Overview of this book

Go Programming – From Beginner to Professional is a comprehensive guide that takes your proficiency in the Go programming language from novice to expert. Starting with fundamental concepts, this book covers variables, command-line tools, and working with data before delving into advanced concepts, including error handling, interfaces, and generics, harnessing Go’s latest features through hands-on exercises. Along the way, you’ll learn to structure projects using Go modules, manage packages effectively, and master debugging techniques. As you progress, you’ll get to grips with practical application-centric aspects such as command-line programming, file manipulation, and working with SQL databases. Additionally, the book explores web server development, RESTful APIs, and utilizing the Go HTTP client to interact with web applications. Further enhancing your Go skills, you’ll learn concurrent programming, testing methodologies, Go tools, and how to deploy applications in the cloud.

Structured data

Once you have requested data from a server, the data returned can come in various formats. For example, if you send a request to packtpub.com, it will return HTML data for the Packt website. While HTML data is useful for displaying websites, it isn’t ideal for sending machine-readable data. A common data type used in web APIs is JSON. JSON provides a good structure for data that is both machine-readable and human-readable. Later, you will learn how to parse JSON and make use of it using Go.

Exercise 17.02 – using the HTTP Client with structured data

In this exercise, you will parse structured JSON data in Go. The server will return JSON data, and you will use the json.Unmarshal function to parse the data and put them into a struct:

  1. Create a new directory, Exercise17.02. Within that directory, create two more directories, server and client. Then, within the server directory, create a file called server.go and write the following code:
