自动化测试时,遇到验证码问题怎么办?

前言:

目前看官们对“apache验证码”大致比较注意,我们都需要知道一些“apache验证码”的相关内容。那么小编在网上搜集了一些对于“apache验证码””的相关资讯,希望朋友们能喜欢,咱们快快来学习一下吧!

1.找开发人员去掉验证码或者使用万能验证码

2.使用OCR自动识别

使用OCR自动化识别,一般识别率不是太高,处理一般简单验证码还是没问题

这里使用的是Tesseract-OCR,下载地址:

怎么使用呢?

进入安装后的目录:

tesseract.exe test.png test -1

准备一份网页,上面使用该验证码

<html><head><title>Table test by Youngtitle>head><body> br><h1> Test h1> <img src=";> br>body>html>

要识别验证码,首先得取得验证码,这两款采取的是页面元素部分截图的方式,首先是获取整个页面的截图

然后找到页面元素坐标进行截取

/**     * This method for screen shot element     *      * @param driver     * @param element     * @param path     * @throws InterruptedException     */    public static void screenShotForElement(WebDriver driver,            WebElement element, String path) throws InterruptedException {        File scrFile = ((TakesScreenshot) driver)                .getScreenshotAs(OutputType.FILE);        try {            Point p = element.getLocation();            int width = element.getSize().getWidth();            int height = element.getSize().getHeight();            Rectangle rect = new Rectangle(width, height);            BufferedImage img = ImageIO.read(scrFile);            BufferedImage dest = img.getSubimage(p.getX(), p.getY(),                    rect.width, rect.height);            ImageIO.write(dest, "png", scrFile);            Thread.sleep(1000);            FileUtils.copyFile(scrFile, new File(path));        } catch (IOException e) {            e.printStackTrace();        }    }

截取完元素,就可以调用Tesseract-OCR生成text

// use Tesseract to get strings        Runtime rt = Runtime.getRuntime();        rt.exec("cmd.exe /C  tesseract.exe D:\\Tesseract-OCR\\test.png  D:\\Tesseract-OCR\\test -1 ");

接下来通过java读取txt

/**     * This method for read TXT file     *      * @param filePath     */    public static void readTextFile(String filePath) {        try {            String encoding = "GBK";            File file = new File(filePath);            if (file.isFile() && file.exists()) { // 判断文件是否存在                InputStreamReader read = new InputStreamReader(                        new FileInputStream(file), encoding);// 考虑到编码格式                BufferedReader bufferedReader = new BufferedReader(read);                String lineTxt = null;                while ((lineTxt = bufferedReader.readLine()) != null) {                    System.out.println(lineTxt);                }                read.close();            } else {                System.out.println("找不到指定的文件");            }        } catch (Exception e) {            System.out.println("读取文件内容出错");            e.printStackTrace();        }    }

整体代码如下:
