如何通过Selenium和Java使用AShot库获取完整的屏幕截图

Question

我尝试了以下代码以截取全屏截图。但是只有可见区域被捕获了，

public void Fullscreen (WebDriver driver) 
{
    try {
        final Screenshot screenshot = new AShot().shootingStrategy(ShootingStrategies.viewportPasting(1000)).takeScreenshot(driver);
        final BufferedImage image = screenshot.getImage();
        ImageIO.write(image, "PNG", new File("D:\\" + "AShot_BBC_Entire.png"));           
    } catch(Exception e){
        System.out.println(e.getMessage());
    }
}

使用 ashot-1.4使用 Selenium Java Client v3.14.0 ， ChromeDriver v2.41 ， Chrome v 68.0 时。 4.jar 这是一个使用 ChromeDriver 和 aShot Library 的完整页面屏幕截图水平和垂直拍摄的示例em> url https://jquery.com/：

          WebDriver driver =  new ChromeDriver(options);
          driver.get("https://jquery.com/");
          new WebDriverWait(driver, 20).until(ExpectedConditions.titleContains("jQuery"));
          Screenshot myScreenshot = new AShot().shootingStrategy(ShootingStrategies.viewportPasting(100)).takeScreenshot(driver);
          ImageIO.write(myScreenshot.getImage(),"PNG",new File("./Screenshots/elementScreenshot.png"));
          driver.quit();
      }
  }

如果您不知道使用哪种屏幕，想添加答案。 （是否是视网膜）

在这种情况下，您需要找到浏览器窗口的devicePixelRatio：

Object output = ((JavascriptExecutor) webDriver).executeScript("return window.devicePixelRatio");
String value = String.valueOf(output);
float windowDPR = Float.parseFloat(value);

然后，您可以缩放使用ShootingStrategy;

ShootingStrategy shootingStrategy = ShootingStrategies.viewportPasting(ShootingStrategies.scaling(windowDPR), 100)
