Building a JSON API wrapper with Net::HTTP

Introduction

We're going to walk through building a simple API wrapper for jsontest. JSON Test is a sample API which is useful for testing API interactions.

There are 4 parts to this workshop:

• Writing a simple API wrapper
• Refactoring the wrapper
• Using metaprogramming to further refactor and simplify
• Using metaprogramming without method missing

We'll be using the following endpoints from JSON Test:

• IP Address
• Date and Time
• MD5

Example Usage

We want to use our API wrapper (client) like so:

api = Client.new('jsontest.com')
api.ip # => 8.8.8.8
api.date # => 03-02-2013
api.md5(text: 'testing') # => ae2b1fca515949e5d54fb22b8ed95575

And the program should output:

IP:
90.216.134.198
Date:
06-18-2015
MD5:
ae2b1fca515949e5d54fb22b8ed95575

Walk-through

Coding walk-through to be done in person with group.
