requestsvshttp-2
The requests package is a popular library for making HTTP requests in Python.
It provides a simple, easy-to-use API for sending HTTP/1.1 requests, and it abstracts away many of the low-level details of working with HTTP.
One of the key features of requests is its simple API. You can send a GET request with a single line of code:
import requests
response = requests.get('https://webscraping.fyi/lib/requests/')
pip install requests
Pure Ruby, framework and transport agnostic, implementation of HTTP/2 protocol and HPACK header compression with support for:
- Binary framing parsing and encoding
- Stream multiplexing and prioritization
- Connection and stream flow control
- Header compression and server push
- Connection and stream management
- And more... see API docs
Protocol specifications:
- Hypertext Transfer Protocol Version 2 (RFC 7540)
- HPACK: Header Compression for HTTP/2 (RFC 7541)

Example Use
import requests
# get request:
response = requests.get("http://webscraping.fyi/")
response.status_code
200
response.text
"text"
response.content
b"bytes"
# requests can automatically convert json responses to Python dictionaries:
response = requests.get("http://httpbin.org/json")
print(response.json())
{'slideshow': {'author': 'Yours Truly', 'date': 'date of publication', 'slides': [{'title': 'Wake up to WonderWidgets!', 'type': 'all'}, {'items': ['Why <em>WonderWidgets</em> are great', 'Who <em>buys</em> WonderWidgets'], 'title': 'Overview', 'type': 'all'}], 'title': 'Sample Slide Show'}}
# for POST request it can ingest Python's dictionaries as JSON:
response = requests.post("http://httpbin.org/post", json={"query": "hello world"})
# or form data:
response = requests.post("http://httpbin.org/post", data={"query": "hello world"})
# Session object can be used to automatically keep track of cookies and set defaults:
from requests import Session
s = Session()
s.headers = {"User-Agent": "webscraping.fyi"}
s.get('http://httpbin.org/cookies/set/foo/bar')
print(s.cookies['foo'])
'bar'
print(s.get('http://httpbin.org/cookies').json())
{'cookies': {'foo': 'bar'}}
require 'http/2'
# GET request
client = HTTP2::Client.new
response = client.get("https://httpbin.org/get")
puts response.body
# POST reuqest
data = { name: "value" }
response = client.post("https://www.example.com", data)
