In Greek mythology, Ethon, the son of Typhoeus and Echidna, is a gigantic eagle. So much for the history. In the modern world, Ethon is a very basic libcurl wrapper using ffi.
With bundler:
gem "ethon"
With rubygems:
gem install ethon
Making the first request is simple:
easy = Ethon::Easy.new(url: "www.example.com")
easy.perform
#=> :okYou have access to various options, such as following redirects:
easy = Ethon::Easy.new(url: "www.example.com", followlocation: true)
easy.perform
#=> :okOnce you're done you can inspect the response code and body:
easy = Ethon::Easy.new(url: "www.example.com", followlocation: true)
easy.perform
easy.response_code
#=> 200
easy.response_body
#=> "<!doctype html><html ..."In order to make life easier, there are some helpers for making HTTP requests:
easy = Ethon::Easy.new
easy.http_request("www.example.com", :get, { params: {a: 1} })
easy.perform
#=> :okeasy = Ethon::Easy.new
easy.http_request("www.example.com", :post, { params: { a: 1 }, body: { b: 2 } })
easy.perform
#=> :okThis is really handy when making requests since you don't have to care about setting everything up correctly.
Standard http2 servers require the client to connect once and create a session (multi) and then add simple requests to the multi handler.
The perform method then takes all the requests in the multi handler and sends them to the server.
See the following example
multi = Ethon::Multi.new
easy = Ethon::Easy.new
easy.http_request("www.example.com/get", :get, { http_version: :httpv2_0 })
# Sending a request with http version 2 will send an Upgrade header to the server, which many older servers will not support
# See below for more info: https://everything.curl.dev/http/http2
# If this is a problem, send the below:
easy.http_request("www.example.com/get", :get, { http_version: :httpv2_prior_knowledge })
# To set the server to use http2 with https and http1 with http, send the following:
easy.http_request("www.example.com/get", :get, { http_version: :httpv2_tls }
multi.add(easy)
