Ethon Impersonate is a fork of Ethon that wraps libcurl-impersonate.
In Greek mythology, Ethon, the son of Typhoeus and Echidna, is a gigantic eagle. So much for the history.
This allows you to make HTTP requests that appear to come from real browsers, helping to bypass bot detection and fingerprinting.
With bundler:
gem "ethon-impersonate"With rubygems:
gem install ethon-impersonateOn MacOS Apple Silicon, you need to install the following dependencies using Homebrew:
brew install libidn2 rtmpdump zstdNote: Homebrew must be loaded in the same arch than the Ruby interpreter. If you are using arch -x86_64 to run Ruby, you must also run Homebrew with arch -x86_64 brew install ....
Making the first request is simple:
easy = EthonImpersonate::Easy.new(url: "www.example.com")
easy.perform
#=> :okYou have access to various options, such as following redirects:
easy = EthonImpersonate::Easy.new(url: "www.example.com", followlocation: true)
easy.perform
#=> :okOnce you're done you can inspect the response code and body:
easy = EthonImpersonate::Easy.new(url: "www.example.com", followlocation: true)
easy.perform
easy.response_code
#=> 200
easy.response_body
#=> "<!doctype html><html ..."The main feature of this gem is the ability to impersonate real browsers. Use the impersonate method to configure the request to look like it's coming from a specific browser:
easy = EthonImpersonate::Easy.new(url: "www.example.com")
easy.impersonate("chrome136") # Impersonate Chrome 136
easy.perform
easy.response_code
#=> 200The gem supports all browser targets available in curl-impersonate. Some popular targets include:
- Chrome:
chrome136,chrome131_android - Firefox:
firefox135 - Safari:
safari184,safari184_ios - Edge:
edge101 - Tor:
tor145
For a complete list of available targets, see the curl-impersonate bin directory.
# Impersonate Chrome 136
easy = EthonImpersonate::Easy.new(url: "https://tls.browserleaks.com/json")
easy.impersonate("chrome136")
easy.perform
#=> :ok
# Impersonate Firefox 135
easy = EthonImpersonate::Easy.new(url: "https://tls.browserleaks.com/json")
easy.impersonate("firefox135")
easy.perform
#=> :ok
# Impersonate Safari 184
easy = EthonImpersonate::Easy.new(url: "https://tls.browserleaks.com/json")
easy.impersonate("safari184")
easy.perform
#=> :okIn order to make life easier, there are some helpers for making HTTP requests:
easy = EthonImpersonate::Easy.new
easy.http_request("www.example.com", :get, { params: {a: 1} })
easy.perform
#=> :okeasy = EthonImpersonate::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 = EthonImpersonate::Multi.new
easy = EthonImpersonate::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)
