Gem Version

A Faraday middleware for adding request parameters to your exception tracker.



Add this line to your application's Gemfile:

gem 'faraday_error'

And then execute:

$ bundle

Or install it yourself as:

$ gem install faraday_error


Configure your Faraday connection to use this middleware. You can optionally specify a name; defaults to faraday. It is expected that you also use Faraday::Response::RaiseError somewhere in your stack.

connection = Faraday.new(url: 'http://localhost:4567') do |faraday|
  faraday.use       FaradayError::Middleware, name: "example_request"
  faraday.use       Faraday::Response::RaiseError
  faraday.adapter   Faraday.default_adapter

And that's it. Make a request as you normally would.

connection.post do |req|
  req.url '/503'
  req.headers['Content-Type'] = 'application/json'
  req.body = JSON.generate(abc: "xyz")

If any request fails, Honeybadger's "context" for this error will include your request parameters. If sending JSON or application/x-www-form-urlencoded, these will be included in parsed form.

  "example_request": {
    "method": "post",
    "url": "http://localhost:4567/503",
    "request_headers": {
      "User-Agent": "Faraday v0.9.2",
      "Content-Type": "application/json"
    "body_length": 13,
    "body": {
      "abc": "xyz"


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 tags, and push the .gem file to rubygems.org.

The included RestReflector Sinatra app is suitable for making requests that are guaranteed to fail in particlar ways.
