Google reCAPTCHA v2 Callback 演示：使用 Google reCAPTCHA v2 Callback 的表单示例

在许多情况下，reCAPTCHA v2 Callback会妨碍无障碍访问，使用户感到沮丧，限制对公开信息的访问，使应用程序和网站的测试变得困难。使用 reCAPTCHA v2 Callback 解算器可自动绕过这些障碍。

如何破解reCAPTCHA v2回调

在浏览器中打开开发人员控制台，并找到带有data-sitekey属性的元素。

<div class="g-recaptcha" data-sitekey="6LfD3PIbAAAAAJs_eEHvoOl75_83eXSqpPSRFJ_u" id="recaptcha"></div>

发送 sitekey 和 pageurl 至我们的API.

使用SDK（推荐）：

PHP

// https://github.com/2captcha/2captcha-php

require(__DIR__ . '/../src/autoloader.php');

$solver = new \TwoCaptcha\TwoCaptcha('YOUR_API_KEY');

try {
    $result = $solver->recaptcha([
        'sitekey' => '6LfD3PIbAAAAAJs_eEHvoOl75_83eXSqpPSRFJ_u',
        'url'     => 'https://2captcha.com/demo/recaptcha-v2-callback',
    ]);
} catch (\Exception $e) {
    die($e->getMessage());
}

die('Captcha solved: ' . $result->code);

Python

# https://github.com/2captcha/2captcha-python

import sys
import os

sys.path.append(os.path.dirname(os.path.dirname(os.path.realpath(__file__))))

from twocaptcha import TwoCaptcha

api_key = os.getenv('APIKEY_2CAPTCHA', 'YOUR_API_KEY')

solver = TwoCaptcha(api_key)

try:
    result = solver.recaptcha(
        sitekey='6LfD3PIbAAAAAJs_eEHvoOl75_83eXSqpPSRFJ_u',
        url='https://2captcha.com/demo/recaptcha-v2-callback')

except Exception as e:
    sys.exit(e)

else:
    sys.exit('solved: ' + str(result))

Java

// https://github.com/2captcha/2captcha-java

package examples;

import com.twocaptcha.TwoCaptcha;

public class reCAPTCHAV2Example {
    public static void main(String[] args) {

        ReCaptcha captcha = new ReCaptcha();
        captcha.setSiteKey("6LfD3PIbAAAAAJs_eEHvoOl75_83eXSqpPSRFJ_u");
        captcha.setUrl("https://2captcha.com/demo/recaptcha-v2-callback");
        try {
            solver.solve(captcha);
            System.out.println("Captcha solved: " + captcha.getCode());
        } catch (Exception e) {
            System.out.println("Error occurred: " + e.getMessage());
        }
    }

            captcha.SetUrl("https://2captcha.com/demo/recaptcha-v2-callback");
            try

catch (std::exception & e)

    fprintf (stderr, "Failed: %s\n", e.what ());

return 0;   
}

Ruby

# https://github.com/2captcha/2captcha-ruby
require 'api_2captcha'

client =  Api2Captcha.new("YOUR_API_KEY")

result = client.recaptcha_v2({
  googlekey: '6Le-wvkSVVABCPBMRTvw0Q4Muexq1bi0DJwx_mJ-',
  pageurl: 'https://mysite.com/page/with/recaptcha_v2'
})

等待结果，结果可能如下所示：

手动操作：

发送GET或POST请求到我们的API URL: https://2captcha.com/in.php， method设置为userrecaptcha ，并提供上一步中找到的值作为googlekey的值，整页URL作为pageurl值。
请求示例：
GET https://2captcha.com/in.php?key=YOUR_API_KEY&method=userrecaptcha&googlekey=6LfD3PIbAAAAAJs_eEHvoOl75_83eXSqpPSRFJ_u&pageurl=http://2captcha.com/demo/recaptcha-v2-callback
如果一切正常，服务器将返回您的captcha ID：

OK|2122988149
否则服务器将返回错误代码.
1-2秒后发送GET请求以获取结果：

GET https://2captcha.com/res.php?key=YOUR_API_KEY&action=get&id=2122988149
如果captcha已破解，服务器将响应答案令牌：

OK|03AHJ_Vuve5Asa4koK3KSMyUkCq0vUFCR5Im4CwB7PzO3dCxIo11i53epEraq-uBO5mVm2XRikL8iKOWr0aG50sCuej9bXx5qcviUGSm4iK4NC_Q88flavWhaTXSh0VxoihBwBjXxwXuJZ-WGN5Sy4dtUl2wbpMqAj8Zwup1vyCaQJWFvRjYGWJ_TQBKTXNB5CCOgncqLetmJ6B6Cos7qoQyaB8ZzBOTGf5KSP6e-K9niYs772f53Oof6aJeSUDNjiKG9gN3FTrdwKwdnAwEYX-F37sI_vLB1Zs8NQo0PObHYy0b0sf7WSLkzzcIgW9GR0FwcCCm1P8lB-50GQHPEBJUHNnhJyDzwRoRAkVzrf7UkV8wKCdTwrrWqiYDgbrzURfHc2ESsp020MicJTasSiXmNRgryt-gf50q5BMkiRH7osm4DoUgsjc_XyQiEmQmxl5sqZP7aKsaE-EM00x59XsPzD3m3YI6SRCFRUevSyumBd7KmXE8VuzIO9lgnnbka4-eZynZa6vbB9cO3QjLH0xSG3-egcplD1uLGh79wC34RF49Ui3eHwua4S9XHpH6YBe7gXzz6_mv-o-fxrOuphwfrtwvvi2FGfpTexWvxhqWICMFTTjFBCEGEgj7_IFWEKirXW2RTZCVF0Gid7EtIsoEeZkPbrcUISGmgtiJkJ_KojuKwImF0G0CsTlxYTOU2sPsd5o1JDt65wGniQR2IZufnPbbK76Yh_KI2DY4cUxMfcb2fAXcFMc9dcpHg6f9wBXhUtFYTu6pi5LhhGuhpkiGcv6vWYNxMrpWJW_pV7q8mPilwkAP-zw5MJxkgijl2wDMpM-UUQ_k37FVtf-ndbQAIPG7S469doZMmb5IZYgvcB4ojqCW3Vz6Q
如果captcha未破解，服务器将返回 CAPCHA_NOT_READY结果。在5秒内重复您的请求。如果出现问题，服务器将返回错误代码.

在开发者控制台中，执行回调函数 verifyDemoRecaptcha，将令牌字符串作为参数传递，如下所示：verifyDemoRecaptcha('TOKEN')
请注意，每个网站都有专属reCAPTCHA植入方式，具有独特的回调定义，回调函数名称将与我们的演示不同，甚至使用匿名函数。此代码段可以帮助你找到回调定义。
