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
对于较新版本的Java, FileUtils函数不起作用。在这里,下面的功能可以完美地复制屏幕截图。
import java.io.File;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.io.FileHandler;
File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
File destfile = new File(destination folder /filename.extension);
FileHandler.copy(scrfile, destfile);
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"));
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。
C#
public void TakeScreenshot()
{
try
{
Screenshot ss = ((ITakesScreenshot)driver).GetScreenshot();
ss.SaveAsFile(@"D:\Screenshots\SeleniumTestingScreenshot.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
}
catch (Exception e)
{
Console.WriteLine(e.Message);
throw;
}
}
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:
