.keyRelease(KeyEvent.VK_CONTROL);

    // Simulate Enter key press
    robot.keyPress(KeyEvent.VK_ENTER);
    robot.keyRelease(KeyEvent.VK_ENTER);
}

public static void main(String[] args) {
    try {
        // Set the file path to clipboard
        String filePath = "C:\\path\\to\\your\\file.txt";
        setClipboardData(filePath);

        // Simulate the paste action and Enter key press
        pasteFilePath();
    } catch (AWTException e) {
        e.printStackTrace();
    }
}

}
