How To Make HTTP Requests in Go

Introduction

When a program needs to communicate with another program, many developers will use HTTP. One of Go’s strengths is the breadth of its standard library, and HTTP is no exception. The Go net/http package not only supports creating HTTP servers, but it can also make HTTP requests as a client.

In this tutorial, you will create a program that makes several types of HTTP requests to an HTTP server. First, you will make a GET request using the default Go HTTP client. Then, you will enhance your program to make a POST request with a body. Finally, you will customize your POST request to include an HTTP header and add a timeout that will trigger if your request takes too long.
