Question

仅显示可见屏幕截图的现有代码。我使用的是Chromedriver。

  System.setProperty("webdriver.chrome.driver", "D:/chromedriver/chromedriver.exe");
  WebDriver driver = new ChromeDriver();
  driver.get("http://www.bbc.com");       
  driver.manage().window().maximize();
  System.out.println(driver.getTitle());
  File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
  FileUtils.copyFile(scrFile, new File("D:/chromedriver/scr3.png"));
  driver.close();

Answer 1

你不能仅使用硒来做到这一点。您需要其他工具来执行任务。点击链接，查看我的回答：Screen shot issue in selenium webdriver

希望，它可以帮到你。

Answer 2

请找到以下代码，您可以根据需要滚动并截取屏幕截图。请注意elements Webelement。存储它们并相对滚动。您可以根据所需的屏幕截图进行滚动。

driver.get("http://www.bbc.com");       
driver.manage().window().maximize();
System.out.println(driver.getTitle());
File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(scrFile, new File("D:/chromedriver/scr3.png"));  
WebElement elements = driver.findElement(By.xpath(".//*[@id='page']/section[6]/div/div/div[1]/ul/li[3]/div/div[2]/h3/a"));    
Thread.sleep(3000L);
JavascriptExecutor js = (JavascriptExecutor) driver;
int yPosition = elements.getLocation().getY();
js.executeScript("window.scroll (0, " + yPosition + ") ");       
Thread.sleep(3000L);         
File scrFile1 = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(scrFile1, new File("D:/chromedriver/scr4.png"));
driver.close();

要获取完整网页的屏幕截图，我们必须使用名为“ aShot”的第三方实用程序。 aShot是一个WebDriver Schreenshot实用程序，使用它我们可以截取整个网页以及单个WebElement的屏幕截图。为此，我们必须下载aShot jar文件，并将其与Selenium jar文件一起添加到我们的项目中。

Answer 4

简短而可爱地使用Shutterbug：

public byte[] shootPage() throws IOException {
    BufferedImage image = Shutterbug.shootPage(driver, ScrollStrategy.WHOLE_PAGE).getImage();
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    ImageIO.write(image, "png", outputStream);
    return outputStream.toByteArray();
}

Answer 5

您可以尝试此方法。希望它会有用：-

public static void takeFullPageScreenShot(WebDriver driver) throws IOException {

    JavascriptExecutor jsExec = (JavascriptExecutor)driver;

    jsExec.executeScript("window.scrollTo(0, 0);"); //Scroll To Top

    Long innerHeight = (Long) jsExec.executeScript("return window.innerHeight;");
    Long scroll = innerHeight;

    Long scrollHeight = (Long) jsExec.executeScript("return document.body.scrollHeight;"); 

    scrollHeight = scrollHeight + scroll;

    do{

        File screenshot = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);

        //Unique File Name For Each Screenshot
        File destination = new File("E://screenshots//"+String.join("_", 
        LocalDateTime.now().toString().split("[^A-Za-z0-9]"))+".jpg");

        FileUtils.copyFile(screenshot, destination));

        jsExec.executeScript("window.scrollTo(0, "+innerHeight+");");

        innerHeight = innerHeight + scroll;

    }while(scrollHeight >= innerHeight);
}

Answer 6

尝试此代码。 AB D的上述响应存在一些逻辑错误。它们在下面解决：

public static void takeFullPageScreenShot(WebDriver driver) throws IOException {

    JavascriptExecutor jsExec = (JavascriptExecutor)driver;

    //Returns a Long, Representing the Height of the window’s content area.
    Long windowHeight = (Long) jsExec.executeScript("return window.innerHeight;");

    //Returns a Long, Representing the Height of the complete WebPage a.k.a. HTML document.
    Long webpageHeight = (Long) jsExec.executeScript("return document.body.scrollHeight;"); 

    //Marker to keep track of the current position of the scroll point
    //Long currentWindowScroll = Long.valueOf(0);
    //Using java's boxing feature to create a Long object from native long value.

    Long currentWindowScroll = 0L;

    do{
        //System.out.println(windowHeight + ", " + webpageHeight + ", " + currentWindowScroll);

        jsExec.executeScript("window.scrollTo(0, " + currentWindowScroll + ");");

        Actions act = new Actions(driver);
        act.pause(5000).perform();

        File tempScreenshot = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);

        //Unique File Name For Each Screenshot
        File destination = new File("C:\\core_java\\DemoScreenShot\\" + String.join("_", LocalDateTime.now().toString().split("[^A-Za-z0-9]"))+ ".png");

        Files.copy(tempScreenshot, destination);
        currentWindowScroll = currentWindowScroll + windowHeight;

    }while(currentWindowScroll <= webpageHeight);
}
