Simple HTTP Server Starter in 15 Minutes
--
This is a quick starter, to show some of the features of Go’s http library. (sample repo here) The docs for the library are located here if you want to dig in deeper. In this post however I cover putting together a simple http server with a video on creating the http server, setting a status code, which provides the basic elements you need to further build out a fully featured server. This post is paired with a video I’ve put together, included below.
00:15 Reference to the Github Repo where I’ve put the code written in this sample.
https://github.com/Adron/coro-era-coding-go-sample
00:18 Using Goland IDE (Jetbrains) to clone the repository from Github.
00:40 Creating code files.
01:00 Pasted in some sample code, and review the code and what is being done.
02:06 First run of the web server.
02:24 First function handler to handle the request and response of an HTTP request and response cycle.
04:56 Checking out the response in the browser.
05:40 Checking out the same interaction with Postman. Also adding a header value and seeing it returned via the browser & related header information.
09:28 Starting the next function to provide further HTTP handler functionality.
10:08 Setting the status code to 200.
13:28 Changing the status code to 500 to display an error.
Getting a Server Running
I start off the project by pulling an empty repository that I had created before starting the video. In this I use the Jetbrains Goland IDE to pull this repository from Github.
Next I create two files; main.go and main_test.go. We won't use the main_test.go file right now, but in a subsequent post I'll put together some unit tests specifically to test out our HTTP handlers we'll create. Once those are created I pasted in some code that just has a basic handler, using an…
