java - 屏幕截图不适用于 phantomJS 和 Ghostdriver

Question

我正在尝试使用 phantomJS 和 Ghostdriver 截取页面的屏幕截图。

这是我的代码:

import java.io.File;
import java.net.URL;

import org.apache.commons.io.FileUtils;
import org.openqa.selenium.By;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.phantomjs.PhantomJSDriver;
import org.openqa.selenium.phantomjs.PhantomJSDriverService;
import org.openqa.selenium.remote.Augmenter;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;

import net.anthavio.phanbedder.Phanbedder;

public class TakeScreenshot1 {
    public static File phantomjs = Phanbedder.unpack(); //Phanbedder to the rescue!

        public static void main(String args[]) throws Exception {
            DesiredCapabilities dcaps = new DesiredCapabilities();
            dcaps.setCapability("takesScreenshot", true);
            dcaps.setCapability(PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY, phantomjs.getAbsolutePath());

            PhantomJSDriver driver = new PhantomJSDriver(dcaps);
            driver.get("https://www.google.co.in");
            Thread.sleep(20000);

            WebElement element = driver.findElement(By.xpath("//*[@id=\"hplogo\"]"));
            System.out.println("Element is: "+ element.getText());

            System.out.println("Taking screenshot now");
            driver = (PhantomJSDriver) new Augmenter().augment(driver);
            File srcFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
            System.out.println("File:" + srcFile);
            FileUtils.copyFile(srcFile, new File("D:\\Java\\screenshot_.png"));
            System.out.println("Done");
        }
    }

我在日志中收到以下异常:

我调试并解决了这个问题。从代码中删除增强器后。效果很好
