英文:
why cannot i upload an image to an upload input button using selenium? It works fine when opened manually but why doesn't it work through selenium?
问题
我有一个输入按钮，需要上传图像。HTML 代码如下：
<input type="file" name="files" data-file="" data-url="../upload/student/image" accept="image/*">
由于这个按钮会打开一个窗口，用于上传图像，我还尝试使用机器人类（robot class），但是按钮似乎无法被点击。
WebElement upload = driver.findElement(By.xpath("//*[@id=\"student_image\"]/input[1]"));
upload.click();
Robot robot = new Robot();
StringSelection string = new StringSelection("C:\\Users\\pradi\\OneDrive\\Desktop\\outline\\RHEST\\avatar.jpg");
Toolkit.getDefaultToolkit().getSystemClipboard().setContents(string, null);
robot.setAutoDelay(1000);
// Press Ctrl+V (Pressed)
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_V);
// Release Ctrl+V (Released)
robot.keyRelease(KeyEvent.VK_CONTROL);
robot.keyRelease(KeyEvent.VK_V);
robot.setAutoDelay(2000);
// Press Enter
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
但是出现了以下错误：
org.openqa.selenium.InvalidArgumentException: invalid argument
(Session info: chrome=83.0.4103.61)
...
为了找出代码在哪个位置停止工作，我在每一行代码中都尝试了 println，并发现从这一行开始代码停止工作：upload.click();。
我使用的 Chrome 版本为 83.0.4103.61。
英文:
I have an input button that demands an image upload. The html code looks something like this:
<input type="file" name="files" data-file="" data-url="../upload/student/image" accept="image/*">
since the button opens a windows screen from where we can upload the image, i also tried using robot class but The button is not being clicked somehow.
WebElement upload= driver.findElement(By.xpath("//*[@id=\"student_image\"]/input[1]"));
upload.click();
Robot robot= new Robot();
StringSelection string= new
StringSelection("C:\\Users\\pradi\\OneDrive\\Desktop\\outline\\RHEST\\avatar.jpg");
Toolkit.getDefaultToolkit().getSystemClipboard().setContents(string,null);
robot.setAutoDelay(1000);
Ctrl+V(Pressed)
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_V);
Ctrl+V(Released)
robot.keyRelease(KeyEvent.VK_CONTROL);
robot.keyRelease(KeyEvent.VK_V);
robot.setAutoDelay(2000);
//Press Enter
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
It is showing error:

Just to find out the the exact point where my code stopped working i tried println in each lines, and found out that from this line upload.click(); the code wasn't working
I'm using chrome Version 83.0.4103.61

代替：
upload.click();
使用：
uploadElement.sendKeys("path_to_image//example_image.png");
英文:
Instead of;
upload.click();
Use;
uploadElement.sendKeys("path_to_image//example_image.png");

你可以加入等待
WebDriverWait wait = new WebDriverWait(driver, 30);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id=\"student_image\"]/input[1]")))
.sendKeys("C:\\Users\\pradi\\OneDrive\\Desktop\\outline\\RHEST\\avatar.jpg");
请确认XPath并检查是否存在iframe。
英文:
You can join waiting
WebDriverWait wait = new WebDriverWait(driver, 30);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id=\"student_image\"]/input[1]"))
.sendKeys(C:\\Users\\pradi\\OneDrive\\Desktop\\outline\\RHEST\\avatar.jpg);
Please confirm xpath and Is there an iframe
