# IAAI Scraper # OpenLane Scraper
Парсер аукционных автомобилей с [iaai.com](https://www.iaai.com). Ходит по листингу, собирает карточки машин, вытаскивает данные из DOM и перехваченных XHR-ответов, складывает всё в PostgreSQL. Работает через Playwright, FastAPI, Celery и Docker. Парсер автомобилей с [OpenLane marketplace](https://app.openlane.com). Забирает данные через API (`GET /api/v4/search`), сохраняет в PostgreSQL. Работает через Playwright (для авторизации), FastAPI, Celery и Docker.
## Как устроен сайт и его защита ## Архитектура
У IAAI стоит **Imperva Incapsula** — внешний WAF и anti-bot. - **Авторизация**: Okta OAuth2 PKCE через `okta.iam.karglobal.com`. Сессия сохраняется в `storage_state.json` и переиспользуется между запусками.
- **Сбор данных**: API-запросы с заголовками `x-rbz-user-id`, `x-rbz-dealership-id` (извлекаются из JWT access_token).
- **Защита аккаунта**: throttle 2–5s между запросами, jitter 0–120s перед стартом, circuit breaker (2 ошибки подряд → стоп), 403→немедленный стоп, 429→backoff×3.
- **Anti-detection**: блокировка ресурсов (bugsnag, intercom, pusher, analytics), stealth patches.
- **Anti-bot** — headless Chromium без прокси часто режется. ## Локальный запуск
- **Динамическая подгрузка** — часть данных приходит через XHR (`/Search`, `/VehicleDetail`), часть остаётся в HTML.
- **Cookie consent** — при первом заходе показывают баннер.
Поэтому в проекте используются Playwright, паузы между действиями, прокси и сохранение браузерного состояния.
## Локальный запуск (без Docker)
### Требования ### Требования
- **Python 3.11+** - **Python 3.11+**
- **Git** - **PostgreSQL** и **Redis** (для Celery)
Docker **не нужен**. Данные хранятся в SQLite-файле `iaai_scraper.db` в корне проекта.
### Быстрый старт ### Быстрый старт
```bash ```bash
git clone <repo-url> git clone <repo-url>
cd iaai_scraper_project cd openlane_scraper_project
pip install -e . pip install -e .
playwright install firefox playwright install chromium
iaai init-db
```
`iaai init-db` актуален для SQLite/локального CLI-режима. Для PostgreSQL используйте Alembic-миграции (`alembic upgrade head` или сервис `migrate` в Docker). cp .env.example .env
# Заполнить OPENLANE_USERNAME, OPENLANE_PASSWORD в .env
Готовый `.env` уже в репозитории и настроен на SQLite ничего менять не нужно.
### Запуск парсера
**Скрапинг одной машины:**
```bash
iaai sync-vehicle "https://www.iaai.com/VehicleDetail/45089484~US"
```
**Сбор листинга + скрапинг (например Toyota, 10 штук):**
```bash
iaai sync-listing --make Toyota --limit 10
```
**Только ссылки с листинга (без скрапинга):**
```bash
iaai collect-listing --make Toyota
```
**С видимым браузером (для отладки):**
```bash
iaai --headless false sync-vehicle "https://www.iaai.com/VehicleDetail/45089484~US"
```
**Проверка, что записалось в базу (`iaai_scraper.db`):**
```bash
python -c "import sqlite3; c=sqlite3.connect('iaai_scraper.db'); q=c.cursor(); print('cars:', q.execute('select count(*) from cars').fetchone()[0]); print('images:', q.execute('select count(*) from images').fetchone()[0]); rows=q.execute('select id, brand, model, year, origin_id from cars order by id desc limit 10').fetchall(); [print(r) for r in rows]"
```
Результаты сохраняются в `artifacts/json/` и в БД `iaai_scraper.db`.
### Полный стек (API + Worker + Beat)
Для API и автоматического сбора нужны **Redis** и **PostgreSQL**. В `.env` раскомментируй строки Redis/Celery и замени БД на PostgreSQL:
```env
IAAI_DATABASE_URL=postgresql+psycopg2://iaai:iaai@localhost:5432/iaai_scraper
IAAI_REDIS_URL=redis://localhost:6379/0
CELERY_BROKER_URL=redis://localhost:6379/0
CELERY_RESULT_BACKEND=redis://localhost:6379/0
```
Применить миграции и запустить в трёх терминалах:
```bash
alembic upgrade head alembic upgrade head
```
### Запуск
```bash
# Терминал 1 — API # Терминал 1 — API
uvicorn iaai_scraper.api.app:app --reload --port 8000 uvicorn openlane_scraper.api.app:app --reload --port 8000
# Терминал 2 — Celery Worker # Терминал 2 — Celery Worker
celery -A iaai_scraper.worker.celery_app worker --loglevel=info --concurrency=1 --pool=solo -Q scraping celery -A openlane_scraper.worker.celery_app worker --loglevel=info --concurrency=1 --pool=solo -Q scraping
# Терминал 3 — Celery Beat (периодический запуск) # Терминал 3 — Celery Beat (каждый час)
celery -A iaai_scraper.worker.celery_app beat --loglevel=info celery -A openlane_scraper.worker.celery_app beat --loglevel=info
``` ```
API: `http://localhost:8000` · Swagger: `http://localhost:8000/docs` CLI:
--- ```bash
openlane scrape-openlane --limit 20
```
## Запуск через Docker (все сервисы в контейнерах) ## Docker
```bash ```bash
cp .env.example .env cp .env.example .env
docker compose up -d docker compose up -d
``` ```
Будут запущены сервисы `postgres`, `redis`, `migrate`, `api`, `worker`, `beat`. API доступен на `http://localhost:8000`. Сервисы: `postgres`, `redis`, `migrate`, `api`, `worker`, `beat`.
В Docker-образ дополнительно проверяется Python-синтаксис на этапе сборки (`python -m compileall -q iaai_scraper`), чтобы не выкатывать битый код.
`entrypoint.sh` поднимает SOCKS5→HTTP proxy bridge (если задан `SOCKS5_PROXY_HOST`) и запускает `Xvfb` только для `worker` и CLI scraping-команд. - `beat` запускает сбор **раз в 1 час** (`CELERY_BEAT_SYNC_INTERVAL_MINUTES=60`)
- Лимит по умолчанию: 20 машин (`OPENLANE_MAX_CARS_LIMIT=20`)
По умолчанию `beat` запускает сбор листинга **раз в 1 час** (`CELERY_BEAT_SYNC_INTERVAL_MINUTES=60`). API (Docker): `http://localhost:58000` · Swagger: `http://localhost:58000/docs`
Swagger-документация: `http://localhost:8000/docs` ### Первый логин (storage state)
```bash ```bash
docker compose ps docker compose run --rm --service-ports openlane-auth openlane openlane-login
# Войти вручную в браузере — storage state сохранится в volume
``` ```
- `api` имеет healthcheck на `GET /health`
- `worker` имеет healthcheck через `celery inspect ping`
- `beat` имеет healthcheck по файлу `celerybeat-schedule`
## API ## API
**Здоровье и статистика:** - `GET /health` — статус сервиса
- `GET /health` — статус сервиса и подключения к БД - `GET /api/v1/stats` — статистика (машины, картинки, топ брендов)
- `GET /api/v1/stats` — сколько машин и картинок в базе, топ брендов
**Машины:**
- `GET /api/v1/cars` — список с пагинацией - `GET /api/v1/cars` — список с пагинацией
- `GET /api/v1/cars/{id}` — карточка с картинками - `GET /api/v1/cars/{id}` — карточка с картинками
- `GET /api/v1/cars/by-origin/{origin_id}` — поиск по IAAI stock number - `POST /api/v1/tasks/sync-listing` — запустить сбор
**Задачи:**
- `POST /api/v1/tasks/sync-vehicle` — скрапнуть одну машину по URL
- `POST /api/v1/tasks/sync-listing` — запустить полный обход листинга
- `GET /api/v1/sync-runs` — история запусков - `GET /api/v1/sync-runs` — история запусков
Скрапим конкретную машину:
```bash
curl -X POST http://localhost:8000/api/v1/tasks/sync-vehicle \
-H "Content-Type: application/json" \
-d '{"vehicle_url": "https://www.iaai.com/VehicleDetail/45089484~US"}'
```
## CLI
Для отладки без API и Celery:
```bash
iaai init-db
iaai collect-listing --make Toyota
iaai sync-vehicle "https://www.iaai.com/VehicleDetail/45089484~US"
iaai sync-listing --limit 10
```
`iaai init-db` используйте для SQLite/локальных тестов. В PostgreSQL-сценарии применяйте миграции Alembic.
