A Ruby library for the Battle.net Community Platform API

Build Status

Battlenet is a Ruby library that exposes Blizzard's Community Platform API.

Installing

Battlenet is available as a Ruby gem. Install it via

[sudo] gem install battlenet

Use

Simply create an instance of Battlenet, passing in an optional region as a symbol (defaulting to US), and then optionally a public and private key (for app authorization).

Default options:

api = Battlenet.new

Specifying a region:

api = Battlenet.new :eu

Specifying a public and private key:

api = Battlenet.new :us, 'public', 'private'

Battlenet is backed by the excellent HTTParty gem, which means you can make get requests very simply.

api.get '/item/12784'

Battlenet also provides modules for each section of the API, providing easy access to the resources.

api.item '12784'
api.character 'Nazjatar', 'Cyaga', :fields => "stats,talents,quests"

Configuring

Failing Silently

By default, if Battlenet receives a 4xx or 5xx response from the Battle.net API, it will throw a Battlent::ApiException. You can turn this behavior off via the fail_silently attribute:

Battlenet.fail_silently = true

The exception will have its code attribute set to the HTTP status code returned from the API; if the response included a JSON response with the reason field set, the exception will have a reason attribute set to this string. You can also access the raw response via the response attribute.

Localization

The Battle.net API supports localization via a query string parameter. Battlenet can transparently handle setting this parameter for you on every request. Just set the locale attribute:

Battlenet.locale = "en_GB"

Please note that each region only supports certain locales.

Battle.net API Documentation

The documentation for the Battle.net API can be found at http://blizzard.github.com/api-wow-docs/.

What's Missing

The following features are planned but not yet supported:

  • Caching support via Memcached, Redis, etc.
  • If-Last-Modified header support

Contributing

If you would like to contribute to the project, please feel free to do so. Just fork the project, commit your changes (preferably to a new branch), and then send me a pull request via GitHub. Be sure to add tests for your feature or fix.

Please do not change the contents of the VERSION file, or if you do, do so in a separate commit so that I can cherry-pick around it.

Setting Up the Development Environment

The development environment is managed with Bundler.

To install just the gems you need to hack on Battlenet and run the specs, run

bundle install --without documentation

To install all development gems, including the ones used to generate documentation, run

bundle install

To run the specs, run

bundle exec rake

Writing an Integration Test

High-level integration testing against the Community Platform API is handled via VCR. After the first time running a spec that hits the API, VCR saves the HTTP response in a fixture file and uses this file to run against in the future.

Here's an example (the character integration specs):

it "fetches character data" do
  VCR.use_cassette('character_mortawa') do
    character = api.character 'nazjatar', 'mortawa'
    character['level'].should == 85
  end
end

it "fetches additional character data" do
  VCR.use_cassette('character_mortawa_titles') do
    character = api.character 'nazjatar', 'mortawa', :fields => 'titles'
    character['titles'].find { |t| t['selected'] == true }['name'].should == "Twilight Vanquisher %s"
  end
end

it "fetches characters with non-ASCII characters in their name" do
  VCR.use_cassette('character_nonstandard_name') do
    character = api.character 'nazjatar', 'Hikô'
    character['level'].should == 85
  end
end

You should always wrap tests that hit the actual API in the VCR.use_cassette block, and the resulting fixture file should be checked in with your test.

Building the Documentation

If you have the necessary gems installed (defined in the documentation group in the Gemfile), you can easily generate the documentation via

yard

The generated documentation can be found in doc/; open doc/index.html to view it.
