requestsvsexcon
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
Excon is a Ruby library for making HTTP requests. It is designed to be fast and efficient, and is often used as a building block for other Ruby libraries and frameworks.
One of the main features of Excon is its support for persistent connections, which allows it to reuse the same connection for multiple requests, reducing the overhead of establishing a new connection for each request.
Excon also supports streaming requests and responses, which allows you to read or write data to the server incrementally, without having to load the entire response into memory at once.
Highlights
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 'excon'
# GET requests
response = Excon.get('https://jsonplaceholder.typicode.com/posts/1')
puts response.body
puts response.status
puts response.headers
# POST requests
response = Excon.post('https://jsonplaceholder.typicode.com/posts',
:body => { :title => 'foo', :body => 'bar', :userId => 1 }.to_json,
:headers => { 'Content-Type' => 'application/json' } )
puts response.body
