如何绕过验证码

无论人们多少次写道验证码早已过时,不再像开发者最初希望的那样有效,但是,互联网资源的所有者仍然继续使用验证码来保护他们的项目。但我们这个时代最流行的验证码是什么?

澄清 - 本文中介绍的所有代码都是基于验证码识别服务 2captcha 的 api 文档编写的

这是验证码。 recaptcha v2、v3 等,由 google 于 2007 年创建。自第一个 recaptcha 出现以来已经很多年了,但它仍然保持着花环,周期性地输给竞争对手,然后又赢回来。但尽管 recapcha 在神经网络面前存在诸多缺陷,但它的受欢迎程度从未达到第二位。

人们曾进行过大量创建“验证码杀手”的尝试,有些不太成功,有些看起来只是对验证码的威胁,但事实上却毫无作用。但事实仍然是,竞争对手希望做比 recapcha 更好、更可靠的事情,这表明了它的受欢迎程度。

如何使用python绕过recaptcha(代码示例)

如果您不信任任何第三方模块,我已经准备了最通用的代码,只需稍作修改即可插入您的python脚本中并自动解决验证码。这是代码本身:

导入请求
导入时间

api_key = 'your_api_2captcha_key'def solve_recaptcha_v2(site_key, url):    payload = {        'key': api_key,        'method': 'userrecaptcha',        'googlekey': site_key,        'pageurl': url,        'json': 1    }    response = requests.post('https://2captcha.com/in.php', data=payload)    result = response.json()    if result['status'] != 1:        raise exception(f"error when sending captcha: {result['request']}")    captcha_id = result['request']    while true:        time.sleep(5)        response = requests.get(f"https://2captcha.com/res.php?key={api_key}&action=get&id={captcha_id}&json=1")        result = response.json()        if result['status'] == 1:            print("captcha solved successfully.")            return result['request']        elif result['request'] == 'capcha_not_ready':            print("the captcha has not been solved yet, waiting...")            continue        else:            raise exception(f"error while solving captcha: {result['request']}")def solve_recaptcha_v3(site_key, url, action='verify', min_score=0.3):    payload = {        'key': api_key,        'method': 'userrecaptcha',        'googlekey': site_key,        'pageurl': url,        'version': 'v3',        'action': action,        'min_score': min_score,        'json': 1    }    response = requests.post('https://2captcha.com/in.php', data=payload)    result = response.json()    if result['status'] != 1:        raise exception(f"error when sending captcha: {result['request']}")    captcha_id = result['request']    while true:        time.sleep(5)        response = requests.get(f"https://2captcha.com/res.php?key={api_key}&action=get&id={captcha_id}&json=1")        result = response.json()        if result['status'] == 1:            print("captcha solved successfully.")            return result['request']        elif result['request'] == 'capcha_not_ready':            print("the captcha has not been solved yet, waiting...")            continue        else:            raise exception(f"error while solving captcha: {result['request']}")# usage example for recaptcha v2site_key_v2 = 'your_site_key_v2'url_v2 = 'https://example.com'recaptcha_token_v2 = solve_recaptcha_v2(site_key_v2, url_v2)print(f"received token for recaptcha v2: {recaptcha_token_v2}")# usage example for recaptcha v3site_key_v3 = 'your_site_key_v3'url_v3 = 'https://example.com'recaptcha_token_v3 = solve_recaptcha_v3(site_key_v3, url_v3)print(f"received token for recaptcha v3: {recaptcha_token_v3}")

但是,在使用提供的脚本之前,请仔细阅读用于识别特定类型的验证码的服务的建议,以便了解此代码的工作原理。

另外,不要忘记在代码中插入您的 api 密钥,当然,还要安装必要的模块。

如何绕过node js中的recaptcha

与 python 的情况一样,对于那些不喜欢现成解决方案的人,下面是使用 node js 编程语言解决验证码的脚本。我提醒您不要忘记安装代码运行所需的模块,包括:
axios

您可以使用此命令安装它 –

npm 安装 axios

这是代码本身:

const axios = require('axios');const sleep = require('util').promisify(settimeout);const api_key = 'your_api_key_2captcha'; // replace with your real api key// function for recaptcha v2 solutionasync function solverecaptchav2(sitekey, pageurl) {    try {        // sending a request for the captcha solution        const sendcaptcharesponse = await axios.post(`http://2captcha.com/in.php`, null, {            params: {                key: api_key,                method: 'userrecaptcha',                googlekey: sitekey,                pageurl: pageurl,                json: 1            }        });        if (sendcaptcharesponse.data.status !== 1) {            throw new error(`error when sending captcha: ${sendcaptcharesponse.data.request}`);        }        const requestid = sendcaptcharesponse.data.request;        console.log(`captcha sent, request id: ${requestid}`);        // waiting for the captcha solution        while (true) {            await sleep(5000); // waiting 5 seconds before the next request            const getresultresponse = await axios.get(`http://2captcha.com/res.php`, {                params: {                    key: api_key,                    action: 'get',                    id: requestid,                    json: 1                }            });            if (getresultresponse.data.status === 1) {                console.log('captcha solved successfully.');                return getresultresponse.data.request;            } else if (getresultresponse.data.request === 'capcha_not_ready') {                console.log('the captcha has not been solved yet, waiting...');            } else {                throw new error(`error while solving captcha: ${getresultresponse.data.request}`);            }        }    } catch (error) {        console.error(`an error occurred: ${error.message}`);    }}// function for recaptcha v3 solutionasync function solverecaptchav3(sitekey, pageurl, action = 'verify', minscore = 0.3) {    try {        // sending a request for the captcha solution        const sendcaptcharesponse = await axios.post(`http://2captcha.com/in.php`, null, {            params: {                key: api_key,                method: 'userrecaptcha',                googlekey: sitekey,                pageurl: pageurl,                version: 'v3',                action: action,                min_score: minscore,                json: 1            }        });        if (sendcaptcharesponse.data.status !== 1) {            throw new error(`error when sending captcha: ${sendcaptcharesponse.data.request}`);        }        const requestid = sendcaptcharesponse.data.request;        console.log(`captcha sent, request id: ${requestid}`);        // waiting for the captcha solution        while (true) {            await sleep(5000); // waiting 5 seconds before the next request            const getresultresponse = await axios.get(`http://2captcha.com/res.php`, {                params: {                    key: api_key,                    action: 'get',                    id: requestid,                    json: 1                }            });            if (getresultresponse.data.status === 1) {                console.log('captcha solved successfully.');                return getresultresponse.data.request;            } else if (getresultresponse.data.request === 'capcha_not_ready') {                console.log('the captcha has not been solved yet, waiting...');            } else {                throw new error(`error while solving captcha: ${getresultresponse.data.request}`);            }        }    } catch (error) {        console.error(`an error occurred: ${error.message}`);    }}// usage example for recaptcha v2(async () => {    const sitekeyv2 = 'your_site_key_v2'; // replace with the real site key    const pageurlv2 = 'https://example.com '; // replace with the real url of the page    const tokenv2 = await solverecaptchav2(sitekeyv2, pageurlv2);    console.log(`received token for recaptcha v2: ${tokenv2}`);})();// usage example for recaptcha v3(async () => {    const sitekeyv3 = 'your_site_key_v3'; // replace with the real site key    const pageurlv3 = 'https://example.com '; // replace with the real url of the page    const action = 'homepage'; // replace with the corresponding action    const minscore = 0.5; // set the minimum allowed score    const tokenv3 = await solverecaptchav3(sitekeyv3, pageurlv3, action, minscore);    console.log(`received token for recaptcha v3: ${tokenv3}`);})();

另外,不要忘记将您的 api 密钥插入代码中,而不是
“'your_api_key_2captcha'”

如何在 php 中识别 recapcha

好了,对于那些不习惯使用现成模块的人来说,这里是直接集成的代码。该代码使用标准 php 函数,例如 file_get_contents 和 json_decode,以下是代码本身:
