Bash + cURL + CaptchaAI: Otomatisasi CAPTCHA Shell
Gambar unggulan tidak tersedia

Skrip shell dengan cURL adalah cara paling portabel dan bebas ketergantungan untuk berinteraksi dengan API. Setiap sistem Linux/macOS telah menginstal Bash dan cURL. Saat tugas cron Anda, pipeline CI/CD, atau skrip pemantauan mencapai CAPTCHA, API HTTP CaptchaAI bekerja langsung dengan perintah cURL.

Panduan ini mencakup penyelesaian reCAPTCHA v2/v3, Cloudflare Turnstile, dan gambar CAPTCHA menggunakan Bash murni – tanpa memerlukan Python, Node.js, atau runtime lainnya.

Mengapa Bash + cURL untuk Pemecahan CAPTCHA

  • Tanpa ketergantungan – Bash dan cURL dikirimkan bersama setiap sistem Linux/macOS
  • Ringan – tanpa runtime, tanpa manajer paket, tanpa langkah instalasi
  • Ramah cron – menjadwalkan tugas yang bergantung pada CAPTCHA dengan cron standar
  • CI/CD siap - berfungsi di Docker, GitHub Actions, Jenkins, GitLab CI
  • Siap pipa — penyelesaian CAPTCHA berantai dengan jq, grep, awk, dan alat lainnya

Prasyarat

  • Pesta 4.0+
  • cURL (diinstal secara default di Linux/macOS)
  • jq untuk penguraian JSON: apt install jq atau brew install jq
  • Kunci API CaptchaAI (dapatkan satu di sini)

Fungsi Inti

Kirim Tugas

#!/bin/bash

    local api_key="$1"
    shift

    local response
    response=$(curl -s -X POST "${CAPTCHAAI_URL}/in.php" \
        -d "key=${api_key}" \

Pemecahan Masalah

Kesalahan Penyebab Solusi
ERROR_WRONG_USER_KEY Kunci API tidak valid Verifikasi kunci di dasbor
ERROR_ZERO_BALANCE Tidak ada dana Isi ulang akun
curl: (60) SSL certificate Paket CA hilang Tambahkan --cacert /path/to/ca-bundle.crt atau -k untuk pengujian
jq: command not found jq tidak diinstal apt install jq atau brew install jq
base64: invalid option -- 'w' Sintaks base64 macOS Gunakan base64 file bukan base64 -w 0 file
Respons kosong Masalah jaringan Tambahkan flag -v ke curl untuk debugging

Pertanyaan Umum

Apakah saya perlu jq?

Untuk penguraian JSON, ya. Alternatifnya, Anda dapat menggunakan grep dan sed untuk mengekstrak nilai, namun jq jauh lebih dapat diandalkan.

Apakah ini berfungsi di macOS?

Ya, tetapi perhatikan bahwa macOS menggunakan base64 versi BSD dan alat lainnya. Skrip ini menangani sintaksis Linux dan macOS base64.

Bisakah saya menggunakan ini di wadah Docker?

Ya. Alpine Linux dengan bash, curl, dan jq membuat container minimal (~10MB) untuk otomatisasi CAPTCHA.

Bagaimana cara menyimpan kunci API dengan aman?

Gunakan variabel lingkungan: export CAPTCHAAI_KEY="..." dan referensi $CAPTCHAAI_KEY dalam skrip. Jangan pernah melakukan hardcode kunci dalam file yang dikontrol versi.
