Curl-cffi is a Python library for implementing curl-impersonate which is a HTTP client that appears as one of popular web browsers like: - Google Chrome - Microsoft Edge - Safari - Firefox Unlike requests and httpx which are native Python libraries, curl-cffi uses cURL and inherits it's powerful features like extensive HTTP protocol support and detection patches for TLS and HTTP fingerprinting.

Using curl-cffi web scrapers can bypass TLS and HTTP fingerprinting.

HTTPClient is a Ruby gem that provides a simple and flexible interface for making HTTP requests. It's a full-featured HTTP client library with support for cookies, redirects, proxy, and more. It's built on top of the libwww-perl library, which is a widely-used, robust and well-documented library.

Features:

  • methods like GET/HEAD/POST/* via HTTP/1.1.
  • HTTPS(SSL), Cookies, proxy, authentication(Digest, NTLM, Basic), etc.
  • asynchronous HTTP request, streaming HTTP request.
  • debug mode CLI.
  • by contrast with net/http in standard distribution;
  • Cookies support
  • MT-safe
  • streaming POST (POST with File/IO)
  • Digest auth
  • Negotiate/NTLM auth for WWW-Authenticate (requires net/ntlm module; rubyntlm gem)
  • NTLM auth for Proxy-Authenticate (requires 'win32/sspi' module; rubysspi gem)
  • extensible with filter interface
  • you don't have to care HTTP/1.1 persistent connection (httpclient cares instead of you)

Example Use


curl-cffi can be accessed as low-level curl client as well as an easy high-level HTTP client: ```python from curl_cffi import requests response = requests.get('https://httpbin.org/json') print(response.json()) # or using sessions session = requests.Session() response = session.get('https://httpbin.org/json') # also supports async requests using asyncio import asyncio from curl_cffi.requests import AsyncSession urls = [ "http://httpbin.org/html", "http://httpbin.org/html", "http://httpbin.org/html", ] async with AsyncSession() as s: tasks = [] for url in urls: task = s.get(url) tasks.append(task) # scrape concurrently: responses = await asyncio.gather(*tasks) # also supports websocket connections from curl_cffi.requests import Session, WebSocket def on_message(ws: WebSocket, message): print(message) with Session() as s: ws = s.ws_connect( "wss://api.gemini.com/v1/marketdata/BTCUSD", on_message=on_message, ) ws.run_forever() ```
```ruby require 'httpclient' client = HTTPClient.new # GET requests response = client.get("http://httpbin.org/get") puts response.content # POST requests data = { name: "value" } response = client.post("http://httpbin.org/post", data) puts response.content ```
