模拟登陆时，经常会遇到有验证码的问题，那么就需要把验证码给截取下来。

如下为截取验证码程序，该程序的原始地址为：[http://www.cnblogs.com/donaldlee2008/p/5304504.html][http_www.cnblogs.com_donaldlee2008_p_5304504.html]

有需要配置运行程序的请联系我：1563178220@qq.com

package login;
    
    import java.awt.image.BufferedImage;
    import java.io.File;
    import java.io.IOException;
    import javax.imageio.ImageIO;
    import org.apache.commons.io.FileUtils;
    import org.openqa.selenium.By;
    import org.openqa.selenium.OutputType;
    import org.openqa.selenium.Point;
    import org.openqa.selenium.TakesScreenshot;
    import org.openqa.selenium.WebDriver;
    import org.openqa.selenium.WebElement;
    import org.openqa.selenium.firefox.FirefoxDriver;
    
    
    public class Test1 {
    
        public static void main(String[] args) throws IOException {
            System.setProperty("webdriver.gecko.driver", "chrome\\geckodriver.exe");
            WebDriver driver = new FirefoxDriver();; 
              driver.get("http://weixin.sogou.com/antispider/?from=%2fweixin%3Ftype%3d2%26query%3dz+%26ie%3dutf8%26s_from%3dinput%26_sug_%3dy%26_sug_type_%3d");
              WebElement ele = driver.findElement(By.id("seccodeImage"));
              // Get entire page screenshot
              java.io.File screenshot = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
              BufferedImage  fullImg = ImageIO.read(screenshot);
              // Get the location of element on the page
              Point point = ele.getLocation();
              // Get width and height of the element
              int eleWidth = ele.getSize().getWidth();
              int eleHeight = ele.getSize().getHeight();
              // Crop the entire page screenshot to get only element screenshot
              BufferedImage eleScreenshot= fullImg.getSubimage(point.getX(), point.getY(),
                  eleWidth, eleHeight);
              ImageIO.write(eleScreenshot, "png", screenshot);
              // Copy the element screenshot to disk
              File screenshotLocation = new File("E:/钱洋个人/IdentifyingCode/test.png");
              FileUtils.copyFile(screenshot, screenshotLocation);
              WebElement classelement = driver.findElement(By.className("p2"));
              String errorText=classelement.getText();
              System.out.println("验证码"+classelement.getText());
    
          }
    }

如下，为我程序运行结果：

很神奇，网页中的验证码被成功截取到了本地。
