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.

em-http-request is a Ruby gem for making asynchronous HTTP requests using EventMachine. It allows you to perform multiple requests simultaneously and handle the responses as they come in, rather than waiting for each request to complete before making the next one.

In short it supports: - Asynchronous HTTP API for single & parallel request execution - Keep-Alive and HTTP pipelining support - Auto-follow 3xx redirects with max depth - Automatic gzip & deflate decoding - Streaming response processing - Streaming file uploads - HTTP proxy and SOCKS5 support - Basic Auth & OAuth - Connection-level & global middleware support - HTTP parser via http_parser.rb - Works wherever EventMachine runs: Rubinius, JRuby, MRI

Example Use


# 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
EventMachine.run {
  http = EventMachine::HttpRequest.new('http://google.com/').get :query => {'keyname' => 'value'}

  # add callback for errors:
  http.errback { p 'Uh oh'; EM.stop }

  # add callback for successful requests
  http.callback {
    p http.response_header.status
    p http.response_header
    p http.response

    EventMachine.stop
  }
}
