是的，可以通过Selenium WebDriver来截屏。我目前使用Chrome驱动来抓取网站图片。请参考以下方法captureScreenshot()。

您还可以添加对web驱动程序的限制，例如

使用无头版的网页浏览器 当页面加载时禁用通知 启动全屏等。

如果一个网站配备了警报框，你的网页驱动程序将无法捕捉屏幕截图，因为异常将被抛出。在这种情况下，你需要关闭警告框，然后获取截图。下面的代码片段关闭警报框。

    public void captureScreenshot() throws InterruptedException, IOException {

        System.out.println("Creating Chrome Driver");

        // Set Chrome Driver
        System.setProperty("webdriver.chrome.driver", "D:\\chromedriver.exe");

        // Add arguments to Chrome Options
        ChromeOptions chromeOptions = new ChromeOptions();
        chromeOptions.addArguments("--headless");
        chromeOptions.addArguments("start-maximized");
        chromeOptions.addArguments("--disable-gpu");
        chromeOptions.addArguments("--start-fullscreen");
        chromeOptions.addArguments("--disable-extensions");
        chromeOptions.addArguments("--disable-popup-blocking");
        chromeOptions.addArguments("--disable-notifications");
        chromeOptions.addArguments("--window-size=1920,1080");
        chromeOptions.addArguments("--no-sandbox");
        chromeOptions.addArguments("--dns-prefetch-disable");
        chromeOptions.addArguments("enable-automation");
        chromeOptions.addArguments("disable-features=NetworkService");

        WebDriver driver = new ChromeDriver(chromeOptions);
        driver.get("https://www.google.com");
        System.out.println("Wait a bit for the page to render");
        TimeUnit.SECONDS.sleep(5);
        System.out.println("Taking Screenshot");
        File outputFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
        String imageDetails = "D:\\Images";
        File screenShot = new File(imageDetails).getAbsoluteFile();
        FileUtils.copyFile(outputFile, screenShot);
        System.out.println("Screenshot saved: {}" + imageDetails);
    }
}

为了接受警报框和获取截图:

String alertText = alert.getText();
System.out.println("ERROR: (ALERT BOX DETECTED) - ALERT MSG : " + alertText);
alert.accept();
File outputFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
String imageDetails = "D://Images"
File screenShot = new File(imageDetails).getAbsoluteFile();
FileUtils.copyFile(outputFile, screenShot);
System.out.println("Screenshot saved: {}" + imageDetails);
driver.close();

Ruby

time = Time.now.strftime('%a_%e_%Y_%l_%m_%p_%M_%S')
file_path = File.expand_path(File.dirname(__FILE__) + 'screens_shot')+'/'+time +'.png'
#driver.save_screenshot(file_path)
page.driver.browser.save_screenshot file_path

Java

是的，这是可能的。下面以Java为例:

WebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com/");
File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
// Now you can do whatever you need to do with it, for example copy somewhere
FileUtils.copyFile(scrFile, new File("c:\\tmp\\screenshot.png"));

JAVA

嗨，你可以在selenium中截图，这里是下面给出的代码，你可以在任何selenium项目中创建截图，我们也可以在aws中为失败的场景生成截图。

    public boolean takeScreenshot(final String name) {
    String screenshotDirectory = System.getenv("WORKING_DIRECTORY");
    File screenshot = 
    ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
    return screenshot.renameTo(new File(screenshotDirectory, 
    String.format("%s.png", name)));
    }

我使用下面的c#代码来获取整个页面或仅一个浏览器截图

    public void screenShot(string tcName)
    {
        try
        {
            string dateTime = string.Format("{0:yyyy-MM-dd_hh-mm-ss-tt}", DateTime.Now);
            string screenShotName = @"D:\Selenium\Project\VAM\VAM\bin" + "\\" + tcName + dateTime + ".png";
            ITakesScreenshot screen = driverScript.driver as ITakesScreenshot;
            Screenshot screenshot = screen.GetScreenshot();
            screenshot.SaveAsFile(screenShotName, System.Drawing.Imaging.ImageFormat.Png);
            if (driverScript.last == 1)
                this.writeResult("Sheet1", "Fail see Exception", "Status", driverScript.resultRowID);
        }
        catch (Exception ex)
        {
            driverScript.writeLog.writeLogToFile(ex.ToString(), "inside screenShot");
        }
    }

    public void fullPageScreenShot(string tcName)
    {
        try
        {
            string dateTime = string.Format("{0:yyyy-MM-dd_hh-mm-ss-tt}", DateTime.Now);
            string screenShotName = @"D:\Selenium\Project\VAM\VAM\bin" + "\\" + tcName + dateTime + ".png";
            Rectangle bounds = Screen.GetBounds(Point.Empty);
            using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
            {
                using (Graphics g = Graphics.FromImage(bitmap))
                {
                    g.CopyFromScreen(Point.Empty, Point.Empty, bounds.Size);
                }
                bitmap.Save(screenShotName, System.Drawing.Imaging.ImageFormat.Png);
            }
            if (driverScript.last == 1)
                this.writeResult("Sheet1", "Pass", "Status", driverScript.resultRowID);
        }
        catch (Exception ex)
        {
            driverScript.writeLog.writeLogToFile(ex.ToString(), "inside fullPageScreenShot");
        }
    }

Python

webdriver.get_screenshot_as_file(filepath)

上述方法将截取屏幕截图，并将其作为文件存储在作为参数提供的位置中。
