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.
HTTParty is a Ruby library that makes it easy to work with HTTP requests and responses. It is built on top of the Ruby standard library's Net::HTTP and provides a simple, easy-to-use interface for making requests and handling responses.
One of the main features of HTTParty is its ability to automatically parse response bodies as JSON, XML, or other formats. This allows developers to easily access the data returned by an API without having to manually parse the response.
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 'httparty'
# get request:
response = HTTParty.get('http://httpbin.org/get')
puts response.body
puts response.code
puts response.message
puts response.headers.inspect
# post request
response = HTTParty.post('http://httpbin.org/post',
:body => { :title => 'foo', :body => 'bar', :userId => 1 }.to_json,
:headers => { 'Content-Type' => 'application/json' } )
puts response.body
```
