谷歌验证码，好几个版本，此处只针对于V2版本。

1、去网站 https://2captcha.com 注册，获取API  Key 。首次需要充值10美元。

2、https://2captcha.com/2captcha-api#solving_recaptchav2_new ，查看解决方案。 

3、这里使用 cdp4j 替代 selinum。最新版本4.0

4、代码如下。

import com.util.StringUtil;
import io.webfolder.cdp.Launcher;
import io.webfolder.cdp.session.Session;
import io.webfolder.cdp.session.SessionFactory;
import io.webfolder.cdp.session.SessionSettings;
import org.apache.commons.lang3.StringUtils;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;

public class RecaptchaV2 {

    public static String apiKey = "XXXXXX";
    public static String urlWithRecaptcha = "http://XXXXXX:8080/index3.html";

    public static void main(String[] args) {

        Launcher launcher = new Launcher();
        try (SessionFactory factory = launcher.launch();
            Session session = factory.create(new SessionSettings())) {
            session.navigate(urlWithRecaptcha);
            session.waitDocumentReady(60000);
            String content = session.getContent();

            System.out.println(content);
            String sitekey = getSitekey(content);
            System.out.println("sitekey = " + sitekey);

            // 2
            String url = "https://2captcha.com/in.php?key="+ apiKey +"&method=userrecaptcha&googlekey="+ sitekey +"&pageurl=" + urlWithRecaptcha;

            Document document = Jsoup.connect(url).get();
            System.out.println(document);

            String captchaId = StringUtils.substringAfter(document.text(), "OK|");
            System.out.println("captchaId = " + captchaId);


            // 3
            String documentText;
            do {
                Thread.sleep(5000);
                document = Jsoup.connect("http://2captcha.com/res.php?key="+ apiKey +"&action=get&id=" + captchaId).get();
                documentText = document.text();
            } while (!documentText.contains("OK"));
            String captchaResponse = StringUtils.substringAfter(documentText, "OK|");
            System.out.println("captchaResponse = " + captchaResponse);
            // 4

            session.setAttribute("#g-recaptcha-response", "style", "");

            session.setValue("#g-recaptcha-response", captchaResponse);

             Thread.sleep(5000);

　　　　　　　// 我自己注册了 google captcha, 前端页面我可以自己控制，这里abc，是页面 submit 元素的ID。
            session.click("#abc");
           
              Thread.sleep(5000);

        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            launcher.kill();
        }

    }

    /**
     * 获取 data-sitekey 值
     * @param content
     * @return
     */
    public static String getSitekey(String content) {
        if(content == null) {
            return null;
        }

        Element element = Jsoup.parse(content).selectFirst(".g-recaptcha");
        if(element == null) {
            return null;
        }

        return element.attr("data-sitekey");
    }
}

运行结果：

captchaId = 63048865558
captchaResponse = 03AOLTBLQOcQXQ3-QTGb0l9Z2b2KnyvjT8-DZCA6zRpNZhUclurh2myXZUoaTI9X55VpRLfeF3hR1Y3XqX5fKcAutEkkU4iIAztI9Q9v52a7wn4J0NVtVqp4YVotFIhQPDvSaEQogh4dh4cdybvWXDxrTHaezqIIUjAAgdw0C3GBAq3bKWh24hIJIfq5G7GWjIT9isCa0DcFLtEHbCZqQVXzdjDbVSx1uWFQzHxjAYkb4kQhM1qGsmFVbtaYz3ehlEtUMND7WMACxESIEQtf5IudEl6ODePgzMXSkuxDSvIFDN3xazYhxiRBfStI83MueCzDlnjcE6idpMhBWRG5A90ur6IXeV-qvMN8UOWoN3M6EUjW98GGI7VYZN_rL0TStf3qJPGDiUZ3qR7RRi0iKNzaMRSITjCbc4NXBlA0Fxqwmo_UY4lGh2XqkSI2_vUidyH3idgcR3tAKqTKOeRC0BLZb0FqdjUXLVw9Nny6aD8kZZNu33lKTy9wJurh7QlycvSgKxhWQH6Uof
