This tutorial introduces the basics of writing a RESTful web service API with Go and the Gin Web Framework (Gin).

You’ll get the most out of this tutorial if you have a basic familiarity with Go and its tooling. If this is your first exposure to Go, please see Tutorial: Get started with Go for a quick introduction.

Getting Started

git clone https://github.com/deepakmardii/go-API

Next:

cd go-API

Install Gin:

go get github.com/gin-gonic/gin

From the command line in the directory containing main.go, run the code:

go run .

From a new command line window, use curl to make a GET request to your running web service.

curl http://localhost:8080/albums

or

curl http://localhost:8080/albums \
    --header "Content-Type: application/json" \
    --request "GET"
