Java Selenium(Chrome)载取滚动条网页长图的方法及示例代码

本文主要介绍Java使用Selenium操作Chrome等浏览器，载取带有滚动条的网页，载取网页完整长图的方法及示例代码。

1､下载指定版本Driver驱动

Firefox浏览器驱动：geckodriver
Chrome浏览器驱动：ChromeDriver
IE浏览器驱动：IEDriverServer
Edge浏览器驱动：MicrosoftWebDriver
Opera浏览器驱动：operadriver
PhantomJS浏览器驱动：phantomjs

2､安装引用Selenium

1) 下载Jar包

下载地址：http://docs.seleniumhq.org/download/

2) Maven安装



    org.seleniumhq.selenium
    selenium-java
    3.4.0

2､完整页面截图

import java.io.File;import java.io.IOException;import java.util.concurrent.TimeUnit;import javax.imageio.ImageIO;import org.openqa.selenium.WebDriver;import org.openqa.selenium.chrome.ChromeDriver;import org.testng.annotations.Test;import ru.yandex.qatools.ashot.AShot;import ru.yandex.qatools.ashot.Screenshot;import ru.yandex.qatools.ashot.shooting.ShootingStrategies;public class EntireScreenshot {    public static void main(String[] args) {        // TODO Auto-generated method stub    WebDriver driver;                System.setProperty("webdriver.chrome.driver", ".\\Driver\\chromedriver.exe");            driver=new ChromeDriver();            driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);            driver.manage().window().maximize();driver.get("https://www.wonhero.com/article/411/");          / /take screenshot of the entire page            Screenshot screenshot=new AShot().shootingStrategy(ShootingStrategies.viewportPasting(1000)).takeScreenshot(driver);            try {                ImageIO.write(screenshot.getImage(),"PNG",new File("path of the file"));            } catch (IOException e) {                // TODO Auto-generated catch block                e.printStackTrace();            }            driver.quit();        }    }

3､载取网页长图

改变窗口尺寸来截长图

import java.io.File;
import java.io.IOException;import java.util.concurrent.TimeUnit;import javax.imageio.ImageIO;import org.openqa.selenium.WebDriver;import org.openqa.selenium.chrome.ChromeDriver;import org.testng.annotations.Test;import ru.yandex.qatools.ashot.AShot;import ru.yandex.qatools.ashot.Screenshot;import ru.yandex.qatools.ashot.shooting.ShootingStrategies;public class EntireScreenshot {public static void main(String[] args) {// TODO Auto-generated method stubWebDriver driver;System.setProperty("webdriver.chrome.driver", ".\\Driver\\chromedriver.exe");driver = new ChromeDriver();try {driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);driver.manage().window().maximize();driver.get("https://www.wonhero.com/article/411/");                        //等待页面加载完成new WebDriverWait(driver, 300).until(driver -> ((JavascriptExecutor) driver).executeScript("return document.readyState").equals("complete"));JavascriptExecutor jexec = (JavascriptExecutor) driver;int width = (int) jexec.executeScript("return document.body.scrollWidth");int height = (int) jexec.executeScript("return document.body.scrollHeight");                        //设置浏览窗口大小driver.manage().window().setSize(new Dimension(width, height));Screenshot screenshot = new AShot().coordsProvider(new WebDriverCoordsProvider()).takeScreenshot(driver);BufferedImage image = screenshot.getImage();ImageIO.write(image, "PNG", new File("D:\\temp\\" + "AShot_BBC_Entire.png"));} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}driver.quit();}}

Maven引用依赖(ashot)：


    ru.yandex.qatools.ashot
    ashot
    1.5.4
