我試圖抓取網頁上存在的所有元素的屏幕截圖,並且希望將其存儲在我已寫入以下代碼的磁盤中。抓取頁面上所有元素的屏幕截圖
唯一的問題是這段代碼只適用於第一次迭代,之後會發生一些意想不到的事情。
List<WebElement> eleId = driver.findElements(By.xpath("//*[@id]")); //fetch all the elements with ID attribute
System.out.println(eleId.size());
for (int i = 0;i < eleId.size();i++) {
// Get entire page screenshot
File screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
BufferedImage fullImg = ImageIO.read(screenshot);
// Get the location of element on the page
Point point = eleId.get(i).getLocation();
// Get width and height of the element
int eleWidth = eleId.get(i).getSize().getWidth();
int eleHeight = eleId.get(i).getSize().getHeight();
// Crop the entire page screenshot to get only element screenshot
BufferedImage eleScreenshot = fullImg.getSubimage(point.getX(), point.getY(), eleWidth, eleHeight);
ImageIO.write(eleScreenshot, "png", screenshot);
// Creating variables name for image to be stores in the disk
String fileName = eleId.get(i).getAttribute("id");
String imageLocation = "D:\\" + fileName + ".png";
// System.out.println(imageLocation);
// Copy the element screenshot to disk
File screenshotLocation = new File(imageLocation);
FileUtils.copyFile(screenshot, screenshotLocation);
System.out.println("Screenshot has been stored.");
}
你是什麼意思意想不到的事情?你的腳本會拋出任何錯誤? –
它不會拋出任何錯誤,但只運行一次迭代。 –
