通过Selenium的Java和Python客户端，有多种方法可以使用Selenium WebDriver进行截图。

Java方法

下面是不同的Java截图方法:

Using getScreenshotAs() from the TakesScreenshot interface: Code block: package screenShot; import java.io.File; import java.io.IOException; import org.apache.commons.io.FileUtils; import org.openqa.selenium.OutputType; import org.openqa.selenium.TakesScreenshot; import org.openqa.selenium.WebDriver; import org.openqa.selenium.firefox.FirefoxDriver; import org.openqa.selenium.support.ui.ExpectedConditions; import org.openqa.selenium.support.ui.WebDriverWait; public class Firefox_takesScreenshot { public static void main(String[] args) throws IOException { System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe"); WebDriver driver = new FirefoxDriver(); driver.get("https://login.bws.birst.com/login.html/"); new WebDriverWait(driver, 20).until(ExpectedConditions.titleContains("Birst")); File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE); FileUtils.copyFile(scrFile, new File(".\\Screenshots\\Mads_Cruz_screenshot.png")); driver.quit(); } } Screenshot: If the webpage is jQuery enabled, you can use ashot from the pazone/ashot library: Code block: package screenShot; import java.io.File; import javax.imageio.ImageIO; import org.openqa.selenium.WebDriver; import org.openqa.selenium.firefox.FirefoxDriver; import org.openqa.selenium.support.ui.ExpectedConditions; import org.openqa.selenium.support.ui.WebDriverWait; import ru.yandex.qatools.ashot.AShot; import ru.yandex.qatools.ashot.Screenshot; import ru.yandex.qatools.ashot.shooting.ShootingStrategies; public class ashot_CompletePage_Firefox { public static void main(String[] args) throws Exception { System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe"); WebDriver driver = new FirefoxDriver(); driver.get("https://jquery.com/"); new WebDriverWait(driver, 20).until(ExpectedConditions.titleContains("jQuery")); Screenshot myScreenshot = new AShot().shootingStrategy(ShootingStrategies.viewportPasting(100)).takeScreenshot(driver); ImageIO.write(myScreenshot.getImage(),"PNG",new File("./Screenshots/firefoxScreenshot.png")); driver.quit(); } } Screenshot: Using selenium-shutterbug from assertthat/selenium-shutterbug library: Code block: package screenShot; import org.openqa.selenium.WebDriver; import org.openqa.selenium.firefox.FirefoxDriver; import com.assertthat.selenium_shutterbug.core.Shutterbug; import com.assertthat.selenium_shutterbug.utils.web.ScrollStrategy; public class selenium_shutterbug_fullpage_firefox { public static void main(String[] args) { System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe"); WebDriver driver = new FirefoxDriver(); driver.get("https://www.google.co.in"); Shutterbug.shootPage(driver, ScrollStrategy.BOTH_DIRECTIONS).save("./Screenshots/"); driver.quit(); } } Screenshot:

Python方法

以下是Python中截图的不同方法:

Using save_screenshot() method: Code block: from selenium import webdriver driver = webdriver.Chrome(r'C:\Utility\BrowserDrivers\chromedriver.exe') driver.get("http://google.com") driver.save_screenshot('./Screenshots/save_screenshot_method.png') driver.quit() Screenshot: Using the get_screenshot_as_file() method: Code block: from selenium import webdriver driver = webdriver.Chrome(r'C:\Utility\BrowserDrivers\chromedriver.exe') driver.get("http://google.com") driver.get_screenshot_as_file('./Screenshots/get_screenshot_as_file_method.png') driver.quit() Screenshot: Using get_screenshot_as_png() method: Code block: from selenium import webdriver driver = webdriver.Chrome(r'C:\Utility\BrowserDrivers\chromedriver.exe') driver.get("http://google.com") screenPnG = driver.get_screenshot_as_png() # Crop it back to the window size (it may be taller) box = (0, 0, 1366, 728) im = Image.open(BytesIO(screenPnG)) region = im.crop(box) region.save('./Screenshots/get_screenshot_as_png_method.png', 'PNG', optimize=True, quality=95) driver.quit() Screenshot:

Jython

import org.openqa.selenium.OutputType as OutputType
import org.apache.commons.io.FileUtils as FileUtils
import java.io.File as File
import org.openqa.selenium.firefox.FirefoxDriver as FirefoxDriver

self.driver = FirefoxDriver()
tempfile = self.driver.getScreenshotAs(OutputType.FILE)
FileUtils.copyFile(tempfile, File("C:\\screenshot.png"))

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();
            }

        }
    }

访问Snapshot using WebDriver获取更多详细信息。

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。

JavaScript (Selenium-Webdriver)

driver.takeScreenshot().then(function(data){
   var base64Data = data.replace(/^data:image\/png;base64,/,"")
   fs.writeFile("out.png", base64Data, 'base64', function(err) {
        if(err) console.log(err);
   });
});
