我正在尝试使用phantomJS和ghostdriver截取页面。
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");
}
}
我在日志中遇到以下异常：

我能够获取元素数据，但在截屏时，错误即将来临。
请帮忙
答案 0 :(得分：2)
我调试并解决了问题。从代码中删除Augmenter后。它运作良好
