//client = HttpClient
//captchaUserId = user id from http://2captcha.com

private String solveCaptcha(WebDriver driver) throws Exception{
        WebElement captchaChallenge = driver.findElement(By.id("recaptcha_challenge_image"));
        if (captchaChallenge != null){
            String imageURL = captchaChallenge.getAttribute("src");
            InputStream in = new BufferedInputStream(new URL(imageURL).openStream());
            ByteArrayOutputStream baos = new ByteArrayOutputStream();

            in.close();
            baos.flush();
            String base64Image = Base64.encodeBase64String(baos.toByteArray());
            baos.close();
            client.AddPostParam("body", base64Image);

                System.out.println("Captcha image sent");
            }
            else{
                System.err.println(client.getRawBody());
                return null;
            }
            String key = client.getRawBody().substring(client.getRawBody().indexOf("|") + 1, client.getRawBody().length());
            System.out.println("Captcha waiting key :" + key);

            do{
                client.Navigate(String.format("http://2captcha.com/res.php?key=%s&action=get&id=%s", captchaUserId, key));
                Thread.sleep(1000);
            } while(client.responseContains("NOT_READY"));
        }
        String captchaAnswer = null;
        if (client.responseContains("OK")){
            captchaAnswer = client.getRawBody().substring(client.getRawBody().indexOf("|") + 1, client.getRawBody().length());
            System.out.println("Captcha solved: " + captchaAnswer);
        }else{
            System.err.println("Captcha was not solved");
            System.err.println(client.getRawBody());
        } 
        return captchaAnswer;
    }

I also dont get this with the client... I have only tried it 10 minutes... Best regards

Can you please help me to resolve below errors:

1. Error at line "InputStream in = new BufferedInputStream(new URL(imageURL).openStream());" ---> BufferedInputStream cannot be resolved to a type

If I am not mistaken, it has to be imported. You can find out more about the package and class from the docs

2. What is client variable? What is meant by //client = HttpClient?

A class, responsible for handling the http requests. In my example, that was a custom implementation that I could not share. You can pretty much get the idea of what each function was meant to do by the function's name.

P.S. I switched to Node.js / React stack more than 3 years ago and haven't written a single line of code in java since then, so this example might be outdated or needs to be updated. I also do not follow the updates from java, so mentioned classes can potentially work differently / have different api / be removed from the core by this time.

Thanks for the interest in the gist, but I am not sure I will be able to help you out if you encounter any problems with this example of implementation
