This library captures HTTP(S) traffic made by net/http as HAR.

You can see examples of captured files here.

Add this line to your application's Gemfile:

gem 'har-net-http'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install har-net-http

To capture a HAR, load this library:

require 'har/net/http'

# Reset the har, so that future requests will create a new HAR
Har::Net::HTTP.har = nil

Then, make some HTTP requests. If you prefer, you can also make HTTP requests with higher level libraries such as faraday, http.rb, rest-client, httparty or any other library that is built on top of Ruby's net/http library.

When you're done, capture the HAR:

har = JSON.stringify(Har::Net::HTTP.har)

# Do what you want with it!

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
