Ruby
require 'rubygems'
require 'selenium-webdriver'
driver = Selenium::WebDriver.for :ie
driver.get "https://www.google.com"
driver.save_screenshot("./screen.png")
更多的文件类型和选项可用,您可以在文件takes_screenshot.rb中看到它们。

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
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 void captureScreenShot(String obj) throws IOException {
File screenshotFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(screenshotFile, new File("Screenshots\\" + obj + "" + GetTimeStampValue() + ".png"));
}
public String GetTimeStampValue()throws IOException{
Calendar cal = Calendar.getInstance();
Date time = cal.getTime();
String timestamp = time.toString();
System.out.println(timestamp);
String systime = timestamp.replace(":", "-");
System.out.println(systime);
return systime;
}
使用这两种方法,您还可以拍摄带有日期和时间的屏幕截图。

我解决了这个问题。你可以扩展RemoteWebDriver,给它所有的接口,它的代理驱动程序实现:
WebDriver augmentedDriver = new Augmenter().augment(driver);
((TakesScreenshot)augmentedDriver).getScreenshotAs(...); // It works this way
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();
