C#
public static void TakeScreenshot(IWebDriver driver, String filename)
{
// Take a screenshot and save it to filename
Screenshot screenshot = ((ITakesScreenshot)driver).GetScreenshot();
screenshot.SaveAsFile(filename, ImageFormat.Png);
}

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();
你可以在浏览器中截取网页可见部分的截图:
首先导入:
import java.io.File;
import com.google.common.io.Files;
Then
File src=((TakesScreenshot)driver).getScreenShotAs(OutputType.FILE);
Files.copy(src,new File("new path/pic.jpeg"));
另外,在Selenium4之后,你还可以截取webelement的截图:
WebElement element=driver.findElement(By.xpath("xpath
here"));
File src=element.getScreenShotAs(OutputType.FILE);
File.copy(src,new File("new path/pic.jpeg"));
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;
}
Java
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,可以使用Selenium WebDriver对网页进行快照。
WebDriver API提供的getScreenshotAs()方法为我们做了这项工作。
语法:getScreenshotAs(OutputType<X> target)
返回类型:X
参数:target—查看OutputType提供的选项
适用性:不特定于任何DOM元素
例子:
TakesScreenshot screenshot = (TakesScreenshot) driver;
File file = screenshot.getScreenshotAs(OutputType.FILE);
有关详细信息,请参阅下面的工作代码片段。
public class TakeScreenShotDemo {
public static void main(String[] args) {
WebDriver driver = new FirefoxDriver();
driver.manage().window().maximize();
driver.get(“http: //www.google.com”);
TakesScreenshot screenshot = (TakesScreenshot) driver;
File file = screenshot.getScreenshotAs(OutputType.FILE);
// Creating a destination file
File destination = new File(“newFilePath(e.g.: C: \\Folder\\ Desktop\\ snapshot.png)”);
try {
FileUtils.copyFile(file, destination);
} catch (IOException e) {
e.printStackTrace();
}
}
}
