The Ruby Workshop

3.3 (3)
By: Akshat Paul, Philips, Dániel Szabó , Wallace

Overview of this book

The beauty of Ruby is its readability and expressiveness. Ruby hides away a lot of the complexity of programming, allowing you to work quickly and 'do more' with fewer lines of code. This makes it a great programming language for beginners, but learning any new skill can still be a daunting task. If you want to learn to code using Ruby, but don't know where to start, The Ruby Workshop will help you cut through the noise and make sense of this fun, flexible language. You'll start by writing and running simple code snippets and Ruby source code files. After learning about strings, numbers, and booleans, you'll see how to store collections of objects with arrays and hashes. You'll then learn how to control the flow of a Ruby program using boolean logic. The book then delves into OOP and explains inheritance, encapsulation, and polymorphism. Gradually, you'll build your knowledge of advanced concepts by learning how to interact with external APIs, before finally exploring the most popular Ruby framework ? Ruby on Rails ? and using it for web development. Throughout this book, you'll work on a series of realistic projects, including simple games, a voting application, and an online blog. By the end of this Ruby book, you'll have the knowledge, skills and confidence to creatively tackle your own ambitious projects with Ruby.

10. Ruby Beyond the Basics II

Activity 10.01: Implementing GET and POST Data to an External Server

Solution:

  1. We first require the gem, and then need to assign our GET request API to a url variable. We then make a GET call using httparty and display the response using an in-built method, parsed_response, which properly parses the JSON response:
    require 'httparty'
    url = 'https://www.akshatpaul.com/ruby-fundamentals/list-all-buildings'
    response = HTTParty.get(url)
    puts response.parsed_response
  2. Run this code from the Terminal using the following command:
    $ruby get_request.rb

    The output should be as follows:

    Figure 10.22: GET request output

    Figure 10.22: GET request output

    You can implement the same code without a third-party gem dependency by using the in-built net/http library and the JSON library. To try this, refer to the code in the get_request_net.rb file:

    require 'net/http'
    require 'json'
    url = 'https://www.akshatpaul.com/ruby-fundamentals/list-all-buildings...
