Create an HTTP Server in Go - Part 2
In this video, we walk through the implementation of a POST endpoint in Go that allows users to add items to an inventory system. Using Go’s http package, we will demonstrate how to handle requests securely and efficiently.
What You Will Learn:
How to implement a POST endpoint using Go's http package.
How to handle incoming JSON data from an HTTP request and decode it into a Go struct.
Implementing thread-safe access to shared resources using mutexes.
How to perform basic error handling for malformed requests and duplicate entries.
Code Walkthrough:
We will begin by setting up an HTTP handler for the /inventory/add_item endpoint.
You will see how to validate that only POST requests are accepted and return appropriate errors for invalid methods.
Learn how to decode the request body into an Item struct, and safeguard your inventory map against concurrent access.
We will also cover how to prevent duplicate items from being added and manage error handling in the event of bad requests.
