Ekstraksi Parameter GeeTest v3 Slider dan Cara Solve

GeeTest v3 slider CAPTCHA memerlukan dua parameter untuk di-solve: gt (identifikasi situs statis) dan challenge (token sesi dinamis). Panduan ini menunjukkan cara mengekstrak keduanya dari halaman manapun dan mengirimkannya ke CaptchaAI.

Parameter GeeTest v3

Nilai gt tetap sama di semua request. Nilai challenge berubah setiap kali CAPTCHA dimuat — Anda harus mengekstrak nilai baru untuk setiap upaya solve.

Metode 1: Intercept API Call Register

Sebagian besar implementasi GeeTest v3 mengambil challenge dari endpoint registrasi. Responsnya terlihat seperti:

{
  "success": 1,
  "challenge": "a3f5c8d2e1b04a6789012345678abcdf",
  "gt": "019924a82c70bb123aae90d483b6a0ed",
  "new_captcha": true
}

Python (requests)

import requests
import re

session = requests.Session()
html = session.get("https://staging.example.com/qa-login").text

# Find the register endpoint
register_url = re.search(
    r'(https?://[^"\']+(?:register|captcha|geetest)[^"\']*)',
    html
)

if register_url:
    resp = session.get(register_url.group(1)).json()
    gt = resp["gt"]
    challenge = resp["challenge"]
    print(f"gt: {gt}")
    print(f"challenge: {challenge}")

JavaScript (Puppeteer: intercept network)

const puppeteer = require('puppeteer');

const browser = await puppeteer.launch();
const page = await browser.newPage();

let geetestParams = {};

page.on('response', async (response) => {
  const url = response.url();
  if (url.includes('register') || url.includes('captcha')) {
    try {
      const json = await response.json();
      if (json.gt && json.challenge) {
        geetestParams = {
          gt: json.gt,
          challenge: json.challenge,
        };
        console.log('Captured GeeTest params:', geetestParams);
      }
    } catch (e) {}
  }
});

await page.goto('https://staging.example.com/qa-login', { waitUntil: 'networkidle2' });
console.log('Final params:', geetestParams);

Metode 2: Ekstrak dari sumber halaman

Beberapa situs menyematkan parameter secara langsung dalam skrip HTML atau sebaris:

import re

# From data attributes
gt_match = re.search(r'data-gt=["\']([a-f0-9]{32})', html)
challenge_match = re.search(r'data-challenge=["\']([a-f0-9]{32})', html)

# From JavaScript variables
if not gt_match:
    gt_match = re.search(r'gt\s*[=:]\s*["\']([a-f0-9]{32})', html)
if not challenge_match:
    challenge_match = re.search(r'challenge\s*[=:]\s*["\']([a-f0-9]{32})', html)

gt = gt_match.group(1) if gt_match else None
challenge = challenge_match.group(1) if challenge_match else None
print(f"gt={gt}, challenge={challenge}")

Metode 3: Hook initGeetest

GeeTest v3 diinisialisasi via initGeetest(). Intercept sebelum skrip halaman dijalankan:

// Puppeteer: inject before page scripts
await page.evaluateOnNewDocument(() => {
  window.__geetestConfig = null;
  const origInit = window.initGeetest;

  Object.defineProperty(window, 'initGeetest', {
    set(fn) {
      this._initGeetest = function(config, callback) {
        window.__geetestConfig = config;
        console.log('GeeTest config:', JSON.stringify(config));
        return fn(config, callback);
      };
    },
    get() { return this._initGeetest; }
  });
});

await page.goto('https://staging.example.com/qa-login', { waitUntil: 'networkidle2' });

const config = await page.evaluate(() => window.__geetestConfig);
// config = { gt: "019924a...", challenge: "a3f5c8d...", product: "bind", ... }

Menyuntikkan Solusi GeeTest

Respons CaptchaAI untuk GeeTest v3 menyertakan challenge, validate, dan seccode:

# solution is a pipe-delimited string or JSON object
# Parse and inject into the form
import json

sol = json.loads(solution) if isinstance(solution, str) else solution

driver.execute_script("""
    const form = document.querySelector('form');
    function addHidden(name, value) {
        let input = form.querySelector(`input[name="${name}"]`);
        if (!input) {
            input = document.createElement('input');
            input.type = 'hidden';
            input.name = name;
            form.appendChild(input);
        }
        input.value = value;
    }
    addHidden('geetest_challenge', arguments[0]);
    addHidden('geetest_validate', arguments[1]);
    addHidden('geetest_seccode', arguments[2]);
""", sol["challenge"], sol["validate"], sol["seccode"])
