java - 如何使用Java Selenium WebDriver Ashot FireFox自动对网页的全屏截图包括固定元素

我使用java硒和ashot的组合来对网页进行全屏拍摄。

环境：

Firefox Quantum 66.0b10（64位）
geckodriver-v0.24.0-win64
jdk-8u201-windows-x64
apache-maven-3.6.0-bin

问题：

不幸的是，有一个固定的元素在我不需要的滚动时会保留在页面顶部。我只希望它在第一次滚动时显示一次，然后隐藏。

我尝试的是：

我试图在ashot takeScreen（）函数中找到用于滚动的代码，以调整滚动的高度，但找不到它。
我尝试更改Ashot的内置代码，但不允许（文件是只读的）

    //How to excute print screen for one time when class "chapter-nav scroll-to-fixed-fixed" is showed
    //then hidden "chapter-nav scroll-to-fixed-fixed"
    //and continue to takeScreenshot()
    js.executeScript("window.scrollTo(0,600)");
    js.executeScript("document.getElementsByClassName(\"chapter-nav scroll-to-fixed-fixed\")[0].classList.add(\"hidden\")");
    Screenshot screenshot = new AShot().shootingStrategy(ShootingStrategies.viewportPasting(100)).takeScreenshot(driver);
    BufferedImage image = screenshot.getImage();
    ImageIO.write(image, "PNG", new File("D:\\" + "DDD.png"));
    driver.close();

}

}

最佳答案

您可以使用<body> WebElement截取整个页面的屏幕截图

WebElement body = driver.findElement(By.tagName("body"));
File scrFile = ((TakesScreenshot)body).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(scrFile, new File("c:\\tmp\\screenshot.png"));
