如何在 Puppeteer 或 Selenium 中使用 Anti-Captcha 插件

Puppeteer 和 Selenium 是两个主要浏览器自动化引擎，而我们的插件则可紧密集成到这两个引擎中。本文将说明如何在 Puppeteer 和 Selenium 中将我们的插件分别用于 NodeJS 和 Python 编程语言。如果要在二者之间进行选择，则强烈建议选用 NodeJS+Puppeteer，因为其环境是原生态环境。

1. 安装所依赖的程序。对于 NodeJS，只须安装下面指定的 npm 程序包；对于 Python，请安装程序包并在此页面中下载可执行文件“chromedriver”。驱动程序版本必须与安装在系统中的 Chrome 版本相符。

Javascript

Python

npm install adm-zip puppeteer puppeteer-extra puppeteer-extra-plugin-stealth

2. 下载适用于 Chrome 的 ZIP 版插件，将其解压缩到项目文件夹中。实际版本位于此处。也可以编程的方式下载：

Javascript

Python

//npm install adm-zip
const https = require('https')
const fs = require('fs');
const AdmZip = require("adm-zip");

const pluginURL = 'https://antcpt.com/anticaptcha-plugin.zip';

(async () => {
    // 下载插件
    await new Promise((resolve) => {
        https.get(pluginURL, resp => resp.pipe(fs.createWriteStream('./plugin.zip').on('close', resolve)));
    })
    // 将其解压缩
    const zip = new AdmZip("./plugin.zip");
    await zip.extractAllTo("./plugin/", true);
})();

3. 然后在 ./plugin/js/config_ac_api_key.js 文件中配置 API 密钥。可在客户区找到 API 密钥。余额必须为正数才能使其起作用。

Javascript

Python

const apiKey = 'API_KEY_32_BYTES';
if (fs.existsSync('./plugin/js/config_ac_api_key.js')) {
    let confData = fs.readFileSync('./plugin/js/config_ac_api_key.js', 'utf8');
    confData = confData.replace(/antiCapthaPredefinedApiKey = ''/g, `antiCapthaPredefinedApiKey = '${apiKey}'`);
    fs.writeFileSync('./plugin/js/config_ac_api_key.js', confData, 'utf8');
} else {
    console.error('plugin configuration not found!')
}

4. 初始化装有插件的浏览器。对于 Puppeteer，建议将插件“puppeteer-extra-plugin-stealth”用于“puppeteer-extra”程序包，该插件可隐藏所有通过网络自动化 Chromium 浏览器的迹象。

Javascript

Python

//npm install puppeteer puppeteer-extra puppeteer-extra-plugin-stealth
const puppeteer = require('puppeteer-extra');
const StealthPlugin = require('puppeteer-extra-plugin-stealth');
puppeteer.use(StealthPlugin());

(async () => {
    const browser = await puppeteer.launch({
        headless: false,
        ignoreDefaultArgs: [
            "--disable-extensions",
            "--enable-automation"
        ],
        args: [
            '--disable-web-security',
            '--disable-features=IsolateOrigins,site-per-process',
            '--allow-running-insecure-content',
            '--disable-blink-features=AutomationControlled',
            '--no-sandbox',
            '--mute-audio',
            '--no-zygote',
            '--no-xshm',
            '--window-size=1920,1080',
            '--no-first-run',
            '--no-default-browser-check',
            '--disable-dev-shm-usage',
            '--disable-gpu',
            '--enable-webgl',
            '--ignore-certificate-errors',
            '--lang=en-US,en;q=0.9',
            '--password-store=basic',
            '--disable-gpu-sandbox',
            '--disable-software-rasterizer',
            '--disable-background-timer-throttling',
            '--disable-backgrounding-occluded-windows',
            '--disable-renderer-backgrounding',
            '--disable-infobars',
            '--disable-breakpad',
            '--disable-canvas-aa',
            '--disable-2d-canvas-clip-aa',
            '--disable-gl-drawing-for-tests',
            '--enable-low-end-device-mode',
            '--disable-extensions-except=./plugin',
            '--load-extension=./plugin'
        ]
    });
    const page = await browser.newPage();
})();

5. 转到目标网页并按需填写窗体。插件会自动获取 Recaptcha 谜题并开始对其进行破解。

Javascript

Python

(async () => {
    const url = 'https://anti-captcha.com/demo/?page=recaptcha_v2_textarea';
    const login = 'Test login';
    const password = 'Test password';

    try {
        await page.goto(url, {
            waitUntil: "networkidle0"
        });
    } catch (e) {
        console.error('err while loading the page: '+e);
    }
    // 禁止产生导航超时错误
    await page.setDefaultNavigationTimeout(0);

    await page.$eval('#login', (element, login) => {
        element.value = login;
    }, login);
    await page.$eval('#password', (element, password) => {
        element.value = password;
    }, password);

})();

6. 下一步有些棘手。对于某些网页窗体，用户必须在破解 Recaptcha 谜题后按提交按钮；其他窗体则采用回调的方式，自动提交网页窗体内容。对于第一种情况，我们需要在破解 Recaptcha 谜题后立即按提交按钮。要在合适的时间按提交按钮，只须等到选择器 .antigate_solver.solved 弹出后再按提交按钮即可。

Javascript

Python

// 等待“已破解”选择器弹出
await page.waitForSelector('.antigate_solver.solved').catch(error => console.log('failed to wait for the selector'));
console.log('{{ $t('articles.how-to-integrate.code-comments.recaptcha-solved') }}');

// 按提交按钮
await Promise.all([
    page.click('#submitButton'),
    page.waitForNavigation({ waitUntil: "networkidle0" })
]);
console.log('任务已完成，已绕过有 Recaptcha 谜题的窗体');

大功告成，窗体填写完毕，Recaptcha 谜题破解完毕并已绕过。全部代码的示例：

Javascript

Python

// first run the following to install required npm packages:
//
// npm install adm-zip follow-redirects puppeteer puppeteer-extra puppeteer-extra-plugin-stealth
//
//
const https = require('follow-redirects').https;
const fs = require('fs');
const AdmZip = require("adm-zip");

const apiKey = 'YOUR_API_KEY_HERE!';
const pluginURL = 'https://antcpt.com/anticaptcha-plugin.zip';
const url = 'https://anti-captcha.com/demo/?page=recaptcha_v2_textarea';
const login = 'Test login';
const password = 'Test password';
let page = null;


const puppeteer = require('puppeteer-extra');
const StealthPlugin = require('puppeteer-extra-plugin-stealth');
puppeteer.use(StealthPlugin());

(async () => {
    // 下载插件
    await new Promise((resolve) => {
        https.get(pluginURL, resp => resp.pipe(fs.createWriteStream('./plugin.zip').on('close', resolve)));
    })
    // 将其解压缩
    const zip = new AdmZip("./plugin.zip");
    await zip.extractAllTo("./plugin/", true);

    // 在配置文件中设置 API 密钥
    await new Promise((resolve, reject) => {
        if (fs.existsSync('./plugin/js/config_ac_api_key.js')) {
            let confData = fs.readFileSync('./plugin/js/config_ac_api_key.js', 'utf8');
            confData = confData.replace(/antiCapthaPredefinedApiKey = ''/g, `antiCapthaPredefinedApiKey = '${apiKey}'`);
            fs.writeFileSync('./plugin/js/config_ac_api_key.js', confData, 'utf8');
            resolve();
        } else {
            console.error('plugin configuration not found!')
            reject();
        }
    });

    // 设置浏览器启动选项
    const options = {
        headless: false,
        ignoreDefaultArgs: [
            "--disable-extensions",
            "--enable-automation"
        ],
        args: [
            '--disable-web-security',
            '--disable-features=IsolateOrigins,site-per-process',
            '--allow-running-insecure-content',
            '--disable-blink-features=AutomationControlled',
            '--no-sandbox',
            '--mute-audio',
            '--no-zygote',
            '--no-xshm',
            '--window-size=1920,1080',
            '--no-first-run',
            '--no-default-browser-check',
            '--disable-dev-shm-usage',
            '--disable-gpu',
            '--enable-webgl',
            '--ignore-certificate-errors',
            '--lang=en-US,en;q=0.9',
            '--password-store=basic',
            '--disable-gpu-sandbox',
            '--disable-software-rasterizer',
            '--disable-background-timer-throttling',
            '--disable-backgrounding-occluded-windows',
            '--disable-renderer-backgrounding',
            '--disable-infobars',
            '--disable-breakpad',
            '--disable-canvas-aa',
            '--disable-2d-canvas-clip-aa',
            '--disable-gl-drawing-for-tests',
            '--enable-low-end-device-mode',
            '--disable-extensions-except=./plugin',
            '--load-extension=./plugin'
        ]
    }

    try {
        // 启动装有插件的浏览器
        const browser = await puppeteer.launch();
        page = await browser.newPage();
    } catch (e) {
        console.log('could not launch browser: '+e.toString())
        return;
    }

    // 转到目标网页
    try {
        await page.goto(url, {
            waitUntil: "networkidle0"
        });
    } catch (e) {
        console.error('err while loading the page: '+e);
    }

    // 禁止产生导航超时错误
    await page.setDefaultNavigationTimeout(0);

    // 填写窗体
    await page.$eval('#login', (element, login) => {
        element.value = login;
    }, login);
    await page.$eval('#password', (element, password) => {
        element.value = password;
    }, password);

    // 等待“已破解”选择器弹出
    await page.waitForSelector('.antigate_solver.solved').catch(error => console.log('failed to wait for the selector'));
    console.log('{{ $t('articles.how-to-integrate.code-comments.recaptcha-solved') }}');

    // 按提交按钮
    await Promise.all([
        page.click('#submitButton'),
        page.waitForNavigation({ waitUntil: "networkidle0" })
    ]);
    console.log('Recaptcha 谜题已破解');

})();

还有一个窍门：无头模式中的插件运行很棘手，因为 Chrome 不支持通过插件进行的浏览器自动化。请使用名为 Xvfb 的实用工具，此工具可为您的应用程序提供虚拟桌面。

# 安装程序包
apt-get install -y xvfb

# 设置显示变量
export DISPLAY=:0

# 在后台启动 Xvfb 守护程序（只此一次）
/usr/bin/Xvfb :0 -screen 0 1024x768x24 &

# 稍等片刻，以使其弹出（只此一次）
sleep 5

# 对“node”或“python”脚本添加前缀“xvfb-run”
xvfb-run node myscript.js
# 或
xvfb-run python myscript.py
