Java Selenium自动化识别图形验证码及短信验证模拟登录，并获取Cookies和页面内容

一、资源

1.下载谷歌模拟器驱动：http://npm.taobao.org/mirrors/chromedriver/

2.chromedriver的版本要与你使用的chrome版本对应，查看位置：设置->帮助->关于 Google

3.尖叫科技第三方验证码识别（这个效率比较高，如需账号可以与本人联系）：http://www.jianjiaoshuju.com/

二、抛出的问题

1.登录按钮不是链接，而是单击事件的时候，则用到了Selenium浏览器自动化框架，去模拟点击的操作。

2.当自己去写或者用免费的Tesseract-OCR4.0之类的识别验证码的工具需要投入较多的精力，时间成本太高。

三、解决的思路

1.Selenium模拟点击登录按钮，并获取验证码

2.第三方工具识别验证码

3.手输短信验证码，本地读取文本（前提手机号码是你的）

4.通过manage().getCookies();方法获取Cookies

5.指定body的xpath，获取页面内容

四、代码示例

1.工具类：根据图片地址转换为base64编码字符串

    /**
     * 根据图片地址转换为base64编码字符串
     * @param imgFile：图片地址
     * @return base64编码字符串
     */
    public static String getImageBase(String imgFile) {
        InputStream inputStream = null;
        byte[] data = null;
        try {
            inputStream = new FileInputStream(imgFile);
            data = new byte[inputStream.available()];
            inputStream.read(data);
            inputStream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
        // 加密
        BASE64Encoder encoder = new BASE64Encoder();
        return encoder.encode(data);
    }

 2.工具类：识别验证码的第三方api

    /**
     *
     * @param imgBase：图片的base64编码字符串
     * @param appcode：尖叫数据鉴权AppCode
     * @param appKey：尖叫数据鉴权AppKey
     * @param appSecret：尖叫数据鉴权AppSecret
     * @return 返回json串
     * 正常返回示例
     * {
     *   "msg": "查询成功!",
     *   "v_type": "ne4",
     *   "v_code": "37PW",
     *   "errCode": 0
     * }
     */
    public static String getImgCode(String imgBase, String appcode, String appKey, String appSecret) {

        String host = "http://apigateway.jianjiaoshuju.com";
        String path = "/api/v_1/yzm.html";
        String method = "POST";

        Map headers = new HashMap();
        Map querys = new HashMap();
        Map bodys = new HashMap();
        headers.put("appcode", appcode);
        headers.put("appKey", appKey);
        headers.put("appSecret", appSecret);
        headers.put("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
        bodys.put("v_pic", imgBase);
        bodys.put("v_type", "ne4");
        try {
            HttpResponse response = HttpUtils.doPost(host, path, method, headers, querys, bodys);
            System.out.println(response.toString());
            JSONObject jsonObject = GetHttpEntity(response);
            return jsonObject.getString("v_code");
        } catch (Exception e) {
            e.printStackTrace();
            return "第三方接口调用失败";
        }
    }

3.工具类：本地读取文本

    /**
     * @param filePath：本地短信验证码的txt文本路径
     * @return 短信验证码
     */
    public static String readTxt(String filePath) {
        String lineTxt = null;
        try {
            File file = new File(filePath);
            if(file.isFile() && file.exists()) {
                InputStreamReader isr = new InputStreamReader(new FileInputStream(file), "utf-8");
                BufferedReader br = new BufferedReader(isr);
                while ((lineTxt = br.readLine()) != null) {
                    return lineTxt;
                }
                br.close();
            } else {
                return "文件不存在!";
            }
        } catch (Exception e) {
            return "文件读取错误!";
        }
        return lineTxt;
    }

 4.Selenium模拟登录并获取数据
