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.
Faraday is a Ruby gem that provides a simple and flexible interface for making HTTP requests. It allows you to create a Faraday connection object, which you can use to send requests and receive responses.
Faraday abstracts away the details of the underlying HTTP client library, so you can use it with different libraries such as Net::HTTP, HTTPClient, typhoeus and others.
Since Faraday can adapt many other HTTP clients it's very popular choice in web scraping.
Example Use
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
# GET requests
response = Faraday.get('http://httpbingo.org')
put response.status
put response.headers
put response.body
# or use a persistent client session:
conn = Faraday.new(
url: 'http://httpbin.org/get',
params: {param: '1'},
headers: {'Content-Type' => 'application/json'}
)
# POST requests
response = conn.post('/post') do |req|
req.params['limit'] = 100
req.body = {query: 'chunky bacon'}.to_json
end
