PHP

public function takescreenshot($event)
  {
    $errorFolder = dirname(dirname(__FILE__)) . DIRECTORY_SEPARATOR . "ErrorScreenshot";

    if(!file_exists($errorFolder)){
      mkdir($errorFolder);
    }

    if (4 === $event->getResult()) {
      $driver = $this->getSession()->getDriver();
      $screenshot = $driver->getWebDriverSession()->screenshot();
      file_put_contents($errorFolder . DIRECTORY_SEPARATOR . 'Error_' .  time() . '.png', base64_decode($screenshot));
    }
  }

Java

public String captureScreen() {
    String path;
    try {
        WebDriver augmentedDriver = new Augmenter().augment(driver);
        File source = ((TakesScreenshot)augmentedDriver).getScreenshotAs(OutputType.FILE);
        path = "./target/screenshots/" + source.getName();
        FileUtils.copyFile(source, new File(path)); 
    }
    catch(IOException e) {
        path = "Failed to capture screenshot: " + e.getMessage();
    }
    return path;
}

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();

Java

这里似乎没有-在Java中截取一个特定元素的截图:

public void takeScreenshotElement(WebElement element) throws IOException {
    WrapsDriver wrapsDriver = (WrapsDriver) element;
    File screenshot = ((TakesScreenshot) wrapsDriver.getWrappedDriver()).getScreenshotAs(OutputType.FILE);
    Rectangle rectangle = new Rectangle(element.getSize().width, element.getSize().height);
    Point location = element.getLocation();
    BufferedImage bufferedImage = ImageIO.read(screenshot);
    BufferedImage destImage = bufferedImage.getSubimage(location.x, location.y, rectangle.width, rectangle.height);
    ImageIO.write(destImage, "png", screenshot);
    File file = new File("//path//to");
    FileUtils.copyFile(screenshot, file);
}

Python

def test_url(self):
    self.driver.get("https://www.google.com/")
    self.driver.save_screenshot("test.jpg")

它将在脚本保存的同一目录下保存一个截图。

File scrFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
BufferedImage originalImage = ImageIO.read(scrFile);
//int type = originalImage.getType() == 0 ? BufferedImage.TYPE_INT_ARGB : originalImage.getType();
BufferedImage resizedImage = CommonUtilities.resizeImage(originalImage, IMG_HEIGHT, IMG_WIDTH);
ImageIO.write(resizedImage, "jpg", new File(path + "/"+ testCaseId + "/img/" + index + ".jpg"));
Image jpeg = Image.getInstance(path + "/" + testCaseId + "/img/"+ index + ".jpg");
