我如何从Facebook页面获取完整帖子的屏幕截图

Question

在此处输入映像说明当我从Facebook页面进行每个帖子的屏幕截图时，我只会得到一个部分缩放后的帖子。

代码：

post = browser.find_element_by_xpath("class")
browser.execute_script("document.body.style.zoom='80%'")
screen = post.screenshot_as_png
im = Image.open(BytesIO(screen))
im.save('image.png')

Answer 1

XPath的屏幕截图：

Selenium没有尝试将页面格式化以进行屏幕截图，而是可以通过XPath捕获屏幕截图 。请参阅以下代码：

post = browser.find_element_by_xpath("class")
post.screenshot("post.png")

        // Initialize browser
        WebDriver driver = new ChromeDriver();
        
        //navigate to url
        driver.get("https://demoqa.com");

        // capture screenshot and store the image
        Screenshot s=new AShot().shootingStrategy(ShootingStrategies.viewportPasting(1000)).takeScreenshot(driver);
        ImageIO.write(s.getImage(),"PNG",new File("C:\\projectScreenshots\\fullPageScreenshot.png"));
        
        //closing the webdriver
        driver.close();
    }
}
