curlpro
HTTP-клиент с сетевым отпечатком браузера: TLS ClientHello, кадры HTTP/2, порядок и регистр заголовков.
import curlpro
curlpro.load_profiles("profiles")
with curlpro.Session("chrome-151-windows") as s:
r = s.get("https://example.com")
print(r.status, r.text[:200])
Зачем ещё один
Существующие решения хранят профили браузеров в компилируемом коде: новый Chrome выходит каждые 4 недели, и каждый раз это правка C или Go, пересборка и релиз. Здесь профиль — данные, и его можно подключить в рантайме:
curlpro.register_profile({
"name": "chrome-152-windows",
"based_on": "chrome-151-windows",
"headers": {"user_agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) ... Chrome/152.0.0.0 ..."},
})
Что внутри
Тонкая ctypes-обёртка над нативной библиотекой на Go: рукопожатие ведёт uTLS, HTTP/2 — fhttp.
Отпечаток сверен с tls.browserleaks.com: Chrome 151 даёт
t13d1516h2_8daaf6152771_806a8c22fdea — тот же JA4, что живой браузер.
Границы
Библиотека закрывает сетевой слой. Она не подделывает JS-отпечаток (canvas, WebGL, navigator) — это уровень браузера, там нужен Playwright. Совпадение сетевого отпечатка необходимо, но не достаточно: современные системы скорят JA4 вместе с JA4H, JA3S/JARM и поведенческим анализом.
Поддерживаются HTTP/1.1, HTTP/2, HTTP/3 и WebSocket, куки, редиректы, прокси (HTTP CONNECT и SOCKS5), multipart, потоковое чтение и отправка, асинхронный API.
# WebSocket: рукопожатие по шаблону профиля браузера, permessage-deflate поддержан
with curlpro.Session() as s:
with s.websocket("wss://echo.websocket.org/", max_message_size=1 << 20) as ws:
ws.send("привет") # str → текстовый кадр
ws.send(b"\x00\xff") # bytes → двоичный
for message in ws: # до закрытия сервером — curlpro.WebSocketClosed;
print(message) # таймаут тишины — CurlProError с .code == "timeout"
# Большой файл уходит потоком, а не через память
with curlpro.Session() as s:
s.post("https://example.com/upload", body_file="archive.zip")
# Соединение переиспользуется между запросами, как у браузера.
# keep_alive=False даёт каждому запросу своё — нужно, когда балансировщик
# прибивает клиента к одному узлу
with curlpro.Session(keep_alive=False) as s:
s.get("https://example.com/")
Отпечаток HTTP/3 сверен с Chrome 144 на quic.browserleaks.com:
with curlpro.Session("chrome-151-windows", http3=True) as s:
print(s.get("https://quic.browserleaks.com/fp").json()["h3_text"])
# 1:65536;6:262144;7:100;51:1;GREASE|GREASE|984832|m,a,s,p
Динамическая таблица QPACK поддержана своим декодером: профиль объявляет ёмкость, как Chrome, и ответ сервера, который ей пользуется, разбирается.
Установка
Пока собирается из исходников — нужны Go и C-компилятор:
.\build.ps1
cd python; $env:PYTHONPATH='.'; python -m pytest tests
Библиотека ищется по CURLPRO_LIBRARY, затем в curlpro/lib/, затем в dist/.
